        OVERVIEW OF COURSE CONTENT AND OBJECTIVES

 In accordance with the 1986 Asbestos Hazard Emergency Response Act (AHERA). the
 Environmental  Protection Agency (EPA)  promulgated regulations which  established
 training and examination requirements for various disciplines associated with asbestos
 hazard evaluation and  control in schools.   These disciplines include  inspectors,
 management  planners,  project designers,  abatement contractors/supervisors and
 abatement workers.  The training requirements also delineate the topics which must be
 included in the curricula for each discipline and the minimum number of days for each
 course presentation.

 EPA  established five regional university training  centers to serve as sources of the
 required training programs.  A mechanism was also established for  approving training
 entities. Currently, approval of training providers is conducted at the state level.  EPA also
 provided funding to develop model curricula for each of the disciplines which Includes a
 student manual, instructor's manual and visual aids.  These curricula are available from
 National Technical  Information Service (NTIS) at 704-487-4650. for a nominal fee.

 This student manual is the EPA model curriculum developed for asbestos abatement
 project designers.  As a matter of interest the portion of the Model Accreditation Plan (40
 CFR Part 763) that applies to project designers has been excerpted from the Thursday.
 April 30. 1987, Federal Register and included at the end of this section.  Thfe curriculum
 covers all the topics listed in the model accreditation plan with the exception that a design
 workshop has been substituted for a field trip. While  the model plan requires a  minimum of
 three days training  tor project designers, four days is recommended to adequately cover
the contents of this manual.

                                                                              Pag* 2
As with other EPA model curricula, there is  no mandatory prerequisite training  or
qualifications required for those attending this course. However, EPA recommended and
several states have established additional  qualifications for project designers such as
being a registered architect, engineer or certified  industrial hygienist Because there is no
EPA prerequisite, the  model curriculum provides background information on asbestos
including physical characteristics, uses and health effects.

A  review of the Table of Contents indicates this curriculum consists of twelve  additional
sections that will  be covered in lectures with slides and overhead transparencies; and a
design laboratory which will provide students with hands-on opportunity to design a project
by solving a series of design problems.  Study questions are provided at the end of each
section to help students focus on the most important  information and prepare for the
required exam.

There  are several advantages to  using an AH ERA accredited project designer for all
asbestos abatement projects. Furthermore, accredited designers are mandatory for some
projects.  For example, EPA/AHERA regulations 40 CFR 763.91  require accredited
asbestos project designers for the following projects in schools (grades K-12):

       •  'any maintenance activities  disturbing  friable ACBM, other than small-scale.
         short-duration maintenance activities';

       •  the response action for any major fiber  release episode.*

 The Asbestos School Hazard Abatement Reauthortzation Act (ASMARA) which took effect
 on November 28, 1992, has extended the requirement for using an AHERA accredited
 project designer to design response actions in public and commercial buildings, as well as
 schools.

 These course materials are intended to help project designers generate and enforce
 written specifications and project plans which meet or exceed federal regulations  and
 other appropriate criteria.

 Written   specifications  are  necessary  to  ensure  a  successful  abatement
 project, regardless  of the size, and are necessary to establish the scope of work, set
 parameters for how the project is done, and set the criteria for determining when the work
 is completed. The specifications should help minimize at  least five potential problems
 which can be involved with asbestos abatement projects:  health, pubGcity, government
 regulations,  contract disputes and law  suits.   These potential problems cannot  be
 eliminated by merely  having the contractor comply with federal, state and local regulations.
 In some cases, more stringent criteria are needed to provide  adequate protection of the
 involved parties during the projects. The course material cites  several instances where
 this is the case.

 There are various types or styles of design specifications.  If the designer chooses to
 specify exactly how the  work must be set up, done and completed,  then they are called
 "means and methods"  style of specifications.  If the specifications state what must be
 accomplished, basic limitations of performance and criteria for measuring completion, then
they are called "performance" style of specifications. Furthermore,  specifications which
 list brand names are  called "proprietary" and those which  do  not  are  called

"nonproprietary." Each style has some advantages and  some disadvantages which are
presented as part of the notebook materials and lectures.  Most specifications are a mix of
several styles.

The objective  of  the  curriculum  is to provide students with fundamental technical
information related to asbestos abatement project  design that can be incorporated into
written specifications.   This information may  be augmented by  additional project
experiences and current events interjected by the presenters.  It is not presumed that a
three-  or  four-day  training program can  provide all of the  information or experience
necessary to correctly design an asbestos abatement project.  The  information In this
course will serve as a technical supplement on asbestos work practices to those who are
already designing projects and as a basic primer on design techniques for those who are
familiar with asbestos issues but have limited design experience.

Using the  Manual

There  is a glossary in  the Appendix of this manual which covers most of the important
terms and definitions.  Throughout the manual  these terms are underlined to remind the
reader they are in  the glossary.  Important words and  phrases have been highlighted in
bold print throughout the manual to help focus the reader's attention. Also, questions are
provided at the end of each section to provide a review of important information.

                      BACKGROUND  INFORMATION
 INTRODUCTION

 Many factors  must be evaluated before deciding to conduct an  asbestos  abatement
 project. This section is intended to provide the project designer with insight into a variety of
 asbestos-related  issues that  ultimately  influence  the  design  process.    These
 considerations range from  the  fundamentals of locating and  identifying asbestos-
 containing materials to the tasks of assessing the potential hazard and selecting the most
 appropriate response action.

 In schools,  the project designer will be coordinating efforts with the  local education
 agency's (LEA) designee who  Is responsible for short and long term management
 planning to control asbestos hazards. Although there is no regulatory requirement for a
 designated  asbestos coordinator in  commercial and  public buildings and industrial
 facilities, often a staff person has been appointed.

 DESCRIPTION OF ASBESTOS

Asbestos is a generic term which includes a number of fibrous minerals. The various types
of asbestos minerals occur predominantly in  metamorphic rock where they crystallize in
narrow veins as parallel bundles of tiny fibers. A fiber bundle may contain as  many as a
milion of the minute fibrils. When dispersed into the air. these fibrils may remain airborne
for several hours.  Three distinctive characteristics of asbestos fibers are apparent when
viewed  under  a microscope.  Asbestos fibers are  very small, they are much

                                                                            Pago 2

longer than they are wide and there  Is a  noticeable variation In  diameter of
the  Individual  fibrils.
The different  types  of asbestos are  placed into two  mineralogic categories termed
serpentines and amphiboles. Minerals in these groups are distinguished by their chemical
composition and  their crystalline structure.  Serpentines and amphiboles exhibit
different physical  properties which are Important from a  project  designer's
viewpoint.  For example, the amphiboles do not wet as easily as the serpentines.
Therefore, it may be more difficult to  keep airborne  fiber levels down when removing
materials containing amphibole asbestos material.

The only fibrous asbestos in the serpentine group is chrysolite, sometimes referred to as
white asbestos. It comprises more than 90 percent of all the asbestos that has been used
in commercial products in the Unites Stales. The primary elements in chrysolite are silicon
and magnesium.  Chrysotile also usually contains impurities  of iron, nickel,  aluminum,
chrome and some other minerals. The chrysotile fibril is a spirally-wound hollow tube.  The
combination of fforils bound together gives the fiber the appearance of having curly split
ends.  Chrysotile fibers have high tensile strength and good spinnability but  are  not as
resistant to acids as the amphiboles.

The fibrous  asbestos minerals in the amphibole group  are  actinolite, amosite,
anthophyllite, croddolite and tremolite.  They are characterized by a wide variation in
chemical composition including calcium, sodium, aluminum, ferrous and  ferric iron.
Amosite  and  crocldollte,  sometimes referred to as  brown  and blue  asbestos,
respectively, are the only commercially significant varieties.  When compared to chrysotile
in appearance, amosite and crocktolite fibers are larger in diameter, solid as opposed to

 hollow and straight instead of curly.  The amphiboles are more resistant to acids than
 chrysotile and can withstand higher temperatures without breaking down.
 ASBESTOS-CONTAINING PRODUCTS

 To obtain  asbestos for commercial  use, asbestos ore  is extracted from  open pit or
 underground mines. The ore is crushed and the asbestos fibers are separated from the
 rock layers by vbrating screens and an air-lifting process.  The fibers are bagged in bulk
 for incorporation into various products  at manufacturing facilities or through on-site mixing.
 Asbestos-containing  materials which  are batch-mixed  on  the construction
 site,  such  as  structural flreprooflng, usually have  a wider variation  in
 percentage  of asbestos content  than  those  that  are  Incorporated  into
 manufactured products,  such  as  floor  tile.  The type of material and method of
 production  have a bearing on the  number of samples  that must be collected for a given
 suspect material in a building survey.

 The various types of asbestos have been incorporated into  an estimated 3.000 commercial
 products. The Inherent physical characteristics such as resistance to heat and chemicals.
 abrasion resistance, insulating capabilities and high tensile strength along with low cost
 and availability, resulted in the widespread use  of asbestos-containing materials (ACM).
Asbestos was commonly used on steam pipes and boilers of ships during the early 1900s.
 It was used widely in American ships  and shipyards in the 1940s and was expanded to
include sprayed-on insulation materials in the 1950-1970s.  Use of asbestos in the United
States did not begin to decline until the 1973-1978 bans by the Environmental Protection
Agency (EPA) on spray-applied and premolded friable buiding materials.

Asbestos abatement project designers will be primarily involved with several common
asbestos materials that were incorporated into building products. These products can be
described in terms of use  such as fireproofing. thermal and  acoustical insulation,
decorative application, product reinforcement, and acid resistance.  For the purposes of
evaluating asbestos in buildings, the EPA has  defined three categories of asbestos-
containing building materials based upon application.

       •  SURFACING  MATERIALS - ACM sprayed or troweled on surfaces (walls,
         ceilings, structural members) for acoustical, decorative, thermal insulation or
         fireproofing purposes.

       •  THERMAL SYSTEM INSULATION  (TSI) - Insulation used to inhibit heat
         transfer or prevent condensation on pipes, boilers, tanks, ducts and various other
         components  of hot and cold water systems, and heating, ventilation, and air
         conditioning (HVAC) systems. This includes pipe lagging, pipe wrap; block,  batt
         and blanket insulation; cements and 'muds'; and a variety of other products such
         as gaskets and ropes.

       •  MISCELLANEOUS  MATERIALS  - Materials not included in the other two
         categories such as floor tile, ceiling tile, roofing felt, concrete pipe, outdoor siding
         and fabrics, sheetrock 'mud,' glazing putty, various mastic products and caulking
         products.   Frequently, nonbuilding  ACMs  such as material in  ovens and
         laboratory counter tops must be addressed in the project design.

The terms friable and nonfriable  are used to further describe the cohesiveness and
consistency of asbestos-containing materials.  Friable ACM,  when dry, can  be

 crumbled or  reduced to powder by  normal  hand pressure.   Friable materials
 generally release fibers into the air more readily than do nonfriable materials.  However,
 many types of nonfrlable  ACM can become friable  and  release  fibers if they  are
 substantially broken, cut. driBed, sanded, sandblasted, crushed, pulverized, or abraded.

 COMMON TYPES OF ACM INVOLVED IN PROJECT DESIGN

 The materials most likely to be involved in an asbestos abatement design project are
 spray-applied fireproofing. acoustical plaster, ceiling tile, thermal system  Insulation, floor
 tile and associated mastic.  A brief discussion of these materials follows and a listing of a
 wide variety of asbestos-containing products is provided in Table 11-1.

 Spray-Applied  Fireproofing -   A  one-half to two-inch thick layer of friable asbestos-
 containing insulation was commonly spray-applied to the structural steel in a building to
 prevent buckling and collapse during a fire.  Sometimes it was also spray-applied  to the
 floor and roof decks.  Chrysolite,  In quantities of 1  to 95 percent (25 percent  on
 average), is  the  most  common type of asbestos found   In fireproofing
 Insulation.   Occasionally amoslte  or  rarely  crocldollte  were used.    Other
 materials typically used in conjunction with chrysotJle included  vermiculite. cellulose  ftoers,
 gypsum and binders such as calcium carbonate  and  portJand cement

 Asbestos-containing fireproofing was usually spray  applied to the structural steel before
the installation of other building components and may be located in hard-to-access places
such as elevator shafts, fresh-air ventilation shafts and beams covered up by duct work.
There Is usually overspray on everything that was present at the time of application.  It may
be on the inside of some electrical and/or air conditioning ducts if they were partiafly in

place when the  fireprooling was applied.  Cverspray may be found on  exterior walls

behind insulation on gypsum board and finish materials. Asbestos-containing fireproottng

ranges from white to gray to brown as it was applied, but sometimes may be coated or

encapsulated with a dear or colored sealant

 Acoustical Plaster - Acoustical plaster typically containing 10 to 30 percent chrysolite was
 commonly troweled or sprayed onto walls or ceilings for soundproofing.  The material is
 typically one-fourth to one-half inch in thickness, friable, and varies in color from white to
 gray. Acoustical material is usually accessible because it is used to reduce noise levels in
 frequently occupied areas such as hallways, auditoriums and cafeterias, but may also be
 inside electrical ducts, conduits and air conditioning ducts that were in place when the
 material was installed or  inside of walls.  Even In accessible locations where the
 acoustical ACM has been painted,  It Is still a friable material which would
 need to be addressed  upon renovation or demolition  and In the operations
 and maintenance program.

 Thermal  System  Insulation  -  Thermal system insulation (TSI) is the category which
 contains the largest amount of  ACM.  In commercial buildings and schools, most of the
 material is generally limited to closed, restricted access areas rather than offices or highly-
 used space. However, in  industrial facilities, accessible TSI is much more predominant
 The average percentage of asbestos in TSI ranges from 65 to 75 percent ft often contains
 crocktolite and amosite as  well as chrysotie.

 Insulation on thermal systems is typically wrapped with an outer canvas jacketing and may
 be  applied  as a  corrugated cardboard-type pipe wrap,  a  white chalky pipe wrap,
 cemantitious mud around pipe fittings, block insulation on boilers, white batt insulation on
 boiler breeching, or as black batt insulation inside ducts. On tanks and boilers there may
 be  layers of other materials such as wire mesh  sandwiched between  the  layers of
 insulation.  Removal of TSI may pose special problems if it is insulating high-temperature
 lines, high pressure lines, or lines containing toxic chemicals.  TSI used in  occupied
spaces such as insulation  on  exposed pipe risers in public areas is more accessible and

may require additional surveillance and preventative maintenance to ensure the material
remains in good condition.
Floor Tlte and Mastic - Floor tile and the underlying mastic are generally considered to be
nonfriabie materials when they are in good condition.  These materials may need to be
abated, however, when damaged or as part of a larger renovation project.  Refer to the
discussion of the National Emission Standard for Hazardous Air Pollutants (NESHAP) in
the section on Regulations for further information on regulated materials.

Relatively low percentages (10 to 15 percent) of asbestos were used in floor tile and floor
tile mastic.  The dimensions of the asbestos fibers that were used in floor tiles and  mastic
are sometimes too small to  be detected with a polarized light  microscope which is the
analysis prescribed in the EPA's Asbestos Hazard  Emergency Response Act (AHERA) and
National Emissions Standard for Hazards Air Pollutants (NESHAP) regulations.  A higher
resolution  transmission electron microscope (TEM) may be needed  In  order
to detect asbestos fibers In floor tile.  Vinyl cove base and cove base mastic are a
subset of this class of materials and are also candidates for TEM analysis.

Ceiling Tile - Chrysolite and amostte were occasionally used in various types and sizes of
celling tiles.  If asbestos is present, the percentage usually ranges  from 5 to 10 percent.
Other components include mineral wool and  cellulose.  Like floor tile, ceiling tile may
contain very smal fibers which cannot  be detected with the polarized light microscope.
Often the asbestos is  restricted to a specific layer in the ceiling tile.  It Is Important to
note  that  nonasbestos celling tile may  become  contaminated If It  Is  below
friable asbestos flreprooflng.

 BUILDING SURVEY PROTOCOL AND SAMPLE ANALYSIS
 Because the project designer will need to rely on and supplement  building survey data to
 develop written design specifications, an overview of how a survey is conducted, how
 samples are analyzed, and a brief discussion of data interpretation are presented here.

 A building survey for asbestos is conducted by determining where suspect materials are
 located, quantifying materials that  appear to  be the  same  (homogeneous
 materials), collecting a statistically reliable number of  random samples for each suspect
 material identified and assessing the potential each  material has for fiber release.  This
 process has been  formalized in the regulations for schools promulgated  under the
 Asbestos Hazard Emergency Response Act (AHERA) and the subsequent EPA curriculum
 for building inspectors.

 The  AHERA method of assessment and  prioritization incorporates the factors of current
 material condition and potential for damage into a decision-tree framework. The criteria
 evaluated for each functional space such as hallways, auditoriums and classrooms include
 the extent of deterioration, physical damage, water damage, accessibility, vibration and air
 flow.  Each  suspect material  found to contain asbestos is classified into one of three
 categories: significantly damaged, damaged, or good condition.  Then, depending on the
 accessibility  factors,  the confirmed ACM is assigned  a hazard ranking number, which
 corresponds to the degree  of risk posed by the ACM including the potential for future
damage.

Samples collected for EPA  compliance purposes are analyzed  for asbestos content by
polarized light microscopy  (PLM) using  the 'Interim  Method for the Determination of

Asbestos in Bulk Insulation Samples'' found at Appendix A to Subpart F in Title 40, Code
of Federal Regulations (CFR) Pan 763.  With this method, the presence of asbestos in a
sample is determined by optical mineralogy using a light microscope with polarizing filters.
Asbestos identification is achieved  by examining the structure of the fibers and optical
properties of  the sample.  Quantification is obtained either by visual estimation  or point
counting.  Results are reported as percent asbestos by type  (e.g., chrysolite. crockJoite).
Additional information such as other fibrous components in the sample and the  nonfibrous
sample matrix may also be obtained.

EPA  standards  define  a  material that  contains  one percent or greater
asbestos, as  asbestos-containing.  The  referenced EPA method   refers to
percent  by weight.  However, the  laboratory results  are actually reported as
percent  by area.  The analyst determines  the amount of asbestos present by
an areal  visual  estimation.  If  the analysis by  the standard PLM procedure
Indicates  less than 10 percent asbestos  is present, the NESHAP regulation
requires verification  of the percent asbestos by  point counting using PLM.
Point  counting is a  more precise quantification procedure and, generally, the reported
percentage of asbestos is lower by point counting than the standard method.

As discussed earlier, the limitation  to this analytical technique  is the  resolution of the
polarized fight microscope.  Even under optimum conditions, fibers less than 0.25 nm in
diameter cannot be detected by PLM.  The size of the asbestos ffoers incorporated into
some  materials, such as floor tile, may be too small to be detected by PLM.

 OPTIONS FOR CONTROL

 Based on the  information from the building survey and laboratory analyses, a decision is
 made  on how to properly  handle asbestos-containing materials.  The options for
 controlling exposure to ACM are referred  to as response actions in the EPA AHERA
 regulations.  Response actions range from in-place management with an operations and
 maintenance (O&M) program if the material is in good enough condition, to removal if the
 material is severely damaged and cannot be repaired.  Building renovation, demolition or
 modernization  may also make ACM removal necessary.

 In-Place  Management - An operations and maintenance program is a formal set of
 standard  operating procedures to minimize asbestos exposure In the building. Two useful
 reference documents for asbestos operations and maintenance programs are the  EPA
 publication "Managing Asbestos  In Place - A  Building Owner's Guide to Operations and
 Maintenance Programs for Asbestos-Containing Materials", also known as the  "Green
 Book"; and  the National Institute of Bunding Sciences' "Guidance Manual:  Asbestos
Operations and Maintenance Work Practices".

The purpose of an operations and maintenance program is to dean up any asbestos-
containing dust or debris that may have been previously released,  maintain the ACM in
good condition, and  prevent inadvertent  disturbance to in-place  asbestos-containing
materials.  This is achieved through a series of program elements which include:

      •  Asbestos program manager appointment and training.
        Written, buHding-specific Operations and Maintenance Program,

       • Notification to building occupants, staff and outside vendors about the presence
         and tocation(s) of ACM.

       • Training staff on special work practices for handling or working around ACM,

       • Respirator, medical surveillance  and hazard communication programs,

       • Special maintenance procedures,

       • Special cleaning procedures,

       • Work order/permit system for outside vendors.

       • Periodic reinspection and recteaning,

       • Recordkeeping.

One of the measures for maintaining the material in good condition is repair which
involves limited replacement and/or patching.

Another control option, termed enclosure, involves the installation of an airtight (or nearly
airtight) barrier between the ACM and the building environment.  This measure has Bmited
applicability and is typically only used for small amounts of material on isolated columns or
beams.

 Another  option for in-place management is encapsulation of the material with a liquid
 that, after proper application, surrounds or embeds asbestos in an adhesive  matrix to
 prevent fiber release.  However, encapsulants are limited in their applicability  and may
 make eventual removal of ACM more difficult and costly.  For example, encapsulation
 should only be considered for ACM that is in good condition, not highly accessible, and
 granular or cementftjous.  If the material is not in good condition, the encapsulant may
 cause the ACM to delaminate.  Also, if fireproofing is encapsulated, the Underwriters
 Laboratory (UL) fire rating may be voided.

 Removal - If in-place management of ACM is not feasible or effective in protecting human
 health and the environment, the remaining control option is removal of the ACM. This
 option is often selected when renovation activities make it impossible to control  asbestos
 fiber release.  Partial removal of ACM in  an  area or on a floor-by-floor  basis may be
 performed in conjunction with activities such as wall relocation, sprinkler installation, and
 ceiling, light, or duct replacement From a building owner's perspective, the critical  issues
 which must be considered  in selecting any control option include the potential health  risk,
 legal liability,  regulatory  compliance,  economic factors and the  owner's long-term
 concerns.

 if the decision is made to  remove ACM, it is imperative that the project  be designed
 and  executed  properly to   protect the  safety and health  of workers and
 building  occupants,  to  avoid further  contamination  of  the building and  the
environment  and  to minimize  legal  liability.    This curriculum  provides  the
fundamental concepts which  will assist the project designer in  achieving this goal.  The
designer  must then  supplement these fundamentals  with a wide range of project

experience and continue to remain current in the various technical and  regulatory issues
associated with asbestos materials.
SUMMARY

Asbestos abatement project designers must be familiar with a wide variety of asbestos-
related issues that impact the design process. They should know that the various types of
asbestos are minerals that are in a fforous form.  The fibers are very small and can remain
airborne for several hours. The different types  of asbestos exhibit different physical
properties which may affect the design strategy. Though asbestos was incorporated into
more than 3,000 products, asbestos abatement projects typically focus on spray-applied
insulation, acoustical plaster, thermal system insulation, ceiling tile, floor tile, and floor tile
mastic.  A project designer should be able to review buBding inspection data including the
survey  protocol and the  analytical methods  used to determine  if  the information is
adequate for design specifications.  Asbestos removal is one of  a  variety of options for
asbestos hazard control.  A good written project design accompanied by careful project
management are the Keys to  successfully removing asbestos  from a  facility without
contamination to the building or the environment.

        ASBESTOS  EXPOSURE AND ITS  EFFECT ON  HEALTH

The detrimental effect on the health of people exposed to asbestos fibers has been well
documented.  Numerous studies have been conducted on laboratory animals and cell
cultures to investigate the specific  mechanism by which asbestos initiates or promotes
disease.  Similarly, studies of former asbestos mill workers and insulators have provided a
wealth of knowledge concerning the risk of disease among populations exposed to various
concentrations of airborne  asbestos fibers.  The results  of these  studies  have been
reviewed  and  analyzed by  scholars, government bodies and  research  groups in an
attempt to shed light on many of the questions that remain unanswered concerning the
health effects of asbestos exposure.

Most of the controversy  surrounding the health effects of asbestos exposure is focused on
low-level exposure to general building occupants such as school chldren and teachers.
There is little disagreement about  the detrimental effects  of occupational or high-level
exposures to asbestos fibers. To protect worker health, project designers and contractors
must focus on  methods  that reduce and control fiber levels inside the asbestos removal
area.   These engineering controls  are then augmented with protective  equipment to
minimize worker exposure to asbestos.

ASBESTOS EXPOSURE -THE ROUTE OF ENTRY

Like any hazardous  material, asbestos must first travel to the site where it can cause
disease.  The primary route of exposure for asbestos is  through the air. There have
been  reports of asbestos warts due to asbestos fibers becoming imbedded in the  skin;
however, this appears to be a rare occurrence. There is also some concern that excessive

 exposure to asbestos through ingestion, such as asbestos fibers in drinking water, may
 lead to an increased  rate of disease.  Again, however, this has not been proven to be a
 significant route of entry  leading to disease.  The greatest concern is exposure through
 Inhalation.

 THE RESPIRATORY  SYSTEM AND ITS DEFENSE MECHANISMS FOR ASBESTOS

 Since the primary route of exposure for asbestos fibers is through inhalation, it is important
 to review the respiratory system and gain a brief understanding of its defense mechanisms.
 As air is inhaled through the nose  or mouth it must  pass across membranes that are
 covered with a sticky mucous.   Very large particles of dust and fibers, which are often
 visible to the naked eye. are usually trapped at this point and are prevented from going any
 further into the respiratory system. Smaller particles will be carried further along into the
 air passageways, including the trachea, bronchi and bronchioles.

 The air passageways  have numerous turns and branches making it a turbulent trip for dust
 particles and fibers. These passageways are also lined with special cells that have hair-
 like projections into the cavities of the air passageways. These hair-like projections are
 called cilia and beat upward in a wave-like fashion.  They are also covered with a sticky
 mucous which  forms a layer across the surface of the air passageways. When particles of
dust and ffoers impact this sticky coating, they adhere and are propelled upward by the
cilia. Eventually the mucous layer with dust and ftoers imbedded in it is carried out of the
lung and into the back of the mouth where it is expelled as spft or swallowed.

The smallest dust particles and  fibers may travel through the air passageways and be
deposited into terminal air sacs called alveoli. The alveoli are depicted in Figure ///-/. The

 exchange of oxygen and carbon dioxide takes place inside the alveoli.  Oxygen from the
 inhaled breath diffuses  through the alveolar wall into a  network of capillaries.  Waste
 gases, likewise, diffuse out of the blood and into the alveolar space.  With the incoming air
 also comes dust, pollen,  and other particles such as asbestos fibers.

 When dust and asbestos fibers are deposited inside the alveoli they trigger a response.
 Large cells, called macrophages move across the surface of the air sac and engulf the
 invading parti de.  When  the partide is an organic material such as pollen, the macrophage
 effectively digests it When the partide is a mineral, such as silica (quartz) or asbestos, it
 cannot digest it.  The response often is to coat the  offending partide and effectively
 encapsulate it. Eventually, layer upon layer is built up to form scar tissue. This buildup of
 scar tissue in the lungs leads to a disease called asbestosis.

 ASBESTOSIS

 Asbestosis. or scarring of the lung was first described in England during  1907. It was the
 first disease recognized as linked to asbestos fiber exposure.  The alveolar wall thickening
 reduces the ability of the  lung to expand and contract normally. This results in a retracted
 or restricted lung with an inability to exchange oxygen and, to a lesser extent carbon
 dioxide in a normal manner.

The buildup of scar tissue in the lung occurs gradually over many years.  A worker
exposed to high concentrations of asbestos may not experience any overt symptoms for 10
to 30 years after the start of his or her exposure. The symptoms will gradually appear and
increase in severity.  These symptoms include shortness of breath, easy fatigue, mild

-------

cough and weight loss.  Advanced  cases will  usually include obvious cyanosis, a blue
coloring of the mucous membranes visible in the mouth caused by the lack of oxygen.

These symptoms will continue despite the cessation of exposure and death may occur as a
result of infection such as pneumonia or influenza.

The increased scarring reduces the elasticity of the lung.  This makes it more difficult for the
heart to pump blood through the vessels in the lung. The added stress can  result in an
enlarged heart and in some cases may lead to a heart attack.

Annual medical examinations of workers exposed to asbestos fibers  are often conducted
to detect asbestosis. The physician will elicit a history of symptoms from the patient and a
documented  history of past asbestos exposure. The patient with clinical asbestosis will
exhibit crackling respiratory rales in the lower chest fields upon chest examination. A chest
X-ray will usually demonstrate  Interstitial  fibrosis. pleura!  plaques, or significant pleura I
thickening.  Interstitial  fibrosis,  or lung scarring, will appear as opacities predominantly in
the lower lobes of the lung. Pleural plaques are localized areas of fibrous thickening in the
chest cavity lining known as the pleura. Pleural  thickening  Is a diffuse fibrosis of the chest
cavity lining.The results of pulmonary function studies may show a restrictive defect  Other
indications include reduced blood oxygen and an abnormal diffusion study.  The definitive
diagnosis for asbestosis  is the  open lung biopsy, although this is an invasive procedure
and is  usually neither necessary nor desirable.

Patients  with clinical asbestosis should be immediately removed from any additional
exposure to airborne mineral dusts, including  asbestos.   Physicians may advise  their
patients to take specific steps to help prevent lung infections, to have annual X-rays to

 detect possible lung cancer early, and not to smoke cigarettes.  Unfortunately, once the
 fibrosis has occurred, the scarring cannot be reduced or removed.
 Asbestosls should only be a problem for asbestos abatement workers who fail to follow
 proper work practices and fail to wear their personal protective equipment including
 respirators.  It is incumbent upon the asbestos abatement designer to require that stringent
 respiratory protection measures be implemented on their projects.

 LUNG CANCER

 Lung cancer is the most common of the serious health effects associated with airborne
 asbestos fiber exposure.  It has been associated with asbestos exposure since the 1930s
 and is responsible for about 20 percent of the deaths of insulation workers who installed
 asbestos-containing materials in buildings.  Like  asbestosls. it appears that a  dose-
 response  relationship exists between asbestos exposure and lung cancer.  That is. the
 greater the total exposure to asbestos fibers, the greater the risk of developing lung cancer.
 The latency  period, however, is generally much longer for lung cancer.  From the time of
 first exposure to the onset of disease is often 20 to 40 years.

 The relationship among asbestos exposure, cigarette smoking, and lung cancer has been
 well documented.  Workers exposed to asbestos who  do not smoke cigarettes are about
 five times more  likely to develop  lung cancer than their nonsmoking,  nonexposed
 counterparts. Workers who smoke cigarettes and are not exposed to asbestos are about
ten times more likely to contract lung cancer than people who do not smoke and are not
exposed to  asbestos.  However, workers who smoke cigarettes and are exposed to
asbestos are over 50 times more likely to get lung cancer than nonsmoking, nonexposed

workers.   The  relationship between smoking and asbestos exposure is  called a
synerglstlc effect since exposure to both greatly increases the risk of disease.  While
these statistics are based on the cancer incidence  among asbestos  insulation workers
many years ago, they reinforce the need to follow proper work practices to reduce worker
exposure during abatement projects.

Another purpose of the annual medical examination  among asbestos abatement workers
is the early detection of lung cancer.  Among the general population, about 75 percent of
the lung cancers are first discovered too late for successful treatment  However, In about
25 percent of the cases  surgical treatment is  possfcte.  Of these individuals, 40 to 50
percent are deemed •successful' with survival in excess of five years. For this reason, the
physician wiB usually order annual chest X-rays for older asbestos workers and may also
recommend additional tests for any asbestos worker who smokes cigarettes.

If lung cancer is detected, the most frequent therapy is surgery, if possible.  This may be
followed by cobalt radiation treatments.  In rare cases, chemotherapy is employed.  In ail
cases, follow-up medical surveillance is required.

MESOTHELIOMA

Mesothelioma is a very rare form of malignant cancer involving the membrane-like linings
of one or more body cavities.  If it occurs in the  lung cavity it is called mesothelioma of the
pleura. In the gut cavity it is termed mesothelioma of  the peritoneum. In rare cases it may
occur in the heart cavity, which is termed pericardia! mesothelioma. The mesothelial lining
of the lung is a very thin transparent membrane that lines the chest wall, doubles back
upon itself, and lines the exterior of the lung proper.  The lining of the chest wan is called

 the parietal pleura; the lining of the exterior lung surface is called the visceral pleura.
 These mesothelial linings are depicted on Figure 111-1.

 The relationship between mesothelioma and asbestos exposure became well known in
 the early 1960s. At that time the scientific community thought that any mesothelioma must
 be caused by asbestos exposure.  Today, it is recognized that  some other chemical or
 physical agents such as ethylene oxide and erionite may also cause mesothelioma.  The
 vast majority of cases, however, appear to be linked to asbestos exposure.

 Similarly to asbestosis and lung cancer, the latency period for mesothelioma is frequently
 30 to 40 years after the first exposure to asbestos. There are, however, many documented
 cases of  mesothelioma occurring with a shorter  or  longer  latency period.  Unlike
 asbestosis and lung cancer, there does not appear  to  be  a clear dose-response
 relationship between asbestos exposure  and the onset of mesothelioma.  Cigarette
 smoking does  not appear to have any additive or synergistic effect on the incidence of this
 disease among persons exposed to asbestos.  Exactly  how asbestos fibers are able to
 initiate mesothelioma in the pleura! cavity or the peritonium remains a mystery.

 Annual medical examinations  of  asbestos workers allow the physician to  detect a
 mesothelioma at  an early  stage of development.  Various therapies have been tried.
 including chemotherapy, radiation and  surgery, without success.  The  mesothelioma
 usually proves fatal within a year of diagnosis. A worker with pleura! mesothelioma will
 usually experience a sharp pain in one side of the chest, cough,  may be short of breath,
and often exhibits a loss of weight. Persons with mesothelioma of the peritoneum  will
usually have abdominal swelling, a cramping pain, and weight loss.

OTHER DISEASES AND CONDITIONS ASSOCIATED WITH ASBESTOS EXPOSURE

MesothePoma. lung cancer and asbestosis are the three diseases most often associated
with asbestos exposure. Several other diseases and conditions are also more prevalent
among persons exposed to asbestos fibers.  These include pleural  plaques, pleural
thickening,  pleural  effusion,   kidney  cancer,  and  cancers   of   the
gastrointestinal tract.  The increased incidence of malignancies in the gastrointestinal
tract and kidneys lends some credence  to the theory that asbestos  exposure through
ingestion may be more serious than previously recognized.  Others  in the scientific
community think these increased rates of malignancies may be due to the translation of
asbestos fibers from the lung to other areas of the body.  The  exact cause again remains
unknown.

Pleural plaques are fibrous lesions that appear on the surface of the parietal pleura. They
are usually thin, about one-half to one inch wide, and one  to two  inches long.  They may
also be calcified, especially among older asbestos workers with a long history of exposure.
The pleural plaques usually first appear about 10 years after first exposure and continue to
enlarge  and  become more frequent over the next 20 to  50 years. A person with pleural
plaques usually experiences no discomfort or other symptoms associated with these
lesions.  They can be detected on chest X-rays and often serve as a marker for previous
asbestos exposure.  For this reason the physician may conduct additional tests designed
for the early detection of asbestosis and lung cancer.

Pleural effusion and pleural  thickening often occur among workers exposed to asbestos.
Pleural effusion is the accumulation of fluid in the pleural cavity which may or may not be
associated with a sharp chest pain during  coughing, sneezing, or deep  breathing.  Pleural

 have indicated that there is a dear relationship between the duration and magnitude of
 asbestos exposure and the occurrence of pleura!  effusion.  The magnitude of the dose
 does not appear as important a factor with pleura! thickening, but there does  exist a dear
 relationship between the  time since first exposure to asbestos and the occurrence and
 severity  of pleura! thickening.  In severe cases of pleura! thickening the asbestos worker
 will  have a reduced lung function or capacity and usually an elevated blood  carbon
 dioxide level.

 Treatment of patients with pleura! effusions is usually limited to rest and administration of
 pain killers until  the irritation  subsides.   The  fluid  may be  drained in very rare
 circumstances.   Only in  very rare  cases are patients suffering from severe pleura!
 thickening recommended for surgery to remove sections of the thickened pleura.  In most
 instances, patients are advised to live with the discomfort rather than  undertake a serious
 surgical procedure.

The  relationship between increased incidence of malignancies of the gastrointestinal tract
and  kidney and asbestos exposure is less clear, and pales in significance when  compared
to the increased incidence  of  lung cancer and  mesothelioma which results among
asbestos-exposed  workers.   From the  standpoint of  designing  asbestos abatement
projects,  it is reasonable to conclude that if sufficient protective measures are taken to
prevent or minimize the occurrence of asbestosis, lung  cancer and mesothelioma, then
adequate protection will be afforded for malignancies of the gastrointestinal  tract  and
kidneys.

RECOGNITION OF CONTROVERSIAL ISSUES

To this day many controversial issues remain surrounding the effects on health posed by
exposure to asbestos fibers.  These issues include the level of exposure capable of
causing  disease; the type and size of asbestos fiber that may be responsible for
disease;  and  various  theories describing how the  disease processes occur.
Disagreements on many of these issues exist even  among the most knowledgeable
scholars on the subject  It is important to recognize these controversies, but not necessary
to delve Into them in great depth in this course of instruction. It is equally important to
recognize that many of  the issues  are  academic as far as asbestos abatement project
designers are concerned due to the realities of such  projects, magnitude of asbestos
exposure, and current regulations.

One current topic of debate concerns the level of airborne asbestos exposure responsible
for  an increased incidence  of  disease.  The  controversy centers around exposures
experienced by routine  building occupants in facilities with friable asbestos-containing
materials.  Additionally,  there is significant debate over the magnitude and duration of
exposure experienced by custodial and maintenance workers in similar buildings. To fully
comprehend these debates one must understand all of the different diseases and have a
firm grasp of the scientific and medical literature which serves as the basis for the debates.
However, when designing  the asbestos abatement project, primary concern  is  the
protection of asbestos abatement workers and others in the vidnlty of the project. There is
little debate that possible exposures when performing an asbestos abatement project such
as removal of friable  pipe insulation can be  very  high and  consistent with past
occupational exposures of workers who installed these  same products.  Accordingly, the

                                             S#c*oo II - Artwka Exposure and tt» Effect on
 question of low-level exposure becomes a moot point for most asbestos abatement
 projects.

 A second major controversial topic centers about the mineralogic types of asbestos and
 their respective ability to cause disease. Again it is imperative that each type of disease
 and condition (e.g., lung cancer, mesothelioma, pleura! plaques) be considered in the
 context of each different type of asbestos (e.g., chrysotile, crocidoite).  For example, it may
 be that chrysotile Is less potent when compared to croctdolfte in causing mesothelioma. but
 may be  an equally or more potent source of fibrosls.  Again, from a  health-effects
 standpoint to the asbestos abatement project designer the issue is not a major one.  The
 current USEPA, OSHA and state regulations do not distinguish between asbestos fiber
 types.   Accordingly, regulations and  guidelines affecting worker protection,  most
 abatement practices, transport of waste generated, and waste disposal are the same for all
 types of asbestos.

 The third controversial issue mentioned here has to do with how asbestos fibers cause
 disease.  Some researchers support the view that long thin fibers are the most hazardous;
 others point out that short thick fibers may be equally as potent; and yet others profess that
 the size  may not be an important factor. Again, the controversies become easier to
 understand when each disease is considered separately rather than broad sweeping
 generalizations.  To overcome this dilemma, the asbestos abatement designer must rely
 on common sense.  Asbestos  workers who installed asbestos-containing materials in
buildings were  exposed to asbestos-containing dust and many developed asbestos-
related diseases.  The abatement of these  same asbestos-containing materials  from
buildings, if performed without proper protective measures,  would surely result in

exposures to asbestos-containing dust and workers would develop asbestos-related
diseases.

It is the purpose of this course to provide a brief understanding of the work practices and
procedures which will minimize asbestos exposure to asbestos  abatement workers and
others in the vicinity of asbestos abatement projects.

SUMMARY

Asbestos abatement project designers should recognize that asbestos is primarily an
inhalation exposure  concern.  When performing an asbestos abatement project the
exposures to airborne asbestos fibers may  be similar to that experienced by asbestos miP
workers  and insulation installers  in the  past.  It  is the designer's and contractor's
responsibility to minimize worker exposure through  proper design and execution of the
remove!  project. The three major diseases  associated with  asbestos exposure are
asbestosis. lung cancer and mesothelioma. All  of  these diseases take many years  to
manifest themselves, often  exceeding 30 or more  years.   Each of these diseases  is
debilitating, with lung  cancer often fatal, and mesothelioma always fatal.   Cigarette
smokers who are also exposed to asbestos are at a much greater risk of developing lung
cancer.  Other  diseases and conditions  that may occur among workers exposed  to
asbestos Include pleura! effusion and thickening, and malignancies of the gastrointestinal
tract and kidneys. Annual medical monitoring for asbestos abatement workers is required
in order to detect these diseases at an early stage.  If detected  early, treatment is often
effective for all diseases except mesothelioma. A properly conducted asbestos abatement
project should not put workers or others in the vicinity  of the project at a significantly
increased risk of developing these diseases.

      OVERVIEW OF  CONDUCTING  AN ABATEMENT PROJECT
                AND ROLES OF VARIOUS DISCIPLINES

INTRODUCTION

This section provides an overview of the sequence of steps involved in an asbestos
abatement project from the planning stages through reoccupancy of the building space.
This information will serve as a framework for the more detailed discussions on specific
design elements in subsequent sections.

In the course cf deve'oping and implementing asbestos abatement specifications and
drawings, the designer may interface with a variety of disciplines. The building owner or
local education agency (LEA) may call upon the designer to assist in the selection of some
members of the abatement project team, such as  the contractor or air monitoring firm. A
brief discussion of the responsibilities and qualifications of these  various disciplines is
presented here so the project designer will understand their respective roles in executing a
successful abatement project.

ROLE OF VARIOUS DISCIPLINES

Once a decision has been made to conduct an asbestos abatement project, the next step
is to assemble  an abatement project team.  Some of the team members may serve in
an advisory capacity and some will have an active role. The team is multldlsclplinary
and, depending on the size and scope of the project, may include a project coordinator,
project designer, architect/engineer, industrial hygienist, safety professional, project
monitor, legal  counsel, an analytical laboratory, medical clinic,  contractor(s), and a

 transportation and disposal firm.  The size of the project team is related to the scope and
 complexity of the abatement project Not all of the various disciplines are needed on every
 project and some individuals or firms may  serve  multiple roles.   Through the project
 specifications, the project designer plays a  large role in  coordinating and defining the
 functions of other parties.

 Project Designer

 The project  designer often has  previous  training and experience  in architecture.
 engineering,  industrial hygiene, or construction management.  The project designer
 develops the  specifications for contracts and  provides working drawings and may specify
 reinsulation or replacement materials. The project designer may also be retained to assist
 In bid solicitation and contractor selection  and to assume day-to-day project management
 responsibilities.

 It is imperative that a project designer involved in asbestos abatement projects receive
 asbestos-related training and accumulate a wide diversity of  asbestos project design
 experience.  EPA regulations  now require project designers  to  be accredited
through  an  EPA-approved  training  course  In order  to  perform asbestos
 related design  work in public and commercial buildings as  well  as schools.
The designer must thoroughly understand all applicable regulations, safety procedures,
and state-of-the-art work practices and techniques that can be  applied to  an abatement
project

 Industrial HvQienist

 The industrial hygienist helps establish procedures for minimizing exposure to asbestos,
 trains workers, selects protective equipment, conducts air monitoring before, during and
 after the project, and addresses additional industrial hygiene concerns such as heat stress
 and  other  potentially toxic  materials  being  used on  the project  (solvents,  paints,
 encapsulants.  etc).  As with the architect/engineer, it is important that the industrial
 hygienist has specific asbestos-related training and project experience.

 Safety Professional

 An asbestos abatement project has all the safety hazards inherent to construction work
 plus the added facet of handling a toxic material.  A safety professional may be included on
 the project team of large or complex projects to address hazards unique to the project such
 as unusual  scaffolding requirements, work in confined spaces, fire safety, or energized
 electrical lines.  The contractor should also have safety expertise within his own staff to
 address routine safety  concerns as well as any that arise during the removal project.

 Project Monitor/Clerk of the Works

The project  monitor is  retained by the building owner or LEA and remains on site for the
duration  of  the project to ensure that work is being performed in accordance with the
written project specifications.  Some state regulations now require project monitors for
asbestos removal  projects.   The  project monitor is  responsible  for  extensive
documentation  and maintaining a  dally  log which  includes a quality  assurance
checklist for  contractor work procedures, a record  of site activity, dafly air monitoring results

and other project-related records.  Project monitors  also  conduct formal  approval
inspections at certain critical stages of abatement projects. The project monitor may collect
afr samples (if qualified) or this may be assigned to an independent testing firm.

The project monitor should have an in-depth understanding of proper work procedures,
safety practices  and  protective equipment,  as  well  as construction management
techniques.  Additional training in collection  and analysis  of air samples is  also  a
prerequisite if the  project monitor is performing this function.   The project designer must
ensure the project specifications dearly define the  authority and functions of the  project
monitor and independent testing firm if they are not the same entity.

Leaal Counsel

The legal counsel provides  necessary  legal advice concerning contracts, insurance,
statutory law, potential  liability and  documentation.  While it is ultimately the designer's
responsibility to ensure  that the  specifications comply with regulations, there is an added
advantage in retaining legal counsel that is versed  in asbestos-related issues and local,
state and federal statutes.

Analytical Laboratory

Laboratory analytical  results  provide information  about airborne fiber levels in the work
area and outside the work area both during and after abatement is completed. They are
used to make key  decisions about worker respiratory protection, the  safety of occupants,
and release of a work  area for reoccupancy.

 The two most common techniques used for analyzing air samples are phase contrast
 microscopy (PCM) and transmission electron microscopy (TEH). These methods
 are described in the section on air sampling requirements.  A person who performs PCM
 analyses on personal air  samples collected for compliance with  the Occupational
 Safety and Health  Administration (OSHA)  asbestos standard  must attend the
 National Institute of Occupational  Safety  and Health (NIOSH) 582  course (or an
 equivalent) for sampling and evaluating airborne ftoers. (This course is recommended for
 all PCM analysts.)  Laboratories  that  perform TEM analysis for clearance samples on
 school abatement projects are required to participate in the National Voluntary  Lab
 Accreditation  Program  (NVLAP) administered by  the National  Institute of
 Standards  and Technology (NIST).

 In addition to these requirements, NIOSH and  the American  Industrial  Hygiene
 Association (AIHA)  sponsor a voluntary  assurance/quality  control program for
 laboratories that perform PCM analysis.  It  is called the Professional  Analytical
 Testing (PAT) Program. A similar program for individual analysts, called the Asbestos
 Analyst Registry, is sponsored by AIHA. While participation in these programs does not
 assure competency and does not  mean the laboratory has  AIHA accreditation, it can be
 used, along with other criteria such as experience and laboratory management practice, to
 select a good laboratory.

 Medical Clinics

Workers  and other personnel  who enter asbestos abatement projects are  required to
undergo annual medical monitoring in accordance with the OSHA asbestos standard.  The
cost  of the  medical examination is bome by the employer. A physician  conducts  this

medical screening and determines the capability of the individual to wear a respirator.
Most occupational health clinics and many family practices are capable of conducting the
necessary medical procedures.

Contractor

The contractor not only does the work, but can be a valuable resource to the designer on
removal and disposal techniques and logistics for performing the asbestos  removal work.
Some  asbestos contractors are qualified to install replacement materials while others
subcontract the work.  Contractors and supervisors who perform abatement in schools are
required to  be  accredited through  an EPA-approved course for abatement  project
supervisors and contractors.  Asbestos abatement workers must be accredited through an
EPA-approved course for workers.

An amendment  to the Asbestos School  Hazard  Abatement  Reauthortzatlon Act
(ASMARA)  mandates this same accreditation for  contractors and abatement workers
performing asbestos abatement projects In public and commercial buildings.  There often
are  additional  local  and  state licensing requirements.   In  addition  to  the statutory
prerequisites, other important qualifications for contractors include experience, amount of
equipment and other resources, effective medical  monitoring and respiratory protection
programs, and quality control procedures.  Establishing the qualifications/credentials of the
contractor is critical because the capabilities of the removal company are a key factor in the
success of the project.

 Transportation and Disposal Firm

 The project designer must clearly  understand  all  local, state and federal  regulations
 concerning waste packaging.  In some municipalities and states the asbestos waste must
 be transported to the approved disposal site by a licensed waste transporter who is
 independent of the asbestos abatement contractor. In this case, the waste transporter must
 be retained by the building owner.  In some cases,  the transporter may be restricted by
 regulations or may not want the responsibility of  unloading the waste at the disposal site.
 Then, the asbestos removal contractor would need to coordinate with the transporter and
 perform this function.

 SEQUENTIAL CONSIDERATIONS  FOR CONDUCTING AN ASBESTOS REMOVAL
 PROJECT

 Although each abatement project is different and must be addressed  individually, there are
 some fundamental concepts that can be applied to most abatement work.  The steps
 involved in conducting an asbestos abatement project are organized into several broad
 categories as depicted in Figure IV- 1.

 Development of Contract Documents
The  technical specifications, drawings, and other documents such as those outlining
general and special conditions are collectively referred to as contract documents. They
are used by contractors to develop a bid and perform the work.  They are a legal
agreement  between the owner and  contractor  and define the role of all parties.  The
contract documents also serve as a permanent record of the work performed.

 Development of the contract documents begins with understanding the building owner's
 objectives, what materials the building owner wants removed, reviewing existing drawings.
 and reviewing the asbestos survey report. The designer supplements this information with
 a site visit and  fact-finding mission.  The extent of the follow-up investigation that the
 designer needs to do will depend on the scope and detail of the original inspection.  For
 example, a  school  inspecton conducted in accordance with AHERA  protocol would
 probably be more detailed than an asbestos inspection conducted as part of a preliminary
 environmental assessment for a commercial property.

 There  are  many  building-related  Issues  which  are critical  to the project
 designer that  are  not typically Included  In an asbestos Inspection report.
 These  items,  such  as contractor access, availability  of  power  and  water,  fire
 protection/emergency exits, etc., are discussed in more detail in the design lab portion of
 this course.  Once the designer has  a dear understanding of the scope of work, the types
 and  locations of asbestos-containing material to be removed, and the site conditions that
 will impact the performance of the work, the abatement design can be developed and put
 into written form.

 Selection of Team and Project Startup Activities

 Proper planning is critical to the success of an asbestos removal project. Before any work
begins, the team members must be selected, workers must be trained, authorities notified,
permits obtained,  equipment and supplies  procured,  and the laboratory and landfill
selected.  The project designer is typically involved in assisting the building owner with the
selection of other team members such as the contractor and project monitor.

Pro-Bid Meeting - A  pre-bid meeting  and walk-through of the project  area with  the
contractor, consultants, and building owner's representative is very useful for  identifying
areas that need special attention, resolving Issues associated wtth work area isolation,  and
documenting preexisting conditions of the work.  Other issues which can be addressed at
this time include security of the area, parking and equipment storage, special tools and
equipment, air monitoring,  time constraints, special safety concerns, inadequate written
specifications and any other  unique issues associated with the project  The pre-bid
proceedings should be documented in written form and made a part of the bid documents.

Selection of Contractor(s) - The  project designer reviews bid submittals and,  in
conjunction with the bulking owner, selects the contractor to perform the work.

Pro-Job Meeting - The pre-job meeting is a foRow up to the pre-bid meeting to resolve any
remaining issues regarding  scheduling, access, security,  etc.

Notification - If the removal  involves more than 160 square feet, 260 linear feet, or 35 cubic
feet of regulated asbestos material or if  a building is being demolished, the EPA requires
notification of their NESHAP office at least 10 days before the project begins.  This is
generally considered to be  a dual responsibility of the building owner and the contractor.
More information about regulated materials and notification requirements is provided in the
section on Regulations.   There may be  additional  or more  stringent state or  local
requirements for notification, disposal permits,  building permits, required training and
licensing. For example, some states require notification of the appropriate agency  if any
asbestos materials are removed, regardless of the amounts.

 Documentation - The planning stage is also the time to establish a recordkeeping system
 for the project. The project designer should coordinate with the  project coordinator and
 legal counsel to specify items that the contractor needs to provide for the building owner's
 files such as the notifications, waste disposal documentation, training  records, proof of
 medical exams, daily air monitoring results,  etc.  The project monitor should also be
 required to retain documentation regarding contractor work procedures, safety procedures,
 daily activities and final air clearance samples  on the site.  This documentation is typically
 kept in a project log book which becomes part of the building owner's files at the end of the
 project

 Worker Protection

 The abatement contractor must  devote a  significant amount of  time and resources to
 worker protection issues before work begins.  The written  design   specifications
 should require the contractor to provide documentation of these activities.

 Respiratory  Protection  - It is an OSHA requirement that each worker is at all times
 provided with proper respiratory protection and  training on  its use, maintenance and
 limitations as well  as training on work practices.  The respirators provided must  be
 approved by  National Institute for Occupational Safety and Health (NIOSH) and the Mine
 Safety and Health Administration (MSHA) for protection in  atmospheres containing
 asbestos.  More information  about  respirator selection is provided in  the  section on
 Respiratory Protection and Protective Clothing.

The project designer may  need to consult with the industrial  hygienist to establish
appropriate levels of respiratory protection for various phases of the project  ft is generally

pressure-demand or continuous-flow, supplied-air respirators during the demolition  or
removal of asbestos.  When air-supplied respirators are used, the air must be cleaned of
any impurities to meet the requirements of Grade D breathing air. Ensuring that workers
receive quality breathing air is a major consideration for an asbestos abatement contractor.

Protective Clothing - OSHA requires that full-body protective clothing be worn  by those
who enter the work area.  Generally, disposable coveralls are used to drcumvent the
special handh'ng procedures that would be required for laundering contaminated clothing.
Some  contractors, however, elect to set up the necessary equipment for washing and
reusing protective clothing. The primary purpose of protective clothing is to keep gross
contamination off the body. The proper use of protective do thing, coupled with proper
decontamination procedures, including  thorough showering of the head  and body,
minimizes the chance that asbestos will  be transported out of the work area. Other
protective equipment may also be necessary to accommodate specific safety  hazards,
such as hard hats, and steel-toed boots.

Medical Examination - Every worker and anyone else entering a contained work area
once removal begins will need  to have a medical examination.   This  examination  is
specified by OSHA and includes a medical history, physical examination and pulmonary
function procedures.  Chest X-rays are taken at the discretion of  the physician. The
physician must also determine if the individual is physically fit to wear a respirator.  During
the examination, the physician is required to explain to the patient the multiplied risk  of
contracting King cancer which results from exposure to asbestos and smoking cigarettes.

 Training - Workers and supervisors must receive appropriate training before performing
 asbestos removal work.  If trie abatement project is being conducted in a school facility
 (kindergarten through 12th grade), the contractor and workers must be trained in
 accordance  with  the  accreditation requirements outlined  in the  Asbestos  Hazard
 Emergency  Response Act  (AHERA).  The Asbestos School Hazard  Abatement
 Reauthorization Act (ASMARA) requirements make this training also mandatory for
 asbestos abatement projects performed in  public and  commercial  buildings.   These
 include a mandatory training course for workers and supervisors. These courses must be
 conducted by training providers  that are accredited  by the EPA or a state  agency
 counterpart

 For aU projects, the OSHA training requirements outlined in the asbestos standard (29 CFR
 1926.58) apply. These requirements do not specify a number of hours but require certain
 topics to be included in the instruction to workers. OSHA requires the contractor to assign
 a competent person,  usually a foreman who has received a four- or Five-day  training
 course, to each abatement project.  In addition to  the  EPA and OSHA requirements
 discussed above, the training requirements of the OSHA Hazard Communication Standard
 are also  applicable  to  personnel on  almost all asbestos removal projects. Many states
 also have training requirements which meet or exceed those imposed by federal statutes.

 Air Sampling - The contractor is required by the OSHA asbestos standard to conduct
 personal monitoring to determine worker exposure to airborne ffoer levels.  The air
sampling data is used  to determine the appropriate  level of respiratory protection  that
should be worn, and to document that fiber levels are being effectively controlled.

 Section (V - Owvww ot A»t»rto« Removal
STUDENT UM*JAL
Containment of the Work Area

Decontamination Unit - The first task is to construct a decontamination unit at an entrance
to the work area. The  decontamination unit typically consists of a dean room, a shower,
and an equipment room (contaminated) with an air lock constructed between each room.
The air locks serve to minimize the flow of asbestos-containing dust out of the work area.
Curtained doorways  made from  polyethylene sheets are typically used to  separate the
rooms and form air locks.

Waste Load-Out Area  - A waste load-out area is often constructed adjacent to another
work area entrance or trie decontamination unit. It usually consists of a single storage area
for drums or bags and is joined to the work area with an  air lock.  Drums are cleaned
before transferring them to this chamber from the work  area.   When a  load has
accumulated, this room is sealed from the work area and then sealed to  an enclosed truck
on the other side. The bags or drums are then placed in the truck for transport to the
landfill.   While the truck is being loaded and unloaded, an EPA warning sign must be
placed on the outside of the truck.
Sealing Off the Area - Before any removal work begins, the work area must be sealed off
from all other areas to prevent migration of asbestos fibers. After shutting and sealing off
the air handing system, movable items are cleaned using appropriate procedures and
moved outside the work area All surfaces, with the exception of those covered with ACM.
are pre-deaned using wet wiping techniques and/or high efficiency paniculate air (HEPA)
vacuums. All openings to the work area including ducts,  doorways, windows, etc. are
sealed using polyethylene sheeting and tape. Items that cannot be removed from the work
area are covered in  place. All power inside the work area must be shut off and locked out

 and then temporary lighting  is set up.  Floors and walls are  covered with at least two
 protective layers of polyethylene sheeting secured with tape.  These  procedures are
 discussed in detail in the section on Considerations In Designing Engineering Controls.

 Establish Air Pressure Differential - Once the area is sealed off. air filtration units equipped
 with HEPA filters are positioned to maximize the air movement in the work area. When the
 air filtration units are operating, the work area is under negative pressure with respect to
 the surrounding air.  With negative air pressure established,  air will leak  into rather than
 out of the work area if a barrier is torn.  All entrances to the  work area are secured to
 prevent inadvertent entry, but to allow for emergency exit   All entrances and exits are
 posted with the required OSHA danger sign (see Figure V-f in next section).

 Removal

 Before entering a contained work area, workers remove their street clothes  In the dean
 room of  the decontamination unit and don fun-body protective dothing and respirators.
 They then pass through the shower area and equipment room  into the work area.

 Wet Removal and Continuous Cleanup - Typically teams of workers are used to remove
 spray-applied fireproofing or acoustical ACM. Some of the workers will scrape and brush
 material from the substrate while others keep the material wet  and. as K is removed, place
 it in  impermeable bags for disposal.  A wetting agent is added to the water for better
penetration of the material being removed.

Air Sampling  - During removal, personal air samples are collected to determine workers'
exposure inside  the containment area.  Personal air monitoring is the contractor's

regulatory responsibility.  Additionally, area air sampling is conducted each day outside
the work area as a check for fiber leakage out of the work area.  This sampling is not
required by law, but  is often conducted by a representative  of the building owner to
document effective containment ideally, sample results are available by the next day to
help determine if proper respiratory protection is being worn and if engineering controls
are effective.

Waste Disposal - The asbestos waste is typically double bagged or placed into fiber
drums and moved into the load-out area where  it is  held  until enough containers have
been accumulated for a trip to the landfill.  Waste is then transported to the landfill in an
enclosed truck. Workers who load and unload the truck should be wearing respirators and
protective clothing.

Detailed Cleaning - After the gross material has been scraped from the substrate,  the
remaining residue is removed with  a nylon bristle brush, scrub pads or an equivalent
abrasive material. Then the surface is wet cleaned to remove all remaining vtetoJe residue.

Final Cleanup

HEPA Vacuums and Wet Wiping - Once the removal is complete, the remainder of the
work area and all equipment are thoroughly cleaned using HEPA vacuums and wet wiping
techniques.  Next the  outer layer of polyethylene is removed from the floors and walls.  At
this point the sequencing of other clean-up activities and installing any replacement
materials may vary.

 Visual Inspection of Substrate - The building owner's representative, who  may be  the
 project designer, industrial hygienist. or project monitor, generally performs an initial visual
 inspection of the substrate to ensure that all visbie residue has been removed.  A team
 approach to the inspection, which  includes a representative of the contractor and building
 owner, is the most effective way to find and resolve problems.

 Lockdown - If the substrate has been properly cleaned, the contractor receives approval to
 apply a water-based sealant to the surfaces where the asbestos has been removed.  This
 serves to lock down any remaining fibers that could not be seen.

 After the sealant has dried, the remaining layers of polyethylene are removed, leaving only
 the  critical barriers on the vents, doors and windows in place.   The contractor then
 performs additional wet wiping of all surfaces in preparation for final clearance air testing.

 Visual Inspection of Project Area - Once the contractor indicates the area is ready,  the
 building owner's representative performs a visual inspection of all surfaces in the work
 area.  If no visible  contamination is detected, final clearance testing is conducted using
 aggressive sampling techniques.

 Aggressive Air Sampling - The purpose of aggressive sampling is to create activity in  the
work area that would suspend any remaining fibers into the air. Once surfaces in the work
 area are thoroughly dry. the air testing firm directs the exhaust of leaf blowers  at all
surfaces, and then operates circulating fans and the air filtration units wh8e air  samples are
collected.

The air samples are routinely analyzed by transmission electron microscopy (TEM) to
determine the airborne fiber concentrations in the work area. The AH ERA regulation for
schools require this type of clearance testing.  Airborne fiber levels must be below 70
asbestos structures per square millimeter of filter area (typically equivalent to 0.01 to 0.02
structures per cubic centimeter of air) or statistically less than the concentrations  in the
outside make-up air that  is coming into the work area, tf the airborne fiber concentrations

a retest Is conducted. More information is provided about clearance testing and alternative
clearance procedures for industrial and demolition projects in the section on Air Sampling
Requirements, Protocols  and Data Interpretation.

Protect Completion

Reuse of Space - After the area has met the final clearance criteria, replacement material
can be installed and other trades people can  enter the area to conduct further renovation
activities.  Typically a final walk-through is  conducted by  the  contractor and building
owner's representative to document the condition of the project area and  resolve any
punch 1st Hems before the contractor releases the space. A  punch list is a compilation of
work by the contractor which needs to be completed to achieve compliance with the written
specifications. In closing  out the project, it is critical that the building owner secures all the
required project documentation from the contractor and the project monitor.

Removal of Thermal System Insulation

The  methods for  removing thermal system insulation are basically the same as for
surfacing materials.  The material is removed in blocks or sections, depending on how it

 was applied, and remaining material is scraped off the substrate.  For certain pipe lagging,
 a gtovebag may also be appropriate.   This technique allows asbestos-containing pipe
 insulation to be removed in a small enclosure with attached gloves that has been sealed
 around the pipe. It is a two-person operation with one worker removing the lagging and
 the other wetting the material  with a sprayer inserted into the bag.  Workers wear protective
 equipment and unauthorized personnel are prohibited from entering the area where
 removal is taking place.

 SUMMARY

 The asbestos abatement project designer may need to rely on the expertise  of a variety of
 disciplines to enhance the design and implementation of a  removal project.  A brief
 summary of these disciplines has been  provided in this section to familiarize the project
 designer with their various capabilities.

 A large  portion  of a project designer's responstoilrty involves proper planning and
 sequencing of asbestos removal activities. The written project specifications prepared by
 the project designer fully define  the scope and the requirements of the project.  The
 technical portion of  abatement specifications typically addresses project tasks in the
 following sequence: planning, worker protection, containment of work area, removal, final
 cleanup and project completion.  The technical aspects of worker protection, work area
 containment, removal and final  clearance are presented in  greater detail  in the following

   CONSIDERATIONS  IN  DESIGNING  ENGINEERING CONTROLS

INTRODUCTION

As discussed In  Section IV, an asbestos  removal project consists of several phases.
Phases which are directly  involved with  the  actual removal of the  material  include
containment  of the  work  area,  removal,  final cleanup and disposal.  This
section discusses the equipment, methods and procedures  used to minimize the
generation and migration of airborne fibers during these phases of the removal effort.
Collectively these measures are termed engineering controls.  Where appropriate, this
section also highlights elements  In the design specifications as they relate to the
engineering controls used in  each phase.

Typical engineering controls for asbestos removal projects include construction of  a
temporary barrier to confine fibers to the work area, establishing negative pressure inside
the work area with high-efficiency participate air (HEPA) filtration units, and wetting the
asbestos-containing material  (ACM) with amended water before, during and after removal.
Regardless of whether the design is a means and method specification, a performance
specification or a hybrid of the two,  the project designer must have a dear understanding
of these various engineering controls and how they can be modified to accommodate site-
spedfic conditions.

                                                                              Pag* 2

 CONTAINMENT OF THE WORK AREA
 Construction  of the temporary containment  barrier with polyethylene  sheets or
 8prayed-on strlppable coatings is one of trie most basic engineering controls.  The
 primary objectives of work area preparation are:
       • Preventing the migration of fibers outside the work area
       • Protecting the surfaces Inside the work area
       • Decreasing the difficulty of cleanup

 The sequence of tasks for work area preparation will vary with each site configuration, type
 of ACM, physical condition of the ACM, and design of the heating, ventilation  and air
 conditioning (HVAC) system.  For example, If the ACM is in poor condition and it is likely to
 be disturbed during work area preparation and if there is visible asbestos-containing dust
 that has settled onto surfaces, workers would need to wear personal protective equipment
 in the initial stages of work area preparation.  The following are general guidelines and
 considerations for preparing the  work area for asbestos removal. They may  need to be
 modified to address site-specific concerns.  These guidelines are most applicable  in
 situations where  spray-applied surfacing  ACM is  being removed.  Though the same
 concepts of containment apply  to thermal system  insulation (TSI) and  miscellaneous
 materials, modifications of preparation techniques will be necessary.  Appendix B contains
general procedures for removing TSI with a glovebag.

 Task 1: Post Danger Signs

 Generally,  one of the first things done when the contractor arrives  on site is posting of
danger signs and barrier tape to help keep unauthorized and unprotected people out of

-------
STUDENT MANUAL                                       AS8ESTOS ABATEMENT PROJECT DESIGN

                                                                             Pago 3
the work area.  OSHA requires that a danger sign such as the one shown in Figure V-1
be posted at each of the possible entry points into the abatement project  This would
indude the entrance to the decontamination unit and the exterior door of the waste loadout
area(s), as well as other entrances or exits.  Signs should be placed so they can be read
from a distance far enough away so that persons can avoid the area or take necessary
precautions.  These black, red and white sfgns can be obtained from asbestos abatement
supply companies.

Task 2: Test Stationary Mechanical Equipment

If  it  was  not already done during  the preconstruction  walk through, any equipment
remaining in the work area should be tested to determine if it is operational before being
unplugged and covered.  Any nonfunctioning equipment and pre-exsisting damage (i.e.,
cracked windows, marred walls, etc.) should be documented before abatement begins.
Pre-existing damage should be agreed upon by the contractor and owner's representative
before work begins.

Task 3; Isolate the HVAC System

The  HVAC system servicing the  area  is shut down  and  locked out and openings are
sealed to  avoid entrapment  of asbestos fibers throughout the building, contamination of
the HVAC system, and buildup of positive pressure in the work area. The project designer
has at least two important considerations with respect to the HVAC system.  The designer
must designate whether all or part of the duct work should be cleaned, removed, or left in
place.  The project designer may need to call upon an industrial  hygienist to assist in
determining rf there is asbestos contamination inside the duct work.  Sometimes asbestos-

containing overspray  was  inadvertently sprayed  into open duct work during initial
construction. This overspray may be sporadic and difficult to detect without an extensive
and time-consuming inspection of the duct system.

In addition to specifying what should be done with the HVAC system in the work area, the
designer must also determine whether the HVAC must remain In operation for other parts
of the building.  If so, special procedures may need to be followed to  isolate the operational
system from the work area.  Often floors  in a high-rise building are  serviced by individual
units and it is simple to shut down and lock out the HVAC system on one floor without
affecting other  floors.  In other instances one large unit may service several floors and
measures must be taken to truncate or reroute the duct work. The system may then need
to be rebalanced to avoid over pressurization in the occupied portions of the building. The
building  owner's engineer or a mechanical  engineer needs to be  involved with any
modifications of the HVAC system.

Task 4: Critical Barriers

After the  HVAC system servicing  the work area has been shut down or rerouted, the
exposed vents, diffusers. grilles, and air  ducts inside the work area are cleaned with a
HEPA  vacuum, wet wiped, and covered and sealed with two layers of 6-mil polyethylene
and rinrtfopft  The first layer of polyethylene forms a critical barrier and is left in place until
final clearance air monitoring results indicate the area is ready for reoccupancy. In order to
leave this critical barrier in place, the second layer of polyethylene must be cut larger than
the first and taped so it  can be removed separately.

 In addition to the HVAC vents and ducts, critical barriers are placed over windows and
 doors not used for access. To make a more airtight seal, three-inch duct tape is used to
 cover the seams around the windows, then two sheets of 6-mil polyethylene are taped
 around the perimeter of the windows and doors.  Rigid barriers constructed of plywood or
 an equivalent may be needed to block off hallways or divide large rooms.

 Task 5: Conduct Initial Cleaning of Work Area

 Al objects and horizontal surfaces, with the exception of substrates covered with ACM.
 should be initially cleaned by wet wiping with amended water. Wiping with plain water is
 recommended for surfaces that may be damaged by the chemicals in amended water and
 delicate wood surfaces may need to be wiped with an  oil cloth. A technique  that is
 effective for removing surface contamination is wiping in one direction and folding the cloth
 over to expose a dean surface prior to making the next wipe.  Once an dean surfaces of
 the doth have been used it Is discarded as asbestos-containing waste.  A HEPA vacuum is
 useful for deaning  up  visible dust or  debris on surfaces prior to wet wiping.  Property
 trained workers performing  the initial cleaning should wear, at a minimum,  half-mask
 respirators and disposable suits.

 Task 6:  Remove Nonstationarv Items From Work Area

 The design specifications must clearly identify  what will be  removed from the work area
 and what will remain.   It is typically  best  to  remove  all  nonstationary items to avoid
contaminating the items and to allow better access for scaffolding and other equipment.
The specification should also make  It dear who  has the responsibility (owner or contractor)
to  remove nonstationary items. Typical items which would be removed from the work area

include office equipment, office furniture, draperies, etc. A storage area for these items
should be designated in advance. In some cases the  storage area may not be convenient
to the work area and several hours are required to transfer the items.

If there is carpeting in the area, the designer must specify whether it will be removed and
disposed of as asbestos-containing  waste; cleaned and removed as non-ACM; or left in
place, cleaned with a  hot-water vacuum cleaner and covered with protective layers of
polyethylene.  The decision is influenced by the condition and age of the  carpet and the
degree of contamination. Studies have indicated that  a hot-water vacuum cleaner is more
effective than a HEPA vacuum for removing asbestos from carpets.

When feasible, disposal of contaminated carpet is preferable to cleaning it. Usually if the
carpet has been in place for a long time, the adhesive  and some of the carpet backing may
stick to the floor when  the carpet is taken up.  The adhesive may be difficult to remove,
requiring unanticipated additional time to prepare the area. A test should be conducted
before work begins to determine the degree of difficulty in removing the carpet and
underlying adhesive. Upon removal,  the carpet is rolled up, sealed in a layer of 6-mil
polyethylene and  disposed  of as asbestos-containing  waste. As a precaution, the carpet
can be cut up and/or defaced to prevent the possibility of reuse.  Worker's  performing this
task should mist the carpet  with amended water to a point when the carpet is damp. The
workers should wear protective clothing and respiratory protection.

The project designer should also provide guidance  on handling  draperies and  fabric-
covered furniture.  Unless there is evidence of heavy contamination, furniture is  usually
HEPA vacuumed  or cleaned with a hot-water vacuum.  Draperies can be disposed of as
asbestos-containing waste or carefully HEPA vacuumed and stored.

 Replacing or cleaning and storing the light fixtures is a site-specific decision that must be
 made by the building owner and the designer.  Often, light fixtures must be moved to
 access the ACM.  They can be detached, suspended with wire, cleaned and covered with
 polyethylene.   The  problem with  this approach  is  that water may  leak inside the
 polyethylene and the lights wil need to be recteaned.  Alternately, they may be removed,
 cleaned and stored outside the work area.  Building owners often elect to replace older
 light fixtures with  new energy-efficient  lighting equipment.  The ballasts in light fixtures
 installed prior to 1978 may contain polychlorinated biphenyls.  If PCB-containing ballasts
 are leaking  or are disposed of in  large  quantities,  they may be subject to  disposal
 regulations.

 If new fight fixtures are installed, the specifications should be dear about who will pay for
 the fluorescent tubes and  their installation. The light  fixtures are usually one of the last
 items addressed in work area preparation because the electrical supply must be  shut off.
 tagged and locked before the lights are disturbed. Also, if the lights are affixed to the ACM
 on the ceiling, it is likely that fibers  will be released while  the light fixture is being  taken
 down. For these reasons, it is best  to cover the floors and walls with polyethylene before
 disturbing the light fixtures.

 Task  7:  Cover and Sea/ StatiQQpry Ottfects

 After the surfaces have been cleaned and all nonstationary objects have been taken  out of
the work area, any remaining stationary items  such as water fountains, thermostats,
radiators, chalkboards, sinks, machinery, etc. are deenergized. as necessary, and covered
with separate layers of 6-mil polyethylene.  Each layer is securely taped  in an attempt to

Task 8: Deenenpize Electrical System

Once removal begins, the use  of amended water to saturate the ACM creates a humid
environment and wet,  slippery floors.  This increases the potential for a shock hazard. If at
all feasble, electrical  service to the project area should be shut off and the breaker box
should be locked and tagged.  However, the breaker box should  not be locked if it also
contains energized circuits for nonabatement areas.  Individual breakers may need to be
locked out

The designer should specify that the contractor provide temporary electrical service that is
equipped  with ground fault interrupters  from outside the work area.  It  is critical that
extension cords are positioned so that they will not  be  lying in water once the project
begins.

In some cases it will not be possfole to disconnect the electrical supply. For example, a
bus duct which supplies electricity to many areas of an occupied building and must remain
operational may run through  the work area. If the electrical system cannot be shut off, then
energized parts must  be insulated or guarded from employee contact and any objects that
are conductive. Switch gear, transformers, and electric bus ducts  often generate heat.  It
may be necessary to  construct  an enclosure around these items and provide dean, cool
air  to the enclosure for ventilation.  Electrical conduit is not water tight and will need to
have fittings caulked or sealed with vinyl tape or tape and polyethylene.

If electrical systems within the work area must remain energized, then wet removal is not
recommended because of the risk of fire or electrocution.  In accordance  with NESHAP
regulations, dry removal requires notification and consent by EPA prior to project startup.

The layers of wall polyethylene are hung using a combination of nails and blocks of wood,
continuous furring strips, or adhesive and staples, and sealed with wide masking tape or
duct tape.  Duct tape alone Is not sufficient to keep the polyethylene In place
for the du  tton of the project.  These additional methods may cause some damage
to interior finishes and the contractor will need to  make minor repairs upon completion of
removal.

The second layer of 6-mll polyethylene is placed on the floor with the seams of the first and
second layers offset and extended just above the  first layer on the wall and attached with
duct tape.  Then, the second layer of 4-mil polyethylene is secured to the  wall just above
the first layer, extended to the base of the wall just beyond tie bottom of the first layer and
sealed with duct tape.  At this point there are two continuous layers of polyethylene
encasing the entire room except for the ceiling.  Because wet polyethylene  creates serious
sup and trip hazards, extra precautions are necessary for stairs or ramps. Masking tape or
thin wooden boards can be placed on top of the polyethylene to provide better friction.
Textured polyethylene has been effective in reducing slip hazards.

Although it is more expensive than standard polyethylene, fire-retardant  polyethylene is
preferable because of the added safety factors. It reduces the possibility of a fire starting
and spreading outside the containment area.  Its rough texture also reduces the potential
for slips and faBs.

Sp  yed-on strtppable coatings can sometimes be used as an  alternative to sealing
the area with sheet polyethylene. The latex/water based material te sprayed onto surfaces
with an airless spray pump to form a continuous, somewhat elastic barrier.  It is outside the
scope of this course to provide detailed instructions for applying strippable coatings and

 project designers are encouraged to contact manufacturers for information on job setup
 and procedural specifications.

 Propping an area with a strippabte coating is more complex than using polyethylene, but
 depending on the surfaces and project configuration, there may be distinct advantages.
 While it is not applicable to every job. it is an alternative method with which designers
 should be familiar.  The potential advantages compared to sheet polyethylene Include a
 faster application time, elimination of "rehang time" to keep sheet polyethylene in place.
 less contaminated waste to dispose of, less slippery floor surfaces,  and no ballooning
 effects.  The  potential disadvantages compared to sheet polyethylene include a more
 complex application method, some difficulty in removing the strippabie coating when the
 job is finished, and the presence of ammonia requiring combination high efficiency and
 ammonia respirator cartridges during installation.

 When spray polyethylene is used to prepare a containment area, sheet polyethylene must
 still be used to form critical barriers over windows, doors and other openings.  Then the
 spray polyethylene is applied over critical barriers.
     10' EstaNishin  A Decontamination Unit
Usually the decontamination unit is built while the work area is being prepped. There may
be a need to build the decontamination unit first so workers can use it during work area
preparation.

The OSHA  asbestos  standard (29  CFR 1926.58)  requires  the contractor to
provide  a  decontamination unit for  workers which consists of an equipment

room,  a shower area and a  clean  room.  As an  additional precaution  it is
recommended to separate the rooms with airlocks.

The purpose of the decontamination  unit is to allow passage to and from the work area
during asbestos removal while minimizing migration of asbestos fibers to the outside.  The
design  of the decontamination station  may vary with each project  depending on the
physical constraints associated with  the faclity,  the crew sizes and the duration of the
project

A variety of materials can be used to build decontamination units on site including wood,
PVC and polyethylene.  Customized trailers and prefabricated units which can be moved
from one site to the next are also used as decontamination stations.

The decontamination unit is often bunt in  sections to allow for easy disassembly and reuse
(of  noncontaminated components) at other areas of the building or other job sites. A
typical unit built of wood might consist of  2" x 4' lumber for the frame, 1/4' to 1/2" plywood
or 6- or 10-mi polyethylene for the walls,  duct tape, staples and nails.

Two common layouts for a decontamination unit are provided in Figure V-2 and Figure  V-3.
The first layout shows  both the equipment room and the waste loadout  unit directly
adjoining the work area. An  alternative configuration is provided in  the second layout
which shows the waste loadout adjoining the equipment room of the decontamination unit.
This configuration can be used when a second opening into the work area is not available
or convenient.

The functions of each of the components of a decontamination unit are descrfoed below
and procedures for entering and exiting the work area are provided in Table V-1. While
the specifications usually do not detail the dimensions of the decontamination unit, general
requirements such as numbers of chambers and airlocks should be included.  It should
also be emphasized that  a separate  waste  loadout area will be established and no
equipment  or  waste should be passed through the shower and dean room of
the  decontamination unit

Clean Room -  As  described In the OSHA standard (1926.58) the clean room is an
uncontaminated  room having facilities for the storage of employees' street clothing and
uncontaminated materials and equipment.  It is an area in which employees remove  their
street dothes, store them, and don their respirators and disposable protective clothing.
This room is where  workers  dress in clean clothes after showering.  Furnishings for the
clean room should include benches, lockers for dothes and valuables, and shelves for
storing respirators.  Extra disposable coveralls and towels can be stored in the dean
change room.

Shower Room - The shower is located between the dean room and the equipment room
and  is separated from each  of the two by an airlock (see  Figure  V-2).   Workers pass
through the shower room on  their way to the removal area and use the showers on  their
way out after leaving contaminated clothing in the equipment room. The  shower should
be  of a  pass-through design,  reducing the  chance of workers  tracking through  a
contaminated area on their way to the clean  room. Although most  job specifications
require only  a single shower  head, Installation of multiple showers may be time and cost
effective  if the work crew is large.  While there is no mandatory requirement, some
designers specify a minimum of one shower head per five workers. Coid and hot water

should be supplied with separate controls, and in ample capacity for each worker to have
at least a three-minute shower.  Local or state regulations can govern number of shower
units and requirements for providing hot water.

Shower  wastewater should  be  drained,  collected  and  filtered  through  a
system  before  disposal  Into  the  sanitary  sewer.   The lack of  adequate
accommodations for  filtration of shower water is a common problem  on abatement
projects.  A system containing a series of several  filters with progressively smaller  pore
sizes (100, 50, 5 micron) is recommended to avoid rapid initial clogging of the filtration
system by larger particles.  Also a holding tank for shower water helps avoid exceeding the
capacity of the filtration system.  Wastewater may need to be retained in sealed barrels or
containers and/or holding tanks for appropriate disposal. Some states, including Alabama.
Georgia, Maryland and  New Jersey  have written  regulations  for  handling shower
wastewater. The designer should consult local regulations.

Equipment Room - This area, also called the dirty change room,  is the contaminated area
where workers  remove their protective coveralls and where equipment, boots or shoes.
hard hats, goggles, and any additional contaminated work clothes are stored.  Workers
place disposable clothing such as coveralls,  booties and hoods in waste disposal bags
before leaving this area for the shower room.  Respirators are worn into the shower and
cleaned  with water before taking off.  The  equipment room usually requires cleanup
several times daily to prevent asbestos materials from being tracked into the shower and
dean rooms.

Airtocks- Airlocks are formed  by overlapping two sheets of polyethylene at  the exit to one
room  and two sheets at the entrance to the next room with at least three feet of space

 between the barriers.  There are various methods used for constructing airlocks including a
 hatch-type construction, a slit and cover design, or strip curtains such as those used on
 loading docks.  Airlocks must be constructed to effectively maintain negative pressure
 whie not inhibiting worker egress in an emergency situation. It is also critical to provide an
 alternate emergency exit from the containment area  to  comply with OSHA safety
 requirements and to protect the workers.

 Waste Loadoitf Area - The waste loadout area (separate from the decontamination unit
 and not used for personnel egress) is used as a short-term storage area for bagged waste
 and as a port for transferring waste to the truck. An enclosure can be constructed to form
 an  airlock between the exit of the loadout area and an enclosed truck (see Figure V-2).
 The waste loadout  area normally is equipped with water used to wipe off the exterior
 surface of the bagged asbestos waste or drums. Workers from inside the work area place
 containers of asbestos waste into the airlock between the waste loadout area and the
 truck. A different group of workers moves the waste from the airlock onto the truck.  The
 waste loadout area must have a locking door to prevent entry from the outside.

 REMOVAL OF ACM - CONFINING AND MINIMIZING AIRBORNE FIBERS

The primary  engineering controls  used  In the  removal  phase of an asbestos
abatement project are the use of amended water to wet the ACM and  the use
of HEPA filtration units to filter  fibers out of the air and establish a negative
pressure differential Inside  the work area.

states that "whenever feasible, the employer shall establish negative pressure enclosures

before commencing  removal, demolition  and renovation operations.*  Though the  EPA
does not have a specific requirement, it endorsed the concept of air  filtration systems as an
effective control technique on asbestos abatement projects In  the early 1980s.  Negative
air filtration  systems are  used on abatement projects not only  to meet regulatory
compliance but to accomplish several positive effects including:
       •  Containment of airborne fibers  inside the work area
       •  Dilution (by filtration) of tne  airborne fiber concentration in the work area
       •  Improved efficiency in final cleanup
       •  Improvement in worker comfort providing increased productivity

The containment system is a combination of  the physical  enclosure, the number and
placement of air filtration units and  the number and locations of make-up air inlet(s). A
variety of designs  have evolved for  establishing containment systems  for asbestos
removal.

One of the earliest systems is described in EPA's •Recommended Specifications and
Operating Procedures for the Use of Negative Pressure Systems  for Asbestos Abatement*
(Appendix A of this manual). This information was first published  in  a  1983 EPA Guidance
Document In this design, air filtration units are used to filter asbestos fibers out of the air
and exhaust it outside the work area, while pulling uncontaminated air into the work area
through the decontamination unit. The air is moved by centrifugal fans housed in steel.
fiberglass or aluminum "boxes.*  The air  is filtered through two  preliminary filters, and a
HEPA fitter, and then vented to the outside of the work area.

A variation of this concept is to recirculate the air by exhausting some of the air filtration
units inside the containment area.   A hard door instead of polyethylene  or vinyl flaps is

 used on the decontamination unit  Negative air is maintained by exhausting only enough
 air from the containment to overcome leakage.

 Another containment strategy involves  using  a HEPA-vent make-up air Inlet  device
 inserted in a solid door on the decontamination unit.  The louvered vent allows air to enter
 containment based on the demand of the air filtration units and the amount of negative
 pressure desired.

 Each of the containment systems discussed, and hybrids of these systems, have been
 demonstrated to be effective on asbestos  removal projects when the techniques  are
 properly appied. Some projects, depending on the  physical  parameters of the site,  may
 be better suited to one type of system.  The project designer is encouraged to become
 familiar with the various possibilities in designing containment systems and to collaborate
 with knowledgeable abatement contractors in developing the  best system for a particular
 site.

 The remainder of this discussion will focus on special problems or considerations related
 to using air filtration units that the project designer  may need to address in the design
 specifications.  These issues  include pressure differential across the containment barrier,
 number of air changes per hour, and potential for leakage of contaminated air through the
 air fltration units.

 Leakage of Contaminated Air-  In the event there is a leak in the  system, it has always
been the recommended practice to exhaust HEPA air  filtration units to the outside air rather
than back into another part  of  the  building.  In 1990  EPA published a  performance
evaluation of in-piace HEPA filtration systems at asbestos abatement sites that strongly

                                                                             Pap 21
supports the necessity of this practice.  The study found that 16 percent of the 31 units
tested showed particle efficiencies lower than the American National Standards Institute
criteria for nuclear air cleaning systems of 99.95 percent with 0.7 - 0.8 um particles.  The
study suggested that the substandard performance may have resulted from damaged or
improperly installed HEPA  filters, from  leaks in the mounting frame,  or between the
mounting frame and the housing, all of which could cause the air to bypass the HEPA filter.

In an attempt to deal with this problem of potential leakage the designer should consider
specifying the following requirements:

       • Documentation from the contractor that each of the  HEPA filters used in  the air
        filtration  units on  site has been individually  tested and certified by the
        manufacturer to have an  efficiency of not less  than 99.97 percent when
        challenged  with  0.3 micrometer dioctyl  phthalate (OOP)  aerosol.  Each filter
        should be marked  with the name of the manufacturer, serial number, air flow
        rating, efficiency and resistance, and direction of test air flow.

       • A visual inspection of aO HEPA filtered units, once they are on site, for evidence of
        damage to  the  HEPA filter and evidence that the filter is properly seated in
        position.

       • Al HEPA filtration units must be exhausted to the outside air.

In most situations venting the HEPA filtration unit to the outside Is not a problem.  Windows
may have to be removed and wooden templates inserted or flexbte ducts may need to be
connected to a roof ventilation pipe.

 There will be rare occasions where no outside access is available adjacent to the work
 area and it is not feasible to run flexible or rigid ducting the necessary distance to access
 an outside vent.  In these  cases it  would seem  logical to test the  exhaust air for
 contamination but there  is not a quick, reliable method for testing the  efficiency of air
 fHtratjon units.  To representatively sample the  air being exhausted out of the  HEPA
 filtration unit for asbestos fibers, the air samples would have to be collected at the same
 velocity as the exhaust air.  This is termed isokinetic sampling and is not practical with the
 standard air sampling methods used on abatement projects.  Methods used in previous
 research studies require  the use of an aerosol generator and aerosol photometer which
 are not routinely available.  Area air samples could be collected in the vicinity (not directly
 in line) of  the exhaust air,  but even if the analyses of these  samples were done using
 transmission electron microscopy (TEM) which is currently the best available method, there
 is no validated technique  or established statistical reliability for this procedure.

 One design alternative, when exhaust air must be vented inside the building, is to exhaust
 it through a HEPA filtered unit into a sealed chamber,  and then exhaust the air from the
 chamber through  a second HEPA filtered unit.  This provides a second opportunity for
 filtration of the air before releasing it into the building.  With this configuration, care must be
 taken to avoid placing the chamber under positive pressure.

Another option that is available is utilizing a secondary wet filter system where air from the
 HEPA filtration system is forced  through a unit  with a water  reservoir before being
discharged into the building environment.  Ideally any fibers in the air are captured when
the air is diffused through the water. No test data is currently available for this system.

Again  It Is emphasized, H at all  possible, the  exhaust from HEPA filtered
units must be vented  to  the outside air to minimize  the potential for building
contamination.

Pressure Differential Across  the Containment Barrier — The  establishment of a slight
negative air pressure inside the work area using HEPA-filtered systems reduces the
potential for migration of fibers outside the work area. Standard practice in the industry
has been to establish a pressure differential between the work area and adjacent spaces
of 0.02 to 0.03 inches water gauge (w.g.). and maintain four air changes per hour.  Recent
studies have shown that pressure variations exceeding 0.02 to 0.03 inches of w.g. inside a
work area can be caused by changes in atmospheric pressure and wind velocities.  Some
states are considering a requirement  to Increase the  pressure differential  across the
containment barrier to 0.05  or 0.1  inches w.g. to allow for atmospheric variations.   If a
removal project is being conducted in an occupied building or in an area or time of  year
subject to wide variations in atmospheric pressure or wind velocity, the designer may need
to consider requiring a higher pressure differential.

It Is usually the responsibility of the air monitoring firm working for the  building owner to
measure and document the pressure differential.  Measurements can be  taken  with a
manometer.  Typically, instruments which monitor the pressure drop continuously are
connected  to strip chart recorders to provide continuing documentation of the pressure
differential.  Some instruments are equipped with an audible alarm to alert  the project
personnel of a severe pressure drop.  Measurements of the pressure differential should be
taken daiy from a number of locations around the perimeter of the project area.  Extensive
pressure monitoring serves  as a valuable tool in preventing fiber migration outside the
work area.

 Air  Changes Per Hour-There  is  not a direct  relationship  between  pressure
 differential and number of air changes per hour.  For example, in a  wind tunnel
 there may be many air changes per hour with no significant pressure drop between the
 inside and outside of the tunnel. Conversely, the more leak tight an area is, the easier it is
 to estabish a pressure differential.

 The recommended air change rate is based on  engineering judgement. As previously
 discussed, the industry standard has been four changes per hour. On projects where high
 airborne fiber concentrations are anticipated, there  may be a need to  increase the air
 changes per hour in an attempt to increase the filtration rate for asbestos  fibers.  The
 number of HEPA filtration units necessary to achieve the required air changes per hour
 can be determined by first calculating the total volume of the work area and then dividing
 this volume by the desired air change rate. This establishes the total volume that needs to
 be exhausted from the work area each minute.

   total cubic feet/minute (CFM) - volume of work  area (in cubic feet) + 60 minute/hour
                                                        number of air changes/hour

 Then the number of units needed for the work area is determined by dividing the total CFM
 by the rated capacity of the HEPA filtration unit.
   number of units needed       -       CFM	
                                capacity of unit (CFM)
The following example is provided for a work area that is 50 feet wide by 200 feet long by
10 feet high with an assumption that the available HEPA air filtration units have a nominal
rated capacity of 2000 CFM and the number of desired air changes per hour is 6.

    total CFM - 10,000 CFM
    number of units needed » 10.000 CFM    = 5
                            2,000 CFM
    number of units needed plus safety factor = 5 + (5 x .5) - 7.5 round to £

One potential problem in using this method for calculating the necessary number of HEPA
filtration units is the use of the manufacturer's specified nominal air flow rate. Tests on
HEPA units operating under field conditions indicate there  may be as much as a 50 to 60
percent reduction of actual air flow compared to the manufacturer's rating. Assuming the
filtration units are  operating at the manufacturer's specified nominal air flow  rates could
result  in actual  ventilation rates significantly below project design specifications.  The
project designer may want to consider adding a required safety factor in  the range of 25 to
50  percent more  units  than  the calculated number using the  manufacturer's rating.
Alternatively, on-srte testing of in-piace units should be conducted  to determine the actual
exhaust rate. The  designer should also require that extra exhaust units be available at the
job site to  replace  ones that malfunction.  One  extra unit for every five in operation is a
typical requirement

 WET REMOVAL OF ASBESTOS-CONTAINING MATERIAL
 Thoroughly wetting friable ACM prior to removing it is a key engineering control which
 serves two important functions:

       • Fewer fibers are separated from the material and released into the air as removal
         takes pi ace.

       • The ACM is usually easier to remove after it has been saturated.

 Recognizing these advantages, EPA regulations require (since  1973) that ACM be kept
 wet before, during and after it is removed until it is placed into the disposal containers.
 Improper wetting  of the material is  one of the most common citations associated with
 asbestos removal projects.

 The benefits of  wet removal can be further enhanced by adding  chemicals to
 the water that Increase Its ability to penetrate the  material.  These  chemicals
 are caBed wetting  agents or surfactants. Water to which these have been added te called
 amended  water.  Various  wetting agents are available which have been used in
 agriculture and fire fighting for many years. The type commonly used for asbestos removal
 contains 50 percent  polyoxyethylene  ester  and 50  percent polyoxyethylene ether.
 Typically, the spray mixture contains one part amended water and five parts water.

Amended water is most effective on materials containing chrysolite asbestos. It generally
is not as effective  with materials which contain  a high percentage of amosite or  crocidolite
asbestos because amphiboles as a  class are hydrophobic (lacking  affinity for water).

There are available alternatives including 'removal encapsulants" which are modified so
that they minimize fiber release but do not harden the ACM prior to removal. The project
designer will want to review documentation of all materials and supplies being used on the
project prior to start up as a means of ensuring the products being used are suitable for the
job.

Removgl Q( fflfflfr/fl Surfacing ACM

 If the work area has been properly prepared, removal is usually a straightforward process.
Some states are now  requiring an inspection of the work area by a state inspector before
removal activities  begin  to  ensure the work area has been  properly sealed, the
decontamination unit and HEPA filtration units are in place, and the proper equipment and
materials are on site.  A project designer may want to consider including  a requirement for
an inspection by the project monitor at this stage of the project if it is not a state or local
requirement.

The first step In the removal process  Is to thoroughly wet the ACM with a
low-pressure  mist of  amended  water, allow time for soaking action and then
saturate the material with a second application. If time allows, the ACM should  be
thoroughly saturated 12 hours in advance  of removal to allow for maximum penetration of
the ACM.  (Note:  The added weight of  the  amended water may cause the material to
delaminate prior to removal.  If the  ACM is on a suspended metal lath ceiling, there is
potential for collapse of the  ceiling due to added water weight. The integrity of the ceiling
supports should be checked prior to wetting the ACM.)

 One of the most common insurance claims on abatement projects is water damage. Water
 damage te often caused when workers forget to shut off water to pressure spray hoses at
 the end of the day and a leak occurs overnight.  Application with large pumped systems or
 airless sprayers with high water pressure may result in leakage behind the barrier seals to
 the outside of containment.

 Removal of the celling material  Is generally carried out In  two stages by first
 removing the gross material and  then conducting a  detailed cleaning of the
 substrate.  Gross  removal is effectively  conducted with a three- or four-person team.
 Workers stand on mobile scaffolding or ladders  to scrape the material from the substrate.
 One or two workers on the floor, package the moist ACM in 6-mil polyethylene bags  or
 lined fiber drums before it has time to dry  out.  The ACtf must be bagged  and sealed
 continuously  and never allowed to remain on the floor overnight.  Allowing
 ACM to dry out will result  in high  fiber concentrations.  The material is collected  and
 bagged using equipment such as dust pans, snow shovels and push brooms constructed
 of rubber or plastic to minimize the damage to the polyethylene barrier. The crew that bags
 the material also repositions the scaffold as needed. For large removal operations it may
 be more efficient to designate a 'spray* person to walk from one area to the next, keeping
 the ACM on the ceiling and floor wet and misting the air to  maintain low airborne fiber
 concentrations.

 Bags containing waste are wet wiped, placed into another dean bag or placed into lined
fiber drums as they are placed into the waste loadout area.  Removing bags out of the work
area on  a continuing basis helps keep  the work area dear  tor easier access and
movement.

After removing as much of the sprayed-on material as possfole with scrapers, crews begin
secondary removal.  During this phase workers use  a combination of brushing and wet
wiping to remove the remaining  residue.  Typical tools include various sizes of nylon
brushes, lint-free rags and a HEPA vacuum.  The difficulty of secondary removal depends
on the texture and configuration of the underlying surface.  Figure  V-4 illustrates some of
the common  types of ceiling  construction which include concrete, a three-coat plaster
system, suspended metal lath, concrete joists and beams, metal deck, corrugated steel.
and steel beam or bar joist.   One of the most difficult areas to access are  the grooves
formed at the junctions of the corrugated deck and beam.  It  is a tedious process using
small brushes to clean out these spaces. Rough, rusted and pitted surfaces can also be
very time consuming to decontaminate.  The design specifications should provide
a description of the type of substrate  In the  project area and  the criteria that
will be used to  determine  if the  substrate Is clean.

Also the specifications should specifically address ACM In areas that are difficult to access
such as elevator shafts, soffits, exterior beams, etc.  In some cases the designer may
specify encapsulation or enclosure in areas where ACM cannot be effectively removed or
where replacement material cannot be effectively installed.

Whle crews perform detailed  cleaning to remove an remaining residue from the ceilings.
workers use brooms,  wet/dry HEPA vacuums, wet rags and squeegees to dean ACM off
the polyethylene and  other stationary objects. When all visual contamination is removed
from the substrate, secondary removal is complete.  The next phase is final cleanup.

Removal of Thennal System Insulation from Pipes. Boilers and Tanks

There is a wide variation in the types of asbestos-containing thermal system insulation
used on pipes, boilers  and tanks.   Pipes may be insulated with  preformed fibrous
wrapping, corrugated paper, chalky mixture containing magnesia, fiber felt and insulating
cement  (Note:  There are older materials labeled "magnesia" which contain asbestos and
new materials also labeled 'magnesia* which contain glass fiber rather man asbestos.)
Usually a protective jacket, which may also contain asbestos, made of paper, tape. doth.
metal, or cement covers the insulation materials.  Boilers and tanks may be insulated with
asbestos 'blankets* on wire lath, preformed block, or the chalky magnesia mixture which is
typically covered with  a finishing cement.  Different approaches are typically required for
removing  these asbestos-containing  materials  than  sprayed-on or troweled-on ceiling
insulation;  however, the same protective measures are used.  Careful handling and
packaging  is required in many cases  because of the metal jackets, bands, or wire
associated with the insulation materials.

Important considerations in developing  the  design specifications are the temperature,
contents and condition of the thermal system.  If at all posstoJe, high temperature lines
should be deactivated  before removal takes place. Removal from hot pipe requires special
protective equipment and procedures to  avoid damaging the pipe or injuring workers.  In
some industrial settings pipes may contain toxic  materials that could cause a serious skin
or Inhalation hazard if released due  to damage.  It is often difficult to determine the
condition of insulated tanks or pipes. Older systems may have rusted or corroded sections
that could  be easily damaged during removal.   This would result in  the release of the
contents of the pipe or tank into the work area.

 Gtovebags, which can be sealed around sections of pipe to form •mini-containment areas"
 may be used in some situations for removing pipe insulation.  Insulated objects which are
 not readty accessible or are too large or hot for application of the glovebag technique, may
 require a full area enclosure with modified removal techniques.  Standard glovebags
 should not be used on pipes that are hotter than 150°F.   Procedures and equipment for
 using a glovebag are outlined in Appendix B.

 Because  insulation on pipes,  boilers and tanks may often contain as much as 70%
 asbestos and because areas where these materials are being removed are often confined,
 high airborne fiber concentrations may occur.  Also, these materials are more difficult to
 saturate with water because they are often covered with  an outer jacketing. They often
 contain amosite, which is not controlled as well with water as other types of asbestos. If
 these  situations cannot be controlled by higher air  flow rates and other engineering
 techniques, then Type C airline respirators are recommended for workers engaged in
 removal of asbestos from pipes  and boilers.

 Removal of insulation from pipes, tanks and boilers can be accomplished by two-person
 teams.  Cuts or slits are made in the insulation material, a spray nozzle is inserted, and the
 material is wetted to the extent feasible. One person cuts away the insulation and bags it
 while the other continuously sprays the material with amended water. Any metal bands or
 wire that are removed should be folded or rolled and placed in polyethylene to avoid injury
 to personnel.

 After the gross material is removed,  nylon brushes are  used to thoroughly dean the pipes.
 tanks or boilers.  (In cases when pipes are extremely hot, nylon brushes may melt and wire
brushes may be  the most feasible tool.) Particular care must be taken to dean the fittings

and joints where a cement-plaster type material has  been removed. After brushing, the
surfaces are wet wiped and the final cleanup phase begins.
DRY REMOVAL TECHNIQUES

Dry removal, which requires specific EPA approval, may be appropriate for some types of
asbestos-containing materials which have been previously encapsulated and will  not
absorb amended water. There are special conditions which may preclude the use of water
such as a room containing electrical supply lines which cannot be deenergized during  the
removal project,  hot steam pipes, below freezing weather, etc.  Dry removal  techniques
can be used successfully but require much skill and attention to critical details in order to
minimize airborne fibers in the workplace and to adequately confine all airborne fibers to
the workplace enclosure.  It Is very  Important that  all personnel use  maximum
personal protection  during  dry  removal  because of the constant  and high
potential for elevated airborne fiber levels.

The dry removal procedures selected for a given situation  must be carefully matched to the
existing work area conditions, the type of asbestos and the skill of the work force.  Adding
layers of enclosure  plastic,  adding airlock chambers  to the decontamination  units,
providing double or triple,  rigid primary barriers (in addition to several layers of primary
polyethylene), and increasing  the  number  of  negative  pressure  machines may  be
precautions that are required beyond the normal wet removal procedures.  These  added
confining and minimizing measures obviously add cost to the project It is always much
easier to control airborne fibers using wet techniques.   It is  recommended that all
reasonable and safe avenues  for wet removal be thoroughly explored before resorting to

 dry removal.  Dry removal requires EPA approval and approval is sometimes difficult to
 obtain.

 CLEANING UP THE WORK AREA

 Final cleanup of the work area begins when all visible ACM has been removed from the
 substrate.  Successful cleanup requires proper sequencing of tasks and attention to detail
 to avoid recontaminatjon of dean areas. Clean-up activities for thermal system insulation
 and miscellaneous materials may vary, but the strategy will remain the same. While the
 project  designer may  allow  the contractor to determine the most  effective  cleaning
 sequence,  there may be some specific requirements that the designer will want to include
 in the design specifications, such as time intervals between cleaning activities.

 One sequence for cleaning up an area after removing surfacing ACM is discussed below
 and shown in Figure V-5. This sequence is typical, but not inflexbte. Some model/master
 specifications, and even state regulations, may suggest or require a different approach.
 The area of most variability seems to be when to take down the inner and outer  layers of
 polyethylene.  In  the sequence discussed below, the first layer of polyethylene is taken
 down before the lockdown material is applied.

 An alternative sequence in which the lockdown material is applied while both layers of
 polyethylene are still in place is proved in Figure V-6.  This sequence is outlined  in the
American Society of Testing and Materials (ASTM) E1368,  "Standard Practice for Visual
 Inspection  of  Asbestos Abatement Projects.'  This procedure also provides  specific
guidance for conducting visual inspections of the substrate and the asbestos removal work
area prior to final clearance monitoring.

Conduct Visual Insoection of Substrate. Redoan tf Necessary

This  is  a  good  point  for the building  owner's representative and  the contractor's
representative to make sure that there is not residual material on the substrate from which
the ACM has been removed.  The contractor's representative is responsible for correcting
any of the deficiencies noted before beginning the next phase of work.

Remove Qross Contamination from Equipment and Potysflivtene

After the visual inspection  indicates the ACM has been totally removed from the substrate.
all visible material is cleaned from the exposed  layer of polyethylene and surfaces of
equipment Including scaffolding, ladders, extension cords, and HEPA filtration units.
Cleaning Is conducted by wet wiping and HEPA vacuuming.  Any equipment that is not
necessary to complete the project is thoroughly cleaned and taken out of the work area
through the waste toadout unit.

Remove Confa/n/flflffltf (^Yaf (ft Polyethylene from Walls

The next cleaning task involves taking down the  exposed layer of polyethylene from the
walls. Ideally, the polyethylene is lighdy misted with an encapsulant or lock/down" material
to minimize the release of airborne  fibers when the  polyethylene is disturbed.  The
polyethylene is first detached from the floor polyethylene at the base of the  wall and then
detached from the inner wall  layer at the top of the wall.  To minimize the  generation of
fibers, the polyethylene is then  folded inward to form a  compact bundle for bagging and
disposal. Any visible debris which leaked behind the exposed layer of polyethylene onto
the remaining layer is now removed with a HEPA vacuum and/or wet wiping methods.

 Remove Contaminated Laver of Potvethviene from Floors
 Next, the contaminated layer of floor polyethylene is removed in the same manner as the
 waH layer, while shifting equipment around as necessary to access the floor layer.  Any
 visible contamination which leaked through the remaining layer must be removed.

 Apply Lockdoutn Material to Substrate

 Though the substrate may appear to be visually dean, very small amounts of ACM may
 have become lodged in  pores, cracks or crevices that were inaccesstole. A lockdown
 material  is applied to the substrate to control  and minimize the amount of asbestos fiber
 generation thai might result from  this residual contamination.   The lockdown should
 not be used as a substitute for good cleaning practices.

 A variety of products  are available for locking down the substrate.  These lockdown
 products are usually applied  as sprayed-on liquid type sealants (alternatives for certain
 situations are latex paint and concrete sealant). It is important to select a lockdown sealant
 that is compatible with  the substrate to ensure that adhesion occurs  between  the two
 surfaces.  Also, consideration  must be given to compatibility with the replacement material.
 Other factors in selecting the lockdown material include toxidty, volatility, fire ratings. For
 example, the selected lockdown material is considered by Underwriter  Laboratories (UL)
 to be a component of the flreproofing system. It must  be tested and found to be compatible
with the replacement material or the UL rating on the replacement material could be void.

 Lockdown materials are typically applied with airless  sprayers.  It is good practice to use
color tinting when applying lockdown materials to  ensure that all areas of the substrate

 have been covered.  One coat of locfcdown Is usually adequate to adhere any remaining
 fibers in place.  Additional coats may be warranted for cosmetic purposes,  and to be
 certain that all surfaces nave been coated.

 Remove Remaining Wan and FI         5 °f Polethylene
After the (ockdown material has been applied, the remaining layers of polyethylene on the
wafl and floor are removed and disposed of in the same manner as the first layers. Critical
barriers on windows, vents, etc. are left in  place.  If there is carpet in the work area
specified for removal, workers should lightly mist the entire carpet with amended water
before detaching it from the floor and rolling it up.  The carpet is then wrapped with 6- mil
polyethylene, sealed with duct tape and labeled for disposal.  If the carpet is not specified
for removal, at least one layer of polyethylene should remain in place to protect it from
contamination and damage.

Inspect and Clean Any Residual Debris

Once all layers of polyethylene have been removed (except critical barriers and floor poly
over carpet, if  necessary), the  area is closely inspected for any debris that may have
penetrated the final  layer of polyethylene.  Any debris found is removed with a HEPA
vacuum or wet-wiping technique to avoid recontaminating the area.

Wet Clean WaMs and Floors

The next activity is to HEPA vacuum and/or  wet clean walls and floors.  Workers begin
cleaning the areas farthest away from the negative air filtration units and use amended

 water to wet wipe all exposed surfaces except the substrate from which the ACM was
 removed. After the walls are wet wiped, the floor is mopped with a dean mop head using
 amended water.  The water is changed each time the mop is rinsed out and waste water
 from wet-cleaning activities Is dumped into the shower drain to be appropriately filtered or
 mixed with the removed ACM for cSsposal as asbestos contaminated waste.

 Wait Overnight - Repeat Wet-Wipe and Wet-Mop Procedures

 Because asbestos fibers can remain airborne for several hours once they are suspended
 into the air. a provision  for a "waiting period" between wet-cleaning procedures may
 improve cleanup.  The National  Institute of Building  Sciences (NIBS) Model Asbestos
 Abatement Guide Specification outlines a three-stage cleaning process.  Each cleaning
 procedure using rags and amended water or a HEPA vacuum is followed by a 24-hour
 period during which negative air filtration units remain running.

 This stage of the project is also a good time to change out HVAC filters that may be
 contaminated with asbestos dust.  The old filters should be wetted with amended water,
 removed and disposed of in the  same  manner as other asbestos-containing materials.
 Persons performing this task should wear respirators and protective clothing.  The owner
 normally installs the new filters at the end of the abatement project but this should be
 discussed and agreed upon during the initial planning of the project.

 Visual Irtsoaction/Recieafi H Ateoassa/v

The final visual Inspection Is conducted as a team approach  by the owner's
representative and contractor's representatives  after  the  work area surfaces

are  thoroughly dry.  All surfaces and ledges, tops of beams, and all other hidden
locations are  inspected for visual contamination at this time.   A standard method for
conducting visual inspections in asbestos abatement work areas has been developed by
the American  Society of Testing and Materials (ASTM).  It is important that the project
specifications  clearly delineate how the visual inspection wUI be conducted so that all
parties are aware of the criteria and methods which will be used.  Areas which need to be
cleaned are documented and addressed by the contractor. After recJeaning. the inspector
and contractor's representative make a final walk-through  to assure the items listed have
been addressed.

Final Clearance Monitoring

After the area  passes visual inspection, and the contractor gives notification that the work
area is ready for clearance testing, aggressive clearance air monitoring is performed by a
testing company retained by the building owner. Criteria, protocols and data interpretation
for clearance monitoring are addressed in Section IX. If the first set of clearance samples
indicate airborne fiber concentrations in the work area are above  the specified 'clearance
level," the area is recteaned folowed again by clearance sampling.  The project designer
may consider specifying that the contractor pay for any additional clearance sampling that
is conducted after the initial testing.

After the area has been cleared for reoccupancy by unprotected personnel, the  HEPA
filtration units are shut down, the critical barriers are removed and remaining renovation
can be initiated.

 The top layer of floor poly in the equipment room is removed at the same time the top layer
 of floor poly in the work area is removed, using  the same procedures.  This minimizes
 tracking contamination back into the work area. After cleanup is completed inside the work
 area, the polyethylene on the walls of the decontamination unit is lightly misted with
 amended water and folded inward.  Next the remaining layers on the floor are removed in
 the same manner and packaged with the other poly for disposal.  The walls are visually
 checked for contamination and wet wiped if necessary.  The decontamination unit can now
 be disassembled for transport

 WASTE DISPOSAL

 Waste Loadout Procedure

 The most effective method in a waste loadout procedure is to use two teams of workers: an
 inside team and an  outside team.  Wearing appropriate respirators and protective ckMhing,
 the inside team ensures that  the drums are properly packed, lids locked into  place and
 plastic bags removed from the outside of each drum before it is sent through  the waste
 loadout area and  into the enclosed truck.  (The plastic bags should then be placed in the
 next drum  for  disposal.)  It Is Important that no workers from  the Inside  team exit
the work area through the airlock.

 In cases where the drums are not being covered with plastic bags, the inside team assures
that each drum exiting the work area is free of any dust.  This may be accomplished by
inspecting and wet wiping every drum leaving the area

Wearing half-mask respirators and appropriate protective clothing, the outside team (In the
waste toadout area) posts themselves at the entrance to the work area  They receive the
drums into the toadout area from the inside team. Then, the outside team loads the drums
into the enclosed truck. Trucks must be posted with the NESHAP warning sign during
loading and  unloading of asbestos waste.  The  warning sign contains the following
wording:
                                    DANGER
                            ASBESTOS DUST HAZARD
                      CANCER AND LUNG DISEASE HAZARD
                            Authorized Personnel Only

The entrance into the waste loadout area from the work area is secured to prevent any
unauthorized entry or exit

Drums must be  placed on level surfaces in the enclosed truck and packed tightly together
to prevent shifting and tipping. Under no  circumstances should containers ever be thrown
into the truck. Also, when moving the containers, hand trucks, dollies or pull carts should
be used.

To assure that the truck is properly enclosed,  the inside or "bed" area  is lined with two
layers of 6-mil polyethylene. First, the floor is completely covered with a 12-inch overlap of
each piece. The same method is used to  property secure the sheets of polyethylene to the
sides and top of  the truck.   This  not only ensures additional enclosure of asbestos-
containing waste,  but it also provides for easier dean-up operations.  It  should be noted
here that any debris or residue observed on containers or surfaces outside the work area

 resulting from disposal activities should be immediately cleaned by using HEPA-fiHered
 vacuum equipment and/or wet wiping, as appropriate.

 Other Forms of Asbestos-Containing Waste

 In any asbestos abatement project, not all of the waste material that needs to be disposed
 of will be loose  or broken apart. There are many cases in which  it will be necessary to
 dispose of materials such as asbestos-containing floor, wall or ceiling tiles, shingles, rugs,
 dtemantled items, etc.  This may include neatly banding together tiles or shingles, with care
 not to expose sharp edges or any other protruding objects that could possibly puncture the
 polyethylene enclosure. Once the materials are banded together, each bundle is wrapped
 in two layers of 6-mil polyethylene, secured  by duct tape, and labeled appropriately.  When
 this is complete, the bundles are neatly stacked in the truck so that tipping or shifting of the
 load is prevented.

 Transportation To The AstjftfitQfj-ContaJnlna Waste Disposal Site

 As work progresses, and to prevent exceeding available storage capacity on site, sealed
 and labeled containers of asbestos-containing waste are removed and transported to the
 prearranged disposal location.   Regulations may vary from state to state, but there are
 standard procedures  that must be followed in  any operation  involving asbestos waste
 disposal.   The  National Emission  Standard for Hazardous air Pollutants (NESHAP)
requires vehicles that are used to transport asbestos-containing  waste material to be
placarded with an  asbestos warning sign  during the loading  and unloading of waste.
 Disposal must occur at an authorized site in accordance with regulatory requirements of

the U.S. Department of Transportation (DOT). NESHAP and applicable local guidelines, tt
is necessary to check with state officials on these requirements.
When transporting asbestos-containing waste to any disposal location, it is important that
the drivers of the vehicles be property trained In correct waste-handling procedures.  It is
also important that they not use excessive speeds or unusually rough roads to avoid load
slippage or tipping.  The driver will be responsible for retaining ail dump receipts, trip
tickets, transportation manifests, or other documentation of disposal.  These should then be
given to the building owner  for his/her records.   The waste  hauler  is responsible for
providing a copy of the NESHAP waste shipment record to the disposal site owners or
operators at the same time as the asbestos-containing waste material is delivered to the
disposal site.  The  Regulations section  provides additional  information about  waste
shipment records.
Once the asbestos-containing waste truck arrives at the landfll, the driver approaches the
disposal location as  closely as possible for  unloading  of  the waste materials.  The
asbestos-containing waste can be unloaded manually or by mechanical load dumping as
long as precautions are taken to prevent rupture of the impermeable containers.  In the
event a bag has been damaged, the material is repacked into another bag as appropriate.
The potential for rupture emphasizes the need to thoroughly wet the material before it is
placed in a disposal container.  It should be noted that the NESHAP requirement for *no
vistole emissions' applies to the landfill as well as the removal site.

 Personnel off-loading the containers should wear proper protective equipment which
 Includes disposable head, body and foot protection.  (Minimum respiratory protection
 requirements should include the use of half-face, air-purifying, dual-cartridge respirators
 equipped with high efficiency filters.)

 The NESHAP regulations require bags or drums to be placed intact in an excavated area
 and covered with a minimum of six inches of earth at the end of each working day.  These
 areas must be clearly marked to prevent future disturbance of the waste.

 Cleaning Up The Enclosed Truck

 During the last disposal trip to the landfill, after the truck has been emptied of all waste
 materials, the polyethylene lining the inside of the truck is misted with amended water and
 carefully removed. Good practice should include wet wiping the floor and walls of the truck
 at this time. Polyethylene removed from the truck interior and the protective dothing worn
 by workers conducting disposal are bagged  for disposal  and placed with the other
 materials at the dump site.

                 ABATEMENT  IN OCCUPIED  BUILDINGS
 INTRODUCTION

 Asbestos abatement procedures were initially developed for unoccupied, single-story
 structures typical of school facilities.  Some of trie earliest EPA guidance on asbestos-
 containing materials was directed specifically toward schools. These types of buildings
 offered many advantages to project designers  and contractors such as relatively simple
 building construction, extended shut-down periods and the ability to evacuate the building
 and inactivate HVAC and electrical systems.

 As the focus of asbestos abatement broadened to other types of commercial and industrial
 facilities, many of the containment and  removal techniques that were developed for
 schools needed to  be modified  to address more complex technical, architectural and
 logistical problems.

 In many structures, such as hospitals,  aviation facilities, and multitenant high-rise offices,
 the use of the  building precludes massive personnel relocation.  When the building must
 remain partially occupied, the ramifications of contaminating areas outside the work zone
 are potentially very expensive and time consuming from both technical and legal aspects.
 Although most projects do not involve extreme difficulties, there are many issues for
 consideration ranging from risk communication through procedural  decisions to economic
 evaluation.

 In the case of an occupied high-rise office building, contamination outside the work area
could require cleanup of several floors.  Extensive resources might be required to address

                                                                             Pjg»2
the issue of potential exposure to unprotected people working on those floors.  The same
would apply to hospitals where contamination outside the work areas could impose some
extremely complex public relations issues.

Abatement procedures in occupied buildings are not only impacted by the increased risk of
contaminating occupied areas, but also the nature of the structures and the  operations
within.  Asbestos  fireproofing was commonly spray applied on a variety of structural
surfaces within a building.  These areas include structural beams, decks, columns, and
shafts, with associated overspray onto adjoining surfaces, conduit, piping and  duct work.
Overspray inside duct work may also be an area of concern. These locations are often
difficult to access when removing the asbestos-containing material (ACM).  Electrical and
heating, ventilation and air conditioning (HVAC) systems may need to remain operational.
There are shafts and floor penetrations to worry about; transport of equipment, personnel
and waste disposal present logistical difficulties; critical or sensitive equipment may need
to remain operational; and  the  building maintenance staff  may  require  access  to
equipment in the work area while abatement is in progress.

This section covers some  of the common problems associated with asbestos removal in
occupied  and high-rise buildings  and outlines some of the factors to consider in the
respective design solutions.

FACTORS TO CONSIDER IN THE DESIGN PHASE

One  of the most critical concerns associated with  abatement in occupied buildings is the
potential for exposure to building occupants if there should be a breach in the containment

 barrier.  An added concern is entry, inadvertent or otherwise, by unauthorized personnel
 into the project area.  Monitoring can be conducted in the occupied areas to document
 airborne fiber concentration. However, by the time elevated levels are detected, the area
 and occupants within will have been exposed.  Prevention, by Including safeguards
 In  the abatement design and execution, Is the best  approach.

 The two primary  methods of confining fibers  to the  work area  are  construction  of
 containment barriers and use of HEPA-filtered air units  to create a pressure differential
 between the work area and  adjoining spaces.

 Containment Barriers - High-rise structures have features which are not typical In single-
 story buildings that make construction of the containment  barrier more difficult.  Floor
 penetrations for cable, pipe, shafts, and chases are generally present and wBI serve as a
 conduit for air and water if not sealed.  Also, many multistory buildings have a curtain wall
 construction which creates a perimeter space  that exists just inside the walls of the
 building. In this type of construction floor decks extend to within anywhere from a half inch
 to four inches of the exterior wall.  This space also needs  to be sealed or blocked off.
 Figure VI-1 demonstrates methods to contain a work area  having an exterior curtain wall.

 To  help reduce the risk of fiber migration in occupied buildings project designers  typically
 specify stricter methods of constructing and utilizing critical barriers than are used in empty
 buildings. Critical barriers as utilized on an asbestos abatement project are, as the name
suggests, essential or critical in  confining the elevated level of airborne asbestos fibers
generated during the removal process.  These  barriers are the last line of defense in
preventing the migration of ftoers into spaces direct/ adjacent to the removal work areas,
or more  importantly, in  preventing migration of fibers into any common air handling

system(s) with the potential of contaminating the entire building or significant portions
thereof.
These barriers, which, in single-story unoccupied buildings are often constructed of simple
wood frames with polyethylene sheets attached  and sealed, serve a similar, but much
more important purpose in taD or occupied facilities.  A much more complicated system of
engineering controls must be utilized in these structures.  Some of these methods include
the use of solid wood barriers over which polyethylene sheets are applied. Also a double
solid barrier may be constructed in extremely sensitive areas.  Caulk and fire stop foam
can be used to effectively seal slab penetrations during the abatement process. It may be
difficult to identify floor penetrations that are no longer being used and have been covered
up but not tightly sealed.

Where curtain walls are present, if the space between the slab and wall is narrow (less
than two inches), foam may typically be used to fill the gap.  For wider gaps it will probably
be more effective to construct the critical barrier using a material such  as rubber roofing
strips that wii lay snugly up against the side of the wall and extend over the gap out onto
the floor. The barrier is then covered with layers of polyethylene to form the containment.
Seals installed between floors will often have to be removed at the conclusion of the
abatement project.
       Number Of Air Changes. Higher Pressure Differential - As an additional safety
measure for removal  projects in occupied buildings, the number of air changes per
hour may be Increased to as much as  ten or even twenty In  contrast to the
traditional  minimum  of  four  which  Is  relied  on  In  most  single-story
unoccupied projects.   With the  controlled  flow of make-up air, this number of air

 changes within a totally enclosed, sealed off work area typically produces a differential
 ranging from 0.05 to 0.1 inches water gauge in the air pressure between inside the work
 area and outside the work area.  As discussed in Section V. this Increased differential is
 necessary  to overcome changes in environmental conditions.  High-rise buildings are also
 known to commonly produce a stack effect of air flowing upward which can create strong
 pressure imbalances on opposite sides of an  enclosure.   Additionally. HVAC systems
 which remain operational outside the work area may interfere with the negative pressure
 being maintained in the work area.

 This pressure differential, while working effectively to help contain contamination within the
 work area, also contributes to the need for added reinforcement when erecting critical
 barriers and enclosures around the work area.  Polyethylene must be affixed to the walls
 much more securely than  is required under decreased pressure differential conditions.
 Sprayable coatings may be required to help withstand the pressure differential.  Another
 problem of using HEPA-filtered exhaust units in  multistory, occupied buildings is obtaining
 locations for venting the exhaust to the outside.  Windows may have to be removed and
 replaced with wooden  templates  to  accommodate the  exhaust ducts.   Additional
 precautions must be implemented when removing windows at heights well  above street
 level to avoid injury to those below.

Once the project  begins,  the HEPA-filtered exhaust units will remain in continuous
operation.  The decision to require back-up power for these units will depend on site-
specific conditions  such as the likelihood of  power interruption and the likelihood of
contamination  outside the work area should power be lost.

    Monitoring - While the single most reliable method of assuring barrier integrity is visual
inspection of barriers on  a regular basis  during  a project, air monitoring is usually
conducted around the perimeter as an additional means of documentation.  Presently, two
methods for analysis of these air samples are available:  phase contrast microscopy (PCM)
and transmission  electron microscopy (JEM). PCM analysis, if performed on site, can give
a quick indication of fiber concentration around the perimeter of the work area.  However,
PCM analysis can be misleading.  This analytical  method calls for the microscopist to
include all fibers,  within certain size limitations, to be reported on any particular sample.  It
does not count or detect  fibers that are less than 5 microns long or 0.25 microns diameter.
It does not differentiate between  asbestos fibers and other fibers such as carbon fliers,
mineral wool or glass fibers. This problem is especially evident when asbestos removal
takes place in conjunction with other normal construction activities.  TEM analysis, while
giving positive identification of asbestos fibers, cannot give immediate results on those
samples.  Consequently, any results of TEM analysis would be significantly after the fact
and posstoly too late to give warning or Indication of breaches of the enclosures.

Another method  sometimes used for testing the effectiveness  of  critical barriers and
enclosures is the fibrous aerosol monitor (FAM).  This apparatus can run continuously and
give a near real time approximate readout of fiber concentrations within the ambient air
around an  active  work site.  The FAM also relies  on PCM-type technology and.
accordingly, can provide  misleading information.  Another problem is the lag time of many
hours required for the FAM to register accurate low-fiber concentrations in the 0.01 -0.05
f/cc range.

To summarize, the selection of the most appropriate monitoring method wPI be influenced
by site-specific factors such as ongoing construction outside the abatement project and

 project designer may need to consult with an industrial hygienist to determine the best
 method for the given site.

 Systems Running Through Work Areas Mav Need To Remain Operational

 In an occupied building, there may be systems running through the work area that cannot
 be shut down. Two common examples include the HVAC system and electrical bus ducts.
 There may also be critical or sensitive equipment located in the work area that must remain
 operational or cannot be removed.

 HVAC Issues - H Is always preferable to shut down the HVAC  system,  secure
 the work area and seal  the openings. A prepxoject evaluation and cost estimate will
 need to be conducted to determine if it is feasible to inactivate the HVAC or whether it must
 remain operational. Factors to consider include the configuration and zoning of the HVAC
 system, local dimatic conditions, length of anticipated down time, scope of the  project,
 stationary equipment  which might  require cooling,  and building  codes.   Another
 consideration would include the possibility of installing  localized temporary HVAC.

 If  the HVAC must remain  operational during removal, very stringent engineering,
 monitoring and  administrative measures are required.  One of the main concerns in
 keeping the HVAC operational and uncontaminated Is to maintain positive pressure in all
duct work, plenums and serviced occupied areas with respect to the abatement work area.
Adjustments must be  made, if necessary, to the mechanical system to produce a  positive
static pressure within the air handling system.  This modification Is comparable to blowing
up a balloon where the exhaust to the outside is restricted and air is forced into the system

(i.e., the "balloon") by the operation of the supply fan.  The project designer may need to
enlist the help of a mechanical  engineer to develop procedures for pressurizing the
system.  Some of the general considerations are discussed below and Figure VI-2 is a
schematic diagram of this method.

One of the key issues is whether the HVAC system can operate on fresh air or whether
return air needs to be entrained via mixing dampers.  This need will be influenced by the
temperature of the outside air and the capacity of the HVAC system fans.  The colder the
weather, the greater the need for return air.

Where return air is required, it is  essential to make sure dampers  are adjusted and
operating property.  This may involve the installation of temporary adjustable dampers or
the addition of a manual control  system to existing dampers.  Where return air is not
necessary, mixing dampers can be temporarily sealed off with polyethylene and duct tape
to ensure air tightness.

Once the mixing dampers have been properly adjusted or sealed, the joints in the duct
work are seated with duct tape and the duct work is endosed in two layers of polyethylene.
The return fan is shut down and exhaust dampers are sealed, typically with  plywood and
caulking.

After the HVAC modification and adjustments have been made, a pressure monitoring
system needs to be established.   This  can be done by  installing rigid, leak-free  static
pressure tape with manometer, mechanical or electronic displays or automatic monitoring
instruments in the supply and return duct work.  Readings  from  these locations can be
compared to  a static line installed in the work area to determine the negative pressure

condition  relative to the duct work.  The return fan casing Is the most critical area for
monitoring.  If positive pressure is maintained here, the entire system is positive.
The system should be tested once it has been adjusted and pressure monitors have been
installed.  This test should be conducted once the negative pressure is established in the
work area, but before actual asbestos abatement begins.  The supply fan switch can be
turned to the manual "on" position. All seals on duct work should be checked with a smoke
tube and if return dampers are in use they can be further adjusted as necessary to achieve
the desired pressurization.

Air  sampling  should  be   conducted  at strategic points to  ensure  and
document the HVAC  system  Is not  becoming contaminated  with  asbestos
fibers. It may be desirable to collect a background settled dust sample from inside the
duct work  prior  to starting the system to make a qualitative determination about the
presence of asbestos in dust  Air sampling locations  should be selected in downstream

such as offices.  Air flow patterns could be checked with  a smoke tube to determine the
best location  for placing air samples.  Background air samples should be collected at
these locations prior to removal and analyzed by the same techniques that would be used
for analyzing samples collected during removal.

In some projects, the use of a  fibrous  aerosol  monitor may be appropriate.   It has the
advantage  of providing a  near real time reading, and  can be  used as an effective
surveillance tool. Inside the work area, the RAM is effective in detecting rapid increases in
the airborne concentration.  This indicates the need for more stringent work practices. As

 mentioned earlier it has the disadvantage of not distinguishing fiber types and being a
 relatively expensive instrument (~$10.000~$13.000).
 Operating Stationary Equipment - In addition to the HVAC system, other concerns inside
 the work area include items such as energized electrical bus ducts carrying high voltage
 electrical wiring for the entire building, cable trays, transformers, and other equipment that
 must  remain  operational and  needs  ventilation.    It  Is   reemphaslzed  that

 preferred procedure prior to asbestos  removal.  If  this is not possible, then certain
 precautions and employee training are necessary. Dry removal  may be required.  Dry
 removal typically requires permission from regulatory agencies.  Ft may be possible to wrap
 conduit or ducts in polyethylene or rubber sheeting.  Another alternative is to  build an
 enclosure around  the equipment.  A portable air conditioning  unit might be  used in
 conjunction with negative air units to supply cool air to the equipment and evacuate warm
 air. These  alternative  approaches are site-specific and require extreme  care
 In design and  Implementation.

 VERTICAL SHAFTS

There are several  significant concerns associated with  performing abatement in tall or
occupied buildings which have existing interior vertical shafts. These include:

       1.     Cross contamination of occupied floors through vertical shafts;
      2.     Preexisting contamination  within elevator  shafts due to vibration  and air
             turbulence within the shafts;

       3.     Vacuum  and venturi effects wittiin elevator shafts  due to the piston-like
              motion of elevator cabs;
       4.     Proper methods of sealing off work areas located adjacent to, around or
              within shafts;
       5.     Effective  methods of relieving positive pressure within elevator shafts when
              relief ports are sealed or obstructed due to abatement work within the shafts.

Interior vertical shafts within tall  or occupied buildings have presented unique problems
during asbestos projects since removal work in  these structures first began.   Interior
vertical shafts are present in nearly all tall buildings.  These shafts are utilized most often
for elevators and numerous utility systems serving the building (i.e., electrical, plumbing,
and particularly ventilation systems).   Vertical shafts  are often  used for ducting  and
distributing  conditioned air throughout the building.  Furthermore, shafts  may be used
frequently for other purposes such as bathroom exhausts, dumbwaiters, mail drops and
trash chutes.

The purpose of vertical shafts within a structure is  to  make the  building's utilities  and
services available to aH  occupants in all spaces. Unfortunately, this efficient distribution of
building service can contribute to the problems associated with performing abatement in
these facilities.  As these services are distributed to the different levels of the building,
many voids are  created  in the  shaft walls at each level.   The  pipes, ducts, conduit.
horizontal shafts, etc. run  through the voids in the shaft walls and large volumes of air can
also pass through the wals around these service items.  The problem stems from the
vertical shafts traversing through occupied floors  and abatement work area floors alike.
providing a conduit for contamination  generated during the removal process to migrate to
occupied areas of the  facility.  This problem  is aggravated  and magnified by elevator

                                                                              Pago 14
 movement within a shaft.  The piston-like  movement of the elevator cab can  cause a
 vacuum or venturi effect and actually pull contaminated air into the shaft and distribute that
 contamination throughout the building.  A "stack effect*, or upward movement of air. can
 also occur in tall vertical shafts.

 Ideally, the solution to this problem would be to completely shut down all elevators which
 are in  shafts that penetrate  floors where asbestos  abatement  work area  is  being
 performed.  Realistically,  this would be impractical, due to the need to move occupants
 throughout the building.  Also, the elevators in high-rise buildings are often utilized to
 transport  abatement workers,  supplies and  packaged asbestos waste during a  removal
 project.  Due to the necessity  to keep some elevators and shafts in use during a project
 and the difficulty ensuring that all openings to a shaft are completely sealed, the potential
 for contamination on occupied floors adjacent to work area floors is real  and must be
 considered in the abatement design.  In some cases, it may be necessary to construct an
 exterior elevator for use by the  asbestos abatement contractor.

 Elevators that are not needed  for transporting personnel, equipment and asbestos waste
 from the work area should  be locked out so that they do not stop on floors where removal is
 taking place.  Critical barriers can then be constructed to isolate the elevator openings from
 the work area.

 One method of  isolation  involves sealing the elevator opening In the work area with
 polyethylene and plywood or gypsum board  and caulking.  Some situations may warrant
the need to form an air space at the elevator doors and pressurize the space with HEPA-
 fitered air so that it is at a pressure greater than that of the elevator shaft  The seal can be
constructed by first covering the elevator door with polyethylene and duct tape.  Then a

barrier constructed of gypsum board and metal studs or ptywood and wood studs can be
placed a minimum of three inches from the face of the door.  A small containment area is
formed between the barrier and door with 6-mil polyethylene and duct tape and the space
is pressurized with a ducted exhaust from a HEPA-filtered unit located outside the work
area.

In situations where the elevator must be used to transport workers into the work area, the
decontamination unit is usually constructed so that it adjoins the elevator. Provisions must
be made so that air is not drawn back through the decontamination  unit into the elevator
cab or shaft.  One design solution is to place a hard door between the dean room and the
airlock leading into  the shower.  The door would remain  closed whenever the elevator
doors were open.

Another problem that may need to be addressed in the abatement design is preexisting
contamination within an elevator shaft due to vixation and air turbulence caused by the
operation of the elevator.  These forces may have, over the years (typically 10-20 years),
dislodged ACM located within the shafts.  This situation is usually associated with friable,
sprayed-appJied materials used  for fireproofing.  Review of the building survey or  a
preproject evaluation of the elevator shafts should be conducted to  determine if there  is
asbestos-containing  fireproofing on exposed beams inside the shafts and if there is visual
contamination at the bottom of the shafts.  Prior to initiating removal  on any of the floors.
any visible debris at the base of the shafts should be removed  with a HEPA vacuum.

Another challenge regarding vertical shafts in tall, occupied buildings is  conducting
abatement within the shafts. Containment  of the work areas is of great significance within
an occupied  building because improper containment may  lead to significant airborne

 contamination. This contamination can migrate throughout a facility via shafts which pass
 through occupied areas.

 Once a work area involving an elevator shaft is sealed and enclosed, the enclosure may
 present another complication.  Relief ports which vent positive pressure from the shaft may
 be obstructed.  In many cases, elevators will fail to operate if the pressure relief ports are
 blocked. In other situations, air from within the elevator shaft will be forced out of the shaft
 through small openings, such as at doors which have not been completely sealed. Again,
 the potential for asbestos contamination is significant.

 If an entire shaft is being abated, typically the elevator will be locked out on each floor and
 doors will be sealed off by erecting  plywood and polyethylene on the shaft side of the
 doors. The floor and walls of the elevator pit will be predeaned and lined  with layers of 6-
 mil polyethylene and the cables will  be isolated where possible with polyethylene.  The
 method for accessing the material will be site specific  depending on the  configuration of
 the elevator shaft.  Single shafts are sometimes accessed by using the tops of the cabs as
 a working surface.  In shafts that accommodate more than one elevator, workers with safety
 lines attached will sometimes access the ACM from seats connected to cables in the shaft.
 Because of the numerous safety issues associated with  removing ACM from
 the  Inside of elevator shafts, the project designer may need to rely  on the
 expertise  of  a safety engineer when  developing the abatement  specification.

asbestos removal project and is addressed in the Safety Considerations section of this
notebook, there are some  issues, such as maintaining operation of the sprinklers and
alarms, that are of even greater importance in occupied, tall buildings.

Fire Suppression Systems

The requirements for maintaining operational sprinkler systems inside the asbestos
abatement  area will vary depending on  state and local  codes.   It  is generally
recommended that  the sprinkler system remain operational or at least be  only shut off
during work activity. Care  must be taken not to obstruct sprinkler heads in a way that
would keep them from being effective.

If  the sprinkler  system is  not deactivated  there must be appropriate provisions  for
emergency shutott and water runoff in case the system is activated by something  other
than  a  fire.   One such  example would occur from someone inadvertently hitting and
knocking off a sprinkler head with a rolling  scaffold, ladder or other equipment  One
solution is to require a protective device such as a cage to be  installed around  each
exposed sprinkler head in  the work area.  Additionally, the contractor should have a
response plan posted which indicates the location of the shutoff  valve for  the sprinkler
system and workers  should be trained to respond to a major water leak.

Because of the potential for water to penetrate  floors below  and  spread asbestos
contamination, it is critical to keep water confined to the abatement  area.  Bags of
absorbent, squeegees and mops should be kept on site for dealing  with large quantities of
water.

                                                                              Pago 18
 Smoke detectors and alarms may also be affected by abatement activities.  For example,
 some  smoke detectors are triggered by the opacity of light.  Dust will act  like smoke  in
 reducing the amount of light and trigger the alarm.  Also, most smoke detectors and tire
 alarms in buildings  are now required  by  code to have  a back-up  power supply.  As a
 precaution, the back-up supply should be tested before beginning abatement

 Attention should also be directed toward the presence and locations of fire doors.   Fire
 doors are often magnetized and activated by an electronic-type fusible link. If a fire occurs,
 the doors are triggered and automatically shut. Care should be taken not to interfere with
 the functioning  of the  fire  doors by obstructing  them with construction materials or by
 propping them open.

 One other preproject consideration  is to determine  if a halon fire suppression system Is
 being used within the project area.  Though it is  a remote possbility, if the halon system
 were activated in a small enclosed area, the oxygen could be dangerously depleted.

 Equipment and Materials

 A common safety measure built into  the project design is the requirement for the contractor
 to have fire extinguishers on site which have been tested and tagged within the last year.
 The general  rule of thumb is one  extinguisher for each 2,500 square feet of floor space. In
 addition to the pressurized-water (2.5-gallon) fire extinguishers, which are typically used, a
dry chemical fire extinguisher may  be  needed on site if stationary  electrical equipment
 must remain operational.

 As specifications are being developed, project designers will need to carefully review local
 and state fire codes.  Some codes for tall, occupied buildings stipulate that abatement
 cannot be conducted on two contiguous floors and that there must be at least five buffer
 floors between each floor where asbestos removal is taking place.

 WATER LEAKS TO FLOORS BELOW ABATEMENT PROJECT

 Besides the potential for a major water leak from damage to the sprinkler system, the water
 used inside the work area for wetting the ACM and showers is also of concern.  Water
 damage Is one of the most  common Insurance  claims on  abatement projects.

 The designer may require the contractor to take special precautions with showers and
 hose. For example, a sump-pump-type drainage system can be placed below the showers
 and aluminum pans placed under them to drain water to prevent a  leakage problem.  The
 designer may require the contractor to use time-controlled valves that automatically open
 and dose in concert with working  hours so workers can leave the project area without
 leaving  behind live water lines.   At a  minimum, procedures  should be In place
 which assure water Is turned off at the end of each shift  This may require the
 water shut-off be  located outside  the work area.  Specifications  may also require the
 contractor to use copper tubing instead of rubber hoses to hard plumb high pressure water
 lines.

 LOGISTICAL CONSIDERATIONS AND PUBLIC RELATIONS

There are several logistical considerations associated with asbestos  removal in  tall.
occupied buildings that are often  not encountered with  single-story  structures that are not

occupied. Since some of these considerations are closely tied to public relations issues.
The discussion below addresses both.

Inconvenience of Removal Activity

It is difficult to conduct an abatement project in an occupied building without posing some
inconvenience to the building occupants.  Measures which can be used to lessen the
impact of contractor personnel and equipment on site include:  a public relations effort to
Inform building occupants of the removal activity, establish at least a one-floor buffer zone
above and below the project area, work night shifts only, and phase  the work to
correspond with periods of lowest occupancy.

Experience  indicates that  projects typically  go  much  more  smoothly  when
affected building occupants  have  been  Informed.  A program for informing the
building occupants about the nature of the project  and  the engineering  controls and
monitoring  that are being  implemented should be completed  shortly after the  project
specifications are developed.  The proper means of informing the building occupants will
vary in each building and may range from a written notice to a meeting.  The information
should include key elements such as why the removal project is being conducted, where it
is being conducted, who is performing  the work, who is monitoring the work, what the
safety procedures  and engineering controls are, how long the project will take and  who
occupants should contact if they perceive there is a problem.  This information is  usually
developed  by building management in conjunction  with legal counsel.  The project
designer may be needed to help address specific questions from building occupants as
they relate to the specifications.

                                                                              Papa 22
 If it is feasible (in some locales it is mandatory), there should be at least one unoccupied
 floor above and below the abatement project (i.e., three floors total).  This not only provides
 a buffer zone In case there are inadvertent contamination leaks, but it also provides
 storage for the contractor's equipment and materials, and helps reduce noise transmission
 from the project area to the occupied spaces. Buffer floors also accelerate the project time
 line allowing the work crew to prepare the  next abatement area while removal is being
 completed on the adjacent floor.

 Another way to minimize the effects of the removal activity is to have the contractor's crew
 work night and weekend shifts.  This may or may not add extra expense to the project and
 may alleviate problems for the contractor such as parking and maneuvering equipment in
 congested areas during  weekdays.  There  may also be foreseeable periods during the
 year when building occupancy is expected to be lower such as major holidays or at the
 end of lease periods. Conducting abatement projects during these periods  would affect
 fewer building occupants.

 Transport of Personnel. Equipment and Asbestos Waste

An often-overlooked  but critical issue with respect to scheduling is the  transport  of
personnel, equipment and asbestos waste.  In many buildings there is a freight elevator
which can be designated for use by the contractor.  As long as the elevator remains  in
good working order, this is usually the best means of transport.  It is more difficult in those
buildings where a freight elevator does not access all floors.  Typically, one of the elevators
utilized by building occupants must then be designated for use by the contractor's crew.  It
is often  best to require in the design specifications that asbestos waste be removed from

the project area after normal business hours. This reduces visibility, chance of exposure to
building occupants and is usually more convenient for the abatement crew.

Emergency Response Program

In addition to the emergency response program which has been discussed for fire safety,
there is also a need for contingency plans in the event of power failure, elevator problems,
shutdowns of negative pressure systems,  water  leaks, personnel injuries and natural
events such  as earthquakes or tornadoes. The contractor  should  be required to
develop and submit  these prior  to project startup.

SUMMARY

On a given project conducted in  a tall or occupied building there may be several additional
concerns not discussed in this section.  With  some of the concepts presented here in mind,
the project designer will need to carefully evaluate the building and communicate with
building management to fine tune the site-specific issues that are critical to the success of
the project

PROTECTION OF  ASBESTOS  ABATEMENT  PROJECT PERSONNEL
INTRODUCTION

Most asbestos abatement projects require the direct disturbance of asbestos-containing
materials, or the dust and debris  derived from  these materials.  Studies have
repeatedly  demonstrated  that  these  activities  almost always  result  In
significantly  elevated  airborne   asbestos  concentrations.   The  actual
concentration will  vary depending on the friability of the material, amount and type of
asbestos Involved, control measures employed, number of workers involved, volume of the
work area, and work practices  used.  When designing the asbestos abatement project all
of these factors are considered to minimize the generation of airborne asbestos fibers.
Such factors include wet cleaning methods and the use of local exhaust ventilation. These
are termed engineering controls.  Engineering controls are employed to reduce  the
airborne asbestos concentration to the lowest feasible amount  Respirators and other
personal protective equipment are then used to  further reduce exposure to the
asbestos abatement workers.  Personal protective  equipment  (e.g.,  respirators)
must not be considered a substitute for effective engineering controls.

Toxic substances include any material which can damage biological tissue.  However, for
a toxic substance to be hazardous  (I.e.. pose a risk), exposure must occur at the site where
damage is likely.  Toxic substances can enter the body in three ways:  (1) through  the
gastrointestinal tract, usually via  the mouth; (2) through the skin; and (3) through the
respiratory system.  Asbestos  fibers are not believed to pose a significant health threat
through ingestjon or skin exposure. They can. however, pose a  significant risk if inhaled
into the respiratory system.   Other chemicals which may be present in an asbestos

 abatement work area may have different routes of entry for which protection may be
 necessary.

 RESPIRATORY SYSTEM

 The respiratory system is a gaseous (air) pump consisting of a series of airways leading
 from the nose and mouth down into the air sacs (alveoli) of the lung itself.  Within the
 alveoli, oxygen  and carbon  dioxide are  exchanged.  Trie main components of  the
 respiratory system, from top to bottom are fisted below.
       •  Nose and mouth
       •  Throat
       •  Larynx (voice box)
       •  Trachea (wind pipe)
       •  Bronchi (branches from the trachea)
       •  Bronchioles (smaller air passageways)
       •  Alveoli (terminal air sacs in the lung)
       •  Diaphragm and chest muscles

 RESPIRATORY HAZARDS

 Respiratory hazards are generally divided into two categories:  toxic contaminants and
oxygen  deficiency.   Generally, asbestos abatement projects do  not  pose oxygen
deficiency hazards. However, since there are projects and circumstances where it can be
a problem, oxygen deficiency must always be considered. For example, there could be an
oxygen deficiency problem while performing  abatement in steam tunnels, mechanical

chases or boilers.  Failing to consider oxygen deficiency could result in a fatality on a
project
The normal concentration of oxygen  in air is 21 percent.  NIOSH defines an  oxygen
deficient atmosphere as below 19.5 percent oxygen at sea level. A concentration of 19.5
percent provides an adequate amount  of oxygen for most work assignments and includes
a safety factor. The safety factor is included because oxygen deficient atmospheres offer
little warning of the clanger.  When oxygen concentrations fall below 16 percent, decreased
mental  effectiveness, visual  acuity, and muscular coordination  occur.  When  oxygen
concentrations fall below 10  percent, loss  of consciousness may occur, and below
6 percent, death will result.

Toxic contaminants are a more common category of respiratory hazards encountered on
abatement projects.  These toxic contaminants are generally divided into two categories:
paniculate and gaseous materials (or a combination of the two). Asbestos fibers are an
example of the paniculate category and carbon monoxide is an example of the gaseous
category.  It is possible to have both of these hazardous substances, as well as others such
as organic vapors, in a work area at the same time.

The control of respiratory hazards typically involves three steps:
      •  Assessing the hazards
      •  Reducing or eliminating the hazards
      •  Providing respiratory protective equipment

The asbestos  abatement  project  designer should  assess  existing  hazards
known  to be present  In the Intended work area and  anticipate  others that are

 likely to arise during the project  For example, airborne asbestos fibers should be
 anticipated for any asbestos removal project.  Organic vapors might also be anticipated
 from spray adhesives or floor tile mastic remover, and if surfaces are to be painted after the
 removal project.  Through a well-designed project, some of the respiratory hazards can be
 eliminated or reduced.  For example, an electric heater rather than a propane heater will
 eliminate  the  possibility  of  carbon  monoxide  in the work  area from  the propane
 combustion. Since it is usually not feasible to engineer out all hazards, workers and others
 at the job site must be  made aware of possible hazardous conditions.  Lastly, respiratory
 protection will almost always be specified on asbestos abatement projects.   The type of
 respirator chosen for use is critical to assure that adequate protection is provided.

 CATEGORIES OF RESPIRATORS

 There are two broad categories of  respirators.  These are air purifying and  supplied air
 respirators. in each category there are many different types of respirators (i.e., powered air
 purifying, gas masks,  pressure demand supplied air respirators, etc.).  Many of the
 respirators available are not appropriate for protection against asbestos since they are
 designed for a specific contaminant, such as chlorine gas.

 Air Purifying Respirators

These respirators remove the hazardous contaminant from the breathing air before it is
inhaled.  They consist of a soft rubber faceptece and a replaceable filter or cartridge.  Two
major subcategories of air purifying respirators are the mechanical filter type and the
chemical cartridge type.  The mechanical filter variety  is designed to protect against
paniculate contaminants such as asbestos. The chemical cartridge type protects against

gaseous contaminants such as solvent vapors. Each respirator assembly is approved for a
particular contaminant; care must be  taken in choosing the appropriate  unit.  High
efficiency filters designed for asbestos are typically  purple or magenta in color (Figure VII-
1). These fitters are designed to remove 99.97 percent of the particles 0.3 micrometers or
greater in diameter.

Air purifying respirators remove limited concentrations of air contaminants from the
breathing air, but do nothing to improve (of change)  the oxygen content Thus, they can
only be used in atmospheres where there is enough oxygen and where air contaminants
do not exceed the specified range of the respirator and cartridge.  Often, however, this is
adequate protection when propping the asbestos abatement work area, performing final
cleanup  (wipe downs), or during gkwebag removal projects.  During gross removal and
gross cleanup, a different category of respirator may be used to provide greater protection
for the worker; the supplied air respirator

Air purifying respirators are further categorized based on their degree of face coverage.
The half mask respirator (Figure VII-2) covers half the face; from the bridge of the nose
to  under the chin. A full face respirator (Figure VII-3) covers the face from the forehead
to  under the chin.  The more extensive coverage provides a better fit and a higher degree
of  protection.

Some air purifying respirators depend upon inhaling by the workers to draw atmospheric
air through the respirator filter of cartridge where it is  decontaminated.   Hence,  they are
referred to as negative pressure respirators.

Powered Air Purifying Respirators (PAPRs)
Another subcategory of air purifying respirator is the powered air purifying  respirator
(PAPR) shown in Figure VIM.  It uses similar types of cartridges and filters as negative
pressure  air purifying  respirators to clean  the air.   PAPRs.  however, are  positive
pressure devices which employ a portable, rechargeable battery pack and blower to
force contaminated air through a filter or cartridge where it is  filtered and supplied to the
wearer's breathing zone.  PAPRs are available in both tight-fitting and loose-fitting
styles.  A tight-fitting respirator relies on  a tight fit of the facemask to seal to the face.
Loose-fitting respirators include hoods and helmets and must  be positive pressure types.
An advantage of using a powered air purifying respirator is that it supplies air at a positive
pressure within the faceptece. helmet, or hood so that arty leak is usually outward.

Supplied Air Respirators

Supplied air respirators are used in conjunction with an airline to provide breathing air
from a  source outside the work area.  This  type of respirator is often  referred to as  a
Type C or airline respirator.   Supplied air  respirators are further divided  into several
categories described below.

Demand  Tvoa Airline Respirators - These respirators provide air to the worker only when
the worker inhales.  Accordingly, they are not considered positive pressure respirators.
Demand respirators  are onty available  as tight-fitting respirators with  a half or full
facepiece.

 Continuous Flow Airline Respirators - These respirators provide a  constant flow of
 breathing air to the worker at a rate of at least four or six cubic feet per minute (CFM).  Four
 CFM is necessary for tight-fitting respirators and  six CFM for loose-fitting types.  The
 minimum airflow requirements are intended to provide air to the worker faster than his
 breathing rate. They may be half mask or full facepiece respirators, helmets or hoods, and
 be tight fitting or loose fitting to the face.

 Pfessure Demand Type Airline Respirators - These respirators have a regulator which
 maintains a constant positive pressure within the facepiece.  Accordingly, it is very difficult
 for a worker to breathe at a rate faster than the incoming air. Pressure demand respirators
 are only available in tight-fitting models with a half or full facepiece.

 Regardless of which type of supplied air respirator is used, the breathing air must meet
 minimum specifications required by the Occupational Safety  and Health Administration
 (OSHA) Respiratory Protection  Standard (29 CFR 1910.134).  The minimum allowable
 specification is caHed Qrada D breathing air.

 Grade D breathing air is the minimum quality for use in suppled-air respirators.  The grade
 D breathing air specifications are established by the Compressed Gas Association  and
 incorporated into the OSHA respirator standard by reference. Table VII-1 summarizes the
 requirements for grade 0 air.

One problem with supplied air  respirators is the possible loss of air supply while inside the
work area.  The OSHA regulations require  that  a backup air  supply be available in the
event of compressor shutdown.   However, this does not provide any safeguard against
loss of air if the airline is severed or disconnected.  For this reason, the National Institute for

Occupational Safety and Health (NIOSH) recommends that a backup be available on the
worker. This may take the form of a backup short-term air supply  bottle, or more
commonly a backup high efficiency filter to be used in the event of air loss (Figure VII-

The self contained breathing apparatus, or SCBA, Is another form of supplied air respirator
(Figure VII-6). The SCBA system does not rely on an airline but incorporates an air tank
carried by the worker, such as those used by fire fighters.  The SCBA will normally provide
30  minutes to an hour of breathing air, making it unsuitable for asbestos abatement
workers.  However, it  is sometimes used by project designers and inspectors since it
permits  the individual access to areas beyond the reach of airlines.  The SCBA is only
available as a tight-fitting respirator operated in the demand or pressure demand mode.

 USE OF APPROVED RESPIRATORS AND COMPONENTS
 Any respirator used on an asbestos abatement project must be approved.  The federal
 agencies that approve respirators are the National Institute for Occupational Safety and
 Health (NIOSH) and the  Mine Safety and Health Administration  (MSHA).  The approval
 label should accompany each respirator when purchased. At the top of the approval label
 will be listed contaminants for which the respirator is approved or in what atmosphere the
 respirator may be used.  The approval label will also list limitations for that specific make
 and model of respirator.  NIOSH publishes annually a list of all approved respirators In a
 publication titled NIOSH  Certified Equipment List.

An individual make and model respirator may have more than one approval depending on
which fitter element is Installed.  For example, one type of full face air purifying respirator
may be approved for asbestos fibers when the high efficiency filters are installed, and also
be approved for organic vapors when the organic vapor cartridges are installed.  The
approval number for each respirator is always preceded by the letters 1C* which stands
for tested and certified.'

The approval remains valid as long  as  the  respirator contains all its original parts or
replacement parts from the same manufacturer intended for the specific make and model
of respirator. For example. H a headstrap is broken and replaced with a headstrap from a
different manufacturer, the approval is no longer valid.  For air supplied respirators, the
approval includes the airline  and  regulator as well.  Accordingly, respirators of one
manufacturer cannot be connected to  the airline of another manufacturer. In most cases,
each manufacturer uses a slightly different connecting mechanism to prevent this from
occurring.

PROTECTION FACTORS

No respirator totally  eliminates exposure to  airborne contaminants.  However,
some respirators provide greater protection than others.  In order to compare the protection
provided by different respirators it is necessary to understand the concept of protection
ffldois* A protection factor is an index of the degree of protection afforded by a particular
category of respirator. The protection factor is determined by measuring the concentration
of a contaminant inside and  outside the respirator simultaneously.  By dividing  the
concentration measured outside the respirator by the concentration measured inside the
respirator, the protection factor is obtained. Technically the term  is fit factor; however, In

confusion, the term protection factor will continue to be used here.  The term protection

                  Concentration inside the respirator
The higher the PF number the greater the protection afforded by the respirator. The lowest
number possbte is 1 since this would mean the concentration of the airborne contaminant
is the  same inside and  outside the respirator.  A protection factor of 10 indicates the
respirator will reduce the concentration of the airborne contaminant by a factor of 10. Put
another way, the concentration of the contaminant inside the respirator will not exceed
1/1 Oth the concentration outside the respirator, assuming a proper fit of the respirator to the
face.

Research is continuously conducted to determine the protection factors of new respirators
and Improved versions of older models.  Accordingly, the number assigned to a particular
class of respirators may  change based on new information.  For example, the protection
factors referenced in the 1986 OSHA asbestos standard (29 CFR 1926.58) were quickly
out of date when NIOSH  published the latest PF values a year later.  While the OSHA PF
values remain the legal minimum, designers may wish to apply for more current NIOSH PF
values. The most current PF values are listed in  Table VII-2 along  with a suggested
maximum use concentration for each category of respirator.

The protection factor  depends greatly on the fit of the mask to the wearer's
face.  Accordingly, the protection offered by any one respirator will be different for each
Individual person.  Further, the protection  constantly changes depending upon the
worker's activities and  even shaving habits.   When a worker laughs or coughs  inside a
respirator, the protection factor will decrease since the mask will not fit as well during

RESPIRATOR FIT TESTING

The assigned protection factor can only be assured if the respirator fits properly.  Individual
workers have different facial features that make fit testing necessary. The OSHA asbestos
standard  (29 CFR 1926.58)  and the OSHA respiratory protection  standard (29 CFR
1910.134) both require that employers fittest each employee when a negative pressure
respirator is issued.   Fit testing is  not  required to be performed for positive pressure
respirators  unless there is a possibility that the respirator will  be  used in a negative
pressure mode.  For example, a tight-fitting powered air purifying respirator may lose its
battery charge and only operate as  a negative pressure respirator.  In  this instance the
respirator should be fit tested with the battery disconnected to simulate this occurrence.

Fit testing is required when the respirator is first issued and every six months thereafter.
The reason  for continued fit testing is due to the possibility that a worker may have gained
or lost sufficient weight to change facial size and affecting the respirator fit. Initial fit testing
will need to  be repeated whenever an employee changes the make, model or size of
his/her respirator. At the time of initial fit testing, the employer must have available at least
five sizes of respirators from at least two manufacturers. For example, trus would include
sizes small,  medium, and large from manufacturer A; and sizes small/medium and
medium/large from manufacturer B. Under the provisions of the OSHA asbestos standard,
employees retain  the right to request  a powered  air purifying respirator in  lieu of a negative
pressure respirator. It is the employer's duty to provide the PAPR upon request without
cost to the employee.

 The  weak  link  In  respiratory  protection  Is the seal of the respirator  to the
 face.  Anything that interferes with the facial seal wfll reduce the protection provided.  It is
 for this reason thai chewing gum and tobacco are not permitted when respirators are worn.
 For tight-fitting respirators there should be no facial hair along the line of contact between
 the respirator and the face. Individuals wearing respirators requiring a tight seal to the face
 should be clean shaven.  Mustaches and short sideburns are usualy permitted since they
 do not interfere with the facial seal. Temple bars on glasses will interfere with the seal in
 full facepiece respirators.  Most manufacturers oner eyeglass inserts for their respirators
 which allow prescription lenses to  be worn inside the respirator. For many years OSHA
 prohibited the wearing of contact  lenses inside a full facepiece respirator.  In light of a
 recent study, OSHA has lifted the  prohibition on gas permeable and soft contact lenses.
 OSHA  is considering issues surrounding hard  contact lenses but currently still prohibits
 their use inside full facepiece respirators.

 There are two categories of fit testing that can  be  performed  for negative pressure
 respirators.  They are the qualitative fit test and the quantitative fit test.  The qualitative fit
 test is a pass/fail test used to determine the fit of respirators having an assigned protection
 factor of 10 or less.  This simple type of test is designed to determine if there is more than
 10 percent leakage around the facepiece. Quantitative fit testing is used to measure the fit
of the  respirator wtth each worker by measuring the concentration inside and outside the
respirator with a test substance.

Qualitative Fit Testing

During fit testing, the respirator straps must be property adjusted in accordance with the
manufacturer's directions and should be as comfortable as possible.  Overtightening the

straps wiU sometimes reduce facepiece leakage, but trie wearer may be unable to tolerate
the respirator for any length of time. The facepiece should not press into the face and shut
off Wood circulation or cause major discomfort. At the time of respirator selection, a visual
inspection of the fit should always be made by a second person.

Once a  respirator  has been selected and  no visual leaks  are evident, a negative
pressure check and positive pressure check are performed  by the wearer.  These
simple procedures are described below.

Negative Pressure Respirator - For this check, the wearer closes off the inlet of the filters or
cartridges by covering them with the  palms of the hands or by squeezing  the breathing
tube so that air cannot pass through,  inhales so that the facepiece collapses slightly, and
holds his/her breath for about ten seconds.  If the facepiece remains slightly  collapsed and
no inward leakage of  air is detected, the respirator passes the  test. This test can only be
used on respirators with tight-fitting  facepleces.   Its potential drawback is that hand
pressure can modify the facepiece  seal and cause false results.

Positive  Pressure Respirator Check  - This check is similar in principle to the negative
pressure check.  It  is conducted by closing off the exhalation  valve of the respirator and
gently exhaling into the facepiece. The respirator fit is considered passing if moderate
positive pressure can be built up inside the facepiece without evidence of outward air
leakage around the facepiece.

If the respirator selected fails to  pass these simple checks, the fit  testing  should not
proceed further.  Instead, another size or another brand should be  donned and these tests
repeated. Alternatively, it may only be necessary to adjust the straps on the  respirator and

 repeat the tests.  Once the wearer has successfully passed the negative and positive
 pressure fit checks, the actual fit test may be conducted.  The OSHA standards permit
 qualitative fit testing for half  mask air purifying respirators.  Quantitative fit testing is
 required for full face air purifying respirators.

 The actual qualitative fit-test method chosen is at the discretion of the employer as long as
 it is one of the three specified in Appendix C of the OSHA asbestos standards (29 CFR
 1910.1001 or 29 CFR  1926.58).  The procedures must follow those in this appendix
 whether Irritant smoke, Isoamyl acetate, or saccharin is chosen as the test agent
 The irritant smoke test is summarized below.

 Irritant Smoke Test - H the previous tests have been passed, the irritant smoke test may be
 administered.  It can be used for both air purifying and supplied air respirators when  used
 in a negative pressure mode (i.e. high efficiency backup filter).  However, an air purifying
 respirator must have high efficiency filters. The test substance is an irritant smoke. Sealed
 glass or plastic tubes with substances to generate this smoke are available from safety
 supply companies.  When the tube ends are broken and air passed through them with a
 squeeze bub, a dense irritating smoke is emitted.

 For the test the respirator wearer enters a test enclosure (a dear suspended plastic bag is
sufficient) and the irritant smoke is sprayed/squeezed into a small hole punched in the bag
near the respirator wearer's head.  The wearer is asked to perform a series of exercises
including head turning, jogging in place and speaking as specified in Appendix C of the
OSHA asbestos standard (29 CFR 1926.58).

Quantitative Fit Testing
Quantitative fit testing provides an actual measure of the fit of a particular make and model
of respirator for each individual. Historically, this was performed using a test chamber filled
with a test atmosphere such as com oil, mineral oil or sodium chloride.  A specially outfitted
respirator which aOowed for sampling the air inside the mask was worn by the worker. The
air inside and outside the respirator was sampled and analyzed to determine the percent
leakage around the facepiece.  More recently, test devices have become avaflabte which
will measure the concentration of particles inside and outside  the respirator on the actual
respirator used by the worker.  Regardless of which method is used, an actual protection
factor is determined for each Individual for each respirator issued.  Since the quantitative fit
test is more sensitive, it is capable of measuring protection  factors higher than 10.  If the
measured protection factor  exceeds 10  times the  assigned protection  factor for  the
category of respirator being tested, only the assigned value times  10 may be used.
Accordingly, the highest protection factor possfcte for a half mask air purifying respirator is
100; and for a full facepiece air purifying respirator is 500.

TYPICAL RESPIRATOR USE DURING ASBESTOS RESPONSE ACTIONS

Table VII-2 can be used to select which respirator is appropriate for the asbestos-related
activity  if the  airborne  asbestos  fiber concentration can  be reasonably predicted.
According to OSHA,  H  historical data are not  available to accurately predict what  the
worker's  exposure will be on an asbestos abatement project the workers must wear air
suppled  respirators until personal sampling results are available which will allow the level
of protection to be downgraded.  Historical air  sampling data must include personal air

 abated, number of employees, and employees' level of training.  OSHA has also stated
 that air supplied respirator usage must be resumed if conditions at the job site change that
 would be reasonably expected to  result in a significant increase in worker exposures to
 airborne asbestos.  For example,  the removal of acoustical plaster from the celling  of a
 school is expected to  take two months.  Workers are expected to wear air supplied
 respirators (if no historical data is  available) until personal air samples demonstrate  that
 the control methods are effective in  reducing  exposures to a level where less protective
 respirators would be allowed.  The workers may use the less protective respirators  until
 conditions at the job site change, such as when an area of acoustical plaster to be
 removed  has a heavy  coat of paint preventing  effective wetting of the material to be
 removed. At this point the workers would have to go back to using the more protective air
 supplied respirators.  The process of evaluating the personal exposure samples  is then
 repeated.

 OSHA also permits personal air sampling to be waived if air supplied respirators are worn
 by the workers, for example,  on short (one- to two-day) projects.  The rationale is the
 project will be over by the time results of the personal air monitoring samples are available
 to be evaluated.

As a rule of thumb, air purifying respirators are usually used during minor repair activities;
glovebag removal projects; during  preparation of a work area where asbestos-containing
dust debris or material will be disturbed; for use during asbestos waste loading and
unloading; and during final cleaning activities at the conclusion of an asbestos abatement
project. Air supplied and, more particularly, pressure demand air supplied respirators may
be used during gross removal and gross dean -up activities.

RESPIRATORY PROTECTION PROGRAM

Any employer who  requires or permits employees to wear a respirator  must
have a written respiratory protection program. This is required by OS HA in both of
their asbestos standards and their respiratory protection standard (29 CFR 1910.134). The
written respirator program establishes standard operating procedures concerning the use
and maintenance of respiratory equipment  In addition to having such a written program,
the employer must also be able to demonstrate that the program is  enforced and updated
as necessary.

The OSHA regulations spell out what must be included in a written program. Those items
are discussed below with special emphasis on applications to work performed by asbestos
abatement personnel.

An effective resp^ator program, as adapted from A Guide to Respiratory Protection for Ihe
Asbestos  Abatement  Industry.  USEPA/NIOSH publication  EPA-560-OPTS-86-001
(September 1986). should include:

      1.     A written statement of company policy, including assignment of individual
             responsibility, accountability, and  authority for required activities of the
             respiratory protection program.

      2.     Written standard operating procedures governing the selection and use  of
             respirators.

       3.     Respirator selection (from NIOSH/MSHA approved and certified models) on
             the basis of hazards to which the worker is exposed.
       4.     Medical examinations of workers to determine whether or not they may be
             assigned an activity where negative pressure respiratory protection is
             required.

       5.     Employee training in the proper use and limitations of respirators as well as
             a way to evaluate the skill and knowledge obtained by the  worker through
             training.

       6.     Respirator fit testing.

       7.     Regular cleaning and disinfecting of respirators.

       8.     Routine inspection of respirators during cleaning, and at least once a month
             and after each use for those respirators designed for emergency use.

       9.     Storage of respirators in convenient dean and sanitary locations.

       10.    Surveillance of work area conditions and degree  of employee exposure
             (e.g.. through air monitoring).

       11.    Regular Inspection and evaluation of  the continued effectiveness of  the
             program.

All of the above Items are required by OSHA if employees wear respirators during work.
            a Policy
Every  employer should prepare a dear concise policy regarding the use of respirators by
their employees when performing asbestos abatement activities for asbestos.  This policy
should serve as the guiding principal for the preparation, implementation, and enforcement
of an effective respiratory protection program.

Designation of a Program Administrator

A respiratory protection program administrator must be designated by name. This
person  is responsible for implementation of, and adherence  to, the provisions of  the
respiratory protection program. It is usually a  good idea to also designate a person who is
responsible for enforcement of the procedures at each  job site.  Procedures should also be
outlined for enforcement of the program.  Enforcement procedures  and the development of
the program as a whole should be done in conjunction  with, and input from, the employees
and/or their representatives.

Sel&ction and Use of Respiriitnrv Protection Equipment

Respirators used shall be selected from those approved by the Mine Safety and Health
Administration (MSHA)  and the National Institute for Occupational Safety and  Health
(NIOSH) for use in atmospheres containing asbestos fibers. A NIOSH-approved respirator
contains the following:   an  assigned identification number associated with each  unit; a
label identifying the type of hazard  for which the  respirator is designed, additional

by a qualified individual to ensure that the employee understands the limitations, use. and
maintenance of respirator equipment

Paspir^tor Fit Tasting

One of the most Important elements of an effective respirator program is fit testing. The
OSHA asbestos standard (29 CFR 1910.1001 and 1926.58) and the OSHA  respirator
standard (29 CFR 1910.134) require  that the  fit of respirators be determined  when the
respirator is issued and every six months thereafter for all negative pressure respirators.
Procedures for fit testing should be  addressed  in the written respirator program.   A
discussion of fit testing is  induded elsewhere in this section.

Cleaning and Disinfection of Respirators

Whenever feasible, a respirator  should be reserved  for the exdusive use  of a single
individual.  Following  each use, the respirator should be cleaned  and disinfected. The
following procedures can  be  used to dean a respirator

      •  Wash with  a detergent or a combination  detergent and disinfectant, in warm
         water using a brush.

      •  Rinse in dean water, or rinse once with a disinfectant and once with dean water.
         The dean water rinse is particularly  important because  traces of detergent or
         disinfectant  left  on  the mask can cause skin  irritation and/or damage  respirator
         components.

         not dry misshapened.  Respirators should not be hung  by the rubber facepiece
         and equipment/supplies should not be stacked on top of  respirators.
Routine Inspection
Inspection of the respirator is an important, routine task. H should be performed by the user
before and after each use. The following items should be checked, at a minimum.

Air Purifying Respirators (half mask and full facepiece} - Rubber facepiece should be
checked for:
       •  Excessive dirt
       •  Cracks, tears, or holes
       •  Distortion from improper storage
       •  Cracked, scratched or loose-fitting lens
       •  Broken or missing  mounting clips

Headstraps should be checked for
       •  Breaks or tears
       • Loss of elasticity
       • Broken or malfunctioning buckles or attachments
       • Excessively  worn serrations of the  head  harness  which might  allow the
         facepiece to slip

Repair
At some point any respirator will need replacement parts or some other repair.  OSHA
requires that the person who repairs respirators be trained and qualified.  It is important to
realize that respirator parts from different manufacturers are not interchangeable.  NIOSH
approval is invaidated if parts are substituted

Respirator Storsps

Proper storage is very important  The law requires that respirators be protected from dust,
sunlight, heat, extreme cold, excessive  moisture, and damaging  or contaminating
chemicals.  When not in use, the respirator should be stored  in a clean, convenient.
sanitary location.

Surveillance of Working Conditions

The employer must provide adequate surveillance of the employee's working conditions to
be certain the respirator selected provides adequate protection.  In the case of asbestos
abatement, this includes a determination if other hazardous airborne contaminants, such
as resilient flooring mastic remover or encapsulant might  be encountered for which the
respirator chosen  is not adequate.   The surveillance also  includes air monitoring  to
estimate the asbestos exposure. This provides the needed information to determine if the
respirator chosen affords sufficient protection to the individual.

 Resoirator Proaram Evaluation and Rocordko&oina
 The respirator program shall be evaluated at least annually with program adjustments, as
 appropriate, made to reflect air sampling or other evaluation results.  Compliance to the
 aforementioned points of the program should be reviewed; respirator selection; purchase
 of approved equipment; medical screening of employees; fit testing; issuance of equipment
 and associated maintenance; storage, repair and inspection; appropriate surveillance of
 work area conditions.

 Attention should be given to proper recordkeeping. Records which should be kept include
 names of employees trained in respirator use. documentation of the care and maintenance
 of respirators, medical reports of each respirator user, possible airborne concentrations of
 asbestos fibers during work* and any problems encountered during projects with regards
 to respiratory equipment  A cneckist for self evaluation of a respiratory protection program
 is included at the conclusion of this section.

 PROTECTIVE CLOTHING AND OTHER PROTECTIVE EQUIPMENT

The primary  reason  that protective  clothing is worn by  the workers is to keep gross
amounts of asbestos-containing dust and debris  off the body, out of the hair, and from
beneath fingernails.  The combined use  of protective clothing  and  proper
decontamination  procedures  will  greatly  reduce  the  amount  of asbestos
taken out of the  work area.  Protective clothing will also reduce the chance of rashes
and discomfort caused by the material being removed. In addition to asbestos, frequently
these materials contain fibrous glass, mineral wool, and binders such as Portland  cement.

Each of these materials can be skin irritants. Reports In the literature have also found that
workers with prolonged contact with asbestos may develop asbestos "warts".

Protective clothing on asbestos abatement projects consists of coveralls, foot covering,
head covering, and gloves.  Ideally, the foot and head coverings should be attached to
the coveralls.  This eliminates the need to tape  the openings between the garments. Tight-
fitting bathing suits are often worn beneath the coveralls. Nylon suits work well as they are
easily rinsed off in the shower.

The protective clothing most often  used  is of a disposable type.  However, nondisposable
protective clothing is sometimes used on large projects.  When nondisposable doming is
used It is most often laundered inside the work area.  Wastewater is drained to a holding
tank and filtered along with the shower water; or it may be used to wet asbestos-containing
materials.  The dryer exhaust may be ducted to  an inlet of a HEPA-filtered local exhaust
unit to remove the hot air from the work area. If an outside laundry is used, stringent OSHA
regulations must be followed  regarding packaging, labeling, notification,  etc.   The
remainder  of this section, particularly  instructions on donning protective clothing  and
disrobing, pertain to the use of disposable protective clothing.

Protective dothing does not include street clothes, T-shirts, blue jeans, sweat bands, knee
pads and socks.  If any of these items are used inside the work area, they  must remain
there until the job is completed and disposed of as asbestos-contaminated waste unless
laundered as described above. Jewelry, such as  rings and watches, should not be worn in
the work area.

 Other protective dotting/items such as hard hats, gloves, and safety shoes/boots should
 remain in the work area for the duration of the project  Upon project completion, items that
 cannot be cleaned may be placed  in a plastic bag, labeled as containing asbestos, and
 taken to the next project If safety shoesAxxrts are not used,  it is wise to have workers wear
 some form of proper foot protection with nonskid sotes. These  remain In the work area and
 are disposed of at the end of the project as asbestos-containing waste.  It is a good idea to
 have each worker mark his or her boots  and hard hat with  his/her name with permanent
 ink,

 To summarize, listed below are items normally worn by asbestos abatement workers.
       •  Disposable coveralls, disposable foot covering, disposable head covering
       •  Nylon swim suit
       •  One-piece rubber steel-toed safety boots, or other  shoes with nonskkd rubber
          soles
       •  Hard hat (as required )
       •  Gloves (cotton, or as required for the work performed)
       •  Eye protection (not necessary if  full facepelce respirators are used)

The disposable coveralls, foot, and  head  coverings are available from many sources and
of several materials.  Good quality coveralls, with foot and head covering attached, usually
cost about  $3.00 each when purchased In quantity.  Separately,  the coveralls cost
approximately $2.00, head covering about $0.35, and foot covering about $0.50 per pair. It
is important to realize that many  "bargain' prices may not be  a bargain  at al.  The less
expensive coveralls often use  less material.  Accordingly, coverals marked "XL" may be
too small  for many workers. Be sure to check the construction of the coveralls as well.
Double stitching on seams wll last longer,  but cost more.

Under the provisions of the OSHA asbestos standard (29 CFR 1926.58) the contractor
(employer) must have a "competent person' on site.  One of the duties of the competent
person is to routinely inspect the integrity of the protective clothing worn by the asbestos
abatement workers. Severely torn clothing should be replaced. Small rips or tears may be
repaired with duct tape.

A common problem on asbestos abatement projects is a failure by contractors to purchase
enough coveralls for the project Each worker must use a new coverall (and foot and head
covering  if not attached) each time he/she enters the work area.  Assuming two breaks and
a lunch  period, four coveralls will be needed each day by each worker.   Additional
coverafts are usually needed for authorized visitors (architect industrial hygienlst, etc.) and
to replace some that are torn to the point  of being unusable.  As a rule of thumb, the
contractor may estimate the number of suits needed to a project by the following formula.

       5  x number of workers x project duration (days)« number of coveralls needed

As an example, a project lasting 46 days using a crew of 8 workers and 1 job foreman wil
need the following  number of coveralls (estimated).

       5x9 people x48 days = 2,160 coveralls

Accordingly, the contractor should order 87 cases (25 per  case) of coveralls for the project
The  prudent contractor would purchase 100 cases to allow for sufficient surplus. When
purchasing coveralls, large and extra large sizes should be purchased. These can always
be made  to fit smaller employees.

PUTTING PROTECTIVE CLOTHING ON
Protective dothing Is put on in the dean room of the decontamination unit before entering
the work area. The following sequence should be used.

       1.     All street dothes,  including  undergarments are removed and stoned in a
             dean,  convenient location.  Bins or lockers work well for this. It is usually
             wise to have a lockbox or  other means  to protect valuables.  This will
             discourage employees from bringing wallets, rings, keys, etc. into the work
             area.

       2.     The nylon swim suit is put on.

       3.     The disposable coveralls are put on.

       4.     If separate disposable foot coverings are used, these are put on.

       5.     Ankles are taped to  take up slack in  the suits and  reduce  the  chance of
             tripping, (tape pants over foot coverings, if separate).

       6.     The respiratory equipment is inspected, put on, and fit checked.

       7.     The hood or head covering is put on over the respirator head straps.

       8.     Worker passes through  airlocks  and shower to contaminated equipment
             room.

       9.     Boots are put on over the disposable foot coverings (or safety shoes, as
             required).

       10.    Gloves are put on (cotton gloves are usually worn although leather gloves
             should be used for handling metal lath).  The sleeves are taped  over the
             gloves using duct tape.

       11.    Other protective equipment such as hard hats and safety glasses (H a half-
             face respirator is used) are put on.

One person should remain outside the work area at all times.   It should be his/her
responsibility to ensure that each person entering the work area has the proper protective
clothing.

Once inside the work area, no employees, or others, should be permitted to leave without
going through the decontamination sequence unless it is an extreme  emergency.  A
common problem is employees "stepping our for a drink of water or supervisors 'stepping
In' the work area to deliver a message or piece of equipment.  These activities defeat the
purpose of the protective equipment and the decontamination sequence.

TAKING PROTECTIVE CLOTHING OFF

Whenever an employee or other person leaves a work area for any reason, he/she must
go through the decontamination sequence.  This sequence should include the following
steps.

              asbestos-contaminated material.  All disposable clothing should be placed
              in plastic bags inside a drum and labeled as asbestos-containing waste.

       2.     The person  should then dean reusable protective equipment such  as
              boots/shoes, safety glasses, hard hats, etc.

       3.     The person  should then  proceed to the  shower still  wearing  his/her
              respirator.  While showering, the person should be sure to wash his/herself
              and his/her respirator.  Used respirator cartridges may then be discarded in
              a plastic bag located at the shower.  When using a PAPR. be sure to follow
              the manufacturer's instructions to protect the motor and battery pack from
              water damage.

       4.     The person should then proceed to the clean room; dry off; dress in his/her
              street clothes; and disinfect, dean, and inspect his/her respirator.

Asbestos abatement projects  are frequently conducted in boiler rooms or  other areas
where heat stress may be a concern.  The wearing of fun-body protective dothing can
reduce the cooling capacity of the body since evaporative cooling is reduced.  Disposable
protective dothing is available in "breathable" and "nonbreathable" varieties.  A
breathable fabric will reduce the symptoms of heat stress in hot environments and provide
for greater worker comfort  It should be noted, however, that some fabrics are so thin
(almost transparent) that  its  protective  value  has been questioned.   The asbestos

FOR FURTHER INFORMATION

The USEPA and NIOSH jointly prepared and published a document titled, A Guide to
Respiratory Protection for the Asbestos Abatement Industry (Publication EPA-560-OPTS-
86-001, September 1986 revision), which provides valuable  information concerning the
use and Imitations of respirators on asbestos abatement projects.  A checklist from this
publication has been  reproduced at the end of this section.  The asbestos abatement
project designer should be familiar with the requirements of the OSHA asbestos standard
(29 CFR 1926.58) and the OSHA respiratory protection standard (29 CFR 1910.134).  The
latest versions of these regulations are Included in the appendices of this notebook.

Some state,  county and municipal regulations may have  additional, more stringent
requirements  affecting  worker protection on asbestos abatement projects.  These
regulations should be reviewed when designing the project since they frequently change.

RESPIRATOR PROGRAM CHECKLIST

In general, the respirator program should be evaluated at least annually with program
adjustments, as appropriate, made to reflect the evaluation results.  Program function can
be separated into administration and operation.

                        SAFETY  CONSIDERATIONS
INTRODUCTION

Effective safety management begins in the planning stages of the abatement project.
Experience indicates that It is less costly and more efficient to prevent hazards rather than
react to accidents or incidents. Though the abatement contractor te directly responst>ie for
the safety and health of the worker, the designer can incorporate many safety features into
the specifications that will assure a smoother and safer project

The project designer must first be aware of the potential hazards that are associated with
an asbestos removal project. Once the hazards are identified. then measures can  be
specified where possible to eliminate the hazards by redesign or substitution of equipment
or procedures that are unsafe. If the hazard cannot be eliminated, the next approach is to
reduce tt by isolating it, guarding against it. or diluting rt.  To protect against hazards that
cannot be eliminated or reduced, the design specifications  must then require  the use of
specific protective equipment, work practices and/or related safety training.

The procedures used in a typical abatement project, such as sealing the work area, using
wet methods, working at heights on ladders and scaffolding, and shutting down building
systems, add new dimensions to the task of providing a safe working  environment.  This
section  will identify  and address various hazards associated with these tasks including
electrical shock,  falls from  scaffolding,  ladders, walking  and working surfaces, fire,
emergency procedures, heat-related disorders, carbon monoxide poisoning, and the need
for body protection and hazard communication. The effort spent to incorporate these safety
considerations into the project design is as important  to the success of the project as the

 effort spent in designing engineering controls to confine and minimize fibers in the work
 site.
 The project designer should indude a clause in the specification requiring the contractor to
 notify the building owner's representative when a hazard is identified. The contractor is
 required to take appropriate corrective actions to protect the asbestos abatement workers.
 Contractors should also be required to  comply with the OSHA general construction safety
 regulations, specifically requiring a 'competent person* [29 CFR 1926.32(f)] be on site, and
 the need for an accident prevention program [29 CFR 1026.20{b) (2)].

 ELECTRICAL SAFETY

 Electrical shock Is  one of the most common hazards, and one  that  gives the
 least warning.  Incorrect wiring, improper grounding, and lack of proper  shielding results
 in over  1,000 workers each year being electrocuted nationwide.  Many of these fatalities
 result from contact with just 120 volts alternating current (a.c.).

Three factors determine the severity of electrical shock. These are:
       • The amount of current flowing through the body,
       • The path of the current flowing through the body,
       • The time the current is allowed to flow through the body.

These factors vary greatty.  The path of the current depends upon the points  of contact
Most often the path is from the hands, through the body, and out the feet  The amount of
electrical resistance determines,  in part, the amount of current flow.   Moist skin or damp
conditions greatly reduce electrical resistance and  significantly increase a person's risk of

serious injury if he comes in contact with a current source.  In addition to the obvious shock
potential, many deaths result from falls after a nonfatal electrical shock.
During the design phase, potential electrical hazards to the workers should be identified
and, where possible, eliminated or, at a minimum, guarded or isolated. The more common
hazards are discussed below.

Identification of Wiring Faults In the Buffeting

Wiring faults in the building include open ground paths, reverse wiring polarity, and hot
neutral wires.  These common faults can easily be identified with a volt/ohm meter or with
plug-in type circuit testers and should be  corrected prior to project  startup. This  is
particularly important if these circuits wil be  used to provide power inside the work area.
Any wiring faults identified should be corrected by a qualified electrician prior to their use.

Uninsulated or Exposed Energized Wiring or Equipment

Asbestos  removal projects are often part of renovation or remodeling projects. Overhead
lighting is usually removed for cleaning.  Equipment or machinery may have been moved
out of the area before the removal job with wiring left in place.  Damaged equipment or
electrical fixtures  may need to be repaired. All of these things create potential sources  of
contact with the energized electrical circuits.  When possible, the project designer should
require that circuits that win not be used during removal efforts be turned off and locked
out.  Wiring  and   electrical  connections  should  always  be  considered
energized  until  tested  and proven otherwise.  Unenclosed wiring junctions in

 overhead areas should be addressed by the project designer since these are a particularly
 likely point of contact for removal workers.

 Asb&stos Abatement Protect Where the Building Remains Occupied

 Electrical circuits or service panels that are located inside the removal  area and that
 service other parts of the building can present a challenge to the project designer. Sealing
 transformers or control boxes may not be possible due to heat buildup. If this situation is
 encountered, an alternative design will need to be developed  which will allow for air
 circulation around these units.  Dry removal may be necessary to avoid a potential serious
 shock exposure.  Additionally,  where this situation  is encountered, all  breakers and
 switches must be clearly labeled in case power must be secured to other areas of the
 buflding during the removal project When  a dry removal is necessary, approval by local
 NESHAP authorities is necessary to avoid citation  for falure  to use wet  methods.  An
 alternative written plan must be submitted  by the contractor to NESHAP authorities for
 conducting the removal

 Providing Power to the Wor^Area

 Providing power to the work area can create hazards not normally associated with building
 systems.  Since OSHA considers abatement projects subject to the construction industry
 safety and health standard (29 CFR 1 926). there are special requirements for supplying
 temporary power to extension cords, portable electrical tools, electric air sampling pumps,
 electric equipment, and portable electrical appliances.  This may be done by supplying
power through  ground fault circuit  interrupters (GFCI1 or having  an assured equipment
grounding program in effect

An assured equipment grounding conductor program requires regular inspection (usually
monthly or more often if needed) of all tools, cords, and electrical devices with written
documentation maintained (29 CFR 1926.404(b)j.  Since it is very difficult to document
compliance with an assured equipment grounding conductor program, it is best to require
the use of GFCIs.  The required use of GFCIs to protect circuits provides the safest and
most feasible  power source available since  any significant current leakage will trip the
circuit (see Figure VIII-1). These devices prove most effective when placed as  near as
possible to the "toad" and kept out of areas of high humidity.  However, high-quality
commercially avaBabte GFCIs are  now on the market that work in both high- and low-
humidity environments.
        on Abatement Projects
Common electrical devices on abatement projects that present potential hazards and need
to be addressed in the project specifications are lights, HEPA vacuum cleaners, negative
air systems, drills, saws, heaters, sump pumps and, often, radios.  All of these should be
inspected regularly for damage, proper grounding, and integrity of insulation.

When possible, nonmetalic tools should be specified for vacuuming or scraping to prevent
a possfcte shock if wiring is cut or contact is made with energized equipment  Specifying
insulated handles on metal scrapers is another option.  Hard rubber or plastic scrapers,
while more difficult to find, perform well for removal.  Wooden or fiberglass ladders reduce
or eliminate a ground path if a worker contacts an energized circuit. Wiring should be
elevated, when feasbte, to keep it away from water on the floor, to avoid damage from foot
traffic and scaffolds, and to keep it from being a trip hazard.

When designing plans to reduce or eliminate electrical hazards, the project designer
needs to make sure that the plan complies with OSHA's lockout/tagout standard (29 CFR
1910.147). This standard requires that all potential sources of energy, whether liquid, gas,
electrical, or mechanical operations, be locked by the person performing the work, and that
person is the only  one with the keys to unlock the device.  Additionally, a tag must be
attached to serve as a warning sign or label to other workers in the area. If energy sources
are required to be disconnected by the contractor, the project specifications must require
the contractor to follow proper lockout/tagout procedures.

SCAFFOLDING SAFETY

Most asbestos abatement projects wifl involve the use of scaffolding. Proper setup, regular
inspection, and basic maintenance should not be overlooked.  In many removal projects,
manually-propelled mobfle scaffolding provides  a convenient and efficient work platform.
OSHA standard 29 CFR 1926.451 requires that when free-standing mobile scaffolding is
used, the height shall not exceed four times the minimum base dimension (usually the
width).  This  requirement is based on the fact that scaffolding easily tips.  Figure VIII-2
ilustrates a simple method to estimate a reasonable amount of force  necessary to tip a
scaffold.

Since relatively little force is required to tip a scaffold, it becomes important to make sure
that wheels on mobile scaffolds move freely, are lubricated and are  in good repair.  If
rented scaffolding is used, all components must  be inspected prior to accepting it  All
components such as  cross bracing, railings,  pin  connectors, planking or scaffold-grade
lumber must be available before the units are assembled.  Workers should be careful to
keep debris bagged and  obstacles off the floor where mobile scaffolds will be used.  If a

Guard rails (42 inches in  height) should always  be installed on scaffolding  used for
abatement projects. Workers are usually looking up while working and  can easily step off
the edge  of an unprotected scaffold.   OSHA requires that guard  rails  be used when
scaffolding is over 4 feet tall and is less than 45 inches wide. Any time scaffolding is 10
feet or higher, toe boards must also be in place.  No guard rails are  required when
scaffolding is less than four feet taU, although it is a good recommendation.

Additionally, scaffolding must, at a minimum, meet the following requirements:

       •  When guard rails are required, midrails (21 inches high) are also  necessary.

       •  Upright  supports should be positioned at intervals  no greater than eight feet
         apart.

       •  If, due  to the  configuration  of the work area, people  must  routinely  pass
         underneath the scaffolding, then a screen (number 18 gauge  wire one-half inch
         mesh or equivalent) is required from toe board to midrail.

      •  The scaffolding must be designed to support four times the maximum load that
         will be placed on the scaffolding.

       • Planking used on a scaffolding must be scaffold-grade lumber and extend past
         the sides by at least 6 inches but less than 12 inches, unless it is secured to the
         frame.

       • Scaffolding must be equipped with a ladder to reach the working platform.

As with the other areas of hazard identification and accident prevention, when there is a
need for scaffolding, the project design should specify the use of required devices and do
so in the safest manner possfote.

LADDER SAFETY

Ladders, as well as scaffolding, are some of the most commonly used pieces of equipment
on an asbestos removal site.  To assist the project designer, the following list of  ladder
safety rules or hazard-elimination ideas are presented.  These ideas should be considered
when developing plans to incorporate safety into the project design.

      •  Ladders with broken, missing or defective parts are prohbtted.

      •  Ladder feet must be on a substantial base.

      •  Work area at top and bottom of ladder must be kept dear.

      •  No job-made ladders are allowed.

       •  Metal ladders are prohibited near electrical equipment and Dnes (within 10 feet).
         Wood or fiberglass ladders should be selected to avoid electrical hazards.
         Ladders shall be used at pitch of four to one (one foot out for every four feet of
         elevation) or secured to prevent displacement during use.

         Ladders shall not be  used In a horizontal position as  scaffolding, platform or
         walkboard.

         Only one  person per ladder  is allowed and the person must always face the
         ladder when going up or down.

         An attendant is required in high-traffic areas.

         A worker  must not climb higher than the third rung from the top on a straight
         ladder or the second step from the top on stepladders.

         Wood ladders shall not be painted.

WALKING AND WORKING SURFACES

The National Safety Council estimates that there are over 250,000 disabling injuries in
work-related falls each year.  Over 40 percent of the injured workers are employed in the
construction industry.  Reducing the potential for slips, trips, and falls is a challenge in work
areas that are sealed with polyethylene and kept damp to reduce airborne fibers. This
results in very slick surfaces.  Disposable  booties are a potential trip hazard; air and
electrical cables also create trip hazards.  All of these conditions create potential worker
hazards even before removal begins.

Some of these walking and working surface hazards can be eliminated by using the
following guidelines:

      •  When designing a project consider the height of the work to be done, equipment
         to be used, and possible trip hazards.  Inspect the walking and working surfaces.

      •  The use of disposable booties may be impractical in many removal situations.
         They may come apart and create a serious trip  hazard. Seamless rubber boots,
         slip-on shoes or safety shoes with nonskid soles may be worn over the booties,
         or in place of the booties.
         Require the contractor to minimize water on floors.  Wet polyethylene is very slick
         and water increases the risk of electrical shock.

       •  Develop designs calling  for placement of airlines and electrical  cords in
         positions that do not cause them to run across travehvays. When possible have
         these Ines and cords suspended off the walking and working surfaces.

       •  Require that debris be minimized on floors by continuous cleaning.

       •  Require the  contractor to keep equipment, tools, and associated Items dear of
         main travetways.

FIRE SAFETY

Fire prevention must be given  a  high  priority  during the  design  phase.  The
wood and polyethylene materials used on asbestos removal sites increase the potential for
fires and risk to human Bfe. The project designer will need to be concerned with fire safety
features such as alarm systems, travel distances, exits, and emergency lighting.

A predesign survey of the project site should first be conducted to determine potential fire
hazards, sources of ignition, hot spots, location of fire suppression systems, and  locations
of current exits. The survey data is then correlated to the number of workers that will be in
the area, the square footage of the containment area, and the  types of combustible or
flammable materials that will remain in the  project area.  This information  will allow the
project designer to include fire safety procedures that  will reduce or eliminate the chance
of fire in the containment area.

Untreated polyethylene has a combustion temperature of approximately 150 degrees to
170 degrees.  Polyethylene will start to bum slowly and pick up speed as  more heat is

generated. It gives off heavy black smoke as a combustion by-product  The flame spread
is slow and steady as the combustion process continues.  As an additional concern,
thermal decomposition may produce toxic gases.  The respirators worn by asbestos
removal workers generally will not adequately protect them from the smoke and toxic
gases produced. Because of this combustion threat, designs should require polyethylene
sheeting to be kept away from heat sources such as transformers, steam  pipes, boilers,
and equipment that will be heated during the removal phase.  In  some situations It
may be   necessary  or required  to  specify  the  use  of  flre-retardant
polyethylene.

The project designer should  consult OSHA,  the  National Rre Protection Association
(NFPA), and local fire  code requirements before sealing off an  area  and blocking
entrances  and exits.  For example, a poorly-written contract specification might require
"one means of egress through a property designed decontamination system';  however, a
better and more correct design would require alternative emergency exits and all on-site
personnel entering the work area to be famiiar with these exits.

Some additionaJ fire safety procedures that may need to be incorporated into the project
design are outlined below:

      • Specifications must require all sources of ignition to be removed. Gas and other
        fuel sources must be cut off and pilot lights in boilers, heaters, hot water tanks.
        and compressors extinguished.

       •  Specifications should identify 'hot spots.' Quite often design specifications may
         require draping equipment instead of sealing it off to prevent overheating (i.e.,
         computers, terminal boards, switch panels, transformers).

       •  Require the cutoff of supply to steam lines, electric  and steam heaters, and
         radiators.  Do not permit the polyethylene to lie against hot surfaces.

       •  Specifications must require the marking of exits from work area and posting
         directional arrows when exits are not visible from remote work areas.  This can
         easily be done using duct tape or indelible marker on polyethylene walls and
         barriers.  It is recommended that half of these directional arrows be placed close
         to the ground to assist workers who may  be crawling in smoky conditions to
         escape a fire.

       •  Specifications should require that trash and debris be kept to a minimum (e.g..
         tape, polyethylene, bags, lumber).

       •  If the work area te large and many workers are present, several emergency exits
         may need to be included in the project design.  Choose exits that are  locked from
         the outside but  can be opened from the inside.  A daily inspection must be
         conducted to ensure secondary exits are not blocked.  Many local codes address
         these issues.

       •  Lighting of exits and exit routes should be included in the project design.

       •  The project designer must be alert to the potential flammable vapors in industrial
          areas (solvents such as naphtha, toluene, xylene, etc. during the design phase).
          This is especially critical in industrial vacuuming operations where vacuum
          motors are not explosion proof.  Compressed air vacuums may be required.

       •  Specifications should require a nearby telephone be available at all times for
          notification of authorities in an emergency.

       •  A retractable blade knife should be readily available at each emergency exit for
          use in cutting polyethylene sheeting.

 EMERGENCY PROCEDURES

 OSHA 29 CFR 1926.24 requires that every job site have a fire protection and prevention
 plan. This plan must cover procedures to be used in case of fire, which includes heavy
 smoke conditions, power failure, air supplied respirator compressor failure, accidents, and
 worker injury.

 The contractor wiH need to establish a system for alerting workers of an emergency that will
 require evacuation of the asbestos containment and work area.  A compressed air horn
 provides an effective alarm that can be heard and does not rety on a power source.  All
 persons  entering the containment and work area must be  familiar with the  evacuation
 alarm signal and all primary and secondary exits. A simple floor plan of the work area
 must be posted near the work area entrance to familiarize persons entering the site with
the location of exits, fire suppression equipment, and emergency telephone numbers (see
 Figure VM-3).

HEAT-RELATED DISORDERS

As explained in Section VII covering personal protection, the OSHA asbestos standard  for
the construction industry  requires that al workers who are exposed to asbestos at or above
the action level,  or who  are required  to wear a negative pressure respirator, be given a
complete physical examination.  The main objective of the examination is to determine
whether the employee  is medically qualified to wear a respirator while  performing
abatement activities.  The examining  physician or clinic must additionally be aware that
respirators may be worn under hot. adverse conditions. During warm months, or in hot

       •  Have worker lay down and raise feet
       •  Apply cool wet cloths
       •  Loosen or remove clothing (remove disposal suit)
       •  Allow small sips of water or salt replenishment beverage if victim is not vomiting

Treatment:
      •  Medical emergency
      •  Remove worker from hot area
      •  Remove clothing
      •  Have worker lay down
      •  Cool the body (shower, cool wet cloths)

NOTE:  The major  difference In symptoms between heat exhaustion and heat
stroke  Is  that  with  heat  exhaustion the person  Is pale  and sweating
profusely; and with heat stroke, the person  Is very hot, red, and has dry skin
due to lack of sweating.

The prevention and causes of both heat-related disorders are as follows:

Prevention:
      •  Frequent breaks away from the neat
      •  Increase fluid intake
      •  Allow worker to become acclimatized to heat
      •  External cooling (vortex cooling, ice vests)
      •  Reduce caffeine intake
      •  No alcohol
      •  Breathable protective dothing
      •  Increased air movement

 Causes:
       •  High temperature
       •  High humidity
       •  Low air movement
       •  Hard work
       •  Not enough breaks away from the heat
       •  Insufficient fluid intake
       •  Full-body clothing
       •  Worker not acclimated to heat

 Other measures that can be implemented to reduce heat-related disorders include the use
 of air-supplied cooling vests  (available with high-pressure supplied air systems), an
 increase in number of  HEPA filtration units to Increase air flow, and scheduling work at
 night when temperatures are cooler.

 CARBON MONOXIDE HAZARDS

 When supplied-air respirators are in  use, it is important that an  outside monitor who is
 familiar with the  airline  system  remains close by to correct problems associated with the
 breathing srir.  Carbon monoxide poisoning is perhaps  the  most important of these
 problems.  Carbon  monoxide exposure problems could develop  if  an outside source of
 carbon monoxide such  as a truck exhaust is drawn into the air intake of the compressor
supplying breathing air,  or if  it contaminates  the makeup air being drawn into  the
containment area.   Both of these problems should be taken care  of during the design
phase by requiring  the compressor intake to be elevated 10-15 feet and/or prohibiting
vehicles from idling near the decontamination unit

PERSONAL PROTECTIVE EQUIPMENT

While the enforcement of proper use and wearing of personal protective equipment (PPE)
is the direct responsibility of the employer, the project designer may need to recommend
certain types of PPE on particular projects.  When the project designer recommends or
requires that PPE be used, it should also be required to be maintained in sanitary and
reliable condition necessary to protect workers from hazards which could cause injury or
illness.

When addressing personal protective equipment for asbestos removal personnel,  the
following guidance should be used.

      •  Recommend work gloves as part of PPE to workers exposed to asbestos. This is
         particularly important when  metal lath, suspended ceiling grids, and other
         materials are being removed. The OSHA asbestos standard requires full body
         covering.

      •  Scrapers, retractable knives, wire cutters, chisels and other sorts of bladed tools
         are frequently used and can cause injuries.  Recommend tools with insulated
         handles.
      • Many puncture and cut wounds occur when removing metal lath or cutting duct
        work. Recommend the use of good work practices and PPE and have a first aid
        kit available.

       •  OSHA requires that protective hard hats be worn on a job site where there is
         exposure to falling objects, electric shock or burn.
       •  Recommend the wearing of nonfogging face shields or goggles for operations
         involving potential eye injury.  Full-face respirators are most effective  (if
         nonfogging).

       •  Where possible, design work so workers do not have  to reach extensively
         overhead.  Get them up to the job.

       •  Recommend that workers use proper lifting methods.

       •  Recommend the use of the "buddy system" for lifting and moving heavy objects.

       •  Recommend the use of hand  carts or  rolling pallets when  possible.  Keep
         manual material handling to a minimum.

       •  Recommend proper footwear for the hazards that are  present on the job site,
         Including steel toed shoes, if necessary.

HAZARD COMMUNICATION STANDARD

The hazard communication standard, also known as the right-to-know rule, covers both
general industry and the construction industry.  It was promulgated by OSHA in August
1987 as 29 CFR 1926.59 and 29 CFR 1910.1200.  The purpose of this standard is  to
ensure that the hazards of chemicals or materials used in the workplace are identified and

 that this information,  along with Information on protective measures and procedures, is
 passed on from manufacturer to employer to employee.  Elements required under this
 standard  include a comprehensive written hazard communication  program,  labeling of
 hazardous materials, employee training,  and maintaining material safety data sheets
 (MSDS).

 Employers are required to inform affected workers about hazardous chemicals or materials
 to which they are exposed on  the job site. This notification is done through a written
 program,  maintaining material  safety data sheets,  maintaining labels, and conducting
 worker training on these items.

 The project designer must be aware that exposure to hazardous materials can occur in a
 number of tasks associated with asbestos removal work.   Examples include spray
 adhesives, surfactants, encapsulants, paints, products used for lockdown of fibers, mastic
 removers,  materials left in the work area by the building owner  and, of course, the
 asbestos.  The project designer should require the contractor  to document that there is a
 program in place, that workers  have received  training  on possible  hazards and
 precautions, and that the correct MSDS have been obtained for hazardous chemicals
 being used on site.

All  hazardous chemicals used  on the job  site  must have material safety data sheets
available which  indude all health  hazard  exposures as well as  physical hazards and
emergency procedures (see Figure VI 11-4). The material safety data sheets must be
accessible to all workers during any working time which includes all three shirts  as
applicable.  Material safety data sheets are available from manufacturers, suppliers of
products and from owners of buildings where  hazardous materials are handled in the

INTRODUCTION

Design specifications should contain specific air monitoring requirements for the asbestos
removal project.  The sampling and analytical  methods that will  be used during
various project phases, and the  acceptable  fiber levels associated with each
activity must be clearly stated  In  the  specifications.  This  section covers the
application of air  monitoring for abatement projects, regulatory requirements and
procedures for good practice, how air samples  are  collected, the various analytical
techniques, and interpretation of laboratory data.  Qualifications for the air monitor and the
analytical laboratory are also discussed.

PURPOSES OF AIR MONITORING AND REGULATORY REQUIREMENTS

Air sampling involves drawing a known volume of air through a filter and analyzing that
filter for the presence of asbestos fibers. The filter is housed In a plastic cassette which is
attached to a sampling pump with flexible tubing.  The sampling pump can  be  either
electric (plug in)  or battery powered and is calibrated to draw a known volume  of air
through the filter material over a given period of time, usually expressed In liters of air per
minute (Ipm).

Two basic air sampling methodologies are area and personal monitoring. Area samples
are collected with a pump, tubing and filter cassette (called  the sampling train) at a
stationary location four to six feet above floor level.  Personal samples are  collected in the
same manner as  area samples, except the pump is hung from a belt  around the worker's

 waist and the filter cassette is attached, pointing downward, to the worker's lapel or collar.
 The samples are collected from within the breathing zone (as close to the nose and mouth
 as possible) of an individual, but outside the respirator.

 In relation to asbestos hazard identification and control during removal projects,  air
 monitoring can be used for:

       1.    occupational exposure  measurement
       2.    abatement  surveillance
       3.    abatement clearance testing

 Before  the  removal  project begins, air sampling  may  be conducted  to  determine
 background concentrations.  This is particularly important if there are locations outside the
 contained work area, but within the building, where there are suspected or  known
 asbestos-containing materials or other fibrous  materials which may be interpreted  as
 asbestos.

 During the project, air monitoring is used as a quality assurance tool to determine if
 engineering controls are effective to assess worker exposures and to document whether
 fibers are being contained in the work area. At the completion of the removal project  air
monitoring is used in conjunction with a  thorough visual inspection to  determine if the
standards for reoccupancy have been met.

Occupational Exposure Measurement

The  Occupational Safety and  Health Administration  (OSHA)  requires  the
asbestos  abatement contractor  to conduct personal  air  monitoring  for
workers Inside the abatement area.  Since this is the responsibility of the employer.
specific requirements for personal  air monitoring are usually not included in the contract
documents between the abatement contractor and the building owner.  The contractor may
have a trained employee  who collects the personal samples and submits  them to  a
laboratory, or an air monitoring firm may be retained to conduct personal monitoring.

Exposure levels are measured by sampling the air in the breathing zone of workers who
are conducting  various types of activities such as scraping, bagging  and spraying. For
OSHA   compliance  the  samples  are  analyzed   by  a  phase   contrast
microscope.  Phase contrast microscopy (PCM) will be discussed in more detail  later in
this section.  The analytical results are compared to the following OSHA limits.  (It should
be  noted that these limits are subject to changes In the regulation.   Currently
there Is a proposed  regulation which would lower the PEL to 0.1  flbers/cc for
certain  activities).
               QSHAUmtt               Fiber Concentration       Exposure Duration
       Permissible Exposure Limit (PEL)  0.2 fibers/cubic centimeter (cc)        8 hours
       Action Level (AL)               0.1 fibers/cubic centimeter (cc)        8 hours
       Excursion Limit (Eg             1.0 fibers/cubic centimeter (cc)       30 minutes

Each limit has  associated  worker  protection requirements that must  be invoked  if it is
exceeded. The key limit for asbestos abatement work from a regulatory standpoint is the
permissible exposure  limit (PEL).   Workers must be provided respirators with a high

 enough protection factor to keep their exposures below 0.2 fibers/cc inside the respirator.
 However,  It Is  recognized as  good practice  and  has  been taught In EPA
 curricula  for a number  of years  that 0.01 flbers/cc, not 0.2 flbers/cc, should
 be the limit for  the  level Inside the  worker's respirator (see  the  discussion  In
 Section VW-Protectlon  of Asbestos  Abatement  Personnel).  The requirements
 triggered by the action level and the  excursion limit include continued air monitoring, a
 medical surveillance program, worker training, and documentation.  Since all  of these are
 performed in association  with an  abatement project anyway, these limits  are more
 pertinent to the maintenance personnel and various tradesmen who are also covered by
 the OSHA Standard for the Construction Industry (29 CFR 1926.58} or the EPA Worker
 Protection Rule (40 CFR Part 763 Subpart G).

 The employer must conduct initial, representative monitoring  at the startup of each
 abatement project. This has generally been interpreted as sampling at least 25 percent of
 the workers that are conducting various removal tasks - i.e., scraping, wetting, bagging.
 Personal monitoring must be conducted on a daily basis unless the workers are wearing
 supplied air respirators; or unless the contractor submits data (for OSHA approval) from a
 previous job which is nearly identical to the current project, and the  data indicates fiber
 concentrations did not exceed the action level.  If the daily air monitoring results indicate by
 statistically reliable measurements that exposures  are below the action  level, then the
 contractor can stop daily monitoring.  Monitoring must resume if a different type of ACM is
 encountered or if work  conditions change  in any way.  The  employer  must notify affected
 employees of the monitoring results as soon as they are received from the laboratory.

While the collection and interpretation of personal air sample results is not the regulatory
or legal responsibility of the building owner or the owner's representative, some designers

may elect to require the contractor to submit personal sampling results to the project
monitor.  The monitor can then compare the airborne fiber levels to the protection afforded
by the respirators being used to determine if the contractor is  in compliance with the
regulations  or the project specifications.  Additionally, personal monitoring can be
performed by the owner's representative to evaluate fiber control effectiveness, and results
can be shared with the contractor.

Abatement Surveillance

To  check for potential fiber  leaks during the  removal  phase, stationary area
air  samples are  usually collected from strategic locations around the outside
perimeter of the containment area.  Potential leakage points where sampling should
be conducted include the clean side of the containment barriers separating the work area
from occupied parts of the building, and just outside the dean room of the decontamination
unit.  If the removal project is being conducted In  a multistory building, area samples
should generally be colected from  floors above and below the abatement activity.  The
results of these area samples  are compared to the  background and previous shift
concentrations that were measured In the same locations before the project began.
Usually this concentration is below 0.01 f/cc by PCM.  PCM is used for abatement
surveillance because sample results can  be obtained quickly  and sudden  increases in
fiber concentration  would indicate a  potential problem.

There  is currently  no  regulatory requirement for conducting abatement  surveillance
monitoring outside the  containment area.  It is considered good  practice and is usually
specified to be conducted by an air monitoring firm representing the building owner. The
contractor may elect to conduct abatement surveillance monitoring if the specifications do

 not designate this activity.  The specifications should Indicate what action will be
 taken  If  concentrations that  exceed  background  levels or  some other
 decision criterion,  such as  0.01 f/cc,  are  detected outside the containment
 barrier. In order to use outside air monitoring data as an effective surveillance tool, the
 data  must be available within a few  hours after sample  collection.   Ideally, a  field
 microscope is set up on site and the building owner's representative collects and analyzes
 the samples. A percentage of the filters that are read in the field (typically 10 percent) are
 then sent to a laboratory that participates in a nationally recognized QA/QC program for a
 quality control check.  Refer to the discussion of laboratory and microscopist qualifications
 at the end of this section.

 Area air samples can also be placed  In  locations  outside the building during
 the abatement  project to  detect leakage  of fibers from  the  work site.  Typically.
 pumps are placed at doors or windows near the exhaust of the negative air filtration units,
 and at the waste loadout area. Care must be exercised to ensure that outside samples are
 not overloaded with dust or other debris.  Also, filter cassettes placed too  close to the
 exhaust stream of the negative  air filtration units will not  give a meaningful  indication of
 fiber leakage from these units.  Samples should either be collected  isokinettcaly, which
 demands special sampling equipment and a greater degree of expertise, or placed about
 6-10 exhaust duct diameters downstream from the exhaust unit where fibers are more
 likely to be captured by the sampling apparatus.

 In  addition to outside  perimeter  samples, specifications may  stipulate  the
collection of  area samples  Inside the  containment  area during abatement
This is typically done when there are building occupants elsewhere in the buOding. Two to
three samples with a minimum 600 liters of air each day are usually adequate to index

airborne fiber  concentrations  inside  the  work area.   A  radical increase in area
concentrations would signal that work practices need to be adjusted from one day to the
next.  The design specifications may contain a "stop work" clause If a certain
fiber  concentration Is exceeded In the  work area.  For example, 0.5 f/cc by PCM
may be defined by the designer as the level which cannot be exceeded inside the work
area for a particular type of project  If area air sampling indicates  fibers are being
generated at concentrations above this level then the contractor may be required to stop
work and review wetting procedures,  number of air changes per hour, and housekeeping
procedures in an effort to lower fiber counts.  This serves as an additional safeguard for
preventing contamination outside the  containment barrier. H Is Important to note that
the "stop  work" decision criteria  will vary greatly depending on the type  and
percent of asbestos present, the friability  of the  material,  the ability of the
material to absorb  water and nature of the project

Abatement Clearance Testing

The regulations promulgated by EPA for schools in accordance with the Asbestos Hazard
Emergency Response Act of 1986 (40 CFR 763. Subpart E) outline specific requirements
for clearance testing  of abatement projects.  Currently, there are  no federal  regulations
which  require clearance testing  in  public and commercial buildings.  Many  project
designers elect to apply the protocol  outlined by regulations for clearance in schools to
public and commercial building because it is considered as the current industry standard
and there is published guidance for using the procedures.

 Visual Clearance Inspection
 The   project  specifications  should  clearly  require   a  thorough  visual
 Inspection of  the work area  by the  building owner's representative  prior  to
 final  clearance  air sampling.   Generally,  the owner's representative  and the
 contractor's representative conduct a walk-through to closely check for evidence of visible
 debris on surfaces, in comers and dfficult-to-access places.

 There is a procedure for performing a visual inspection published  by the American Society
 for Testing and Materials (ASTM) entitled Standard E 1368. Standard Practice for Visual
 Inspection  of  Asbestos Abatement  Projects.  The specifications should Indicate this
 procedure will be used, outline an alternate procedure or have the inspector submit the
 visual inspection procedures that will be used in writing to the contractor prior to project
 setup.

 After  each area has passed visual inspection it is common practice for the contractor to
 apply a sealant to the newly exposed surfaces and the inside of the containment barrier to
 lockdown any invisible fibers.  Reference the section on  lockdown  and replacement
 materials.

 AHERA Protocol tor Clearance Testing - Once the work area has passed visual inspection
 criteria, then clearance air sampling  can be performed to estimate the concentration  of
residual fibers.  The AHERA procedures for final clearance air sampling, analytical
sequence and  clearance level requirements for asbestos abatement projects conducted in
school buildings are outlined in  Tables X-1 and X-2.

The  AHERA  protocol  requires  that   analyses  be   performed  with  a
transmission  electron microscope unless  the project Involves less than 160
square feet or 260 linear feet of asbestos-containing  material.  Phase contrast
microscopy can be used to analyze clearance samples from the smaller projects.

For TEM analysis a minimum of thirteen samples are collected with at least five from the
abatement area, five from where the make-up air comes from, two field blanks, and one
sealed blank. Samples are  collected by aggressive air sampling techniques which involve
physically or mechanically agitating the air in the work area during the sampling process.
There is a nonmandatory aggressive  sampling  protocol provided in Appendix  A of the
AHERA regulations.  This procedure provides for using the exhaust of a one-horsepower
leaf blower to sweep floors,  ceilings,  walls and other surfaces in the work area to dislodge
any residual fibers.

Stationary fans are placed in locations which will  not interfere with air monitoring
equipment  Pan air is directed toward the ceilings to keep any dislodged fibers airborne
and at least one fan is used for each 10.000 cubic feet of work site.
The purpose of final clearance  air sampling  using aggressive techniques Is
to produce a "worst case" scenario.  The procedure is designed to sample asbestos
in the  air and on surfaces through reentrainment.  If the  work area passes the final
clearance level in this "worst case" environment, then the likelihood of airborne asbestos
fiber levels above the clearance level when the area is reoccupied is remote.

The AHERA protocol for the large removal projects is designed so that samples can be
analyzed in stages in order to possibly avoid the expense of analyzing all thirteen. The
sequencing of analyses is outlined in Table X-2.  In order to utilize the phased analyses, at
least 1,199 liters of air must be sampled with 25 mm cassettes, or 2,799 liters of air must be
sampled when 37 mm cassette are used.  Initially, the five samples (minimum) collected
from inside the removal area are analyzed by TEM.  If the arithmetic mean of the five
samples  Is less  than 70  asbestos  structures  per square  millimeter  (70
s/mm2) of  filter area, the area passes and can be opened for reoccupancy  by
unprotected personnel.  The 70 s/mm2  criterion is  considered to be the filter
background  leveMhe  concentration  of structures per square millimeter of  filter than is
considered statistically indistinguishable from the concentration measured on the blanks
(filters through which no air has been drawn).

If the arithmetic mean of the five inside samples exceeds 70 s/mm2, then the next step is to
analyze the two field  blanks  and the sealed blank to determine if the blanks  are
contaminated, or if  there  is  some contamination being  introduced in  the sample

 preparation.  If the blanks are contaminated, then the source of contamination must be
 eliminated and resampling must be conducted.

 tf the blanks are not contaminated, then the next step is to analyze the five samples
 collected outside the work area and perform a statistical procedure termed the Z-test on the
 logarithms of the inside and outside sample concentrations to determine  if there is a
 significant difference between the inside and outside concentrations. If the Z-test indicates
 there is no significant difference, then the area passes the clearance criteria and can be
 reoccupied.   If the Z-test indicates  the ambient area samples  are significantly  less
 contaminated with asbestos fibers than the samples from inside the removal area, then the
 contractor must redeem the work area and resampling must be conducted. Additional
 information  regarding the Z-test is provided in the EPA publication 'Guidelines for
 Conducting the AHERA TEM Clearance  Test to Determine Completion of an Asbestos
 Abatement Project" (EPA 56CV 5-89-001).

 The purpose of the Z-test is to make an allowance for projects that are conducted in areas
 that may have elevated concentrations of asbestos in the ambient or make-up air that is
 being pulled inside the removal area.  An example of this might be the illegal demolition of
 a nearby building which contains ACM, or the concurrent performance of an activity with
 PCM clearance controls (e.g.. operations and maintenance work).

 Experience in using this protocol since 1987 indicates that most of the time if the inside
samples fail the initial screening test of 70 s/mm2. then the Z-test is usually failed also.  For
this reason, many  contractors and  designers prefer to reclean the  work area  tf
the first round of  testing  Indicates levels are above 70 s/mm2.  It is common for

the project designer to specify that the contractor will bear the cost for additional testing. If
final clearance is not achieved during the first round of testing.

As mentioned previously, the AH ERA protocol allows PCM to be used for clearance testing
of small removal projects (less than 260 linear feet or 160 square feet). The procedure for
small projects involves collecting only five samples from the  inside of the removal  area.
Samples are collected using aggressive  sampling techniques and approximately 3.000
liters of air should be collected for each sample.  If any one of  these five samples exceeds
0.01 fibers per cubic centimeter by PCM (NKDSH Method 7400), then the work area must
be recleaned and resampled.  This  concentration is  generally considered the limit of
detection of PCM area samples  in an abatement project and is, therefore, issued as a
clearance level.

Other Sampling and Analytical Protocol - While the AH ERA  protocol must be used for
abatement projects in schools, and it is generally recommended for use in commercial and
public buildings, there are some  situations in which  the designer may need to consider
other options. Some examples are provided here to illustrate the point The designer may
want to further consult with an industrial hygienist when developing specifications for these
types of projects.

Two examples of removal projects that may have different clearance criteria are a building
that is going to be demolished (never reoccupied) after the ACM has been removed and a
buikSng in an industrial complex that is older and large amounts of ACM have been  used
throughout the complex.

 For nonschool buildings that are not going to be  reoccupied, a clearance criteria of
 0.01 f/cc  by PCM is commonly used.  The logic for using PCM instead of the more
 stringent TEM analysis is that the building will not be reoccupied and the 0.01 f/cc by PCM
 is not likely to significantly contribute to ambient air contamination when the building ts
 demoBshed.

 In an older industrial setting that contains large quantities of damaged ACM, it may not be
 feasble to achieve 70 s/mm2 by TEM if only portions of the ACM are going to be removed
 at one time.  The  designer may need to collect data on background levels in areas
 adjacent to the planned project to assist in selecting the clearance criteria.

 AIR SAMPLING EQUIPMENT

 A brief overview is presented here to familiarize the project designer with the types of air
 sampling equipment used on abatement projects.

 Sampling Pumps

 Pumps used for collecting asbestos fibers are typically categorized as either high-volume
 pumps which are generally electric (plug in), or low-volume (personal) pumps which are
battery powered.  High-volume pumps are usually calibrated to draw up to ten liters of air
per minute through the filter and are used for area air samping. Since  being able to detect
low concentrations of airborne asbestos fibers relies, in part, on sampling large volumes of
air, high-volume pumps are  useful for sampling In environments where low levels of
airborne asbestos are expected (e.g., following the cleanup of an abatement project).

                                  Section IX - Air S«npEng Protocol. Reqdnnmntt and Dan I
Battery-powered or personal sampling pumps are small, light-weight pumps encased in a
hard plastic sheD.  These pumps are usualy calibrated to draw 1 .0 to 2.5 liters per minute
through the filter when used to index worker exposure  (or potential exposure, when
wearing a respirator) to airborne asbestos fibers.  The pumps are worn on the worker's belt
and the cassette filter, which is connected to the pump with flexible tubing, is placed in the
breathing zone of the worker.
Fitters
Mixed cellulose ester (MCE) is the primary type of filter material that is used to sample
airborne asbestos fibers.  MCE filters consist of cellulose strands bound together in a web
called tortuous pore" and display a  very  irregular surface when observed under
magnification. The MCE fitter media is available in various pore sizes and diameters. For
personal sampfing a 25 mm diameter filter with a 0.8 jim to 1 .2 um pore size may be used.
For clearance testing in accordance with the AHERA protocol, a 25 mm or 37 mm diameter
filter may be used but the pore size must be 0.45 um for an MCE filter.
All filters are housed in a sampling cassette which includes a cap with a plug extension
cowl or retainer ring, the fiter, the MCE diffuser. a support pad, and a cassette base.
Figure X-1 details a typical sampfing cassette figuration. The entire cap is removed when
sampling for asbestos fibers.

Pump Calibration

The calculation of air sampling results are dependent, in part, on the total volume of air
sampled.  The volume of air sampled is the flow rate of the sampling pump (liters of air per

minute, or Ipm) multiplied by the time (in minutes) the pump ran. Accurate calibration of the
pump flow rate, then, is very Important in the calculation of sample results.  The EPA and
OSHA require that sampfing pumps be caltorated before and after each use, and it is good
practice to maintain these calibration records together with other sampling data.

Although not always practical, a primary calibration standard is the best way to determine
the flow rate of a sampling pump.  A primary calibration standard is one that is known to
have the highest degree  of accuracy and repeatability when  determining a pump's flow
rate. Typically, a one liter flow bubble buret or automated soap bubble meter is used as a
primary calibration standard for air sampling  pumps.   From this, a rotameter can be
calibrated and taken into the field to caltxate each sampflng pump before and after use.

It  I* Important to  ensure  that  persons performing air monitoring  are routinely
calibrating  their sampling  pumps.  Regular requests for calibration data, or requiring
this data to  be  included in reports of  sample results, are two ways to help maintain the
technical and legal validity of sampling data. The designer may want to specify that pump
calibration records be submitted as part of the project documentation.

ANALYTICAL ALTERNATIVES

The primary analytical techniques  used  for analyzing airborne fibers collected on a filter
are:   phase contrast microscopy (PCM), scanning electron microscopy  (SEM), and
transmission electron microscopy (TEM). The  fibrous aerosol monitor (FAM)  is an
instrument which can be used in the field to obtain an index  of airborne fiber levels.

 Appications of each of these methods (PCM, SEM, TEM and FAM) in the  analysis of air
 samples for asbestos are discussed below.

 Phase ftantrast Microscopy

 Phase contrast microscopy (PCM) is a technique using a light microscope equipped to
 provide enhanced contrast between the fibers collected and the background filter material.
 Samples for analysis by PCM are collected on either a 25 mm or 37 mm mixed cellulose
 ester (MCE) filter with a 0.8 to 12 micrometer pore size. Filters are then prepared by either
 a liquid chemical solution or an  acetone vapor that renders  the filter material optically
 transparent. The filter Is then examined  under a positive phase contrast microscope at a
 magnification of approximately 400 times. Fibers are sized and counted using a calibrated
 reticle fitting into the microscope eyepiece. PCM  is inexpensive ($15 to $25 per sample)
 and can be performed on the job site in a few hours.

 Phase contrast microscopy is frequently  referred  to as the light microscopy method,  the
 filter membrane method, or the NIOSH method.  PCM is the analytical method specified in
 the Occupational Safety and Health Administration  (OSHA) asbestos standards.  PCM was
 first used to monitor asbestos workers' exposure in asbestos product manufacturing or
 mining operations.   Using  this method the  analyst  does  not Identify what
 materials the fibers  are composed  of,  and only  counts those fibers longer
 than  five micrometers  and wider than  about  0.25 micrometers.  Because of
 these Pmitations. analysis by PCM typically provides only an index of total concentration of
airborne fibers  in  the environment monitored.  As the proportion of the airborne fibers
which are less than 0.25 micrometers in  diameter increases (e.g., nonindustriai settings
such as asbestos abatement projects), PCM becomes a less reliable  analytical tool.

There are three primary fiber counting methods for phase contrast microscopy.  NIOSH
P&CAM 239 is the original method which was implemented for estimating airborne fiber
concentrations.  The NIOSH 7400 method is an improved version  of P&CAM 239 which
provides for a  more  reliable limit of detection.   P&CAM 239 is no longer used  for
compliance monitoring.  The OSHA reference method (ORM) is specified in OSHA
Asbestos Standards and contains modifications to the procedures outlined in the NIOSH
7400 method for use in determining personal exposures.

Transmission Electron Microscopy

Transmission electron microscopy  (TEM) is a technique which focuses an electron beam
onto a thin sample mounted in the microscope column (under a vacuum).  As the beam
transmits through the sample, an  image resulting from varying density of the sample is
projected onto a fluorescent screen.  Air samples for TEM analysis can be collected on
either mixed cellulose ester or polycarbonate filters.  Filters may be prepared using the
direct transfer technique which allows for the transfer of a carbon-coated replica of the filter
material (with embedded fibers and particulates, etc.)  onto a copper grid suitable for TEM
analysis.  Alternatively, the indirect preparation technique may be employed. The uses
and limitations  of each technique are  more fully described in  the EPA  publication,
"Comparison of  Airborne  Asbestos  Levels Determined by  Transmission  Electron
Microscopy (TEM) Using Direct and Indirect Transfer Techniques," EPA publication 560/5-
89-004, Washington, DC, 1990.

Several methods exist for the  preparation and analysis of air  samples by  electron
microscopy.  Most significant are the mandatory and nonmandatory TEM methods set forth
as appendices to 40 CFR 763, Subpart E (AHERA regulations).  These methods are to be

 used, with restrictions, for analysis of final clearance air samples on school abatement
 projects.  Other methods include the NIOSH 7402. and the EPA Level I, II and III (Yamate
 method).  Depending on the method used,  preparation of the sample can take as long as
 24 hours (or more) and analysis can take several hours to a day  or more.  However.
 standard preparation and analysis time for AHERA clearance samples is now in the range
 of 12 hours or less.  As the number of laboratories with TEM capability continues to
 increase,  the cost and turnaround time has gone down.  Costs for TEM analysis typically
 range from about $150 to $400 per sample.

 Scanning Electron Microscopy

 Scanning electron microscopy (SEM) is a technique which uses a  finely focused electron
 beam on  the sample surface to generate an image of the surface shape. A magnified
 image is produced on a viewing screen. Air samples for SEM filter counting are collected
 on a mixed cellulose ester or a polycarbonate filter with a 0.45 micrometer pore size.  The
 cost is about $150 to $300 per sample and may require several days to obtain results.

 SEM  can identify large fibers by morphology (physical appearance) and elemental
 analyses when  equipped with an energy dispersive X-ray analysis system.  Fibers which
 are 0.05 micrometers in diameter are about the  smallest that can be detected  using SEM
 under optimal conditions.  This method has fiber  identification problems with thin fibers and
 flat, piaty particles that display poor contrast. Also, there is  no standard protocol for this
 method.   Currently, SEM provides somewhat better  Information than PCM
analysis, but the  method cannot be used  to  conclusively  Identify or quantify
asbestos. SEM is not routinely used for air monitoring associated with asbestos removal
projects.

The fibrous aerosol monitor (FAM) is an instrument which uses laser light and electrical
field technologies for a  near real-time analysis of the fiber content of the air.  The
instrument provides a continuous  measurement, with direct readout of the number or
concentration of airborne  fibers. It has a flow rate of about 2 liters per minute. The FAM
can be used in conjunction with a strip chart recorder to provide a record of air quality
conditions.  Typically used as an Indicator  of airborne fiber level* rather than a
precision  testing  device,  the RAM's more  useful function Is to alert personnel
to any sudden elevation of the area fiber count.  If the FAM is used on a project it
should be used in conjunction with other traditional air sampling techniques and not in
place of them.

This instrument does not distinguish fiber types and cannot discriminate between fibers
and certain particles that  have  sufficient  shape  irregularities to  possess  fiber
characteristics. The FAM does not detect fibers less than 0.5 micrometers in diameter.
Laboratory tests indicate FAM concentration readings are generally within ± 25 percent of
the optical membrane filter count. Also, in order to obtain accurate low level (0.01
flbers/cc) readings It is necessary to operate the FAM for long periods (1000 minutes);
even though the FAM will register these levels after one minute.

DATA INTERPRETATION
With the use of various analytical methods for asbestos sample analysis which  have
different counting protocol and different analytical  reporting  units, it can be difficult to
understand what the results mean.  No attempt is made here to interpret air monitoring

 data with  respect to health  effects because  many more  years of  medical and
 epkJemiological research wilt probably be required  before this is clearly understood.
 However, a discussion of the reporting units and the definitions of a fiber as used in the
 different counting protocols should help the designer better understand the limitations and
 the usefulness of the data.

 As discussed earlier, the OSHA standard which  covers  worker exposure monitoring
 requires analyses of these personal  samples to be  conducted  by phase contrast
 microscopy.  The counting protocol requires the analyst to only count those fibers that are
 at least three times longer than they are wide, and that are at least five micrometers long
 (approximately 1/5000 of an inch). The OSHA permissible exposure  limit (PEL) of 0.2
 fibers/cc Is somewhat difficult to visualize.  It can also be expressed as 200,000 fibers per
 cubic meter of air.  Another way to understand the 0.2 fioer/cc PEL is to visualize the size of
 a 10* x 10'  room with a 10' ceiling.  If this room had an asbestos fiber concentration of 0.2
 fibers/cc, there could be over 5,000.000 fibers in the room.

 The AHERA protocol defines a fiber differently than the OSHA protocol.  The analyst is
 required, using transmission  electron microscopy, to count asbestos structures that have a
 length to width ratio of at least 5:1 and to count any asbestos structures that are longer than
 0.5 microns.  Structures are classified as fibers, bundles, dusters or matrices as illustrated
 in Figure X~2. Another difference is that the AHERA clearance level of 70 s/mm2 is based
 on the number of fibers per filter area. The OSHA PEL is expressed as an airborne fiber
concentration (fibers/cc).

White an entire course could be devoted to understanding analytical techniques and data
interpretation, this short overview has been presented to help illustrate the complexity of

QUALIFICATIONS OF THE AIR MONITOR AND PROJECT MONITOR

The terms air monitor and project monitor have commonly been used interchangeably. For
the purposes of the discussion on qualifications, the air monitor will be defined as the
individual who collects air samples and reports the analytical results.  The project monitor
has a greater  responsibility  which may  include acting  as  the building owner's
representative  to  perform quality assurance on  the  contractor's work, construction
management and visual clearance prior  to clearance sampling. The project monitor may
also serve as the air monitor or may interact with the air monitor.

There are currently no federal requirements for certification or licensing of individuals or
firms that conduct air monitoring or project monitoring on asbestos abatement projects. A
few states do have requirements for training and experience.  The following are provided
as minimum guidelines for designers who are developing specifications for  projects in
states that do not have provisions for air monitoring or project monitoring personnel.

Air Monitoring Personnel

      •  Should have current training certificate from an EPA Model Accreditation Course
         for Asbestos Abatement Project Supervisors or Designers.

         monitor.
 Project Monitoring Personnel

       •  Should have current training certificate from an EPA Model Accreditation Course
         for Asbestos Abatement Project Supervisors or Designers.

       •  Should have construction management experience and knowledge of reading
         blueprints, specifications and contract documents.

       •  Should have on-the-job training under the supervision of an experienced project
         monitor.

QUALIFICATIONS FOR ANALYTICAL LABORATORY

The  AHERA regulations outline  quality assurance/quality  control  procedures for
laboratories that  perform TEM analysis of clearance samples collected  on school
abatement projects.  It is recommended that design specifications for nonschool buildings
also impose these requirements on the laboratory performing analyses. They include:

       • Participation in the  National  Voluntary Laboratory Accreditation Program
         (NVLAP) administered by the National Institute of Standards and Technology
         (NiST).

       • Perform quality control/quality assurance procedures in accordance with AH ERA
         protocol (Table X-3).

For laboratories performing phase contrast microscopy (PCM), qualifications of each
analyst should include:

       • Satisfactory performance In the Proficiency Analytical Testing (PAT) Program
         sponsored by the National Institute of Occupational Safety and Health (NIOSH)
         and/or satisfactory performance in the Asbestos Analyst  Professional Registry
         Program sponsored by the American Industrial Hygiene Association (AIHA).

       • Successful completion of a 40-hour training course in air sampling and analysis
         (NIOSH 582 or equivalent.)

In addition to these quality assurance/quality control programs, laboratories may also be
accredited by the AIHA  Laboratory Accreditation Program.  This provides  additional
assurance  that the  laboratory  exercises good  general laboratory practices and
recordkeeping procedures.

SUMMARY
Sampling and analytical techniques provide one quantifiable method for determining if the
design specifications are being executed properly.  There are a variety of sampling and
analytical techniques  and the appropriate ones must be selected to collect data that is
representative of the environment being sampled.  Project designers must have a general
understanding of the various sampling and analytical techniques employed. They should
also understand  the  limitations  of the data  that is generated by each procedure to
recognize potential weaknesses and strengths in the design specifications.

            LOCKDOWN  AND REPLACEMENT MATERIALS

 INTRODUCTION

 The use of asbestos in products manufactured in the United States has declined sharply
 since the mid-1970s when federal, state and local agencies began instituting regulations
 to restrict human exposures to airborne asbestos fibers.  This trend  culminated in 1989
 when the  USEPA  issued a ban and phase-out rule which proposed a timetable for
 eliminating the manufacture of  most asbestos-containing products.  The ban was recently
 overturned by  a  federal court (reference the regulations section).   However, the
 replacement of asbestos-containing building products with asbestos-free substitute
 materials remains an important issue for asbestos abatement project designers. They are
 usually responsible for specifying a  replacement material that will adequately serve the
 same function as the ACM that  is being removed.

 This section will review design considerations, materials and methods involved  in the
 replacement of asbestos products which are  removed from buildings.  First a detailed
 review of the lockdown procedure which is used to trap any remaining  nonvistole asbestos
 fibers on a substrate prior to the application of replacement materials will be discussed.
 This will be followed by a discussion of the types and features of commonly used asbestos
 substitutes in building products.

 LOCKDOWN

 Lockdown  Is  the  procedure of applying  a protective coating or  sealant  to a
surface  from  which  all   visible asbestos-containing  material  has  been

removed.  Its primary function is to control and minimize the amount of airborne asbestos
fiber generation that might result from any remaining material that cant be detected during
visual inspection. Lockdown is different from  encapsulation which is the appBcation of a
liquid bridging or penetrating encapsulant to  asbestos-containing material that has not
been removed.

Depending upon the surface  structure and texture  of the substrate,  or the adhesive
strength of the asbestos-containing material to the substrate, there will  always be some
residual fibers left behind after gross removal has taken place. Even when the substrate is
smooth and appears clean there could still  be invisible asbestos fibers present  The
lockdown procedure is the standard means of assuring that any remaining asbestos fibers
are "locked" in place. Because a lockdown involves coating the substrate with a virtually
impermeable barrier, it must also be designed with the subsequent replacement materials
in mind.

Lockdown Design

Prior to  lockdown  design and  before any  asbestos is  removed, it is  essential  to
characterize the substrate. Some of the most common materials found as  substrates in
buildings include cement, corrugated sheet metal, metal beams, wire  mesh,  metal piping,
plaster  'brown  coat," wallboard and wood.  These materials each have different
characteristics pertaining to surface structure and texture which affect the ability of other
materials to bond to  them. For example, cement substrates are often porous  and pitted
(many small grooves or  depressions on the surface).  This  uneven surface is  extremely
difficult to clean for two reasons.  First, the pits in the surface may have become filled with
asbestos-containing material when it was originally sprayed or troweled on  the surface.

-------
STUDENT MANUAL                                        ASBESTOS ABATEMENT PROJECT DESIGN

Secondly,  when the material  is scraped  away during  removal, asbestos-containing
materials will be packed tightly into these grooves or pits.  Most of the material can then be
removed through tedious brushing; however, some fibers will remain.

Some substrates are imposstole to reach without demolishing the structure.  An example of
this is fireproofing which was applied to structural members before installing a curtain wall
exterior.  In this case, it may not be possible to completely remove the fireproofing wedged
between the  beams and the curtain wall before lockdown.  In this  event, the only option
may be to  encapsulate the material that cannot be removed and construct a permanent
physical enclosure to isolate  the material from the accessible ACM during removal and
prior  to lockdown.  When material is  left in place it is a good practice to apply  visible
warning labels in each area.

A  variety of  products can be used for locking  down the substrate.  These lockdown
products are usually applied  as sprayed-on liquid-type sealants (alternatives for certain
situations are latex paint, encapsulating solutions, and concrete sealant).  Caution should
be used so that the lockdown material does  not present an  additional  hazard  during
application and anticipated  use/conditions.   Contractors should obtain all  available
information on the substance (i.e., toxlcity.  volatility, fire ratings).   Material Safety Data
Sheets (MSDS) are a good source of information.  These sheets should be available from
both  the  manufacturer  and distributor of  the material.   Under OSHA  "Hazard
Communication* requirements, contractors are required to train their employees so that
they understand and know how to use the  material safety data sheets.  All information
should be obtained and evaluated prior to beginning the project.

                                                                             Page 4
Many lockdown materials are not fire rated (they may actually be more flammable than me
substrate) and thus could greatly reduce or eliminate the fire rating of some replacement
materials. For instance, the substrates of some buflding systems such as pipes, flues and
boilers have high temperature requirements (over 250 degrees) which could exceed some
lockdown material specifications. A designer should consult with the manufacturer of the
Jockdown material regarding any heat limitations.

Another consideration is the compatibility of the lockdown material with the substrate. It is
important to ensure that  adhesion occurs between the  two surfaces (substrate and
lockdown material)  and.  In  some  cases,  three  surfaces  (substrate, lockdown. and
replacement or reinsulation).  For example, latex paint may work well in locking down a
porous concrete surface, whereas it would not be acceptable for use on metal piping since
It would peel and crack.  It is recommended that a field test application be conducted on a
small portion of the substrate prior to widespread use to determine whether the  lockdown
and replacement products will perform as desired.  It is essential to determine compatibility
between lockdowns and replacement materials. Noncompatible materials may void  UL
ratings and manufacturers' warranties.

Another  good,  recommended practice is to use color tinting when applying  lockdown
materials. This will make  it easier to visually check that all areas of the substrate have
been covered with  the lockdown substance.  One coat of lockdown substance will  usually
be adequate to prevent the  generation  of airborne residual fibers.   In  some  cases.
additional coats may  be needed for cosmetic purposes.  Also, if the lockdown material is
being applied to metal substrate surfaces, it may be most advantageous to apply one fairly
heavy coat of primer to act as both a lockdown material and corrosion inhibitor, regardless
of whether or not reinsulation is taking place.

 Lockdown Methods
The lockdown procedure begins after gross  removal and dean ing of the asbestos-
containing material is complete. The recommended method for brushing or cleaning a
substrate after gross removal has taken place is to use a nylon brush.  This will aid in
getting to fibers that may have become lodged in grooves or crevices in the  substrate
surface.   Wetting  of the substrate should also take place while this brushing is being
performed since the chance of airborne  fiber  generation is still present.  Use of wire
brushes is discouraged since it is suspected that wire tends to break down  larger asbestos
fibers or  fiber bundles into fibrils of minute size which are easily dispersed throughout the
surrounding air.   The  use of wire brushes  can  generate high fiber  counts in  the
containment area.  Heavy fiber dispersion can also make final cleaning very difficult  In
either case, wire or nylon brushing will generate  airborne fibers to some degree.

Once this brushing is completed, a final cleaning  of the substrate and work area should
take place in  order to ensure that all loose residual fibers  are  eliminated. It may be
necessary to wipe  some surfaces with a lint-free rag and dusting agent once it has dried.
The use  of cleaning fluids or solvents which leave a residual 'film* on the substrate is
discouraged.  Some chemicals interfere with the adhesive properties  of lockdown
materials. When in doubt, check with the manufacturer of the products.

After the  substrate has completely dried,  a  thorough inspection must be conducted for
visible residual contamination,  It is Imperative that this  Inspection Is conducted
by  the building owner's representative and that application  of the lockdown
material  Is done  ONLY AFTER  the substrate Is found to be visually clean.

Once the substrate has passed visual inspection a lockdown material can be appBed.  The
use of  double layers of polyethylene on the walls and floors during preparation of the work
area will result in greater efficiency at this stage since the inside layer can be removed
after the initial lockdown application takes place.  This reduces the amount of detailed
cleaning.

Workers performing the lockdown operation should wear disposable protective dothing
and respirators suitable for asbestos and organic vapors (if applicable) because the area
is  still  considered contaminated.  Respirators  which provide protection  against both
asbestos fibers and organic vapors may be needed if the lockdown material contains
volatile  organics in  liquid form when being applied; however,  many lockdown materials
currently available are water based and are considered to present very little, if any,
respiratory hazard.

When planning a lockdown operation, It is Important to follow a logical sequence of events.
One sequence that has been proven to work in the field is outlined below:

       1 .     Complete removal of asbestos-containing material from the substrate.

      2.     Collect as much of  the asbestos-containing waste material as possfcte and
             transport it  out of the work area enclosure according to appropriate asbestos
             waste-handling procedures.

      3.     Clean all visible debris by  HEPA vacuuming and wet wiping.

      4.     Conduct a visual inspection of the work area enclosure for any remaining
             visible debris and reclean  If necessary.
      5.     Only  after  the work area  has passed  Inspection  for  asbestos-
             containing  debris and the asbestos waste containers  are  completely
             removed from the enclosure,  one fairly heavy coat of lockdown sealant
             should be spray applied to the substrate.  At the same time, the  inside layer
             of  polyethylene  should  be misted with a  coat of lockdown  material.
             Lockdown materials should be applied using an airless sprayer.

      6.     After the lockdown material has dried (time is dependent on type of material
             and the manufacturer's recommendations), the inside layer of polyethylene
             on  the walls and floor of the enclosure should be  removed,  treated as
             asbestos-containing waste and transported out of the work area.

             dust on surfaces.  If asbestos contamination is detected, additional HEPA

             this time.  If desired, a second lockdown misting can  be performed on the

             proceeding.  At this point, preclearance monitoring may be conducted to
             determine if any airborne fibers are  remaining.  In  the event these air
             sample results indicate the work area is still contaminated, another round of
             cleaning and locKdown should be conducted.  The second layer may be
             taken down and disposed of as asbestos-containing waste if preliminary air
             sample results indicate an acceptable clearance level.

       9.     While special items such as doors, windows, and HVAC systems remain
             sealed (critical barriers), conduct  final clearance air monitoring  using
             aggressive sampling techniques.

Once the lockdown sealant has been applied and after the final clearance  monitoring has
taken pJace, the next step may be to reappty an adequate substitute replacement material.
To avoid conflicts between parties involved in the project, the designer should remember
the  importance of proper  sequencing  and  scheduling  of the  removal/lockdown/
replacement  process.  Either  this  sequence should  be  outlined In the project
specifications or the contractor should  be required to  submit his sequencing
plan for approval by the project designer.  The  designer  may also specify that the
replacement contractor is ultimately responsible for reviewing and accepting the condition
of the substrate prior to application of replacement materials.

REPLACEMENT

Increasing  asbestos regulation  and  health  concerns have created  a new branch  of
materials science to develop and improve asbestos replacement materials.   There are
many products that have  been used or are being experimented with as  substitutes for

 asbestos.  Some substitutes have been used for years and some perform better than
 asbestos counterparts.  Each of these materials has special qualities which make it a
 suitable replacement material for asbestos in certain cases.  The difficulty lies in the fact
 that none of these materials alone can  be as universally applied for as many different
 functions as asbestos was. Many substitutes are more expensive, do not perform as well
 and are not as durable as asbestos products.  There are also concerns about the
 health risks  possibly associated  with some asbestos substitutes.  Therefore, it
 is imperative that the selection of substitute materials be an important consideration during
 the  design of an  asbestos  abatement  project.  The  individual who  is specifying
 replacement material(s), should have the capability to investigate and recommend various
 types of asbestos substitutes.  This person should be very familiar with the chemical and
 physical properties of the various materials available and  which materials are most
 compatible with the building structure; specifically, the acoustics and fire ratings.  The
 designer specifying replacement materials may need to consult a mechanical engineer for
 specifying  replacement of thermal system insulation or an industrial hygienist, for
 information regarding  potential health hazards or safety problems.  The actual design of
 the asbestos replacement operation should be conducted by an individual who has formal
 training or knowledge  In pertinent  aspects of state and  local building  codes and
 knowledge of the particular replacement material application.

 Replacement Materials

The  use of asbestos in building products was primarily due to  its properties of  heat
 resistance, reinforcing strength and chemical resistance. Its performance and low cost led
to widespread use  in buildings in  fireproof ing.  cement  panels, thermal insulation,
acoustical treatment, flooring and adhesives, among others.  Many materials have been

developed as substitutes for asbestos.  These materials can be generally classified into
three categories:
       1.      Man-Made Mineral  Fibers  - including glass  fibers  (fibrous glass or
              fiberglass), mineral wool, glass wool, slag wool and refractory ceramic fibers
              (RCFs);

       2.      Synthetic Materials - including carbon fibers, aramid fibers, polypropylene
              fibers and  metallic fibers;

       3.      Natural Materials - including minerals (perilte, vermiculite,  mica, talc) and
              organics (cellulose fibers, vegetable pulp).

The above substitutes have a wide range  of performance characteristics. For instance,
minerals,  mineral wool and refractory fibers are characterized by good heat resistance
whereas cellulose and many synthetics are not.  The air pockets in celluose do make ft a
good  insulation material.  Aramid fibers,  carbon fibers  and steel fibers are used for
reinforcing strength while minerals must be  reinforced.  The synthetics are  highly chemical
resistant but cellulose is  not.

There is also a wide range of costs for the substitutes. The costs of raw minerals, cellulose,
glass wool and mineral wool are comparable with asbestos. The price of  synthetics such
as aramid fibers and carbon fibers  can be  many times the cost of asbestos.  Beyond the
price  of  raw materials,  the price  for substitute products  relative to asbestos  is also
increased in many cases by costly manufacturing requirements.

Traces of asbestos have been found in some products which are sold as 'asbestos-free*
substitutes.  It is recommended that the project designer should research manufacturer's
standards for determining asbestos content and seek documentation which provides
assurances that a  product does not contain asbestos. Bulk Sampling and analysis (PLM
or TEM) could be used as a final quality assurance measure to detect for the presence or
absence of asbestos in replacement materials.

Despite these roadblocks, many replacement materials  have  been established as
technically and economically viable substitutes for asbestos products. While it is true that
no  one substitute is available as a  universal substitute for asbestos, alternatives  are
available depending on the desired use. A general discussion of the types of substitutes
available for the more common asbestos-containing building products is provided below.

Sorav-Aoolled  Materials - Spray-applied asbestos-containing  materials were used for
fireproofing. thermal and  acoustical insulation,  condensate  control, and  decorative
purposes. Since the focus of many asbestos removal projects has  been on spray-applied
asbestos-containing materials, several substitutes have been developed as replacements.

Replacements  used  for  thermal insulation  often  contain mineral  wool, exfoliated
vermiculite, treated cellulose (with boric acid)  for fire resistance, or glass fibers.  Some
products contain  a combination  of these substitutes.   In  some  instances, it may be
necessary to  replace asbestos-containing fireproofing on steel  support beams with
asbestos-free  fiber-reinforced cement boards.  Cement boards  will often consist of
minerals reinforced by glass or cellulose fibers.

                                                                             Page 12
Numerous options exist for replacement of spray-applied acoustical insulation.  Acoustical
treatments, usually used on ceilings, absorb some sound which limits the amount of sound
reflected from a surface.  Spray-appPed cellulose, mineral wool, fibrous glass and pertite
(a porous volcanic mineral) are often used.   Sound-absorbing fibrous glass boards,
frequently covered with a fabric, may also be used. A suspended acoustical ceiling, or waB
assemblies  utilizing cellulose and/or mineral wool panels, can also be employed.  The
designer should always consider the suitability of the appearance of the  replacement
design.  If a spray-applied  material is used,  a sample should be requested from the
manufacturer to demonstrate the texture and final appearance of the material.

When considering alternatives to spray-applied asbestos-containing materials, be sure to
ask. 'Is the material necessary?'  The building codes determine whether the structure
should be protected with some type  of fireproofing or left unprotected. Square footage,
height of the building, and the type  of building use are evaluated to determine  the fire
rating of materials  specified for construction. In accordance with these codes, the need for
fireproofing  may have been efiminated by changes in the  occupancy use applied to the
building over its life history.  For example, a building used for large assemblies may now
be used only for small assemblies, an educational facility may have been  converted to
business offices, or a factory/industrial site may have been converted to storage.  Also,
there are instances where  building owners  have had their building fireproofed  even
though  the  codes did not require it and replacement of these materials would not be
necessary.   An alternative may be the  installation of a sprinkler system in lieu of
fireproofing. depending upon occupancy use.

 Asbestos-containing decorative sprays, once removed, may be replaced with a coat of
 paint or a decorative (textured) plaster.

 Thermal  System Insulation - Numerous alternatives to asbestos-containing  thermal
 system insulation are  available.   The choice  of substitutes  is usually based on  the
 temperature of the pipe to be covered. Foam rubber, cork or fibrous glass are often used
 on cold water pipes and air conditioning lines.  The  purpose of this covering is often  for
 condensate control rather than insulation.

 Fibrous glass and asphalt-impregnated paper are frequent substitutes for hot water pipe
 insulation where temperatures are not extreme.  Insulation of high-pressure steam lines.
 however,  usually requires the use of refractory fibers, cellular glass or reinforced calcium
 silicate.  The reinforcement  fibers  used may be mineral wool or another nonasbestos
 substitute.

 Asbestos Cement P[pducts - The majority of the asbestos stiB in use in the United States
 goes into manufacturing cement asbestos products, such as pipes and  mill board. Several
 substitutes are available for these asbestos-containing products. Glass-reinforced plastics
 can be used in place of asbestos  mill board but do not possess the fire resistance of
 asbestos mill board and  may give off toxic fumes during combustion.

When glass-reinforced cement was first introduced, there were problems with the Portland
cement degrading the glass fibers.  New high-zirconia. alkali-resistant glass fbers have
greatly reduced this problem.  The price of the asbestos-free cement pipe and mil board is
near the price of traditional asbestos-containing cement products.

Metal and plastic (PVC) pipes have been available for many years.  These are suitable
substitutes for asbestos cement pipe in most instances.  Large diameter pipes require
more support than plastic can otter. For this reason, steel-reinforced cement and welded
steel pipe is often used.

In summary, alternatives are now available for practically all uses where asbestos cement
products were once the only choice.

Roofing - Asbestos-containing roofing felts are frequently replaced by glass fiber mats
impregnated with bitumen.  Research continues in this area  since the  glass  fiber
replacements are inferior to asbestos from  the standpoint of fire resistivity.  Other options
are  organic  bituminous felts which contain cellulose or other organic  fibers and
elastomeric rubberized membrane roofing.  However, these materials do not have the heat
or chemical resistance of asbestos and are not considered durable.

Flooring - Asbestos-containing floor tile has been replaced by vinyl tile which is reinforced
by glass or mineral wool.  Unfortunately, these tiles generally do  not have the strength,
wear resistance or nonslip surface of asbestos tiles.  Some manufacturers offer flooring
products which have eliminated fiber reinforcement through the use of advanced polymers.
The asbestos backing of sheet flooring has been replaced by sheeting reinforced with
glass or mineral fibers.

Adhesives - Notable exceptions to the abundance of replacement building products are
the adhesives,  sealants and mastics commonly used in construction.  Many floor tile
adhesives, roofing repair compounds, window putties and other such products used today
contain  asbestos.  The unique properties of cohesion, adhesion, elasticity and durability

offered by asbestos in these materials have frustrated manufacturers' attempts to find a
viable substitute.  Some asbestos-free products are available; therefore, a project designer
should look carefully at the performance specifications of these products and consult with
manufacturers  regarding the suitability of asbestos-free replacement materials. Bulk
sampling and PLM and/or TEM analysis of replacement mastics, adhesives. and sealants
may be specified by the project designer to confirm these materials are nonasbestos-
con tain ing prior to application.

HEALTH EFFECTS OF SUBSTITUTES

A valid concern held by many persons choosing asbestos substitutes is whether  the
substitute may also pose potential health hazards.  Most of our knowledge on the health
effects of asbestos comes from research that  was conducted only during the  last sixty
years.  While much has been learned, there are still uncertainties regarding exactly how
asbestos fibers cause disease.  Health risk information based on reliable data  for many
asbestos substitutes is inadequate or nonexistent.   Fortunately, much  of  the  recent
lexicological research on asbestos has provided some insight into the potential  health
effects of fibrous substitutes. Based on this research, some general conclusions about  the
risks of fibrous asbestos substitutes can be made:

       •  Fibers of the same size range and shape as commercial asbestos should  be
         considered as potentially harmful;

      •  The most durable fiber types are the most harmful;

-------

                                                 Section X - Locfcdown and Ftop*ac*m*rt Matarufc
       •  The size and durability of the fibers will depend on, among other things, the
         intended use. method of manufacture and chemical composition;

       •  Smoking increases the risk of disease in workers exposed to fibers;

       •  When available  for a specific application, the use of  nonfibrous substitutes
         should be strongly considered.

Asbestos substitutes were developed because they  possessed properties similar to
asbestos. Therefore, it is  not a surprise that some types of the three main categories of
asbestos substitutes are suspected of health risks similar to asbestos.  Man-made mineral
fibers, such as glass wool, that have fibers in the same size range as asbestos fibers
appear to cause some of the same harmful effects. The durability of these fibers varies, but
workers in the rock or slag wool industry have developed lung cancers with similar latency
periods as asbestos (more than 30 years). Synthetic organic fibers are usually bigger than
the asbestos fiber size range, but some of the newer and more durable fibers break into
smaller fibers when  abraded.  There are also concerns about toxic fumes released during
the combustion of synthetics.

The natural organic fibers are not considered a problem in themselves, but they  can
release bacteria and fungal spores during processing which can cause illness and lung
scarring.  This problem is  controlled by wet processing and other dust control methods.
Minerals  such as  talc and  vermiculile have been found to be contaminated by naturally-
occurring amphibote asbestos fibers such as tremolite and actinolite.  In any event, the
substitute chosen should be  Investigated  to minimize the  chance of simply
replacing one potentially harmful material  with another.

SUMMARY
The practice of locking down the substrate is a critical step in the cleaning sequence of
asbestos removal procedures. It can aid in minimizing the regeneration of asbestos fibers
left on the substrate after removal, which will in turn help to make the area acceptable for
reoccupancy more quickly.  Additionally, asbestos abatement designers are often called
on  to specify replacement operations once  asbestos-containing materials are removed
from a facility.  This section provides some basic information about available substitutes
which the project designer will need to augment with research on specific products.   It is
essential that the designer have a thorough understanding of how and why asbestos was
used in certain cases and which products may serve as the best substitutes.

              LEGAL AND INSURANCE  CONSIDERATIONS
 INTRODUCTION

 Since an asbestos abatement project designer typicaDy acts as a representative of the
 building owner, he or she should be familiar with the legal liabilities that may be incurred
 by the building owner as well as those associated with designing the project.  This section
 will review the areas  of potential liability  and insurance considerations for  project
 designers, cover related insurance and bonding issues and discuss some of the important
 legal aspects of contracts for asbestos abatement work.

 LIABILITY OF PROJECT DESIGNERS

 Project designers face liability and litigation issues due to the critical role they play in the
 asbestos management  and control process.  The design documents outline the primary
 methods for performing the work and protecting human health and the environment.  If a
 problem such  as  migration  of fibers outside the work area occurs in connection with
 performance of the work, as a result of poor design specifications, the project designer may
 be liable for any resulting injury or damage.

The  project  designer  should  be  concerned  with three  areas  of potential
 liability:  contractual liability, tort liability and  regulatory  liability.

Contractual Liability
Contracts are complex legal documents and must be carefully reviewed and understood.
Legal advice may be necessary. The project designer may be liable for breach of contract
if the contract requirements are not property performed.  There are several project design
issues relating to potential contractual liability that must be addressed.

Project Scooe - A scope of work which clearly states the services that will be
provided by the project designer to the facility owner Is essential.  Care must
be taken to define the services to be performed and area(s) of the facility that are involved.
It is also important to define the responsibilities of the facility owner.

Work conducted on Fixed-Fee Basis - The fee to be charged for services must be
specified in  the contract.  Design work for asbestos abatement is often conducted on a
fixed-fee basis.  Under this scenario, if unanticipated conditions such as the discovery of
asbestos in  the ceiling tile (previously unreported) increases the amount of design work.
the designer would be liable for conducting that work within the fixed fee.  One method of
avoiding this is to include language in the contract which provides for additional funding if
the work, as a result of unanticipated conditions, turns out to be significantly different than
the original scope of work.

Schedule for Dellverables/Tlme for Performance - The timing  of the completion of
construction  documents can be of great concern to a school district or commercial building
owner and the subject of breach-of-contract action or  liquidated damages.   If school
officials or facility operators have a timetable by which  they must solicit bids  from

contractors or apply for federal or state funding, the completion of the project design and
associated documents becomes an important contractual consideration.
Reliance on Previous Survey Results - The extent of reliance  on previous survey
results Is another area in which the building owner and project designer should have a
clear contractual understanding. Typically, the designer will need to supplement the
survey data with additional samples, confirmation of  material quantities and building
dimensions.  The facility owner/operator may want to save  money  in the short term by
economizing on obtaining additional services; however, such practices could  cause legal
problems for  the  project designer later  if the  original  survey was inadequately or
improperly performed.

Inherent Requirements  Placed on Licensed  Individuals - In those  states or
localities  which  require  asbestos abatement  design to  be conducted by a licensed
architect or engineer, or a professional of a specific designation, the designer should be
aware of a variety of inherent contractual requirements.  For example, regulated architects
and  engineers are  required to  comply wrth building  codes  to retain  this license.  If a
designer  provided  specifications for asbestos abatement  design  and renovation but
neglected to Incorporate code requirements, he or she could be contractually liable to
correct the omission. This could be a significant expense depending  on the size  of the
project.  In addition, the contract will generally require that the designer be properly
licensed.  Failing to  do so may require that design documents be approved by the properly
licensed professional at the expense of the designer.

Requirements for State-oMhe-Art Protocols - Contract language which should  be
approached with caution includes the requirement for "best practices* or "state-of-the-art"

 protocols for project design.  These requirements must be defined. As an example, if a
 designer specified clearance after removal of ACM by phase contrast microscopy instead
 of transmission  electron microscopy because the building owner did not want to pay the
 added cost, this must be documented in the contract; otherwise, the designer could be
 involved in a dispute over asbestos-related property damage or a breach -of -contract action
 by the  building owner for failing to adhere to the contractually-required standard of
 performance.

 Indemnification Clauses - Many contracts contain  provisions requiring that the project
 designer  Indemnify  the owner for liability  arising out of the  performance of the
 professional services.  Indemnification clauses are highly complex and may be subject to
 differing interpretations in various states.   It is important for every contract to be reviewed
 for such clauses and that the scope of the indemnity be  carefully  defined  to avoid
 unintended liability for the designer.

 Tort fNeoliaence) Liability

 The second area of liability concerns the project designer's  failure to perform his or
 her work  In  accordance  with  the  standards of the profession.  If such failure
 occurs and persons are injured or property is damaged as a result, the project  designer
 may be sued in "tort." A tort is a legal wrong. The breach of a legal duty is often termed
 "negligence."  Negligence can arise from the project designer failing to property include
 methods in the specifications to protect the building structure and finishes or the people
within the building from harm.  Three examples will illustrate the potential problem.

Exampte A - The designer is retained to develop written specifications to remove sprayed-
on surfacing material in a gymnasium. The specifications call for placing only one layer of
4-mil polyethylene over the hardwood floor; as a result, in the course of removal the
polyethylene  leaks and the floor is severely damaged by water.  In this case the designer
could be accused of negligence for improper design of the system to contain the water.

Example B -The design contract requires the development of written specifications to
remove sprayed-on surfacing material in a multi-story building. The specifications neglect
to address proper isolation of the high-rise elevators;  as a result, fiber contamination
occurs on  floors above and below the work area.   The designer could be accused  of
negligence for a design that did not prevent fiber migration.

Example C-The designer is contracted to provide architectural and engineering services
to property remove ACM in a single-story  structure. The written specifications require the
placement of two layers  of fire-rated sheetrock over entrances and exits except the
decontamination unit.  If  a fire occurs and  people  are injured, the designer could be
accused of negligence for improper containment construction.

It is also important to note that compliance with regulations, although mandatory, is not a
defense  against negligence, if industry standards are more stringent.  Regulations are
minimum requirements.

Regulatory Liability

The  last area of project designer lability  concerns noncompllance with federal, state
or other regulations.  A first area of concern is compliance  with  project designer

 STUDENT MANUAL                                        AS8ESTO6 ABATEMENT PROJECT DESiQN

 accreditation requirements.  Not only must the project designer take an EPA-approved
 course and pass an examination, but he or she must also comply with state regulations for
 certification.   For example, In some states,  project designers are also required to be
 registered architects or engineers, or certified industrial hygtertsts.  In addition, regulations
 under the Asbestos Hazard Emergency Response Act, for example, carry severe penalties
 for noncompliance. including potential criminal liability.  In  the event that regulations are
 violated, the project designer may be subject to fines or penalties from various regulatory
 authorities.

 INSURANCE CONSIDERATIONS FOR PROJECT DESIGNERS

 Obtaining professional liability insurance is the normal method for a  professional such as
 an asbestos  project designer to secure protection from possible litigation  arising from
 negligence in performing  his or her professional activities.  Insurance is a risk-shifting
 mechanism to provide protection against catastrophic liability.

 Many owners require that all professionals involved in asbestos-related work  have liability
 insurance in order to  have some financial security for significant claims that may arise.
 Under certain state and  local  laws,  general  liability  Insurance In specified
 amounts Is  often required.

 A related aspect of risk shifting is the presence of indemnification clauses in  the contract.
whereby the professional is obligated to indemnify and defend the owner (and vice-versa)
against claims brought against the owner arising out of the professional's work. Insurance
may not always protect against this type of liability.  At the same time, however, project
designers need such insurance to  protect themselves against claims which  can be

                                                                              Pago 7
financially ruinous, and to provide for legal defense of any claims. While work done in
accordance with the applicable industry standard of care, the contract documents and
applicable regulations may ultimately shield the project designer from liability,  the
assumption of defense of a legal action by the insurance carrier,  or the dient (building
owner) who indemnifies the designer, is a significant benefit

It is obvious that insurance adds to the project designer's cost of performance and thus is
eventually paid by the owner, either on a pro-rata basts or, in many cases, dollar for dollar.
Due to the expense  of liability insurance,  many owners have  considered dropping
insurance requirements and many consultants have performed work without insurance.

The relative unavailability of professional liablity insurance in the recent past has resulted
in some asbestos professionals purchasing insurance without paying adequate attention
to whether risks  are covered or the strength or credibility of the carrier. Similarly, owners
are accepting insurance certificates  without analyzing  the coverage  being offered.
Changes in the  type  and scope of coverages offered by  the insurance industry must,
therefore, be  analyzed carefully to accomplish  the goal of insurance.   Rather than
protection against liability, insurance for some has become a "license to work*  in the
asbestos  industry.  However, insurance products have  become more available  for
professional activities and should be investigated.

 Insurance, also known as Errors and Omissions (E&O) Insurance to protect them
 against  negligence  In  the  performance  of  their  professional  services,
 Including developing the  specifications and drawings.  The mistake may take the
 form  of an inadvertent error (i.e., miscalculation of  area  square footage),  or  an
 unintentional omission (i.e., leaving an area that needs to be abated, such as a soffit, out of
 the design specifications).  E&O coverage is written  for specific professions.  Many
 professionals (architect, engineer, designer, etc.) have E&O coverage to protect them for
 their specific professions; however, asbestos-related professionals  may have difficulty
 obtaining  appropriate coverage due to the great risk for  loss in their activities.  If E&O
 insurance is desired by the asbestos professional, the coverage  must  be carefully
 examined, from a coverage, limits and cost perspective.

General liability insurance is another type of coverage that project designers need. It is
intended to serve as protection for events that occur during development and execution of
the project specification that do not involve pollution liability.  These can include slips and
falls, and nonpollution property damage. The drawback to this type of Insurance Is
that it will  likely contain a  pollution or  asbestos  exclusion, rendering the
policy essentially Ineffective  for asbestos-related claims.

Coverage Issues

It is important to understand the difference between general liability and professional
liability insurance from a coverage basis also.  In the past, general liability insurance has
been written on  an "occurrence" basis.  Under such a policy, if an incident "occurs"
while the policy  is in  force,  coverage Is afforded even If the actual claim  Is made
some years  later and even  If the  Insured Is no longer Insured by  the same
carrier.  As a result of the writing of this type of coverage, insurance carriers must defend
claims brought years  after companies are no longer insured by the carrier.   Particularly
with the  long latency period  of asbestos-related disease, occurrence coverage can result
in great losses to carriers who have not received premiums over a period of  time.  As a
result, several years  ago carriers  began adding exclusions to existing general liability
policies for asbestos-related  third-party claims and even changed the coverage form from
"occurrence" to "claims made" for both consultants (designers) and contractors as well.

As contrasted with general liability coverage, professional liability coverage has historically
only been written on a "claims made' basis.  Thus, E&O coverage for asbestos design
consultants,  as  well  as  architects, engineers, attorneys,  accountants and medical
professionals, will most likely be on a "claims made" basis and it may be difficult to obtain
appropriate coverage.

Under  a "claims made"  policy,  coverage  Is  provided for  claims that  are
brought while  the policy  Is  In  force.   In  certain  situations, a daim may also be
brought during an extended ("tail") reporting period after the policy has expired, which may
require an additional premium.  In switching coverage to a new insurance carrier, it Is also
possible to request 'retroactive* coverage for unknown claims prior to the new  policy.  For

-------
 STUDENT MANUAL                                         AS8ESTO6 ABATEMENT PROJECT DESIGN

 many risks, the difference between occurrence and claims made  coverage  is not
 significant since the liability-causing event is obvious, and claims are generally asserted
 shortly after the event occurs. However, injury caused by the release of fibers from an
 asbestos abatement project may not be detected for 20 to 40 years afterward. Thus, daims
 made coverage may not respond in such cases if (1) the insured changes insurance
 carriers before a claim is made, or (2) the carrier or insured terminates coverage under a
 policy, or (3)  the  carrier later  withdraws from the market before a  claim  is  filed.
 Nevertheless, it is likely that professional liability coverage in the future will continue to be
 written on a claims made basis,  and thus the insured must understand what is actually
 being purchased and whether the carrier wiH continue to service this market

 In addition to coverage issues, it  is mandatory that the insured read and understand the
 exclusions in its policy.  All  exclusions,  conditions and  definitions must be carefully
 analyzed.  For example, a general liability policy written for an asbestos project designer
 which includes a "pollution exclusion," excludes coverage  for any personal injury or
 property damage caused by a broad list of substances known  as 'pollutants."  Generally,
 asbestos is included on the list for project designers and, consequently, the policy provides
 no coverage for asbestos risks. Some professional liability policies require certain types of
documentation, or certain professional  accreditations.   All  policy  terms must be
understood.

 In addition to obtaining Insurance for professional liability, a designer may work with the
owner in developing insurance specifications for the contractors performing the  work.
Care must be taken in assuming this responsibility, since this is often excluded in the E&O
policy.  There are several  important considerations  in making an analysis of available
insurance coverage  or in specifying same:

       1 .     True  "occurrence"  coverage la available.  However, the terms of the
             policy  must be  reviewed carefully.   Some 'occurrence' policies have
             conditions or exclusions that negate coverage, or have "sunset* clauses
             which terminate coverage one, two or five years after the policy ends.  The
             name of the policy makes no difference.

       2.     The insurance certificate is only evidence of coverage; it provides relatively
             little  information of benefit to an owner or professional consultant  The
             policy itself must be reviewed.

       3.     The Insurance carrier must be very carefully evaluated.  Does the carrier
             understand the industry and is it committed to writing proper coverage?
             Again, the policy terms are important.

CONTRACTS FOR ABATEMENT WORK

Though the contract for the  abatement work is between the building owner and the
contractor, the designer is often involved  in the solicitation of  bids and selecting the
contractor. Some of the more  important contract issues with which the designer may be
involved are discussed below.

Typos of Contract Documents

Once a building owner has decided to begin an asbestos abatement program, the owner is
faced with many practical questions.  One of the first of these relates to contract documents.
Great care must be used in the selection of contract documents and clauses, since this will

-------
 STUDENT MANUAL                                       AS8ESTO6 ABATEMENT PROJECT DESIGN

 define the legal  relationship and responsibilities of the owner and contractor.   The
 American Institute of Architects (AIA) has developed a number of standardfced agreements
 for construction, but nevertheless advises users of the important legal consequences of
 these documents.  One typical contract used for abatement work is AIA 101, Owner-
 Contractor  Agreement Form  - Stipulated  Sum, a four-page  document which
 typically contains the name of contracting parties, the contract amount, the start and
 completion date and other general  data.   Other  standardized  forms also exist.
 Accompanying Form  AIA 101 is AIA 201, General  Conditions of the Contract for
 Construction.   This  is  a 19-page document  which contains  general contract
 requirements, sometimes erroneously referred to as "bolter-plate* language. Form AIA 201
 has been around  for many years. Its clauses have been frequently litigated and lawyers
 and facility owners are familiar with the normal interpretation placed on the language in
 AIA 201 . This provides for a degree of certainty, which is desirable. Of course, disputes do
 arise  under these clauses,  and the contract must be tailored to  the specific project.
 However, it may be easier for legal counsel and the facility owner and contractor to resolve
 differences  under familiar  contract language than  in the unknown areas of  a job
 specification on an asbestos abatement contract. Contract documents are covered in  more
 detail in the design workshop portion of this manual.

 The third document that will typically be  included, or referenced to, in  an asbestos
 abatement contract  is  the project manual or project specifications. Regardless of
 the size of the Job,  or whether It Is public or private, a written set of project
 specifications  Is a  must  for  any  asbestos  abatement  project.   Project
specifications will vary  in the  amount of detail provided  and the format, from one designer
to the next No two should be exactly alike because the specifications must be adapted to
the site parameters.  The fact that these project specifications are  site  specific and

therefore have not been subject to the  interpretations placed on  the standard
specifications,  makes  careful attention to  and interpretation  of asbestos  abatement
specifications critical   Frequently, design professionals give very strict interpretation to
these clauses  and are much  less permissive than in the interpretation of specifications
involving less hazardous activities.

SOME IMPORTANT ISSUES RELATED TO CONTRACT SPECIFICATIONS

Description of Work

One of the most Important Items In the written specifications Is the  work description.
Typically, if an  entire building is involved, the work description may not be a significant
problem. However, if a contractor is being asked to remove asbestos  in only a segment of
a floor of a building, for example, a serious abatement problem may exist.  When the
plastic barrier is removed, will  the "dean air* still be dean? Another problem is Illustrated
by the Job where the contractor was asked to remove friable material from beams over a
dirt basement  in a commercial  building.  The specifications  did  not call  for barrier
protection for the dirt  The contractor, fully in compliance with the specifications,  removed
the asbestos; however, in the process, it contaminated the dirt. The result  was that a
second abatement effort was required  for the removal of several inches of dirt in the
basement  This cost, quite unnecessary, was the result of inadequately prepared
specifications.  Of course, drawings are of great assistance in properly defining  job
boundaries and the scope of the specifications.

 Furniture. Fixtures and Equipment
  ASBESTOS ABATEMENT PROJECT DESIGN
Section XI - Lftgai and Insurance Consfctorafons
                          Pago 14
 Another issue that frequently arises is that of furniture, fixtures and equipment.  Most
 asbestos abatement projects require the removal and then  reinstallation of furniture,
 fixtures  and equipment.  The owner  should make  a realistic  assessment of
 whether salvaging of such Items, particularly fixtures, Is  feasible. The age and
 condition of the furniture and equipment must be assessed.  It will  only promote contractual
 disputes for  the owner to insist that a  contractor remove and  reinstall fixtures  and
 equipment which will be damaged or destroyed by the very process.  The owner  and
 project designer should not expect to engage in a "backdoor" renovation of the  facility, at
 the contractor's expense, by placing specification requirements on the contractor which are
 unattainable.

 Site Security
Site security is  another  issue that should be specifically addressed.  An unsecure
asbestos  abatement site  can  have  grave  legal  Implications.  Of course, any
construction site can be dangerous, but  an  unmonitored asbestos abatement site is
particularly hazardous. The issue of whether  security must be maintained on a 24-hour
basis is also one which must be addressed. Again, this is an area where  more attention
must be given if only one area of a building is being abated while  other areas are
occupied.  If an entire building can be  isolated, security is a much  easier  process.
Certainly, the regulatory warning signs required by OSHA are important; however, these
should be viewed as a minimum warning and  further warnings or security are frequently
necessary.

Equipment Selection

Each owner must participate,  if only through  his  project designer, in equipment
requirement decisions on an asbestos abatement project. The decision about the number
of air filtration devices, what type of respiratory protection equipment is required, what type
of dothing is sufficient, what number of HEPA vacuum units are necessary  and other
similar equipment requirements is very important to the success and safety of the job.
From  a  technical  and  legal  standpoint,  It  can  be effectively argued that
"state-of-the-art" equipment should  be employed.  OSHA and EPA requirements
again should be viewed as minimal requirements.  If one is not going to employ •state-of-
the-art* technology, that decision must be justified.

Insurance Protection for the Building Owner

A  major issue for asbestos abatement contractors, as well as design professionals, is
insurance.  At present, the insurance 'crisis* is easing and contractors who have not been
able to obtain liability  insurance now have it more readily available.  From the owner's or
contractor's perspective, it is first important to understand what the insurance requirements
are. The first issue Is who must be protected. Generally speaking, the owner will want to
require protection for itself and its employees, the contractor and  its employees, and third
parties.  This will  mean that the owner will wish to be an additional  insured  under the
contractor's policy and to be furnished a certificate of insurance as well.  It is important that
the certificate of insurance  specify the types of  coverage afforded.  However, since the
certificate  of insurance is only evidence of coverage,  it is not complete and the owner
should request a copy of the contractor's insurance policy. This  is particularly  true since
asbestos and pollution exclusions can appear  in such policies. The owner's legal or

 insurance advisors  can play an important role  in ensuring that  proper coverage is
 obtained.
 Insurance must protect the insureds from both bodily injury (to persons) and property
 damage claims.  While this is standard in general liability policies, bodily injury and
 property damage claims may be excluded due to an exclusion of coverage for asbestos- or
 pollution-related claims. Therefore, the owner must be sure that H is protected from the real
 hazards presented by asbestos abatement  Of course, it is necessary to insure against the

 that coverage continue after the contract is completed.  "Completed operations" coverage
 ensures that if the contractor fails to completely abate the asbestos problem and the owner
 initially fails to discover the contractor's oversight the owner will nonetheless be protected
 if a claim arises after completion.  Also related to this issue is the need to determine
 whether the insurance is "claims made"  or "occurrence" coverage. These  concepts were
 covered earlier in the  discussion on insurance for the project designer.  Generally

Bonding
While some facility owners are now requiring bonds from professional firms, bonding is
usually required only from the contractor, and the project designer's interest in this topic is
that of the building owner's.  The requirement for bonding is generally included in the
contract documents.  The project designer, in conjunction with legal counsel, may be
called upon to provide guidance on the types and amounts of bonds that are necessary for
the project.   Traditionally, two  types of bonds have been required in  the construction
industry to protect the owner or lender against the contractor's financial default:

       •  Payment Bonds - under which a surety company agrees to pay for labor and
         materials supplied to a project in the event the contractor fails to do so; and

       •  Performance Bonds - under  which a  surety company  agrees to complete
         performance of a project if the contractor fate to do so.

Abatement contractors who have had their Insurance  cancelled or not renewed experience
difficulties in  obtaining bonding.  Bonding companies  rely  on  the financial ability of the
principal (the contractor) to respond to claims under payment and performance bonds.  If a
contractor is not insured against catastrophic liability,  the financial  underpinnings of the
company can be weakened  and  the bonding company becomes apprehensive over
issuing bonds.  In  a similar  vein, lenders are reacting adversely to the problems of
insurance and bonding of such companies.  Lenders  are advising  contractors who find
themselves In such positions that lines of credit will not be renewed for the same reasons
given by the bonding companies.

 In the recent past, the difficulty encountered  by asbestos abatement contractors in
 obtaining bonding was severe.  For reasons similar to those which caused the asbestos
 abatement Insurance crisis,  many contractors were unable to obtain sufficient bonding
 and. in some cases, any bonding. In  addition to the general underwriting concerns about
 the contractor's financial and technical ability to  perform the work, another reason some
 bonding  companies were unwilling to write bonds for asbestos abatement work relates
 directly to liability insurance problems.   Because  the  abatement  contract often has
 requirements for the contractor to obtain and maintain certain liability insurance coverage
 on the project, the bonding companies fear that If the contractor has insurance problems.
 such as improper coverages or cancellation during the policy period, the potential loss that
 may otherwise be  covered by liability insurance might be covered  by  the  contractor's
 performance bond.  Though insurance and bonding are easier to obtain  now than in  the
 late 1980s, the expense remains relatively high and careful attention must be paid to  the
 quality of coverage obtained, as discussed earlier.

 While the traditional concepts of bond underwriting may  not be applicable to project
 designers, it is nevertheless useful to understand them. The primary considerations of  the
 bonding  company in determining whether to bond  a contractor are the  ability of the
 contractor to perform the work and the contractors financial  ability. A proven track record
 of successfully-completed projects,  without ensuing litigation, is very helpful to the
 contractor in demonstrating  to the bonding company its  ability to  perform the work.
 Financial stability is important not only  with respect to the contractor's ability to  perform the
work, but also its ability to satisfy its indemnity obligation to the  bonding company in the
event a loss Is suffered under the bonds.  Unlike insurance, a payment or performance
bond gives the bonding  company the right to recover contract balances if losses are
sustained by it under the bond. A somewhat more intangible, yet important factor, is the

contractor's good character. Despite satisfactorily proving all of these items, however, a
contractor may still not be able to obtain sufficient bonding in today's market  In such
events, an owner may waive or refuse bonding requirements or arrange other contractual
mechanisms to assure payment or performance.

There  are  numerous legal considerations involved  in the evaluation of insurance and
bonding coverage. The cost of insurance for asbestos abatement is significant, and if such
expense Is going to be undertaken, the coverage obtained should be satisfactory. While
there are  no easy solutions in  this decision-making  process,  it is mandatory that
contractors, consultants and owners undertake to become knowledgeable purchasers of
insurance.

The shift in the types of coverages written for the contracting industry from occurrence to
claims made, and the difficulty in  obtaining bonds have placed greater emphasis on the
contractor's commitment to the performance of work in a quality manner, the carrier's
commitment to continuing to insure asbestos abatement contractors, and the quality of the
carrier's  coverage and insurance program in  general.  This makes the  process  of
purchasing Insurance more complicated, but a  thorough review  of the considerations
outlined  above  will greatly assist the  contractor,  consultant or owner in making a
knowledgeable choice.

Supervision and Training

The heart of any asbestos abatement project is not the equipment, although the equipment
is important, or the physical project requirements, although they are  vital too. The heart of
the project is the care and skBI exercised  by the workers who remove the asbestos-

 containing materials. If this occurs in a professional manner, the owner can expect a good
 result If the work is sloppy, good equipment will not save the job.

 From the owner's perspective. It is vital that the contractor's project superintendent be an
 experienced asbestos abatement worker.  He or she must have had experience on various
 projects and under various conditions.  The owner should require documentation of the
 experience. It will behoove the owner to check on the quality of the preceding projects.
 The superintendent is the key to the work.

 Many projects are  sufficiently extensive to require a project superintendent and  foreman.
 The latter person typically will be in the containment area actually supervising the workers
 while the superintendent may be in and out of the area at various times.  If a foreman is
 required, he or she should also be experienced and able to instruct the workers on site
 and personally supervise actual  preparation, removal and clean-up activities.   It  is
 desirable to contractually require that both  of these positions be filled by  qualified
 individuals.

 If the  removal project is being conducted in a school, abatement workers and supervisors,
 as well as inspectors, management planners and project designers, must be trained  In
 accordance with  AHERA regulations.   Under  regulations  promulgated  by  the
 Asbestos In Schools  Hazard  Reauthorlzatlon Act (ASMARA), AHERA training
 requirements are being  extended  to  commercial and  public buildings.  When
those regulations  come  into effect, it will not only be recommended, but a regulatory
requirement, that asbestos abatement workers and supervisors receive training from an
approved training provider and pass the required exam.

From a legal standpoint  it is critical that records be kept to document that training was
given to each worker.  The facility owner, via the project specifications, can reserve the
right to inspect these records and retain copies.  In fact, the owner may wish to maintain a
complete file on all workers who worked on the project This will avoid the problem of the
contractor going out of business later and an asbestos daim arising by an employee
against the owner many years thereafter based on an alleged failure to warn.
The facility owner needs to maintain permanent records on all phases of the
project, from Inspection, to design and  through abatement  It is  not enough to
maintain these records for a few years.  Asbestos disease latency periods  may extend 30
or more years beyond the work date.  These records should be stored and maintained
permanently. The required records should be specified in the project specifications, and
responsibilities for development and maintenance of records dearly defined.

Adequate Time for Job Performance

One of the most difficult problems in asbestos abatement work is that of time. Once the
owner has decided to conduct an asbestos abatement program, he is virtually always in a
hurry. Many programs are specified with very snort time limits of two to five  days, and work
often must be performed at night, or on weekends or holidays.

To avoid contractual disputes, it is desirable for the owner to specify enough time to allow
the project to be completed in a competent manner. Questions of access to the site, other
contractors who  may be working or  waiting for notice to proceed, and  the  owners'

 employees  presence at the site must be considered.  Generally speaking, qualified
 abatement contractors will begin work quickly once they are notified to proceed.  Owners
 are frequently critical of late starts that can result in late finishes.  It may, therefore, be in the
 owner's interest to provide  some liquidated damages for a  late start as a means of
 emphasizing to the contractor that the start date is important  However, most frequently this
 issue is addressed by completion date requirements and liquidated damages for failing to
 complete the work on time. At the same time, owners are frequently guilty of not providing
 the site at the time specified, or delaying the work themselves, or changing the scope of
 work.  This may result in difficulties for the contractor in completing this project or with
 scheduling other work.  The resolution Is to cooperatively come up with a time
 for  the project which  will  be realistic  both  In  length  and  In  calendar
 placement for the owner and the contractor. The project designer must bring his or
 her experience to bear on this issue.

 As to delay damages, many owners choose to use liquidated damages as a vehicle to
 make sure that contractors finish the job in the time specified. If extensive renovation work,
 following removal, or other important use of the facility is  contemplated,  liquidated
 damages may not suffice to cover the actual damages.  In these instances, owners may
 find that they are limited to damages which are less than that to which they are entitled.
 However, liquidated damage provisions are intended for use  where the actual computation
 of damages is not possble.  Most courts wifl enforce liquidated damage provisions on the
 basis that the reason for specifying liquidated damages  is the uncertainty of calculation of
actual damages.  The amount of liquidated damages must be determined on a reasonable
basis, since bonding companies will often limit the daily amount that can be imposed on
the contractor.

         of Asbestos-Contain'tna Waste
Another important issue is that of materials handling and disposal. The asbestos material
must be properly containerized, labeled, and shipped to an approved dump site.  The
contract or specifications should specify each item with particularity.  The owner should
obtain a copy from the contractor of the waste shipment record or manifest required by the
EPA NESHAP. This document must be given to the landfill operator by the waste hauler.
The owner must receive a copy from the landfill operator within 35 days after the waste is
received.  This provides a means for the owner to verify the waste arrival at the landfiH. it
will be desirable to have  an inventory of the drums  or bags to compare to the waste
shipment record.  This kind of attention to detail will eliminate possible claims of improper
toxic substance dumping.  The disposal site must also be chosen carefully, depending on
the character of the waste (solid/liquid, asbestos/other hazardous substances, etc.). It Is
also prudent to make sure that the materials are property  unloaded  and handled at the
disposal site.

Selection of Qualified Contractors
Another problem peculiar to public work is the requirement that the public authority accept
the lowest bid, or lowest responsible bid. The owner must  determine the best way to
satisfy this requirement and stHI engage qualified asbestos abatement contractors.  One
method of addressing this problem is to determine whether the applicable laws permit the
public agency to prequallfy contractors. Prequalification requirements can consist of
various criteria.  These may Include experience either with asbestos abatement
or  with the particular type  or size of  project  being  bid, training, formal
education (for Instance, attending  seminars),  Insurance, bonding, and a Job

 Inspection.  A public agency must determine the best way to hire a contractor and still
 comply with its legal obligation  to accept the lowest bid, or the lowest "responsible'' or
 lowest 'responsive' bid, under applicable law.

 Frequently, an asbestos  abatement contract may be coupled with other renovation or
 reinsulatJon work.  It is virtually always necessary to have some replacement materials or
 structures for the asbestos-containing materials or structures that are removed. A decision
 must be made whether to have the asbestos abatement contractor function as the general
 contractor, or as a subcontractor under the general contractor in charge of the entire
 project.  The general contractor  is responsible for coordination of the various trades that
 may be involved. In a particularly hazardous project,  it may be necessary to contractually
 require some training of other trade workers regarding the dangers of asbestos or of the
 asbestos removal. Certainly, conferences of the trade superintendents throughout the job
 is desirable and strict security is most important in a job of that type.

 Using a general or prime contractor with an asbestos  abatement subcontractor does raise
 several issues. A problem can arise if the asbestos abatement subcontractor is unable to
 complete the work or is thrown off the job for some reason. In most instances, the prime
 contractor will not be qualified to complete the work himself.  In these instances, the owner
 may wish to reserve the right to select a substitute asbestos abatement subcontractor using
 the same criteria used in the original selection. Another issue that can arise is the ability of
 the general contractor to obtain adequate insurance and bonding for asbestos abatement
work.  Most often, these activities are excluded from the general contractor's insurance and
 bonding  programs.  This  may necessitate  using the abatement contractor as a prime
contractor, or having separate contracts for abatement and renovation work.

One final note is that of the completion of the job by clearance testing.  The contract
should  contain a combined  requirement  of clean surface* and achieving
clearance  air standards, as well as specifying  the  methods to be used.  Itis
possible to have acceptable air monitoring results within the abatement area, and still have
dangerous levels of asbestos-containing materials present within the facility.  It is important
to require that all surfaces in the work area be dean upon visual inspection, prior to
clearance testing.  Therefore, the owner  or his representative must be sure that the
contractor has thoroughly removed and cleaned up all material, and that the airborne
asbestos  fiber concentrations  meet the clearance standards  established in the
specifications and applicable  regulations,  utilizing  the specified procedures  (e.g..
aggressive sampling, PCM vs. TEM analysis, etc.).

Protect Manaoer and Air Monttorlna Personnel
The qualifications and integrity of the project manager or air monitoring professionals are
vital.  They should be qualified and experienced.  There have been a few instances of
falsified  tests  reported.   An  Important  consideration  Is to  have  project
management  and  air  monitoring  performed  under  a  separate contract
between the  owner and the project  management or  air monitoring firm. An
owner does not normally want to have a turnkey* contract where his abatement contractor
supplies the project management and the air monitoring, unless the owner has separately
determined the qualifications of the project management or air  monitoring firm being
engaged by the contractor.  In school  buildings covered by AHERA regulations,  an
independent firm is required to conduct clearance testing. Other laws must be consulted

 as weH.  The owner may wish to have the project management or air monitoring paid for as
 part of the abatement contract; however, this must be weighed against obtaining his own
 project management or air monitoring contract with a separate firm or person.  A number of
 owners seek to save money by having the contractor take either progress samples or even
 clearance samples,  using the contractor's employees.  Since  air  monitoring data is so
 critical in determining  proper performance and  perhaps  defense of any claim, this
 procedure is discouraged.

 CONCLUSION

 The project designer and owner must be aware of legal and insurance issues involved
 with abatement work.  Contractual issues are particularly important  since the project
 designer must be concerned not only with its contract but often in developing the contract
 and project requirements between the owner and contractor. The project designer must be
 careful to avoid areas where he or she  is not trained or experienced, so as to avoid being
 held liable to the owner.

 Both legal and insurance  issues are complex.   The project designer and owner should
 work with legal counsel and insurance advisors who  are experienced with asbestos
 abatement work.  This  will help avoid problems before, during and after the asbestos
 abatement  project

  FEDERAL, STATE AND  LOCAL REGULATORY  REQUIREMENTS
INTRODUCTION

The federal agencies which oversee regulations pertaining  to asbestos-containing
materials (ACM) include  the Environmental Protection Agency (EPA), the Occupational
Safety and Health Administration (OSHA), the Department of Transportation (DOT), the
Consumer Product Safety Commission (CPSC). the Food and Drug Administration (FDA).
and the Mine Safety and Health Administration (MSHA).  This section will focus on the
EPA.  OSHA and DOT regulations which have the greatest impact on the design and
execution of an abatement project.   This section will conclude with a discussion on
common variations between federal, state and local regulations.

The EPA traditionally has jurisdiction over issues that affect air. water and land. Following
this trend for asbestos, there arc EPA  regulations which focus on minimizing the release of
asbestos fibers  into the environment and accreditation of  the work force. For asbestos-
related issues.  EPA also  regulates schools.  These regulations  require  inspection,
assessment and control of ACM In schools conducting kindergarten through twelfth grade
classes.  OSHA regulations focus on worker health and safety issues including procedures
for  performing work, established permissible exposure limits for asbestos workers, and
requirements for protective equipment when working with ACM.  DOT regulates  the
packaging and  shipping of asbestos-containing  materials including waste generated
during an abatement project.  States,  counties and cities promulgate  and enforce a wide
range of asbestos regulations which must be as stringent as the federal regulations,  and
which also must be incorporated into the abatement project design.

notification requirements, asbestos emission control procedures, and ACM waste disposal
practices  and records.   In some regions the administration  of  NESHAP has  been
delegated to the state level, in which case the regulation may be more stringent or the
interpretation and enforcement may vary from  the federal authorities.  In any case, the
NESHAP  administrator is a federal or state  authority with  primary responsibility for
regulation of asbestos abatement associated with building demolition or renovation.

Applicability - The revised  NESHAP regulation added or amended some definitions which
are key to understanding the applicability of the regulations.  These include the following:
       "Regulated asbestos-containing material (RACM)"  means (a) Friable
       asbestos material; (b) Category I nonfriable ACM that has become friable;
       (c) Category I nonfriable ACM that will be or has  been subjected to sanding.
       grinding, cutting, or abrading; or (d) Category II  nonfriable ACM that has a

       high probability  of becoming or has  become crumbled,  pulverized, or
       reduced to powder by the forces expected to act on the  material in the
       course of demolition or renovation operations regulated by this subpart.

       "Renovation" means altering a facility or one or more facility components in
       any way.  including the stripping or removal  of  RACM  from a facility
       component.

       "Demolition" means the wrecking or taking  out of  any load-supporting
       structural member of a facility together with any related handling operations
       or the intentional burning of any facility.

       "Category  I  nonfriable asbestos-containing  material (ACM)" means
       asbestos-containing packings, gaskets, resilient floor covering, and asphalt
       roofing products containing more than one percent asbestos as determined
       using  the method specified in Appendix A, Subpart F. 40  CFR Part 783.
       Section 1, Polarized Ught Microscopy.

       "Category  II nonfriable ACM" means any material, excluding Category I
       nonfriable ACM, containing more than one percent asbestos as determined
       using  the methods specified in Appendix  A. Subpart F. 40  CFR Part 763.
       Section 1,  Polarized Light Microscopy that, when dry.  cannot be crumbled,
       pulverized, or reduced to powder by hand pressure.

       "Friable asbestos material' means any material containing  more than one
       percent asbestos, that, when dry, can  be crumbled pulverized, or reduced to
       powder by hand pressure.

       •Adequately wet* means to sufficiently mix  or penetrate with liquid to prevent
       the release of particles.  If visible emissions are observed coming from the
       material, then it is not adequately wet.  However, lack of visible emissions
       alone is not sufficient evidence of being adequately wet.

       "Visible emissions" means any emissions which are visually detectable,
       without the aid of instruments, coming from RACM or asbestos-containing
       waste  material.
Before conducting  a renovation or  demolition activity,  building owners  or

operators  must thoroughly Inspect the facility or part  of the facility where the

activity  will  occur  for  the  presence  of asbestos,  Including  friable,  and

Category I and Category  II  nonfriable ACM.



If a facility contains  the following amounts of RACM,  it is subject to NESHAP regulations for

demolition and renovation activities which disturb the ACM:

       •  260 linear feet (80 linear meters)

       •  160 square feet (15 square meters)
       •  35 cubic feet (1 cubic meter)
       •  Combined additive amount during a calendar year equals or exceeds any of the
         above amounts
For demolition projects that wilt not involve more than the stated amounts of material, the
only action that is required is notification.  Notification  must be given to the NESHAP
administrator prior to building demolition.  For renovation projects that disturb less than
the stated quantities, NESHAP does not apply.

Notification Requirements - The facility owner or contractor performing the demolition or
renovation project must notify the NESHAP administrator in writing. The notification can be
delivered by U. S. mail, commercial delivery service or hand delivery.  Notification must be
postmarked or delivered ten days before renovation, demolition or any other activity begins
that would disturb ACM.

For combined additive renovations projected to occur in the  coming year, notification must
be postmarked or delivered ten days before the end of the calendar year preceding the
year during which the work will be done.  For emergencies, notification must be given as
soon as possible but no later than the following working day.

NESHAP  notification requirements are  extensive, including the following:   name and
address of the building owner or manager; description and  location  of the building;
estimate of the approximate amount of friable ACM present in the facility; scheduled start
and  completion dates  of  ACM removal;  description  of planned  removal methods;
procedures to be used to comply  with the  requirements of this  regulation; and name,
address and location of the disposal site.

It should be  noted that specific  notification requirements may vary depending  on  the
interpretation  of NESHAP requirements by a state or region. Therefore, a designer should
contact the local NESHAP administrator for detailed instructions. An example notification
form is provided in Figure XI1-1.

Asbestos Emission Control Procedures - Regulated asbestos-containing material
must  be  removed  from a facility  before  any  demolition  or renovation
activities  occur  that would  break up,  dislodge or  similarly  disturb  the
material.

The following  exceptions are allowed during demolition and renovation:
       • Category I nonfriabte ACM that is not in poor condition, is not friable and will not
        be subjected to sanding, grinding, cutting or abrading  does not  have to  be
        removed

       • ACM that is on a facaity component and is encased in concrete or other  similar
        material and is adequately wet when exposed does not have to be removed.

       • ACM that was not accessible before testing and was not discovered until after
        beginning the demoition or renovation project does not have to be removed.
        (ACM exposed during  demolition or renovation must be treated as ACM waste
        material and kept adequately wet at all times until disposal.)

         pulverized or reduced to powder during demolition or renovation does not have
         to be removed.  If a Category II nonfriable ACM is damaged and becomes friable
         during demolition or renovation, then it must be removed.

Building  components covered with  ACM can be  removed in sections  as long as all
exposed  RACM is kept adequately wet during cutting or disjoining operations and lowered
to ground level without disturbing the  ACM. The ACM on the components can be wrapped
and sealed in a leak-tight material such as 6-mil polyethylene or stripped in a contained
area using appropriate work practices.

RACM must be kept adequately wet during removal operations and carefully lowered to
the ground floor.  Material being stripped or removed more than 50 feet above ground must
be transported via leak-tight chutes or containers. Exceptions from wetting ACM because
of damage  to electrical equipment or other systems must be obtained  in writing from the
NESHAP administrator.  If the RACM is being removed from a  work  area with freezing
temperature conditions. It does not have to be kept wet. However, temperatures must be
recorded at the beginning, middle and end of each work day. These temperature records
must be maintained for two years.

In addition to these control procedures, there is a requirement that there must be a foreman
or management-level person trained  in  the provisions of NESHAP on  site  during
renovation or demolition activities. This person must receive refresher training every two
years and evidence that the required  training has been completed must be posted on site
and available  for inspection by the EPA or delegated agency. Training topics must include

 control procedures for removal and demolition, waste disposal work practices, reporting
 and recordkeeping, and asbestos hazards and worker protection.  EPA will recognize valid
 accreditation of an AHERA asbestos abatement contractor/supervisor as satisfying the
 asbestos NESHAP training requirements.

 ACM Waste Disposal Practices and Records -The NESHAP regulation explicitly slates
 that no visible emissions shall be generated to the  outside air during the  collection or
 disposal of asbestos-containing waste material.  The RACM must be adequately wetted
 prior to removal and sealed or wrapped in leak-tight  containers while it is still wet.  The
 containers holding asbestos waste  must be  labeled in accordance  with  OSHA
 requirements [29 CFR 1926.58 (k)(2)].  If the containers are transported off the facility site,
 they must be labeled with the name of the waste generator and the location  at which the
 waste was generated (see also DOT labeling requirements).

 All regulated asbestos-containing waste  material must be deposited as soon as practical
 by the waste generator at a site that meets EPA requirements for operation as  a disposal or
 conversion facility. Owners and operators must maintain waste shipment records similar to
 the example in Figure XII-2 including generator, local NESHAP administrator, quantity of
 waste,  disposal site operator and location, date of transport, transporter, and certification.  If
 the generator does not receive a signed  copy of this record back from the waste disposal
 facility within 35 days, the generator must attempt to determine the status of the shipment.
 If the paperwork has not  been received within 45 days, the generator must report the
 situation to the local NESHAP administrator.   The  NESHAP regulation also Imposes
 several requirements on operators  of disposal facilities which are not covered in this
discussion.

 EPA Regulations Regarding Asbestos In Schools

 Several important legislative and regulatory actions have affected how public education
 agencies manage and respond to asbestos-containing materials (ACM) in schools.  The
 1982  'Schools Rule* in 40 CFR Part 763 required all schools to conduct inspections for
 friable ACM and to notify workers and parents of its location. Congress provided federal
 funds, in the form of loans or grants, to schools to control ACM through the Asbestos
 School  Hazard Abatement Act (ASHAA)  in  1984.   In the 1986 Asbestos Hazard
 Emergency Response Act (AHERA), Congress required EPA to promulgate regulations
 which further addressed the identification, evaluation and control of ACM in schools.  The
 AHERA regulations, 40 CFR Part 763, Subpart E, became effective December 14, 1987.
 ASHAA was  reauthorized in  1990 as  the Asbestos School Hazard  Abatement
 Reauthorization Act. or ASHARA, which extended the availability of federal funds to
 schools through  1996.  This Act  also  requires extension of accreditation and
training requirements which were originally Intended for work  In  schools to
Include Inspectors, designers, contractor supervisors and abatement workers
performing asbestos-related work  In public and commercial buildings.

AHERA Regulations
Local education agencies (LEA) affected by AHERA were required to perform inspections
to identify friable and nonfriable ACM, evaluate the condition of the ACM and develop a
management plan outlining a control program. Trie  initial inspection and management
plan requirements were to have been completed by May 9.  1989.  All public and private
nonprofit elementary and secondary schools must comply with AHERA, and each LEA
must have  a designated  person  to  coordinate inspection,  management planning,
operations and maintenance, and  response actions. The AHERA regulations supplement
but do not supersede any requirements of OSHA or NESHAP.

Below is an  AHERA overview for  the asbestos abatement project designer on a topic-by-
topic basis.  The requirements  which are not likely to directly  affect designers are
condensed.   If performing other  asbestos-related tasks  in a school building, one must
acquire  a much more thorough understanding of AHERA regulations than this summary
provides.

Inspection - AHERA requires accredited inspectors, those who have  successfully
completed an EPA-approved course, to identify all asbestos-containing building materials
(ACBM) in the school and certain exterior materials.  AHERA divides ACBM into  three
categories-surfacing material, thermal  system insulation,  and miscellaneous.   The
inspector must determine friability by touching all suspect ACBM.

Sampling and Analysis - LEAs can assume any or all suspect material is ACM. Otherwise,
a minimum of three to seven samples is required for characterizing different-sized areas of

 areas. Although the inspector must estimate the quantity of suspect ACBM to determine
 the correct number of samples, this number may or may not be reliable for design
 purposes.  Sample analysis is  by polarized  light microscopy and must be done by a
 laboratory which is certified by the National Voluntary Lab Accreditation Program (NVLAP),
 directed by the National Institute of Standards and Technology (NIST).  If any one sample
 of a material is determined to be greater than one  percent asbestos  using AHERA
 methodology, then the material is ACM. The designer should always check the laboratory
 results in the inspection report to determine if further surveying, sampBng and analysis are
 necessary prior to abatement design.

 Assessment - An AHERA inspection report should assess the condition of ACBM found.
 The assessment  should determine if the condition is good, damaged,  or  significantly
 damaged; the potential for future damage; and preventive measures which could be taken.
 Remember that  conditions may have changed  since an initial AHERA inspection in 1987-
 1988 or subsequent reinspections. which is another reason for carefully reviewing data
 prior to developing a specification.

 The Management Plan - The management plan is a dynamic document which rates the
priority of response actions to the condition of the ACBM found, describes the response
actions to be implemented, and is updated as actions occur. The management plan takes
risk of exposure, cost of response, and LEA budget into account in recommending how to
control and manage ACBM. The main criterion is that the response  action must protect
human health and the environment.   The  LEA is responsible  to implement the
management plan  in a timely manner.

                                        Section XII - F«d»fri. State and Coed Regulatory
Notification - LEAs must notify the parent-teacher organization and school workers of the
availabiBty of the management plan for their inspection.

Training - Custodial and maintenance employees who work in school buildings where
ACBM is present must be properly trained, and the LEA must notify short-term workers,
such as telephone and electric workers, of the location of ACBM. Additionally, inspectors.
management planners, response workers and supervisors, and project designers must all
receive EPA-accredited training.  Project specifications should include the requirement that
property trained and accredited personnel be used, and should require documentation of
all certifications.

Response Actions  -AHERA defines five response actions which LEAs can employ.
Removal, encapsulation,  enclosure, repair, and operations and  maintenance are all
allowed in certain situations.  Damaged or significantly damaged thermal system insulation
ACBM must  be repaired and maintained in undamaged condition. If  repair is not possible.
then material must be removed.  This is the most stringent AH ERA response requirement.
OSHA and NESHAP regulations must also be followed during school asbestos response
actions.  Enclosure,  encapsulation, removal,  and  responses to  major fiber  release
episodes in schools  must all be designed by an accredited project designer.

Clearance  Monitoring -AHERA defines specific clearance requirements for school
response actions. These are discussed  in detail in the section on  air sampling. Using
transmission electron microscopy (TEM) analysis, clearance can be achieved two ways.
Either (1) the average of five air samples taken inside the project  area is less than 70
structures per square miHimeter, or (2) five air samples taken inside and five samples taken
outside the project area are not significantly statistically different as  determined by the Z-

 allowed for projects which do not exceed 160 square feet or 260 linear feet of ACBM. In
 this case, fiber concentration for each of five samples must be less than or equal to 0.01
 fibers per cubic centimeter.

 Periodic Surveillance and Reinsoection - The rule requires periodic surveillance  and
 reinspection to monitor asbestos-containing  materials left in schools. Periodic surveillance
 requires checking these  materials every six months  to determine  if its condition has
 changed since the last inspection  or surveillance.  In addition, schools must have an
 accredited inspector  relnspect and reassess the condition  of  remaining asbestos-
 containing materials every three years  and determine  if  the condition  of the material
 requires new response action activity.

 Many AH ERA  requirements are considered  "state of the art" for the industry and as such
 are employed  in work outside schools.  There is no current law requiring inspections and
 management  plans for public and commercial buildings.  However,  1990  ASHARA
 included a requirement  that EPA write regulations to  extend  the AHERA training
 requirements to cover asbestos work in public and commercial buildings. Prior to the
 ASHARA deadline of November 28,1992, EPA's Office of Prevention. Pesticides and Toxic
 Substances published Interim  Guidance  on ASHARA  Requirements.   In  a  letter
 accompanying  the document, EPA explained that they would not be able  to fully address
significant ASHARA issues by the statutory deadline. However, the guidance document
stated that after November 28, 1992, all persons inspecting for asbestos or designing or
conducting response actions in public  and  commercial buildings shall be accredited in
accordance with AHERA training requirements. EPA interpreted "public and  commercial

 Worker Protection Rule

Certain employees of state and local governments are not covered under the OSHA
worker protection standard (29 CFR 1926.58) discussed later in this section. The purpose
of the EPA Asbestos Abatement Projects; Worker Protection; Final Rule is to extend the
OSHA worker safety guidelines to these government employees, especially those who
perform asbestos abatement work. The Worker Protection Rule. 40 CFR Part 763 Subpart
Q, became effective March 27.1987. and Is currently under revision.

When enacted, the rule was essentially  the same as the OSHA regulations in 1987. It
provided for an exposure limit, exposure monitoring and recordkeeping. regulated areas.
worker protection devices and facilities, medical surveillance, hazard communication, and
notification requirements.  However, the  rule has not been amended as have the OSHA
standards  on  multiple occasions since  1987.   Thus,  there are  currently many
discrepancies. Some of the most important differences are listed below.

'Employer' Definition - In order to protect state and local government employees, the rule
states that 'employer'  means  the public department, agency,  or entity which hires an
employee.  The term includes, but is not limited to, any state, county, city, or other local
government entity which operates or administers schools, a department of health or human
services, a Ibrary, a police department, a fire department, or similar public service agency
or office.

Notification - Under the Worker Protection Rule, an employer must notify the appropriate
EPA Regional Asbestos Coordinator in writing at least ten days before starting abatement
work.  The exceptions to this are emergencies, in which case notification is required within
48 hours, and projects involving abatement of less than three linear feet  or three square
feet of asbestos-containing material.  Also, if NESHAP notification (which is required for
demolition and renovation projects which disturb asbestos-containing material) is made
ten days before work begins, and the NESHAP notice clearly states that some of the work
will be performed by employees covered under the rule, then additional notification of the
Regional Coordinator is not required.

Excursion Limit - Section 763.121 (c) states a permisstole exposure limit (PEL) of 0.2 fiber
per cubic centimeter of air (fibers/cc). on  an eight-hour  time-weighted  average basis.
However, there is no excursion limit written in the worker protection rule as there is in the
current OSHA standard.   In  the  OSHA standard, the excursion limit is  a short-term
exposure limit of one fiber  per cubic centimeter average over a 30-minute time period.

Small  Projects - Section  763.121  (eX6)(H)(iii)(B) provides employers no exception for
small-scale, short-duration projects in  the (e) Regulated Areas  requirements.  (Currently,
this still resides in Appendix B of AHERA.) The Worker Protection Rule contains no parallel
to Appendix Q of the OSHA standard for regulating such activities. Appendix  Q describes
several types of small-scale, short-duration projects and the appropriate safety  measures
and engineering controls for use during these types of projects.

San fl/irf Phasfiout Rule
The EPA published Asbestos: Manufacture, Importation, Processing, and Distribution in
Commerce Prohibitions; Rnal Rule in the Federal Register on July 12, 1989. The purpose
was to 'prohibit, at staged Intervals, the future manufacture, importation, processing, and
distribution in commerce of asbestos in almost all products." Commonly known as the Ban
and Phaseout Rule, this section of 40 CFR 763 became effective August 25, 1989, except
for the information collection requirements which  have not yet been approved.

However, on October 21, 1991, a Federal Appeals Court sent the rule back to EPA and
effectively suspended the rule except for those products which were out of production prior
to July 12,1989.  The court held that the  EPA did  not properly consider less burdensome
alternatives to banning the products in these stages. Specifically, the court maintained that
the EPA did not evaluate the toxidty of likely alternatives to asbestos-containing products.
As of this writing, the EPA Is considering Its response to this ruling.

For information  purposes, the following is a summary of many of the products that would
have been affected in each stage of the Ban and  Phaseout Rule:

       Stage 1:  Felt products, corrugated and  flat A/C  sheet, floor  tile, and
                clothing;
       Stage 2:  Original equipment drum brake  linings and disc brake pads,
                clutch facings, automatic transmission  and other friction
                components,  and beater-add and sheet gaskets (except in some
                industrial uses);
       Stage 3:  Roof  and other coatings, paper products, brake blocks, after-
                market brake linings and pads, and A/C pipe and shingles.

 The rule stated dates by which manufacturers of each of the three categories of asbestos-
 containing products must provide labels, cease production, and end distribution.  It also
 provided that exemptions may be granted by the EPA only in very limited circumstances.

 CONSUMER PRODUCT SAFETY COMMISSION

 Proper sampling and assessment of waDboard and joint compound has been a topic of
 interest in the asbestos abatement industry.  There is insufficient research concerning the
 types and concentration of asbestos in such  materials.  EPA has cited some firms for not
 sampling these materials during AH ERA inspections.  For these reasons, it is Important to
 review a ban of asbestos  in joint patching compound by the Consumer Product Safety
 Commission (CPSC).

 The CPSC  banned  "consumer patching compounds containing  intentionally  added
 asbestos" with regulations  published in 16 CFR 1304 in December 1977. The regulation
 defines consumer patching compounds as "those  that are customarily  produced or
 distributed for sale to or for the personal use, consumption or enjoyment of consumers in or
 around  a permanent or temporary household or residence, a school, in recreation, or
 otherwise." The ban  on manufacturing took  effect January 16, 1978, and the ban on all
 affected products took effect June 11, 1978.

 Merely labeling products for industrial use only would not exdude them from the ban, so
the CPSC wrote a broad  definition tor consumer patching compound.  However, the
definition  of  "intentionally-added asbestos"  did  have an exception-"Whenever  a
manufacturer finds out that the finished product contains asbestos, the manufacturer win be

manufacturer takes steps to reduce the asbestos to the maximum extent feastole."  The
nature and extent of the steps were not in the rule.

Whatever the reason, joint compounds which contain over one percent asbestos have
been found in building construction completed nearly ten years after the ban took effect
This issue, along with future industry and regulatory decisions, is important to consider in
evaluating survey results.

OSHA REGULATIONS

OS HA has the  legislated obligation to issue  and enforce regulations which protect the
safety and health of workers.  This is  done  by setting minimum standards with which
employers must comply. Project designers need to design projects so that there can be fun
compliance with OSHA regulations. However, merely meeting OSHA regulations will not
be adequate for protecting workers in some  cases.  OSHA has acknowledged that
some risk remains for workers at the current PEL Thus, the project designer may
choose to write  and enforce more stringent specifications in order to protect workers from
safety and health hazards and to protect the building owner and project designer from
legal liabilities.

The official enforcement of OSHA standards  for a project will be performed by either a
federal or state OSHA office and its enforcement officers.  About half of the states and
territories have OSHA programs and  the other half have federal  OSHA programs.
California. Indiana, North Carolina, and Iowa are examples of states with OSHA programs.
Missouri, New Jersey, Georgia, and Mississippi are examples of states with federal OSHA

 programs. Federal and state OSHA regulations and enforcement are usually similar, but
 often not identical State regulations are not permitted to be less stringent than the federal
 regulations.  Regulatory interpretation and enforcement emphasis may vary some from
 state to state, and from inspector to inspector, in both state and federal enforcement states.

 Both the state program states and the federal program states have similar regulations with
 which the project designer should be familiar. These federal regulations include:
       •  29 CFR 1926.58 Asbestos Standard
       •  29 CFR 1926.59 Hazard Communication Standard
       •  29 CFR 1910.134 Respiratory Protection Standard
       •  29 CFR 1926 General Safety and Health Requirements

 A summary of these OSHA standards follows.  However, project designers  should also
 obtain, study and follow the complete OSHA  standards as they appear in the Code of
 Federal Regulations (CFR).  It should also be  noted that the OSHA standard is currently
 under revision.

 29 CFR 1926.59 Construction Asbestos Standard

 SCOPS and Application -OSHA  has two specific  asbestos standards-1926.58 and
 1910.1001.  The 1926 standard is intended for all asbestos control  activities (including
operations and maintenance) since  they  are  judged by OSHA to be construction and
maintenance actions regardless of the type facility in which they are performed.  The
1910.1001  is  a general industry standard  for  those companies  still manufacturing
asbestos-containing products such  as brake shoes and pads.

Alf Limits - There are currently three limits for asbestos filers in air. The lowest air limit is
the action level (AL) of 0.1 fibers per cubic centimeter (f/cc) measured over an eight-hour
time-weighted average (TWA).  Exceeding the AL only requires the employer to:  continue
air monitoring, offer initial and  annual asbestos training, offer an asbestos medical exam
after 30 days of exposure above the AL during a calendar year, and keep certain records.

The other two air limits are a permissible exposure limit (PEL)  of 0.2 f/cc as an eight-hour
TWA  and an excursion limit (EL) of 1.0 f/cc measured over the 30 minutes of maximum
exposure for each employee monitored.  If either the PEL or EL limits are exceeded,  then
the following are added to AL requirements: appropriate respirators and clothing must be
furnished and used as listed  in the standard; a regulated  area must be established.

regulated area; "Danger" signs  (red. black and white in color with OSHA-required wording)
must  be posted at all possbie  entrances into the regulated area; other employees in the
area must be informed of the regulated area and its significance; any feasible engineering
and work practice  controls must be implemented to reduce  airborne fiber levels; a
decontamination area consisting of a dirty equipment room, shower area, clean room, and
storage facilities must be established for employees, equipment and supplies entering and
exiting the regulated area; and multiple records must be kept

At the time of publication of this manual, OSHA is proposing new exposure limits.

Communication Among Employers -  This allows the other employers to train their
employees in the proper actions around the regulated area.  It also informs the other

 into their hazard communication program as appropriate.
 Regulated Areas - These are required when either the PEL or EL are exceeded.  Activities
 in these areas must be supervised by an OSHA-defined  asbestos 'competent person."
 Asbestos 'Danger signs with required wording must be posted at all possible entrances.
 The area must be contained and placed under negative pressure, if feasible; acceptable
 respirators and clothing must be worn in the area; smoking, drinking, chewing gum, using
 makeup, and eating must be prohibited in the area; all feasible engineering controls and
 work practices must be used to reduce airborne fiber levels; and a decontamination setup
 must be established.

 Exposure Monitoring - Regardless of whether  workers are  wearing  respirators,
 representative air samples must be collected and analyzed according to Appendix B of the
 standard lor an employees who might be exposed above one of the three air limits (AL,
 PEL, and EL).  According to the  OSHA Field Operations  Manual (FOM), at least seven
 hours of sampling must be performed on each employee being checked for the eight-hour
 limits.  Additionally, if there is any possibility of the EL being exceeded for an employee, a
 short-term sample (30-45 minutes) must be collected on  that employee during his/her peak
 exposure  for comparison to the 30-minute  EL.  The OSHA FOM allows as few as 25
 percent of the workers in  each work category to be monitored.  However, the employees
with the expected highest exposures should be included in the  25 percent monitored.
Appendix B requires the samples to  be  read by a person having passed the NKDSH 582
course or equivalent.   OSHA compliance air samples  must be analyzed with  a phase
contrast microscope.  Then, once the air monitoring results are received, they  must be
posted or given in writing to al affected employees as soon as possible.

 being taken out of the regulated areas must be transported in sealed impermeable
 containers and  must  be appropriately labeled.   Laundries that are sent contaminated
 dothing must be notified.

 Hygiene Facilities and Practices  - When employees are exposed above the  PEL or EL,
 the employer must establish a decontamination area for the employees.  It must be
 adjacent and connected to  the regulated area. The decontamination area must at least
 include a dean room,  shower area, and dirty equipment  room, in that order, leading from
 the outside to the project area.  The dean room must have lockers or other  appropriate
 storage containers  for each  employee's  street dothing.   The shower must indude a
 combination of hot and cold water in accordance with the referenced 29 CFR 1910.141
 standard. The dirty equipment room must be outfitted with impermeable, labeled bags or
 containers for disposing or containing asbestos-contaminated dothing and supplies. The
 asbestos competent person for the regulated area must ensure that employees enter and
 exit the regulated area by correctly using the decontamination area. Even at exposures
 below the AL, the employer must ensure that employees do not smoke in work  areas
where they are occupationaJty exposed  to asbestos because of  activities in the work area.
Communication nf jJazards to Employees — The employer must train all employees who
are exposed to airborne fiber concentrations above the AL.  Those employees must be
trained at the time of initial assignment and at least yearly thereafter.  No specific duration

Housekeeping - Al vacuuming equipment used must have HEPA filters.  Asbestos waste,
scrap,  debris,  bags, containers, equipment, and asbestos-contaminated clothing
consigned for disposal must be collected and disposed in sealed and impermeable bags
or containers which are properly labeled.

Medical Surveillance - The employer must provide a medical surveillance program for all
employees prior to their wearing respirators or if they are exposed above the Al or EL for
more than 30 days per year. The exams must be by or under the supervision of a loensed
physician and must be provided at reasonable time  and place without cost to the

 29 CFR 1926 General Safety and Health Recuirements
OSHA has specific and applicable construction standards for a variety of other safety and
health considerations which must be complied with, including:  scaffolds, walking/working
surfaces, ladders, electrical, lockout/tagout, and confined space entry. Many of these are
covered in the section on Safety Considerations.
                       LIMITATIONS OF OSHA STANDARDS
     The OSHA  standards, like  most government standards,  are  intended  to
     establish minimum levels of protection for the employees.  For asbestos, OSHA
     has acknowledged that its standard does leave significant risk to workers.  In
     some cases, the project designer may consider writing specifications which are
     more stringent than  the OSHA standards. Good examples of candidates for
     tighter job specifications are: requiring employees to wear respirators and
     protective clothing at trigger levels lower than or other than the PEL and EL;
     using respirators which protect to a level lower than the OSHA allowed level of
     0.2 f/cc inside the  respirator; and  requiring guard rails on all scaffolds
     regardless of the height
•DEPARTMENT OF TRANSPORTATION (DOT) REGULATIONS'

The  U.S Department of Transportation (DOT) administers  the  regulations for the
transportation of hazardous materials which are found in CFR Title 49. Parts 171 through

hazardous materials, including asbestos, in commerce. The main requirements covered in
theHMRare:
       •  Classifications of Materials
       •  Packaging
       •  Shipping
       •  Hazard Communication

All of these requirements are relevant to the design of asbestos projects.  Recent changes
to the regulations require that both the past and current law as H pertains to abatement
design be reviewed in this section.  It Is  Important for the reader to note that the
newly revised regulations are  still undergoing  Interpretation.  With time, It Is
likely  that  the practical  Implementation of these  regulations with  respect to
asbestos-containing materials will become more clear.  The discussion provided
here is meant to point out some  of the more significant changes and when they are
projected to come into effect The reader will need to seek additional clarification on exact
requirements for labeling, placarding, etc. as these requirements become effective.

On  October 1, 1991. regulations that significantly revised the HMR took effect.  These
revisions were published in the Federal Register on December 21, 1990, as 49 CFR Part
107, et a!..  Performance-Oriented Packaging  Standards;  Changes of Classification,
Hazard Communication. Packaging and Handling Requirements Based on UN Standards
and Agency  Initiative; Final Rule. Depending on interpretation, the new regulations may
significantly  change the classification, packaging, shipping and hazard communication
requirements for asbestos.

 Since the regulations became effective, the DOT has issued revisions to the HMR and has
 indicated that more are likely. A recent significant revision was published in the Federal
 Register on October 1, 1992.  Written requests  to the DOT for clarification of specific
 asbestos issues in the HMR have also been made, but no official responses have been
 noted as of this writing. Further, the effective dates for many of the requirements are
 phased over the next few years which has deferred the impact of the rule. The previous
 DOT asbestos regulations took more than a year of interpretations and revisions before
 they were officially interpreted by the DOT and adopted by the asbestos abatement
 industry.

 This section will first review the previous DOT asbestos regulations. This will be followed
 by a review of the significant changes to asbestos regulations in the revised  HMR.

 Previous DOT Regulations

 The last substantive change  to the HMR for asbestos was published in  1986.  These
 regulations were later revised and full adherence  to the requirements were delayed  until
 January 1, 1988.  Those regulations  listed  friable asbestos as  a  Class 9 hazardous
 substance with a reportabte quantity (RQ) of one pound. Two shipping descriptions in the
 hazardous materials table (HMT) applied to asbestos:
      •  Asbestos. ORM-C
      •  Hazardous substance, solid, n.o.s., ORM-E

The  Asbestos, ORM-C  classification was referred to  as 'commercial value asbestos*
because  of exceptions found in  173.1090 of the HMR which excluded "manufactured
products—whose commercial  value is not dependent on their asbestos content.' DOT

                                        Socbon XII - Ftdofal. Stata and loot ftogutattry Raqubomonts
designed this classification for refined asbestos which was used to make products and not
for asbestos-containing products or asbestos abatement waste.

For regulation of asbestos debris and waste from abatement projects, DOT directed the
industry to use the Hazardous Substance, Solid, N.O.S. (not otherwise specified), ORM-E
classification.  The identification number for  this classification was  NA9188.   This
classification  required that any  single container  (bags or drums) of material which
exceeded the RQ (one pound) be labeled and transported in closed trucks or dumpsters.

Revised Regulations

Material Classification -The most obvious revision to the HMR is the proper shipping
names that are found in the HMT. In the December 1990 Final Rule, DOT eliminated the
former classifications and listed two new descriptions:
       •  Blue asbestos (croddolite) or Brown asbestos (amosite,  mysorite)
       •  White asbestos (chrysotjle, actJnolite, anthophytlite, tremolite)

On October 1,1992. DOT published a revision of the Final Rule which designated the  Blue
or Brown asbestos  and White asbestos shipping names for international use and created a
new generic Asbestos shipping name for domestic transportation of aH forms of asbestos in
the United States.  The  identification number for domestic Asbestos is NA2212.  The
following  review will  concentrate  on the  requirements of the  domestic Asbestos
classification.  Al forms of asbestos  are Class 9 hazardous materials.  The RQ for friable
asbestos remains one pound.

 As with  the previous HMR, there are exceptions to the rules.   Nonfrlable asbestos
 continues to be excepted and is not subject to the requirements of the HMR. The HMT also
 lists a nonbulk quantity packaging exception in 173.216.  While the issue of 'commercial
 value" was dropped, this exception does exclude. "Asbestos which is immersed or fixed in
 a natural or artificial binder material (such as cement plastic, asphalt, resins or mineral
 ore), and manufactured products containing asbestos....' ft would seem that manufactured
 products containing asbestos which are friable would not be excepted from  the nonbulk
 quantity packaging requirements.

 Exceptions notwithstanding, the revised HMR includes a series of new requirements and
 restrictions.  The following paragraphs will review the packaging, shipping  and hazard
 communication requirements which  pertain to the design of asbestos abatement projects.

 Packaging Requirements - One  of the major goals of the new HMR was to  update  and
 improve  the packaging requirements.  DOT discarded the previous practice of directly
 specifying the packaging for  each material  type and instead instituted two new concepts:
 packing groups and performance-oriented  packaging standards (POPS). Each material
 classification is assigned to packing  groups I. II or III  based  on the  level of hazard
 associated with transporting  the material.  Packing group I is the most  restrictive, while
 packing group III is the least restrictive.  Asbestos is in packing group III.

There are extensive "performance" guidelines for packing group III POPS in the HMR, but
these do not appear to apply to  asbestos  because of two packaging exceptions in the
 HMT, which are based on the weight of material in each container. Remember, nonfriabie
asbestos and friable asbestos less than the RO are already excluded  from regulation
under the HMR.

STUDENT MANUAL                                        AS86STOS ABATEMENT PROJECT DESIGN
                                         Section XII - Federal. State and local Ftegutoiory Roquromonts
The first packaging exception found in  173.4 is for small quantities of Class 9 (asbestos)
materials.  This exception stales a small quantity of material is excepted from other
packaging  requirements (i.e., packing group) If it meets certain specified POPS criteria.
First, there must be no more than one ounce of material per container and the entire
package must not exceed 29 kg (64 pounds). While this will not apply to bags of asbestos
waste from abatement projects, it could apply  to the shipment of bulk samples collected
prior to designing a project.  Second, each container must be constructed of plastic,
earthenware, glass, or metal wtth a minimum thickness of 0.2 mm (0.008 inch). Sample
container lids must be held  in place  with wire, tape, or other positive means.  Each
container must be secured inside the package with cushioning.  Finally, once samples are
contained,  specified package testing requirements  must be certified to have been met
before shipment

The second exception to packaging regulations appfies to friable asbestos waste before it
is transported by a waste hauler. The weight of the material in each container is again the
determining factor.  Because each container  of asbestos waste will exceed the small
quantities exception in 173.4, it is instead subject to the exception for nonbuik quantities as
found in the already referenced 173.216.  Nonbuik  quantities are defined as a RQ less
than 30 kg  (66 pounds). According to this exception, friable ACM must be transported in
rigid, leak-tight packaging such as fiber drums or hopper-type motor vehicles. Bags of
asbestos material must be dust and sift proof.

There are other noteworthy packaging issues in the HMR which could apply to an asbestos
abatement  project  One issue is the packaging requirements for mixtures of hazardous
materials.  Assume that during the abatement project, a contractor removes both asbestos-

 containing floor tile and mastic. A liquid mastic remover is used to remove the mastic.  The
 mastic remover is classified as a hazardous material According to the HMR, if more  than
 one hazardous material is combined, then the total material is classified according to the
 highest applicable hazard class. Therefore, if mastic remover is combined with asbestos,
 then the classification could be different and a whole new set of regulations for the higher
 class of hazard would have to be followed.

 During the course of the abatement project, a contractor may want to reuse some of his
 fiber drums.  This packaging will have  to be inspected to ensure that it continues to
 conform with the  requirements of the rule prior to reuse.  In addition, it may not be  reused
 unless it is free from incompatible  residue, rupture, or other damage which reduces its
 structural integrity. The new HMR also states that plastic packaging (plastic bags) may not
 be reused at all.

 Shipping - After the samples or asbestos  waste are packaged, the shipper must select an
 appropriate carrier.  Just as the packaging regulations vary depending on the weight of
 material, the regulations for shipping differ depending upon the material classification.   Up
 to 200 kg of asbestos can be sent on board passenger or cargo aircraft or rail car.

 It  is the shipper's responstoHity to determine  what materials are being shipped, prior to
 shipment. This is not possible In the case of bulk sample shipment because the samples
 are being shipped in order to determine what the asbestos content is. Without  any
 knowledge of what the samples do or don't contain, the "worst case" must be assumed. In
other words, if the shipper thinks that there is  asbestos in the samples, then the shipper
must assume that asbestos is In the  samples.  The asbestos content assumed to be in the
samples should be based upon past experience and professional judgment.

Hazard Communication  Requirements - Prior to abatement the designer wiB need to
incorporate the new HMR into the project specifications for enforcement during the project
An updating of specifications to incorporate  the  new  hazard communications  and
transportation requirements will be in order.   It should be noted that while the HMR is
effective October 1, 1991, compliance with the hazard communication requirement for
Class 9 materials is not mandatory unti October 1, 1993.

The revised  HMR Includes changes to the shipping papers,  marking, packaging,  and
transportation requirements.  There is a transition  period for complying with  the new
shipping paper and label requirements.  On preprinted labels  and shipping papers, the
HMR requirements must  be  complied with no later than October 1, 1992.  It should be
noted that there  are exceptions to the marking and labeling requirements for limited
quantity (less than 66 pounds) shipments.

The HMR states  that it is unlawful to tamper with any of the required markings or to
misrepresent the material being transported.  Strictly speaking, only asbestos, asbestos-
containing  materials, or asbestos-contaminated materials can be put into prelabeled,
premarked bags.  Storage of other items, such as decontaminated respirators, extension
cords and towels in these bags will be unlawful.

The shipper is still required to prepare shipping papers for the asbestos being transported.
As required by current regulations, the shipping description, name of the shipper, and an
emergency response telephone number wHI continue to be required.   The revised HMR
requires that the shipping description now include the  proper shipping name, hazard class,
identification number, packing group, and total quantity of material.  Furthermore, "RQ"

 must be included at the beginning of the shipping description. The certifications that have
 been required by current regulations on shipping papers have not been changed and must
 still be included.

 The shipper must mark packages greater than 66 pounds that contain asbestos. One
 change In the HMR is that packages are to be marked with the consignee's or consignor's
 name and address except when the material is transported by highway only and wil not be
 transported from one motor carrier to another.  In addition, the new HMR requires that
 packages must now be marked with the proper shipping name  and identification number
 for the material contained in it  Material that is authorized for transportation must have the
 proper label with new specifications for the colors, design, durability, location, and printing
 acceptable for the labels.

 In addition, bags of asbestos material that are transported in closed motor vehicles are to
 be loaded by and tor the exclusive use of the consignor and unloaded by the consignee."
 This means that a contractor who removed the asbestos must load it onto the vehicle and
 that the person who transports the material must unload it

 If nonfriabte asbestos is the only waste being transported, the shipment is not subject to the
 requirements of the  HMR. This would include materials such as Transite, floor tile, resitent
sheet flooring, and roofing materials. These materials are those classified in the NESHAP
regulation as Category I and II nonfriabte materials. According to the NESHAP regulation,
these asbestos-containing materials could possibly be left in place during the demolition of
the building.  Therefore, it appears that  this final rule parallels the revised NESHAP
regulation and that construction debris will not be regulated under the new regulation even
though this debris could contain asbestos.

STATE AND LOCAL REGULATIONS
States, counties, cities and localities are often permitted and choose to have and enforce
standards different from the federal standards and from each  other's standards.  For
example, state standards can usually be different from federal standards as long as they
are at least "as effective as' the federal standards.

The following are some of the areas for which states, counties, cities, and localities choose
to have and enforce standards different from the federal standards:  certifications  and
licenses for  contractors, consultants, inspectors, air monitoring specialists and project
designers; NESHAP trigger limits and notification periods; project notifications and fees;
and not automatically accepting people certified in other states.  Examples of differing state
and local requirements at the time of writing include:  not being able to enter an abatement
area  in New York City unless you have their "Limited Waste Handlers"  license;  being
required to have a Florida asbestos contractor's or consultant's license to direct work there;
and being required to be a licensed state asbestos abatement contractor or licensed state
asbestos roofing abatement contractor to perform work on asbestos-containing roofs in
Georgia.  Many other states and cities have  their own versions of differing regulations or
interpretations. Furthermore, those regulations and interpretations are subject to additions
and updates.

Thus, all project designers, consultants, and  contractors need to learn the state and local
regulations of the area in which the project is being planned.  Then they must comply with
the most stringent of all the applicable regulations while the project Is being performed.

Learning Objectives:
      1.    Divide into workgroups.
      2.    Understand hypothetical design problem: "AHERA School".

Study Questions:
      1.    What are the benefits of using an interdisciplinary approach to asbestos
            abatement?
      2.    What is the role of the designer in regard to the management plan?
      3.    Why  should asbestos abatement  projects be designed, not left to a
            contractor to select the best method?

                                        MANAGEMENT PLAN


Ab  t m nt Alternatives

1.    REMOVAL

     Advantages:

     a.    Eliminates asbestos source

     b.    Eliminates need for special operations and maintenance
          program

     c.    Eliminates potential for future fiber release


     Disadvantages:

     a.    Replacement with substitute material may be necessary

     b.    Porous surfaces may also require encapsulation

     c.    Improper removal may raise fiber levels in air

     d.    Generally the most expensive


2.    ENCAPSULATION

     Advantages:

     a.    Reduces asbestos fiber release from material

     b.    Does not require replacement of material

     c.    Initial cost may be lower than removal

-------
     Disadvantages:

     a.   Asbestos source remains and must be removed later

     b.   If material is not in good condition, sealant may cause material
          to delaminate

     c.   Periodic reinspection required to check for damage or
          deterioration

     d.   Encapsulated surface is difficult to remove and may require
          costly techniques for eventual removal

     e.   Further fiber release is possible if encapsulant is damaged


3.    ENCLOSURE

     Advantages:

     a.   Reduces exposure outside the enclosure

     b.   Initial costs are lower than removal

     c.   Usually does not require replacement of material


     Disadvantages:

     a.   Asbestos source remains and must be removed later

     b.   Fiber release continues behind the enclosure

     c.   Fibers released during construction of enclosure

     d.   Long-term cost could be higher than removal

            useful?
      3.    Under what conditions should you separate the abatement contract from
            the  replacement  contract?  When would rt be  appropriate to include
            abatement and replacement in the same contract?
      4.    What are some considerations that must be addressed when separating
            abatement from replacement?
      5.    What is the purpose of drawings?  What role do drawings play in the total
            design presentation?

Second Edition
Asbestos Abatement & Management in Buildings
Model Guide Specifications
              ABSTRACT
                           Mational Institute of
                           BUILDING SCIENCES

-------
In 1986 the National Institute of Building Sciences (NIBS) first published the document. Asbestos Abate-
ment and Management in Buildings, Model Guide Specifications, as a resource for persons interested in
asbestos abatement in buildings.  In 1988 NIBS rcpuhlishcd the Model Guide The 1988 edition contains
numerous re\ iiions ami several new sections which enahle users to deal with the requirements of A HERA
and to benefit from advancing technology and procedures developed ov er the past two years. This guide
was developed in response to a national nee;! for authoritative advice and guidance in the design and
execution of abatement of asbestos-containing building materials (ACM) in the following four categories of
activity:

       ':) maintenance and  repair      2) encapsulation       3)enclosure   4) removal

A number of user groups are expected to benefit from the direct use of this information. Of'primary-
interest to design professionals (architects, engineers, and cm ironmcntal consultants), building owners, and
abatement contractors, this document provides an outline of important information on specifying asbestos
abatement and main'criance and repair of ACM in buildings Regulatory agencies may also find valuable
information in the Model Guide Specifications. It is expected lhat, o\ er time, a more consistent approach
to asbestos abatement pro: eels ".ill evolve through the proper use of thi.i guidance material

As a consensus document, the Model Guide Specifications rctlcct the concerns, viewpoints, and agree-
ment of the more than eighty-five members of the Institute s Asbestos I ask Force who contributed their
time, know ledge, and effort to define up-to-date model procedures that may be used to achieve quality and
consistency in asbestos abatement work. Refinements to materials prepared b> the Institute's contractor
were made through a series of highly technical review sessions and written correspondence. Finally, the
document was accepted by written ballot by the Task Force. The following concepts and content are
incorporated in the Model Guide Specifications:

A.  Basic Asbestos Abatement Design Principles include: 1) isolation of airborne contamination, 2)
    isolation of wa:crbome contamination; ?) protection of room surfaces; 4) worker protection; 5)
   regulations and standards; 6) testing; 7) wet removal; 8) disposal; 9) encapsulation; and 10)
   enclosure.

    I.  Isolation of Airborne Contamination: During asbestos abatement operations that disturb ACM.
       the work area will be contaminated by airborne asbestos fibers. The balance of the building
       must be protected from this contamination. This is accomplished by sealing all points of
       entrance to the work area, and maintaining the work area at an air pressure lower than that of
       surrounding areas (above and below as well as adjacent to)

   2.  Isolation of Water Borne Contamination: Water with a wetting agent added (amended water)
       are normally used to wet asbestos containing materials before removal. Non-asbestos materi-
       als, including baps and drums being removed from the work area for disposal are decontami-
       nated by washing. Work areas are misted with amended water to reduce air borne fiber  levels,
       and workers shower when leaving the work area. 'I his extensive use of water on an asbestos
       abatement project results in considerable possibility for contamination of the building outside
       the work area by contaminated water. Where a removal encapsulant is used for wetting  of
       materials the situation will be somewhat ameliorated. However, ever, in  this instance there  is
       typically considerable water used on an abatement project with the atlendanl concern with
       water borne contamination.

-------
 3   Protection of Room Surfaces: Asbestos abatement projects, particularly removal projects.
    develop a considerable amount of contamination inside the work area. This contamination can
    be in the form of air bomc fibers, dusu debris, wet slurry or a combination of these forms of
    contamination.  Accordingly, the surfaces of the room need to be protected from this contami-
    nation.

 4.  Worker Protection: Protection of the worker is the responsibility of his employer, the Contrac-
    tor. Great care must be used in writing a specification to avoid transferring this responsibility
    to the Owner. Building Owners conducting asbestos abatement in their buildings with their
    own employees  assume similar responsibilities for their workers.

 5.  Regulations and Standards.  Applicable regulations and standards should be made a pan of the
    specifications for the work to assure the contractor is responsible to comply w ith their adminis-
    trative, technical, and other pro\ isions. Further, regulations emanating from the federal, state,
    and local governments having jurisdiction change rapidly. Many state and federal regulations
    are identified in  the NIBS guide, however, the designer is responsible to research the extent
    and impact of such laws and  regulations, especially at the state and local levels of government.

6.  Testing: Ty pically, both the  Owner and C'ontractor conduct air mon::oring during an abatement
    project:

    a.  Owners often sample and analy/c the air inside and outside the work area throughout the
       work to insure that the building outside the work area remains uncontaminated. This
       sampling will normally be carried out in a different manner than and have nothing to do
       with the air sampling required by OSHA forthe Contractor's respiratory protection plan.

    b.  Contractors  are required by OSHA to sample the air in the breathing zone of his workers to
       demonstrate the adequacy of respiratory protection provided for workers

7.   Wet removal: The asbestos-containing building material to be removed is saturated with
    amended water or a removal encapsulant and hand scraped from its substrate.

8.   Disposal: Material which has been removed must be taken out of the work area through an
    equipment decontamination unit which is different from the personnel decontamination unit.
    This material is then land filled in accordance w ;ih HPA KESHAP regulations

9.   hncapsulation: Encapsulation involves either binding the constituents of an asbestos-containing
    material together and to their substrate (penetrating encapsulant), or coating it with a tough
    flexible or hard coatine (bridging encapsulant)  This process is intended to greatly restrict or
    prevent fiber release

10.  HncInsure: Knclosing an asbestos-containing installation can be accomplished by sealing it
    behind a permanently constructed barrier.  This barrier could be constructed of gypsum dry-
    wall, tongue and groove plywood, concrete, masonry, metal or ether materials  The construc-
    tion is made as airtight as possible.  The use of enclosure is most appropriate  if there is no need
    to obtain access into the enclosed area. I hese Guide Specifications provide guidance on the
    use of gypsurn dry wall systems for such an enclosure; although other systems such as wood.
    concrete, concrete, and masonrv can be used.

B.  lnlroduilkLQ.aPiUjlStOtQ.ii.ons forJL;se: A comprehensive new 80 page section of the guide contains
    information to help practitioners utilize the Guide Specifications effectively and efficiently. The
    section:

    1.   Explains asbestos abatement and management in the context of the content and organization of
        contract documents and the roles and relationships of the participants in the process with
        emphasis on the owner, designer, and contractor.

    2.  Outlines and explains the design of an asbestos abatement project—the decisions that must be
        made and the rationale for making those decisions.

    3.  Describes the basic elements of the construction and operation of buildings, insofar as it affects
        the abatement of certain asbestos containing building materials.

    4.  Describes how to assemble and contract with a qualified design team

    5.  Explains how to develop, organize, and coordinate contract documents, and what each should
        contain.

    6.  Describes how to develop and coordinate a bidding package, including where to obtain and
        how to use standard forms.

    7.  Includes helpful hints on how to pre-qualify contractors for negotiated and bid contracts—what
        information to ask for and how to evaluate it.

    8.  Provides helpful procedures for negotiating and bidding contracts.

    9.  Outlines and explains how to administer contracts from receipt of bids to project close out.

    10.  Includes a brief abstract of each section in the guide specifications.

C.  Contract Documents:  In order to organize the information conveyed to the contractor hired to
    perform construction work by contract, the construction industry has developed a system to catego-
    rize the various types of responsibilities of both the contractor and the owner. The parts of this
    system, known as contract documents, are:

                     Owner Contractor Agreement
                     General Conditions (of the Contract for Construction)
                     Supplementary and Other Conditions
                     Technical Specifications
                     Contract Drawings
                     Addenda (changes made before bids are received)
                     Modifications (changes made after award of the contract)

    The NIBS Model Guide Specifications are intended to assist designers in the development of the
    technical specifications needed for asbestos abatement and management work. Information in the
    introduction to the NIBS document also provide gu:dancc on how to coordinate the  specifications
    with the other pans of the contract.

D   NIBS' Model Guide Specifications: The Model Guide Specification. Asbestos Abatement and
    Management in Buildings is a compilation of thirty-four guide specification sections which can
    Se used a-; a manual to assemble technical project .specification sections for:

                      - Removal of Asbestos-Containing Materials
                      - Hncapsulation of Asbestos-Containing Materials
                      - Enclosure of Asbestos-Containing Materials

    In addition, the Model Cmidc Specifications can be used ;o prepare the specifications necessary to
    define the maintenance and repair portions of an asbestos management and control program which
    arc appropriate for an outside contractor to cam* out. These sections arc identified in the Guide.
    SpiaJOiations under Maintenance of Asbestos-Containing Materials. Also, requirements can be
    developed through use of this document for conduct of these types of work by the building owner's
    forces as well.

    1.   Format: Sections in the Model Guide Specifications are arranged according to the Construc-
       tion Specification Institute's "Mastcrformat" which has become the standard for presentation of
       specification material in the construction industry. "Masterformat" organizes specification
       material into sixteen divisions which correspond to related construction activities Sections
       further break down the work of each division to correspond to the work accomplished by
       common trades, thus facilitating organization of the work into subcontracts.

       Most asbestos abatement activities arc defined in Division  1. General Requirements, which
      contains temporary facilities, quality control testing, and administrative requirements. Specifi-
      cation sections for remov al operations are described in Division 2. Site Work, as specialized
      demolition work Sections on encapsulation o;"asbeslos-conta:ning architectural finishes and
      gypsum drywall enclosure systems are included in Division 9, Finishes, as they constitute
      specialized interior finish work. Repair and encapsulation of pipe insulation and lagging arc
      located in Division 15, Mechanical.

   2.  Section Organization: The Model Guide Specifications organize each section into the Con-
      struction Specifications Institute (CSI) three part format. This format includes:

      a.  Part I (icncral: includes such information as a description of the work in that section.
          identification of related contract documents, required submittals, inter-sectional coordina-
          tion (related work specified elsewhere), and identification of referenced standards.

      b.  Part 2 Products (products, equipment, or materials): specifies items physically provided by
          the contractor through the use of specific prescriptive or performance provisions or through
          reference to standards or other criteria

      c.  Part 3 Kxcculion: defines requirements to be followed b\. the Contractor in actually earn-
          ing out the work, including sequencing of the work with requirements of other sections and
          special requirements for methods which can be described or incorporated by reference to
          installation standards.

-------
    3.  Compatibility with "MASTKRSPE-X"'*": To facilitate coordination of the Model Guide Speci-
       fications with other building renovation needs, its format is compatible with
       "MASTKRSPKC." '• a subscription guide specification service published by the American
       Institute of Architects (AIA).  'MASTERSPEC" is a series of specification sections written in
       a uniform format which can be used to develop a project specification by selecting and editing
       the appropriate sections from over 130 sections available. Because this service is wideh used
       by architects and engineers, the Model Guide Specifications have been made compatible with
       "MASTKRSPF.C," so they can readily be used to develop consistent and coordinated specifica-
       tions for related work such as reinsulation or re-fireproofing. Also, they are more easily
       coordinated with the standard contract document forms published by the AIA and the Engi-
       neers Joint Contract Documents Committee (EJCDC).

       The (iuide Specifications can also be used with other commcrciall) available guide specifica-
       tions systems such as "SPECTEXT""" published by CSI. or with guide specifications devel-
       oped and maintained by government agencies and required to be used for their projects.

    4.  Advisory Notes: In the text of the technical sections of the Model Guide Specification notes
       are included to provide additional guidance to the user. These notes must be deleted after
       preparing the project specifications. The following is an example of the format and style of the
       no:cs:

E.  Using :he Model  Guide Specifications: In writing project specifications, the Asbestos Abatement
    ami Management in Buildings, Model Guide Specifications is used by selecting the sections
    appropriate for the project and editing each to meet the project's needs. Some sections are neces-
    sary for any type  of abatement project.  Other sections contain specific requirements and will be
    appropriate only  for certain types of abatement work. The appropriate sections are selected from
    the "Master Table of Contents" to form the basis for the specifications for removal, encapsulation,
    enclosure, or maintenance and repair

The second edition of MBS* ASBESTOS
ABATEMENT AND MANAGEMENT IN
BUILDINGS; MODEL GUIDE SPECIFICA-
TIONS continues to be one of the most widely
used technical documents on abatement and
maintenance and repair of asbestos-containing
materials in buildings. It is an essential tool
for design professionals, contractors, and
building owners. In addition, it is rccogni/ed
as an effective tool for organizations providing
training in asbestos abatement and manage-
ment procedures.

In 1988. NIBS updated the GUIDE SPECIFI-
CATIONS to include requirements resulting
from new federal regulations and provisions
for new products, equipment and procedures.
and refinements in existing practices for asbes-
tos abatement, maintenance and repair. In
1991. NIBS developed two new sections on
removal of non-friable asbestos-containing
flooring materials and a new "Introduction and
Instructions for Use" to facilitate more effec-
tive use of the GUIDE SPECIFICATIONS.

Regulations and standards promulgated by the
Environmental Protection Agency (EPA) and
the Occupational Safety and Health
Administration (OSHA) set responsi
bilities  for building owners, contrac-
tors, designers, and others involved
in the asbestos work.  The GUIDE
SPECIFICATIONS Is coordinated
with relevant provisions from
AHERA. NESHAP. and the OSHA
Construction Rule for abatement
contracts between owners and
abatement contractors.
NIBS had distributed more than 5000
copies of the MODEL GUIDE SPECIFI-
CATIONS since it was first published in 1986.
The 550 pages in the current edition include
provisions for new products, equipment and
procedures, and refinements in existing prac-
tices for asbestos abatement and maintenance
and repair.  More than 100 leading technical

NIBS1 GUIDANCE MANUAL: ASBESTOS
OPERATIONS AND MAINTENANCE WORK
PRACTICES is a technical procedures manual
which provides detailed guidance to owners,
asbestos program managers, and to asbestos
operations and maintenance (O&M) workers for
managing asbestos-containing materials (ACM) in
buildings. NIBS developed this document in
 cooperation with the Environmental Protection
    Agency (EPA) and the General Services
      Administration (GSA).
         The O&M MANUAL addresses three
         different types of ACM found in
          buildings:

          •Surfacing ACM which are sprayed
         or troweled on ceilings, walls, and
         structural members.
       Thermal System Insulation (TSI) which
     can be found around pipes, ducts, boilers,
  and tanks.

•Miscellaneous ACM such as ceiling and floor
tile, roofing felts and shingles, and wall board

In order to present a full range of information, the
O&M MANUAL provides guidance on the design and
validation of O&M programs, checklists for asbestos
program managers and O&M workers, detailed
descriptions of 26 general O&M procedures and 57
specific work practice activities. It lists tools and
equipment, special procedures applicable to each
work practice, the appropriate number of workers to
carry out each task, and the responsibilities of each
worker. The O&M MANUAL addresses three differ-
ent levels of precaution which may be warranted by
specific building conditions.

The value  of this O&M MANUAL is in its presenta-
tion of a range of guidance for common operations
and maintenance procedures, which enables owners to
efficiently meet applicable regulations and the desired
levels of protection in varying building conditions.

One hundred and  eighty of the nation's leading
experts in building construction and asbestos abate-
ment issues gave their advice and guidance in the
development of this 350-page consensus document

activity before proceeding to the next.


GENERAL;

Work Area:   the  location where asbestos-abatement  work occurs.
It is  a  variable of the extent of work of  the  Contract.   It may
be a portion of  a room,  a single  room,  or a complex of rooms.  A
"Work Area" is considered contaminated  during the work,  and nust
be isolated from  the  balance  of the  building,  and decontaminated
at the completion of the asbestos-control  work.

Completely isolate the Work Area from other parts of the building
so as  to  prevent asbestos-containing  dust or debris  from passing
beyond  the isolated  area.    Should  the  area   beyond  the  Work
Area(s)  become  contaminated   with  asbestos-containing  dust  or
debris  as a   consequence of  the  work,   clean  those  areas  in
accordance  with  the  procedures  indicated  in  Section  01711.

CRITICAL BARRIERS;

Completely  Separate the  Work Area  from  other  portions  of the
building,  and  the  outside by  closing  all  openings  with sheet
plastic  barriers at  least 6 mil  in  thickness,  or  by  sealing
cracks leading out of Work Area with duct tape.

Individually seal all  ventilation  openings (supply and exhaust) ,
lighting  fixtures,   clocks,   doorways,  windows,  convectors  and
speakers, and  other openings into  the Work Area  with duct tape
alone or with  polyethylene sheeting  at least  6 nil in thickness,
taped securely in place with  duct  tape.   Maintain seal until all
work including Project Decontamination is completed.   Take care
in sealing  of  lighting fixtures  to  avoid melting  or burning of
sheeting.

Provide  Sheet  Plastic barriers  at least  6  nil   in  thickness as
required to seal openings completely  from the  Work Area into
adjacent areas.  Seal the perimeter of all sheet plastic barriers
with duct tape or spray cement.

Mechanically Support sheet plastic  independently  of duct tape or
spray cement seals so that seals do not support the weight of the
plastic.   Following are  acceptable  methods of supporting sheet
plastic  barriers.   Alternative  support methods  may be  used if
approved in writing  by the Owner's Representative.

           in  Section 01711  Project  Decontamination is  complete
     is been certified by the Project Administrator.

AIR MONITORING:

To  determine  if  the   elevated  airborne   asbestos   structure
concentration   encountered  during abatement operations  has  been
reduced to the specified level,  the Owner will secure samples and
analyze them according to the following  procedures.

          CHOOSE ONE OF THE  FOLLOWING SEQUENCE  OF  PROCEDURES AND
          DELETE THE OTHER.   THE  FIRST  IS BASED UPON  SEQUENTIAL
          SAMPLING FIRST  BY  PCM FOLLOWED BY TEM.    THE SECOND IS
          BASED UPON SIMULTANEOUS  SAMPLING WITH CLEARANCE  BY PCM
          REQUIRED BEFORE TEM SAMPLES ARE ANALYZED.

     Aggressive sampling  procedures  as  described  below will  be
     followed.

     PCM samples will be secured as indicated  below. If  the  area
     meets the clearance criteria  TEM sampling will  proceed.

     Aggressive sampling procedures will  be  repeated.

     TEM samples will be secured and  analyzed  as indicated  below.

     Work  Area  Clearance:    upon  meeting   the   TEM  Clearance
     requirements   the   work   of   Section  01711    Project
     Decontamination can continue.

          FOLLOWING  PROCEDURE IS BASED UPON  PCM AND TEM SAMPLES
          BEING TAKEN SIMULTANEOUSLY

     Aggressive sampling  procedures  as  described  below  will  be
     followed.

     PCM and TEM samples will  be secured as  indicated below.   PCM
     samples will  be analyzed  and  TEM samples  will be transmitted
     to the laboratory.   If  the area  meets the clearance  criteria
     by PCM the TEM  analysis will  proceed.

     Work  Area  Clearance;    upon   meeting   the  TEM  Clearance
     requirements   the  work  of   Section  01711    Project
     Decontamination can continue.

          AGGRESSIVE SAMPLING IS APPROPRIATE  ONLY  FOR  CLEARANCE
          OF  ABATEMENT   PROJECT  AREAS  THAT  ARE   ISOLATED  FROM

                THIS HAS  BEEN ATTEMPTED HAVE RESULTED IN SERIOUS
           [ONTAMINATION  PROBLEMS  FOR  THE  INVOLVED  SPACE  AND
              XXJNDING AREAS.

           SAMPLING:
All  Air  Samples  will  be   taken  using  aggressive  sampling
techniques as follows:

          THERE ARE NO  STANDARDS  AVAILABLE FOR FLOW RATE OF LEAF
          BLOWERS OR LARGE FANS.  HOWEVER THIS INFORMATION IS NOT
          CRITICAL TO THE SUCCESS OF THE PROCEDURE.

     Before sampling  pumps  are started the  exhaust from forced-
     air  equipment  (leaf  blower   with  an  approximately  1
     horsepower electric notor) will  be swept against all walls,
     ceilings,  floors,  ledges  and  other  surfaces in  the  room.
     This procedure  will be continued for 5  minutes  per 10,000
     cubic feet of room volume.

     One  20   inch  diameter  fan per  10,000 cubic  feet  of  room
     volume   will  be   mounted   in   a   central  location  at
     approximately 2  meters  above floor,  directed toward ceiling
     and  operated  at low speed for the entire  period of sample
     collection.

     Air samples will be collected in areas subject to normal air
     circulation away from  room  corners,  obstructed  locations,
     and sites near windows, doors of vents.

     After air  sampling  pumps  have been shut  off,   fans will be
     shut off.

SCHEDULE OF AIR SAMPLES:

          CONSULT  WITH   THE ENVIRONMENTAL CONSULTANT  SUPPLYING
          PROJECT  ADMINISTRATORS  AND  LABORATORY WORK  ABOUT THE
          SPECIFIC EQUIPMENT AND ANALYTICAL METHODS AVAILABLE FOR
          THE  PROJECT.    EDIT  THE  FOLLOWING  TO  SUIT  SPECIFIC
          PROJECT  REQUIREMENTS  AND  AVAILABILITY  OF  ANALYTICAL
          TOOLS.

General;    The  number   and volume  of air   samples  taken  and
analytical methods used  by  the Owner  will  be  in accordance with
the following schedule.  Sample volumes given may vary depending
upon the analytical instruments used.

          THE  AHERA  REGULATION  FOR  PCM  CLEARANCE  IN SCHOOLS.
          OTHER ANALYTICAL METHODS COULD  BE USED FOR  NON-SCHOOL
          PROJECTS  OR AS  PRE-CLEARANCE  LEADING  TO TEM ANALYSIS.
          HOWEVER,   THE   AHERA  REGULATION   IS   A  VERY  STRONG
          STATEMENT  FROM  THE  EPA  ON  THE  STANDARD OF CARE AND
          ACCEPTABLE METHODS OF ACHIEVING THAT STANDARD.

Analysis;  Fibers on each  filter will be measured using the NIOSH
Method 7400  entitled "Fibers"  published in the  NIOSH  Manual  of
Analytical Methods, 3rd Edition, Second Supplement, August 1987.

Fibers:  referred to in this section include fibers regardless  of
composition  as  counted by the phase contrast  microscopy method
used.

          THE  FOLLOWING  DESCRIBES CLEARANCE  TESTING AS  REQUIRED
          BY  THE AHERA  REGULATION  FOR SCHOOLS.    THIS  IS ALSO
          BECOMING  A  DE  FACTO STANDARD  FOR  PUBLIC  NON-SCHOOL
          BUILDINGS.   WORK  IN  INDUSTRIAL SETTINGS MAY  HAVE A
          DIFFERENT  STANDARD  THAN THAT FOR  A  PUBLICLY  OCCUPIED
          BUILDING.

In  each  homogeneous work area  after completion  of all  cleaning
work,  a  minimum  of  13  samples  will be  taken and  analyzed as
follows:

          THE  SAMPLE  VOLUME  GIVEN  BELOW   IS  NOT  THE   LOWEST
          REQUIRED  BY THE AHERA REGULATION.    IT  IS  THE  LOWEST
          VOLUME  ALLOWED  FOR   10   GRID  OPENINGS  TO  GIVE  AN
          ANALYTICAL SENSITIVITY OF 0.005 STRUCTURES/CC.   10 GRID

          LABORATORIES  PERFORMING  THIS  TYPE   OF   ANALYSIS.
          ADHERENCE  TO THIS  VOLUME  MAY  GIVE  RISE  TO   GREATER
          REPRODUCABILITY  OF   RESULTS.     THE  MINIMUM  VOLUME

    ;ase Criteria; Decontamination of the work site is complete if
either of the following two sets of conditions are met:

     Work Areg Samples are below filter background levels

          All Work  Area  sample  volumes  are  greater than  1,199
          liters for a 25 mm. sampling cassette.

          The average concentration  of  asbestos on the  five Work
          Area  Samples   does  not  exceed  the  filter  background
          level of 70 structures  per square millimeter  of filter
          area.

     Work  Area  Samples  are not  statistically  different  from
     Outside samples

          All sample volumes  except for blanks  are  greater than
          560 liters for a 25 mm. sampling cassette.

          The average asbestos concentration  of the  three blanks
          is below the  filter background  level  of  70  structures
          per square millimeter of filter area.

          Average asbestos  concentrations  in Work Area  Samples
          are not statistically  different  from  Outside samples,
          as determined by the Z-test calculation found in 40 CFR
          Part  763,  Subpart  E,  Appendix  A  (Z  is  Less  that  or
          equal to 1.65)

If  these conditions  are  not met  then  the  decontamination  is
incomplete and  the cleaning  procedures  of Section 01710 shall be
repeated.

Termination  of  Analysis;    if  the arithmetic  mean  (average)
asbestos concentration  on the blank filters exceed 70  structures
per square millimeter of  filter  area the analysis will  cease and
new samples collected.

WORKER PROTECTION;

Before  beginning work  with  any  material  for  which  a  Material
Safety  Data Sheet  has  been  submitted  provide  workers  with  the
required  protective  equipment.   Require  that  appropriate
protective equipment be used at all times.


WET REMOVAL:

Thoroughly  wet  to   satisfaction   of  Owner's  Representative
Aasbestos-Containing Materials  to be removed prior  to stripping
and/or   tooling  to   reduce   fiber  dispersal   into   the  air.
Accomplish  wetting  by a  fine spray  (mist)  of  amended  water  or
removal  encapsulant.   Saturate material  sufficiently  to  wet  to
the substrate  without causing excess dripping.   Allow  time  for
amended  water  or  renoval  encapsulant  to  penetrate  material
thoroughly. If  amended  water is used,  spray  material  repeatedly
during the work process to maintain a continuously wet  condition.
If a removal encapsulant is used,  apply in strict accordance with
manufacturer's written instructions.   Perforate  outer covering  of
any installation which has  been painted and/or  jacketed  in order
to allow penetration  of amended water or  removal encapsulant,  or
use  injection  equipment  to  wet  material  under  the   covering.
Where  necessary,  carefully  strip   away  while  simultaneously
spraying amended water or removal  encapsulant on the  installation
to minimize dispersal of asbestos  fibers into the air.

  prayed-fiber or dry mixed materials are those
 where  the dry  formulation of  mineral  fibers,
 portland cement, binders, etc., are conveyed by
 low-pressure air to  the  spray nozzle and then
 mixed  with water.   Both cemeiitilious  and
 sprayed-fiber products  contain  one  form of

that, when mixed with water, with or without
aggregate, provides  the plasticity anc the cohe-
sive and adhesive properties necessary for the

thai arc considered less subject to physical abuse
than exposed fireproofing.

Other cementitious  products are specified
under exposed sprayed-on fireproofing along with
intumeacent mastic fireproofing products.

Intumescent mastics are product? intended for
exposed structural steel members where a thin,
durable, impact- and abrasion-resistant coating is
desired    When exposed  to  fire,  intumesccnt
mastics expand to produce a thick, carbonaceous
foam  that protects the steel by thermally insula-
ting it and shielding it against radiation.

Encapmilants include materials that are spray
applied  either  over  previously  applied  fire-
resistive fibrous and cementitious formulations or
to structural members  from  which  previously
applied  materials  had  been removed.   In the
latter case they are  referred to as lockdown
encapsulants. Typically, encapsulants arc part of
a separate asbestos-abatement contract.

The arrangement of products in this Section
into two groups, concealed and exposed, is not
intended to imply that products in one group are
not suitable for the other.  Instead it simplifies
specifying different products and their extent. It
also helps to  specify  both  cementitious and
sprayed-fiber products on a competitive basis for
concealed  applications  whore  compliance  with
selected  physical  properties  establishes  the
criteria for acceptance.

While this approach is also suitable for exposed
fireproofing materials, the difference in price and
qualities between the various products makes it
difficult to specify two or more products that are
cost-competitive with  one another.   Finally, it
recognizes that  concealed applications represent
the major volume of sprayed-on fireproofing in-
stalled in buildings  While products for exposed
applications arc certainly suitable for architec-
tural uses, they find a larger market in industrial
projects.

PERFORMANCE STANDARDS

response  chara
assemblies  for
resistance ratings  ASTM E 119 test results are
typically  compared  with   the  fire resistive
requirements established by the authority having
jurisdiction and  form the basis  for selecting a
particular fire-resistive design.  Essentially the
ASTM E 119 test method measures performance
under fire-«xposure conditions in a controlled
laboratory  environment  and  not necessarily
under conditions of normal use   As a result,
product selection must take into account prop-
erties other than those measured by fire-response
testing  in selecting  a  fireproofing  that  will
remain functional during .1 building's service life.

Restrained  and  unrestrained  ratings for
assemblies and for individual beams arc typically
listed for each firc-resis'.ivc design in the UL Fire
Resistance Directory.  Both  the  UL publication
and ASTM E 119 include a guide for determining
conditions  of  restraint  for  floor  and  roof
assemblies and  for individual beams   Where
conditions of restraint do not comply with the
definition for restraint piven  in the UL publi-
cation, an unrestrained condition is assumed to
exist   An option is  provided in the text for the
Contractor to submit shop  drawings  on  which
restrained and unrestrained conditions are desig-
nated by a qualified professional engineer paid by
the Contractor  Do not retain this provision  if
the structural drawings show these conditions or
if  the Architect  is  required by  law  to assume
responsibility for such determinations.

The in-place serviceability of fireproofing is
determined  by the  various  physical properties
from the tests for cohesion/adhesion, compressive
strength, etc.. specified in the Text for concealed
fireproofing.   Currently there are no national
standards established for minimum allowable per-
formance levels  for these properties and there
seems little inclination on the part of manufac-
turers to establish any.

Whether or  nut to accept the properties
specified in this Section as  satisfactory for  a
specific application  mu«t  remain the decision of
users based on a review of applicable codes, input
from  manufacturers based  on their  experience

 SELECTION CONSIDERATIONS

 The  major consideration in selecting which
 products to specify for both conc«aled and ex-
 posed application? is anticipating what exposure
 conditions  will  prevail during the life of the
 structure

 Concealed applications behind construction
 whose removal is unlikely during the life of the
 building or iu locations not requiring access for
 servicing of  building  environmental  systems
 appreciably reduce the risk of abrading or damag-
 ing the fireproofing  This contrasts with spaces
 over accessible ceilings when* continual mainte-
 nance of wiring, air ducts, and piping exposes the
 fireproofing to possible damage

 Specific conditions affecting choice of products
 include the following:

 •   Where the ceiling space is either a supply 01*
    return air plenum, air movement could er

is applied to all structural members or to selected
ones only. Although specifying extent by includ-
ing a schedule or inserting requirements in the
Text is possible, it is recommended to indicate on
the drawings the location of each form of treat-
ment along with exact references to the  various
fire-resistive designs that apply.  Where more
than one fireproofing product is acceptable for a
given location, indicate the fire-resistive design
that applies to each product.

Information  about  fire-resistance  ratings
and the corresponding UL design numbers is best
placed on the drawings because the Building Offi-
cial's plan reviewers and Geld inspectors will look
for it there.  Duplicating this information in the
specifications only increases the chances of pro-
viding conflicting data that could result in change
orders cr,  if initially  included  in th«  specifi-
cations, in having to copy  it laboriously onto all
the permit set*.

Achieving   compliance  with   UL-reted
designs typically requires strict compliance with
the details  listed  in  the  UL  fire  Resistance
Directory.  Any attempt  to avoid  listing the
applicable UL designs by a simpler alternative,
such as an hourly rating of minimum density and
thickness, \a unlikely  to satisfy the authorities
nor achieve the fire-resistance rating  required.

Detailing is important  where appearance is
concerned.   For columns  and  beams,  indicate
whether to box out with metal lath or to follow
the contour of the individual member  Where
sharp corners are required, indiratn corner beads
if the)' not required for firw-resistance rating but
are permitted

 With regard to asbestos-containing  materials, abatement
 refers to a response action taken to control the potential for
 fiber release.   Abatement  typically  includes removal.
 encapsulation or enclosure of asbestos-containing material.

 American Board of Industrial Hygiene.

 Asbestos-Containing Material.

 The general application or use of asbestos for the control of
 sound due to its lack of reverberant surfaces.

 A finishing material in a building usually found in the ceiling
 or walls for the purpose of noise control.

 A level of airborne fibers specified by OSHA as a warning or
 alert level.  It is 0.1 fibers per cubic centimeter of air, eight-
 hour, time-weighted average, as measured by phase contrast
 microscopy.

 Air Filtration Unit.  Usually refers to machines used to provide
 ventilation and a negative static pressure differential within a
 completely enclosed asbestos work area. An AFD usually
 consists of a fan system to draw air through a special set of
 filters—a gross prefilter, an intermediate filter and  a HEPA
 filter—and exhaust dean air to the outside.  AFDs are rated
 by  the amount of air that can be drawn through them in a
 given amount of time, which is expressed in cubic feet of air
 per minute(e.g.. 2.000 CFM).  Loaded or clogged filters can
 seriously affect the displacement volume capability or the
 efficiency of these devices.

 Air sampling which takes place after final cleanup while the
 air is being physically agitated  to produce a 'worst-case*
 situation.

 Asbestos  Hazard  Emergency  Response Act.  Refers  to
 authorized legislation and administrative rules promulgated
 by the US EPA to control asbestos in  all  schools, public and
 private, nonprofit, grades K-12.  AHERA  requires all  school-
 owned buildings to be  physically inspected  for asbestos-
 containing  materials  and  a  suitable, building-specific
 asbestos management  plan be drafted and  implemented.
 Refer to 40 CFR 763 for further Information.

contaminant(s) from the ambient air.   They include both
negative pressure and powered respirators.  No type of air
purifying respirator will protect the wearer from low oxygen
atmospheres.

Determination of the amount of asbestos fibers suspended in
a given amount of air.

A respirator that is connected to a compressed breathing air
source by a hose.

A universally-accepted procedure developed for the purpose
of solving a particular problem.  Algorithms developed for
asbestos provide a numerical index for evaluating a degree of
hazard in a particular area.  The  Sawyer Algorithm and the
Ferris Index are two, but neither are widely used today.

Highly-specialized mobile cells  in the lungs that attempt to
engulf and digest such lung hazards as dusts or fibers.

Air sacs located in dusters around the respiratory bronchioles
of the lungs.  This is the area in which true respiration takes
place.

 hydrated mineral silicates that possess a unique crystalline
 structure, are incombustible in air,  and are separable  into
 fibers.   Asbestos includes the asbestiform varieties of
 chrysolite (serpentine), crocidolite  (riebeckite),   amosite
 (cummingtonite-grunerite),  anthophydite, and actinolite.

 Procedures to control fiber release from asbestos containing
 materials in buildings.

 Minimizing the generation  of airborne asbestos fibers until a
 permanent solution is developed.

 A decision tool which can be used to determine the extent of
 the asbestos hazard that exists  in a building, and which can
 also be used to develop corrective actions.

                     Procedures for the Use of Negative Pressure
                         Systems for Asbestos Abatement
J.1 Introduction

This appendix provides guidelines for the use of negative pressure systems in removing
asbestos-containing materials from buildings. A negative pressure system is one in
which static pressure in an enclosed work area is lower than that of the environment outside
the containment barriers.

The pressure gradient is maintained by moving air from the work area to the environment
outside the area via powered exhaust equipment al a rate that will support the desired air flow
and pressure differential. Thus, the air moves into the work area through designated access
spaces and any other barrier openings Exhaust air is filtered by a high-efficiency paniculate
air (HEPA) filter to remove asbestos fibers.

The use of negative pressure during asbestos removal protects against large-scale release of
fibers to the surrounding area in case of a breach in the containment  barrier. A negative
pressure system also can reduce the concentration of airborne asbestos  in the work area by
increasing the dilution ventilation rate (i e.. diluting contaminated air in  the work area with
uncontaminated air from outside) and exhausting contaminated air through HEPA filters The
circulation of fresh air through the work area reportedly also improves worker comfort, which
may aid the removal process by increasing job productivity
J.2 Materials and Equipment
    *


J.2.1  The Portable. HEPA-Fltered. Powered Exhaust Unit

The exhaust unit establishes lower pressure inside than outside the enclosed work area
during asbestos abatement. Basically, a unit (see Figure J-1) consists of a cabinet with an
opening at each end, one for air intake and one for exhaust. A fan and a series of filters are
arranged inside the cabinet between the openings The fan draws contaminated air through
the intake and filters and discharges clean air through the exhaust.

Portable exhaust units used for negative pressure systems in asbestos abatement projects
should meet the following specifications


J.2.1.1 Structural Specifications

The cabinet should  be ruggedly constructed and made of durable  materials to withstand
damage from rough handling and transportation The width of the cabinet should be less than
30 inches to fit through standard-size  doorways The cabinet must be appropriately sealed to
prevent asbestos-containing dust from being emitted during use. transport, or maintenance.
There should be easy access to all air filters from the intake end. and the filters must be easy

to replace. The unit should be mounted on casters or wheels so it can be easily moved. It also
should be accessible for easy cleaning.
J-2.1.2  Mechanical Specifications
J.2.1.2.1 Fans

The fan for each unit should be sized to draw a desired air flow through the filters in the unit
at a specified static pressure drop The unit should have an air-handling capacity of 1.000 to
2,000 rtVmm (under "clean" filter conditions). The fan should be of the centrifugal type.

For large-scale abatement projects, where the use of a larger capacity, specially designed
exhaust  system  may  be more practical than  several  smaller  units, the fan  should be
appropriately sized according to the proper load capacity established for the application, i.e..
                 Total ftVmin (load) =
Volume of air in ft3 x air changes/hour

            60 min/hour
                                          J-2

-------
Smaller-capacity units (e.g.. 1.000 fiVmin) equipped with appropriately sized fans and filters
may be used to  ventilate smaller work areas  The desired air flow could be achieved with
several units
J.2.1.2.2 Filters

The final filter must be the HEPA type. Each filter should have a standard nominal rating of at
least 1.100 ft'/min with a maximum pressure drop of 1 inch H»0 clean resistance. The filter
media (folced into closely pleated panels) must be completely  sealed on all edges with a
structurally rigid frame and cross-braced  as required. The exact dimensions of the filter
should correspond with  the  dimensions of  the  filter housing  inside  the cabinet or  the
dimensions of the  filter-holding frame. The recommended standard size MEPA filter is 24
inches high x 24 inches wide x 11-1/2 inches deep. The overall dimensions and squareness
should be withm 1 /8 inch

A continuous rubber gasket must be located between the filter and the filter housing to form a
tight seal. The gasket material should be 1/4 me?" thick and 3/4  inch wide

Each filter  should be  individually  tested  and  certified by the  manufacturer to have an
efficiency of not less than 99.97 percent when challenged with 0.3-j/m dioctylphthalate (OOP)
particles Testing should be in accordance with Military Standard  Number 282 and Army
Instruction Manual 136-300-175A  Each filter should bear a UL586 label to indicate ability to
perform under specified conditions.

Each filter should be marked with  the name of the manufacturer,  serial number, 'air flow
rating, efficiency and resistance, and the direction of test air flow.

Prefilters. which protect the final fitter by removing the larger particles, are recommended to
prolong the operating life of the HEPA filter. Prefilters prevent the premature loading of the
HEPA filter They can also save energy and cost One (minimum) or two (preferred) stages of
prefiltration may be used The first-stage prefilter should  be a low-efficiency type (e.g., for
parades 10  prn and larger). The second-stage (or  intermediate) filter should have a medium
efficiency (e.g .  effective for particles down to 5 pn) Various types of filters and fitter media
for prefiltration applications are available from many manufacturers. Prefilters and inter-
mediate filters should be installed either on or in the intake grid  of the unit and held in place
with special housings or clamps.


J.2.1.2.3 Instrumentation

Each unit should be  equipped wrth a Magnehelic gauge or manometer to measure the
pressure drop across the filters and indicate when filters have become loaded and need to be
changed. The static pressure across the filters (resistance) increases as they become loaded
with dust, affecting the ability of the unit to move air at its rated capacity.


J.Z1.3 Electrical
J.2.1.3.1 General

The electrical system should have a remote fuse disconnect The fan motor should be totally
enclosed, fan cooled,  anc1 the nonoverloadmg type The unit must use a standard 115-V,

-------
 single-phase. 60-cycle service All electrical components must be approved by the National
 Electrical Manufacturers Association (NEMA) and Underwriter's Laboratories (UL)
 J.2.1.3.2  Fans

 The motor, fan, fan housing,  and cabinet should be grounded. The unit should have an
 electrical  (or mechanical) lockout to prevent the fan from operating without a HEPA filter.


 J.2.1.3.3  Instrumentation

 An automatic shutdown system that would stop the fan in the event of a major rupture in the
 HEPA filter of blocked air discharge is recommended. Optional warning lights are recom-
 mended to indicate normal operation, too high of a pressure drop across the filters (i.e., filter
 overloading), and too low of a pressure drop (i.e.. major rupture in HEPA filter or obstructed
 discharge) Other optional instruments include a timer and automatic shut-off and an elapsed
 time meter to show the total accumulated hours of operation.


 J.3 Setup and Use of e Negative Pressure System


 J.3.1  Preparation of the Work Area


 J.3.1.1  Determining the Ventilation Requirements for a Work Area

 Experience with negative pressure systems on asbestos abatement projects indicates a
 recommended rate of one air change every 15 minutes. The volume (in ft3) of the- work area is
 determined by multiplying the floor area by the ceiling height. The total air flow requirement
 (in ftVmin) for the work area is determined by dividing this volume by the recommended air
 change rate (i.e., one air change every 15 minutes).*

                  Total ftVmin = Volume of work area (in ft3)/15 min

 The number of units needed for the application is determined by dividing the total rtVmm by
 the rated capacity of the exhaust unit.

            Number of units needed = [Total ftJ/min]/(Capacity of unit (in ft3)]


 J.3.1.2  Location of Exhaust Units

 The exhaust unit(s) should be  located so that makeup air enters the work area primarily
 through the decontamination facility and traverses the work area as much as possible. This
 may be accomplished by positioning the exhaust unit(s) at a maximum  distance from the
 worker access opening or other makeup air sources.

 Wherever  practical, work area  exhaust units can be located on the floor  in or near unused
doorways  or windows The end of the unrt or its exhaust duct should  be placed through an
opening in the plastic barrier or  wall covering The plastic around the unit or duct should then
be sealed with  tape
'The recommended air exchange rate « based on engineering judgment
                                         J-4

-------
 Each unit must have temporary electrical power (115V AC), tf necessary, three-wire extension
 cords can supply power to a unit The cords must be in continuous lengths (without splice), in
 good condition, and should not be more than 100 feet long. They must not be fastened with
 staples, hung from nails, or suspended by wire Extension cords should be suspended off the
 floor and out of workers' way to protect the cords from damage from traffic, sharp objects, and
 pinching.

 Wherever possible, exhaust units should be vented to the outside of the building. This may
 involve the use of additional lengths of flexible or rigid duct connected to the air outlet and
 routed to the nearest outside opening. Windowpanes may have to be removed temporarily.

 If  exhaust  air cannot be vented  to  the outside of the building or if  cold temperatures
 necessitate measures to conserve heat and minimize cold air infiltration, filtered air that has
 been exhausted through the barrier may be recirculated into an adjacent area. However, this
 is  not recommended.

 Additional makeup air may be necessary to avoid creating too high of a pressure differential.
 which could cause the plastic coverings and temporary barriers to  "blow in." Additional
 makeup  air also  may be needed  to move air  most  effectively through the work  area.
 Supplemental makeup air inlets may be made by making openings in the plastic sheeting that
 allow air from outside the building into the work area. Auxiliary makeup air inlets should be as
 far as possible from the exhaust unit(s) (e.g.. on an opposite wall), off the floor (preferably near
 the ceiling), and away from barriers that separate the work area from occupied clean areas
 They should be reseated whenever the negative pressure system is turned off after removal
 has started. Because the pressure differential (and ultimately the effectiveness of the system)
 is  affected by the adequacy of makeup air, the" number of auxiliary air inlets should be kept to a
 minimum to maintain negative pressure.  Figure J-2 presents examples of negative pressure
 systems denoting the location of HEPA-filtered exhaust  units and the direction of air flow


 J.3.2 Use of the Negative Pressure System


 J.3.2.1 Testing the System
                                       «•
 The negative pressure system should be tested before any asbestos-containing material is
 wetted or removed. After the work area has been prepared, the decontamination facility set
 up. and the exhaust unrt(s) installed, the unit(s) should be started (one at a time). Observe the
 barriers and plastic sheeting. The plastic curtains of the decontamination facility should move
 slightly in toward the work area. The use of ventilation smoke tubes and a rubber bulb is
 another easy and inexpensive way to visually check system performance and direction of air
flow through openings in the barrier. Another test is to use a Magnehelic gauge (or  other'
 instrument) to measure the static pressure differential across the barrier. The measuring
device must be sensitive enough to detect a relatively low pressure drop. A Magnehelic gauge
with a scale of 0 to 0.25 or 0.50 inch of H*O and 0.005 or 0.01 inch graduations is generally
adequate. The pressure drop across the barrier is measured from the outside by punching a
small hole in the plastic barrier and inserting one end of a piece of rubber or Tygon tubing. The
other end of the tubing is connected to the "low pressure" tap of the instrument. The "high
pressure" tap must be open to the  atmosphere. The pressure is read directly from the scale.
After the test is completed, the hole in the barrier must be patched.

-------
J.3.2.2 Die of System During Removal Operations

The exhaust units should be started just before beginning removal (i e . before any asbestos-
containing material is disturbed). After removal has begun, the units should run continuously
to maintain a constant negative pressure until decontamination of the work area is complete.
The units should not be turned off at the end of the work shift or when removal operations
temporarily stop.

Employees should start  removing the asbestos material at a  location  farthest from  the
exhaust units and work toward them. If an electric power failure occurs, removal must Slop
immediately and should not resume until power is restored and exhaust units are operating
again.

Because airborne asbestos fibers are microscopic in size and tend to remain in suspension for
a long tim», the exhaust units must keep operating throughout the  entire removal and
decontamination processes. To ensure continuous operation, a spare unit should be available.

After asbestos removal equipment has been moved from the work area, the plastic sheeting
has been cleaned, and all surfaces in the work area have been wet-cleaned, the exhaust units
can be allowed to run for at least  another 4 hours to  remove airborne fibers that may have
been generated during wet removal and cleanup and to purge the work area with clean
makeup air. The units may be allowed to run for a longer time after  decontamination.
particularly if dry or only partially wetted asbestos material was encountered during removal.


J.3.2.2.1 Filter Replacement

All filters must be accessible from the work area or "contaminated" side of the barrier. Thus,
personnel responsible for changing fillers while the negative pressure system is in use should
wear approved respirators and other protective equipment. The operating life of a HEPA filter
depends on the level of paniculate contamination  in the environment in which it is used.
During use. filters will become loaded with dust, which increases resistance to air flow  and
diminishes the air-handling capacity of the unit. The difference in pressure drop across the
filters between "clean" and "loaded" conditions (AP) is a convenient means of estimating the
extent of air-flow resistance and determining when the filters should be replaced.

When AP across the filters (as determined by the Magnehelic gauge or manometer on  the
unit) exceeds 1.0 inch of HjO. the prefitter should be  replaced first. The prefitter. which  fan
suction will generally hold in place  on  the  intake grill, should be removed with the unit
running by carefully rolling or folding in its sides. Any dust dislodged from the prefilter during
removal will be collected on the intermediate filter. The used prefilter should be placed inside
a plastic bag. sealed and labeled, and disposed of as asbestos waste. A new prefilter is then
placed on the intake grill. Filters for prefiltration applications may be purchased as individual
precut panels or in a roll of specified width that must be cut to size.

If the AP still exceeds 1.0 inch of H»0 after the prefilter has been replaced, the intermediate
filter is replaced. With the unit operating, the prefilter should be removed, the intake grill or
filter access opened, and the intermediate  filter removed.  Any dust  dislodged from  the
intermediate filter during removal will be collected on the HEPA filter. The  used intermediate
filter should be placed m a sealable plastic bag (appropriately  labeled) and disposed of as
asbestos waste.  A new replacement filter is then  installed and the grill or access closed.
Finally, the prefilter on the intake grill should  be replaced
                                         J-7

-------
The HEPA filter should be replaced if prefilter and/or intermediate filter replacement does not
restore the pressure drop across the filters to its original clean resistance reading or if the
HEPA filter becomes damaged. The exhaust unit is shut off to replace the HEPA filter, which
requires removing the prefilter first, then opening the intake grill or filter access, and finalry
removing the HEPA filter from the unit  Used HEPA filters should be placed in a sea (able
plastic bag (appropriately labeled) and disposed of  as asbestos waste  A new HEPA fitter
(structurally identical  to the original filter)  should  then be installed. The intake grill and
intermediate filter should be put back in place, the unit turned on, and the prefilter positioned
on the intake grill. Whenever the HEPA filter is replaced, the prefilter  and  inter mediate filter
should also be replaced

When several exhaust units are  used to ventilate a work area, any air movement through an
inactive unit during the HEPA filter replacement will be into the work area. Thus, the risk of
asbestos fiber release to the outside environment is controlled

Any filters used in the system may be replaced more frequently than the pressure drop across
the filters indicates is necessary. Prefilters. for example, may be replaced two to four times a
day or when accumulations of paniculate matter become visible Intermediate filters must be
replaced once every day or so. and the HEPA filter may be replaced at the  beginning of each
new project. (Used HEPA filters  must be disposed of as asbestos-containing  waste.) Condi-
tions  in the work area dictate the frequency of filter changes. In a work area where fiber
release is  effectively controlled  by thorough wen ing and good work practices, fewer filter
changes may be required than in  work areas where the removal process is not well controlled.
It should  also be  noted that the collection efficiency of a filter generally improves as
paniculate accumulates on it. Thus, filters can be used effectively until resistance (as a result
of excessive paniculate loading) diminishes the exhaust capacity of the unrt.


J.3.2.3 Dismantling th« System

When a final inspection and  the results of final air tests indicate that the area has been
decontaminated, all filters of the exhaust units should be removed and disposed of properly
and the units shut off. The remaining barriers between contaminated and clean areas and all
seals on openings into  the work area  and fixtures may be removed  and disposed of as
contaminated waste. A final check should be made to be sure that no dust or debris remain on
surfaces as a result of dismantling operations.

    OVERVIEW  OF GLOVEBAGS AND THE  GLOVEBAG PROCEDURE

 GENERAL DESCRIPTION

 A glovebag typically consists of a 3- to 12-mil polyethylene or polychloride (PVC) bag fitted
 with long latex sleeves and gloves, a tool pouch, and small opening(s) which may be used
 for insertion of  water sprayers and/or HEPA vacuum  nozzles.  A typical glovebag  is
 approximately 40- to 50-inches wide by 48- to 60-inches Jong.  Glovebags can be obtained
 in various shapes and sizes. For example,  special glovebags are available for work on
 vertical pipes.  Commercially-available glovebags are prelabeled  in accordance with
 OSHA, EPA and DOT requirements.

 Glovebags are good for taking off the insulation around a valve, pipe etoow or pipe.  The
 glovebag is sealed air tight to the pipe to form a containment  barrier.  One worker keeps
 the material wet using the spray wand Inserted into the bag, while another worker removes
 the material using the attached glove.  Workers wear  respirators and disposable clothing
 white performing glovebag work.

 Glovebags can only be used on cool pipes for two reasons. Polyethylene  bums at 150°,
and use of water on a hot pipe could create steam which might bum  the worker or cause
the glovebag to rupture. Glovebags can be used on most hot water systems but should not
be used on live steam lines.

OSHA REQUIREMENTS FOR USE

In accordance with OSHA regulations, the procedures which must be followed depend on
the amount of material being removed and the nature of the work being done. Small-
scale, short-duration maintenance jobs where a small amount of asbestos is removed to
repair a valve or a pipe (one glovebag only) do not require the use of a negative pressure
enclosure.  They  are, however, subject to the provisions outlined in Appendix Q of the
OSHA Construction Industry Standard (29 CFR 1926.58).

These provisions require the employer to establish a written operations plan describing the
procedure.  Other required procedures include forming  an air-tight seal around the pipe;
using half mask respirators; wetting the ACM; cleaning the surfaces after ACM is removed;
encapsulating exposed ends of remaining  insulation;  evacuating  the glovebag with a
HEPA vacuum; and disposing of the glovebag after one use.

The main difference in glovebag procedure for large-scale asbestos abatement operations
is the OSHA requirement to establish negative air pressure within the containment area.
There are two ways to establish a negative air pressure containment.  A variable speed
HEPA-filtered vacuum  or equivalent can be inserted in the glovebag.  Alternately, the room
the project is In can be propped as a containment area and a pressure differential can be
obtained using HEPA air filtration units.

The tools and procedures for conducting glovebag removal for small-scale, short-duration
projects are described below.   If glovebags are used for large-scale abatement, then
provisions for establishing a negative pressure enclosure would need to be added to these
procedures.

BEFORE STARTING THE PROJECT

Two persons are typically required to perform a glovebag removal project. A third person
is often available to assist with supplies, keep unwanted visitors out of area, and possibly
to conduct the air monitoring.  Each of these team members should have received training
on the use and Umitations of glovebag removal projects. They should also be included in
the respiratory protection program and medical surveillance programs.

Before any work begins, all necessary materials and supplies should be brought into  the
work area.  This work area should be roped off and danger signs posted on the perimeter
to minimize the chance of visitors entering this area.  Barrier tape (3-inch) with a preprinted
asbestos warning works well for this purpose. The HVAC system serving the work area
should be shut down, if possible. Employees should be trained hi emergency procedures
in the  event the glovebag ruptures.  These  emergency procedures usually include wet
cleaning and/or HEPA  vacuuming  procedures and a shower available at a remote
location. With this phase completed, the following generic guidelines may be used  for
most pipe lagging projects.  It is important not to attempt to conduct glovebag removal on
hot pipes (over 120°F) due to the posstoility of the bags melting over the worker's hands
and arms.  Some manufacturers are currently experimenting with  the development of
special 'high-temperature" gtovebags to allow removal from hot surfaces; however, it is still
necessary to  exercise extreme caution when dealing with  these types of situations.
(Polyethylene will melt at 150°F.)

REMOVEL PROCEDURES

  1.  Following the manufacturer's directions, mix the surfactant with water in the garden
     sprayer.

  2.  Have each employee put on a high efficiency cartridge respirator approved for use
     against asbestos and check the face fit.

  3.  Have each employee put on a disposable full body suit  Remember, the hood goes
     over the respirator straps.

  4.  Check the pipe where the work will be performed.  If it is damaged (broken lagging.
     hanging,  etc.), wrap the  entire length of the pipe in  polyethylene plastic and
     'candystripe' it with duct tape.  A common error when doing glovebag work  is
     forgetting that loose pipe lagging several feet or even several yards away from the
     glovebag work may  be jarred loose by the removal activity.  This is one  of the
     common causes of high airborne fiber concentrations during glovebag work.  Another
     problem is failure to clean up debris on the floor and other surfaces which has
     accumulated  and contains asbestos. If the pipe is undamaged, it is still  necessary to
     place one layer of duct tape around the pipe at each location where the glovebag will
     be attached.  This serves two purposes.  First, it gives a good surface on which to
     seal the ends of the glovebag.  Second, it minimizes the  chance of releasing fibers
     when the tape at the ends of the glovebag is peeled off at the completion of the job.

 5.  Open the top  of the glovebag and cut down the sides to accommodate the size of the
     pipe (about two inches longer than the pipe diameter). Some bags have zippers or

   two-sided tape on top and straps at each end facilitating easier installation of the bag
   on the pipe.
6.  Place the  necessary tools into the  pouch located inside the glovebag.  This
    usually include the flexi-saw. utility knife, rags, scrub brush, wire cutters, tin snips and
    wettabte cloth. Cut out a donut shape with the inner diameter one-half inch smaller
    than the diameter of the pipe beneath the insulation. The outer diameter of the donut
    should be three Inches  longer than  the diameter of the pipe  insulation  being
    removed.  Finally, cut a slit in each of the two donuts so they can be slipped around
    the pipe. (Putting the wettable cloth in a small air-tight ziploc bag may make it easier
    to handle.)

7.  Place one  strip of duct tape along the  edge of the open top sJrt of the glovebag for
    reinforcement.

8.  Place the  glovebag around the section  of pipe to be  worked on.  If the bag  has
    double sided tape at the top, a preliminary seal can be made at this point. Next, fold
    the flap  back and tape it down with a strip of duct tape.  This should provide an
    adequate seal along the top. Next, duct tape the ends of the glovebag to the pipe
    itself, previously covered with plastic or duct tape.

9.  Using the smoke tube and aspirator bulb, place the tube into the water porthole (two-
    inch opening to glovebag).  By squeezing the bulb, fill the bag with visible smoke.
    Remove the smoke tube and twist the water porthole dosed.  While  holding the water
    porthole tightly, gently squeeze the  glovebag and look  for smoke  leaking  out,

     especially at the top and ends of the glovebag.  tf leaks are found, they should be
     taped closed using duct tape and the bag should be retested with smoke.

10.  Insert the wand from the water sprayer through the water porthole. Using dud tape.
     tape the water porthole tightly around the wand to prevent air leakage.

11.  One person places his hands into the long-sleeved gloves while the second person

12.  If the section of pipe is covered with an  aluminum jacket this is removed first using
     the wire cutters to cut any bands and the tin snips to remove the aluminum.  It is
     important to fold the sharp edges In to prevent cutting the bag when it is placed in the
     bottom. Use caution to prevent cuts - these edges are sharp!

13.  With the insulation  exposed, use the ftexi-saw to cut the insulation at each end of the
     section to be removed inside the glovebag.  (Note:  A ftexi-saw is a serrated heavy-
     gauge wire with ring-type handles at each end.)  Throughout this process, water is
     sprayed on the cutting area to keep dust to a minimum.

14.  Once the ends are cut, the section of insulation should be slit from end to end using
     the utility knife.   The cut should be made along the top of  the pipe  and water
     continuously supplied.  Again, care  should  be taken  when using the knife  not to
     puncture the bag.  Some insulation may have wire to be clipped as well.

15.  Spray all tools with water Inside the bag and place back into pouch.

     bag.

17.  Using the scrub brush, rags and water, scrub and wipe down the exposed pipe inside
     the glovebag.  (Note: Inexpensive horse rub-down mittens work well for this.)

18.  Wet the donut-shaped pieces of wettabJe doth over the exposed ends of insulation
     remaining on the pipe. WettabJe doth is a plaster impregnated fiberglass webbing
     available at many hardware and/or plumbing supply stores.

19.  Remove the water wand from the water porthole and attach the small nozzle from the
     HEPA-flltered vacuum.  Turn on the vacuum only briefly to colapse the bag.

20.  Remove  the vacuum nozzle and twist the water porthole dosed and seal with duct
     tape.

21.  From  outside the bag, pull the tools through the glove and away from the bag and
     twist it to separate it from the bag. Place duct tape over the twisted portion and then
     cut the glove from the glovebag, cutting through the twisted/taped section.  In this
     manner, the contaminated tools may be placed directly into the next glovebag without
     cleaning.  Alternatively, the glove with the tools can be placed in a bucket of water,
     opened underwater, and the tools cleaned and dried without releasing asbestos into
     the air.  (Note:  Rags and the scrub brush cannot be deaned in this manner and
     should be discarded with the asbestos waste.)

 INTRODUCTION

 While OSHA regulations allow  a respiratory protection program based on workplace
 conditions, EPA and NIOSH have published recommendations that breathing air systems
 be used to provide the "maximum feasible level" of respiratory protection for workers that
 are occupatlonally exposed to airborne asbestos fibers. The higher level of protection
 offered by breathing air systems such as Type C pressure demand supplied air respirators
 make them attractive for some asbestos removal projects.  Before providing breathing air
 on an asbestos removal project, it is important to understand some basic requirements.  A
 breathing air system should provide the following:

      •  A continuous sufficient supply  of quality breathing air,
      •  Adequate reserve or escape time,
      •  Breathing air temperature control,
      •  A continuous carbon monoxide (CO)  monitor  and alarm

This section  provides a review of breathing air systems including  a discussion of
theoretical and practical  issues relating to air compression, purification and distribution.
This information tends to  be technical in nature and is primarily provided as a reference or
resource to project designers.

CONTINUOUS SUFFICIENT SUPPLY OF QUALITY BREATHING AIR

A continuous sufficient supply of quality breathing air means the air pressure, volume and
quality requirements necessary for proper respirator operation  are supplied directly to
each respirator. The minimum OSHA requirement for quality breathing air is air that meets
at least Grade D  criteria established by the Compressed  Gas Association, Inc. (CGA).
Grade D air is a  minimum standard; other guidelines exist which are more stringent
Producing  and supplying breathing  air is accomplished by the combined effect of
compression, purification, and distribution processes. Persons interested in the operation
of any breathing air system for use with supplied air respirators should be familiar with the
principles of air compression.

Compression - Consider the theoretical  compression process apart from the mechanical
influence of compressors.  Atmospheric air carries water vapor and contaminants. In
atmospheric air, water vapor is not usually considered a contaminant  In compressed air
for breathing purposes, however, water vapor should be considered a major contaminant
which also  traps and carries other contaminants.  In order to produce breathable air,
water vapor must be  properly processed out of the  compressed air.

When a parcel of air is compressed, its volume decreases while its absolute pressure and
temperature increase (Figure C-1). Air temperature always  rises with compression. Even
at low pressures,  there  are substantial  temperature elevations.   The contaminants  and
water vapor are also compressed with their concentration increased.  Compressing air
also reduces its  ability to  hold water  vapor.  However, increasing  the  temperature
Increases the ability to hold water vapor.  Because of these  two opposite effects, water

vapor will not condense immediately upon compression, but most certainly will condense
as the air temperature decreases.

When  a parcel of compressed air is held for a  time at its higher pressure, the heat
eventually dissipates. Once compressed air has cooled back to ambient temperature, a
large amount of the water will have condensed. Condensed water can be mechanically
collected and drained.  Any further reduction in temperature of the air parcel will result in
additional water condensation.

Mechanical compression requires a compressor of some type.  Additional heat from the
drive motor and friction will be added to the air during the compression process. The
compressor may  also add wear particles such as metal, carbon, etc.  In addition, the
compressor may also add lubricant oil as either liquid oil or oil vapor. If the compressor
operates at excessive temperatures, it may actually form carbon monoxide (CO) within the
machine, although such CO formation Is rare.

The  use of a compressor may be  limited to  purposes for which it was originally designed
and  buW.  For instance, a compressor built to power other industrial air machines may not
need heat, water, and oil removal.  In fact, some compressors actually have "oilers' in the
output air to increase the oil being carried in the  air.  An  unsuitable compressor for
breathing air could easily overpower the finest air purifier assembly resulting in excessive
costs to maintain the required air quality.

The  real effect of water as a contaminant of  breathing air can be understood by tracing Its
pathways through a mechanical compressor.  The machine will draw outside air with water
vapor through a remote intake pipe to the compressor. If the machine is properly designed

                                                          Append* C - Breattvng AJr Syclarm
 for breathing air applications. It will have an aftercooter to cool trie compressed air and to
 condense most of this water. The water can be mechanically removed from the aftercoder
 using a drain trap. This leaves some water vapor still in the compressed air.  Most of the
 water vapor will be removed along with any other contaminants by the air purifier assembly
 that is downstream of the compressor.

 Purification - Ordinary compressed air cannot  be used to supply breathing air to work
 crews working  in  hazardous atmospheres.  Ambient breathing air, when pumped
 through an ordinary compressor,  Is not fit (or human respiration.  Even if the
 compressed air is filtered to remove dust and other participates, it still contains the
 contaminants in  ordinary atmospheric  air plus the localized contaminants near the
 compressor intake, plus any contaminants (oil  vapor) and wear particles added during
 compression.

 The compressor intake is especially vulnerable to all types of carbon monoxide sources.
 Sources of CO, such  as transient motor vehicles and other mobile internal combustion
 engines, are especially hard to control on the  typical asbestos abatement job.  These
 contaminants are concentrated by the compression process.   For these reasons,
 compressor-based breathing  air systems  will not provide protection unless the air Is
 purified.

 Purification  of air is  a precise technology which has developed over many years.
 Purification is considerably more than filtration.  Filtration is simply capture and removal of
particulars by a fitter and is a small part of the overall purifying process.

Purifiers are based primarily on the design and use of adsorption.  Adsorption of vapor and
chemical contaminants is done by proper design and use of the class of materials known
as adsorbents.  The common adsorbents used in the design of air purifier assemblies
may include molecular sieves, silica gel, activated alumina, and activated charcoal.

Adsorption is the adhesion in a thin layer of molecules to the surface of solids or liquids
with which they are in contact. Adsorbents are porous-type materials with large quantities
of interconnected, submicroscopic internal voids, pores, or capiBaries. This internal porous
structure gives these adsorbent materials very large  surface areas  in contact  with the
gases to which the adsorbent is exposed.  These adsorbents can hold onto, or adsorb onto
their active surfaces, selected contaminants. These adsorbents are not all equally effective
with all contaminants. Furthermore, water can decrease the efficiency of many adsorbents,
making  them ineffective in removing the intended contaminants. For the adsorbent design
to be effective, the appropriate types,  quantities, and sequence of adsorbent materials
must be selected.

The effectiveness of all adsorbents increases with increasing pressure. As the pressure of
the air  increases, the density of the air increases.  More dense  air exposed to any
adsorbent material simply means that more of the air is pushed into more intimate contact
within the adsorbent.  Therefore, as air  pressure  Increases, less  adsorbent Is
needed to do the same job.

Adsorbents must be periodically replaced. Adsorbent  cartridges can  be equipped with a
color change reaction that will show the progress of adsorbent use.  Such cartridges can
be monitored based on color change through a dear canister.  Adsorption canisters may
also be  replaced on a simple operational time basis.

                                                                              Page?
 The carbon monoxide catalyst is used to eliminate carbon monoxide.  On  the catalyst
 surface, carbon monoxide, in concentration ranges of 10 ppm to 600 pom, is  brought into
 contact with oxygen in the air. The carbon monoxide is oxidized to carbon dioxide (COa)
 The end result is that dangerous CO is changed to CO?, which is not harmful  in these low
 concentrations.  Theoretically, catalysts  should last forever; but, in practice, they
 permanently  adsorb trace  chemicals  and become  "inactive."  Most manufacturers
 recommend yearly replacement of their catalyst-type filters.

 Even very small amounts of water vapor on the catalytic adsorbent 'poison'  the catalysl
 and reduce its activity. For such a catalyst to operate for a reasonable period of time, the
 air entering the catalyst must be very dry, below 5 percent relative humidity.

 The most effective way to dry air to these conditions is to use drying adsorbents before the
 air reaches the catalyst.  For pressures under 200 psi, the  heatless air regenerated dryer
 has  evolved as the simplest and most rugged method to continuously regenerate the
 required adsorbent material.   It consists of airline plumbing, two central air dryer towers,
 and  a tower switching system. In action, this system has one tower drying the airstream
 while the other tower is "off-cyde." Some of the dry air output of the operating tower is split
 off and sent in reverse  through the  'off-cycle' tower. Water  previously adsorbed is
 released and vented to tfie atmosphere.  In this way the off-cyde adsorbent material is
 renewed or regenerated.

A typical adsorbent design containing activated  alumina in each tower can usually operate
for several years before the activated alumina must be replaced. Replacement  of activated
alumina only one time every few years is inexpensive  when  compared to a  throwaway
canister design which would need new  activated alumina every eight hours.

Before compressed air reaches the alumina for water vapor removal, oil must first be
removed.  The active media in the oil adsorption prefilter  is chosen for its ability to
selectively retain oil and oil vapor.  It can be formulated with a color change reaction and
placed into a dear canister for visual determination of the filter media remaining.  The oil
vapor adsorption prefilter may quickly be saturated if "slugs' of  oil and water come from the
compressor.  Removal of liquid  'slugs' just prior to the oil prefilter is accomplished by a
coalescing filter and drain trap.

Grade D breathing  air Is specified by  OSHA  29 CFR 1910.134(d)(l) as  that
listed by  the  Compressed Gas  Association Specification  G-7.1.   Most
established  American manufacturers of  both high and  low pressure breathing air
purification  systems design and  test their systems to produce Grade 0 or better breathing
air.

Distribution - Breathing air  must be delivered  to the respirators  in a continuous and
sufficient supply.  This means that proper air pressure and air volume requirements must
be maintained through the purification and delivery processes.  Required air pressure can
be ensured:
       •  by measuring and controlling the air pressure within the air delivery system at
         the entrance to the respirator  hoses.

       •  by maintaining  the  required pressure under all flow conditions when  all the
         respirators are being used.

Two factors  which  affect  the respirator  pressure during air flow  are (1)  the
Inside diameters of hoses and  their connectors, and (2) the overall length of

 air supply hose.   In low pressure systems, respirator hose line pressures must typically
 be maintained in the 65-100 pounds per square inch gauge (psig) range.  OS HA and
 NIOSH prohibit the hose length from the respirator manifold to the worker to exceed 300
 feet.

 A test of the low pressure distribution system can be conducted by:  (1) laying out the
 required length of air transfer hoses; (2) connecting all respirator manifolds; (3) attaching
 the maximum number of respirator hoses and respirators to be used; (4) pressurizing the
 system; and (5) with  all respirators in use.  checking  the  pressure at  the respirator
 manifolds.

 Should the  pressure at the  manifolds be less  than the  required respirator pressure,
 increasing the pressure may be accomplished by using extra large diameter supply hoses.
 or increasing compressor pressure combined with  use of a control regulator at  the
 respirator manifolds. If the required respirator pressure cannot be maintained, the hose
 lengths should be shortened to increase pressure, or a larger capacity system used.

ADEQUATE RESERVE AIR OR ESCAPE TIME

Providing for adequate reserve air or escape time is a necessary function of the breathing
air system.  The OSHA respirator standard [29 CFR 1 91 0.1 34(d)(2)(ii)] states. 'A receiver of
sufficient capacity  to enable the respirator wearer to escape  from a  contaminated
atmosphere  in event of compressor failure and alarms to indicate compressor failure shall
be Installed in the system.*

                                                          App«ndU C - BoNtfvng A* Systems
This poses the question of how much reserve time, and therefore how much stored air. is
necessary. If a work crew were told an escape test is going to be conducted at a specified
time, such a test might show that only 10 to 20 minutes were required. The escape time
required under actual workplace conditions could be considerably longer.  Complex airline
routing and tangling, work on scaffolding or in restricted access areas, and the work crew
shower requirements can all lengthen escape time. For a crew size of 10 workers, actual
egress times have been measured at 30 to 50 minutes and more.  Therefore, for most
asbestos projects, a reserve time specification of  50 minutes to 1 hour is needed. Certain
special asbestos jobs with  more complicated egress conditions may need escape time of
more than one hour.

Breathing air stored in pressurized cylinders is used as the method to obtain the required
escape time.  Using  high pressure  (2000 to 4000 psl) reserve air storage does not
adversely affect specification, choice, or the use of low pressure breathing air systems.
The cost of providing a  high pressure standby reserve system with a  low  pressure
breathing air system is minimal. Rental is the normal arrangement for suppliers of such
high pressure tanks. Since this reserve should be used only for the occasional emergency
compressor stoppage,  the actual cost of the  air used on a job site should also be minimal.

 therefore reducing the transfer of heat from the body.

 In the typical asbestos work site, cool breathing air will aid in cooling the asbestos worker.
 The lung serves as a source of heat transfer.  Cooling  methods using cool breathing air
 can also be used to provide cool air externally to the worker.  This can be accomplished
 simply by directing the cool exhaust from the respirator exhalation valve down inside the
 asbestos worker's protective clothing.  Three common methods are available to cool the
 breathing air.  These are the aftercooter, a vortex tube, and adiabatic cooling.

 Aftercooler - Hot compressed air exiting a compressor may be cooled by an aftercooler or
 heat exchanger.  These heat exchangers may transfer the heat either to the ambient air (air
 cooled) or to locally available cold  water  (water cooled}.  For the downstream air purifier
 assembly to function properly and give good control to process high-quality breathing  air.
 excess heat, water, and oil must be removed. This is accomplished by first removing heat
 and then removing the condensed water and oil.

 The efficiency of the air cooled aftercooler wil be affected by the ambient air temperature.
 Because of this fact, the air cooled aftercooler will not function as efficiently on the hottest
 days, when worker cooling is most needed.  Therefore, the best type of aftercooler choice
 to ensure that  worker  cooling is  available when needed  may  be the water cooled
 aftercooler.

 Vortex Tube - The vortex tube (for cooling or heating) is another available method of
worker temperature control. The vortex tube is simple, lightweight and inexpensive.  It is a
tube of approximately one-half to one inch  diameter and six to twelve inches in length. Air

is admitted into ttie side of the tube and split into two separate airstreams, each exiting at
opposite ends of the tube.  One airstream is hot, the other is cold.  Either of these two
airstreams may be directed  into the worker's disposable suit or  hood to provide external
temperature control to the worker.

The disadvantage of the vortex tube is that it uses a comparatively high volume of air,
approximately 15 to 20 cfm per worker.  Compared to the air used by a pressure demand
type respirator, each vortex tube will use as much air as would  be needed to supply four or
five pressure demand respirators.  Therefore, the use of vortex tube cooling will require
increased capacity for both the compressor and the breathing air purifier.

Adiabatic Cooling - Adiabatic cooling is available when sufficient cooling capacity has
been designed into each of the multistage compression steps found internally in a high
pressure compressor.  Provided  that the  high pressure compressor cooling design is
adequate,  cool  or ambient temperature  air  will be produced  at  the  high pressure
compressor outlet This air is delivered to the air reserve tanks and then into the asbestos
work area  via high pressure airlines at a pressure of 1000 to  4000 psig.  A regulated
control panel in the work area drops the high pressure air down to the required respirator
line  pressure (typically  in  the 65 to  100 psig  range).  The  air temperature drops
dramaticaMy with this rapid air expansion at the control panel and  the resulting cotd air is
directed into the  respirator lines.  Adiabatic  cooling in this  manner is very  simple,
lightweight and  reliable,  provided the  compressor  has been  initially designed to  be
adequate for such cooling.

 CONTINUOUS CARBON MONOXIDE (CO) MONITOR AND ALARM

 Providing a continuous CO monitor and alarm  is a good practice.  The  CO monitor
 should be specified  as a part of the overall breathing  system or breathing
 air purifier assembly.  The CO monitor must be kept in calibration and the alarm tested
 daily.

 f.ow Pressure Breathing Air System Alarm Response - When the alarm sounds, the
 breathing  air system should immediately be switched to the high pressure standby air
 reserve system.  Depending on the capacity of the reserve system, the workers should exit
 the work area. The outside supervisor should check off all workers as they leave the work
 area to make certain that all workers have exited the work area.  With sufficient high
 pressure reserve or when using a high pressure breathing air system with sufficient in-line
 reserve capacity, CO alarms and  unexpected  compressor shutdown may be handled
 without disruption in the asbestos removal work.

 Remember, air being processed in a low pressure air system is  almost immediately being
 delivered to and breathed by the workers. Therefore, when using the low pressure system,
 there is an immediate need for switch over to the high pressure reserve air when the CO
 alarm sounds. If only the minimum high pressure reserve is available, the workers should
 exit the area. If additional  reserve air capacity is available, the  workers should exit when
 the reserve supply approaches the minimum acceptable amount.

 High Pressure Breathing Air System Alarm Response - Immediately stop the air flow from
the compressor into the in-line reserve air bank by shutting the output air valve. (Note: If so
arranged, this step may be automatically accomplished through relays in the  CO monitor.)

Low Pressure Breathing Air Compressor - The tow pressure breathing air compressor
produces pressures between 100 and 200 psi. It has sufficient flow capacity to provide the
flow needed for the respirators being used. The compressor should also be equipped with
sufficient interstage and aftercooling capacity to reduce the air temperature to within 10°F
of the ambient air temperature.  The low pressure compressor should be equipped with
suitable moisture removal traps to be able to  remove 60 to 85 percent of the water/oil
condensed within the machine.  Water removal may be either automatic and continuous or
manual and periodic.

Aflercoolsr Assembly  with  Water Removal Trap*:— Tha after cooler assembly  is used
immediately following the tow pressure breathing air compressor.  The aftercooler and its
water trap may be incorporated physically in the compressor.  The purpose of the
aftercooler assembly is to assure that the air temperature is reduced to  within  10°F of
ambient air temperature.  Such a reduction in temperature forces condensation of water/oil
in the airstream. The cyclone-type water separator or water trap is also a part of the
aftercooler.  This separator or water trap is used to allow removal of the water/oil mixtures
condensed by the action of  the aftercooler in tne airstream.  Aftercoolers  may either be
ambient air cooled or water cooled.

Air Purifier Assembly - The purpose of the purifier network is to purify the  air to at least
the required Grade D  air quality.  A diagram is  provided in Figure  C-3.   A detailed
discussion of its operation was provided previously in this section.

Standby High Pressure Reserve System - The only effective method to store sufficient air
for an industrial sized asbestos removal work crew is through the use of high pressure
storage tanks.  Such tanks are available for rental at low rates, and they can be delivered
directly to the asbestos abatement work site.

Surge Tank or In-Kne Air Volume Tank - A surge tank provides air storage capacity so that
short-term peak flow conditions will not deplete the air supply.

Distribution Hose and Manifold with Connections for Respirator Hoss  Lines - Once air is
processed through the low pressure air purifier It Is directed Into the delivery airline and is
Immediately available to the worker.

THE HIGH PRESSURE SYSTEM

The high pressure breathing air system  shown in Figure C-4 is composed of four major
components:
       • A high pressure compressor,
       • An air  purifier assembly,
       • A high pressure air storage  bank
       • A high pressure control and distribution panel.

Hioh Pressure Compressor-The function of the high pressure compressor is the same as
that in the  low pressure  system.  The  low  pressure  compressor utilized one or two
successive compression steps or stages to compress the air up to 100 to 200 psi. The high
pressure machine pumps the air to pressures of 2000 to 4000 psi utilizing from three to five
successive stages of compression.

Each time the air is processed through a compression stage, its density and its pressure
are increased, and its volume is decreased.  The air temperature increases sharply
through each compression stage due to the adiabatic process.  Following each stage of
compression, the air is put through an intercooler that transfers considerable heat out of
the air.  Once the compressed air temperature is brought down, it cannot hold the moisture
that it carried  before that stage of compression, and the water vapor and other vapors
condense.  Following each intercooler stage is a cyclone-type liquid trap.  The liquid trap is
a vertical cylinder with a drain valve in the bottom.  The air is introduced tangentially near
the top of the trap, and creates a spinning vortex within  the trap.  The higher density
condensed liquids are thrown against the cylinder walls of the trap.  They drain down
along the walls of the trap and can be removed from the compressor through the drain
valve in the bottom.  Even though water has been condensed and removed, the air is
saturated In this state, further compression or cooling will remove additional water.

The air from the preceding compressor stage is now carried into the intake of the next
compressor state. Here K is again compressed, cooled, and water is again extracted. This
process of  compression,  cooling,  and  condensate  removal is repeated  for every
succeeding state within the high pressure compressor.  High pressure makes it possible to
take out considerably more heat and moisture from the air than could be extracted by low
pressure compressors.

These methods do  not require replacement adsorbent cartridges nor the maintenance
associated with such cartridge changes.  Another result of such processing is to reduce the
water vapor and  other contaminants that must be removed by the adsorbent purifier.
Therefore,  one  of the  major  effects  of  high pressure mechanical processing

 In  the breathing  air compressor Is to reduce the required size and  weight  of
 adsorbent material needed  In  the  high  pressure purifier assembly.

 Air Purifier Assembly - The high pressure purifier assembly (Figure C-5) fe made up of an
 aftercooler, a combination coalescing filter/drain trap, and a number of successive purifier
 containers that hold adsorbent materials.

 The function of  the aftercooler is similar to that of the intercoolers.   Following the
 aftercooler, the air is put through a  combination mechanical coalescing filter element/drain
 trap.  Vapor is not removed in mechanical drain traps.  There are some  very tiny drops of
 condensed materials, called aerosols (water, ofl, etc.) which act almost like vapor and also
 move through ordinary drain traps.   In order to mechanically remove these aerosols, they
 are forced, in the  coalescing element, to impact or squeeze  together and to form big drops
 out of the aerosols.  These coalesced liquid drops can now be drained from the airstream.

 The air now moves into the adsorbent  section of the purifier.  Adsorbent materials to be
 used in high pressure adsorbent chambers are the same as used in low pressure designs:
 molecular sieves,  silica gel, activated alumina, and activated charcoal.

 Following the coalescing filter trap, there are usually  two  to four successive additional
disposable adsorbent containers. These are  usually replaced on  a  machine time  basis,
but color change  or other indicators are available.  Since  cartridges cannot regenerate
themselves, it is especially important that they are changed on a scheduled basis. Failure
to do so could allow adsorbents to reach saturation and permit contaminants to enter and
contaminate the high pressure air storage bank.

 Continuous CO Monitor and Alarm - Air passing from high pressure purifier should be
 continuously monitored by an electric carbon monoxide alarm. Should carbon monoxide
 be produced  in the compressor or induced into the compressor air  intake,  it will be
 detected by the CO monitor. The CO alarm will visually and/or audibly warn if the CO level
 goes above the  required level.  Visual warning Is accomplished  by  meter and by a
 green/red system of lights.  High decibel audible alarms are also available.

 High Pressure In-line Air Storage  Bank - High-quality  air.  Grade D or better, is now
 pumped directly into the high pressure storage bank. The function of this  high pressure
 storage bank is to act as an air reservoir, so that:

       • The peak air flow demands can be met without concern for or  limitation by the
        maximum compressor output.

       • The compressor and purifier can be sized for lower flow rates than the peak flow
        rates required.

       • A greater capacity (typically three to six hours) than the minimum required for
        escape (typically one hour)  can  be used to allow  routine or emergency
        maintenance of the system to be accomplished without interrupting the work crew.

High Pressure Control and Distribution Panel -Air is delivered into the work area from the
high pressure air storage bank through high pressure lines.  These lines can be flexible or
rigid and may be  several hundred feet  in length. This high pressure line is led into the
building to a distribution panel.  The panel has a high pressure gauge that may be marked
off in pressure units or it may be rated in time units (hours) for any size work crew.  Each

worker with a respirator attached to the panel can at all times see exactly how much
working reserve time (and escape time) is available.

As with the low pressure breathing air system manifold, this panel also contains a regulator
and low pressure gauge.   The panel reduces the pressure of  the air to the pressure
suitable for the respirators in use. Low pressure respirator hose line lengths are limited to
not more than 300 feet by OSHA from this panel.

COMMON PROBLEMS WITH BREATHING AIR SYSTEMS

To properly design  and specify breathing  air systems it  is important to  anticipate and
eliminate potential problems before they arise during an asbestos removal project. At a
minimum, understanding common problems  associated with breathing air systems can
prepare the designer to consider precautions which will minimize worker health and safety
risks.  The most common of these problems generally effects either the quafty or sufficient
supply of air.

The problems associated with poor-quality air occur during the air intake, compression and
filtration stages.  While the breathing air system is designed to purify the air prior to
delivery, it  is essential that  ambient air near the intake be as pure as possible.  If an
Intake Is located  near a  source of carbon monoxide (CO) It can contaminate
the air supplied to respirators. Intake lines should be located away from the exhaust
of gasoline  or diesel compressors. Automobfle exhaust is another source of CO which can
be avoided by placing the  inlet away from exhaust streams.  The possibility of CO
problems is also controlled by a property functioning CO monitor.

 Another problem with intake air occurs when air is drawn from a confined space or other
 area which may be oxygen deficient.  The breathing air system will not improve the oxygen
 concentration of the ambient air.  Precautions should also be taken to assure that the
 intake air is not contaminated by asbestos fibers.

 Other air quality problems are introduced during the compression stage.  Oil can be
 introduced by malfunctioning or improperly designed systems.  The presence of oil in the
 air supply is commonly characterized by an oily scent or taste.  Breathing oil-contaminated
 air can lead to serious health problems such as lipoid pneumonia.

 The purification stages can also be a source of breathing air system problems. Excessive
 moisture levels can reduce the effectiveness of the adsorbents and deliver moisture-laden
 air that can fog the inside of respirators' face plates. A common  problem is a lack of
 adsorbents or inadequate adsorbents.

 Another air-quality problem results when the air supply is too hot for the job.  Many
 asbestos abatement projects use breathing air systems as a source  of cooling for workers
 in hot environments.  When the supply air is too hot it does not provide adequate cooling
 for the workers, which can lead to heat stress.  In mild cases, heat stress can lead to
 exhaustion and dizziness. This is particularly problematic for workers working on or near
 scaffolding or those in the vicinity of bum or shock hazards. In extreme cases, heat stress
 is a severe health hazard which can cause loss of consciousness or even death.

 Besides providing adequate quality  of air. breathing  air systems  must also provide  a
continuously  sufficient  volume  and  pressure  of air.  The  most common problems

associated with insufficient air supply to respirators involve the lack of adequate air supply
pressure, respirator damage or selecting the wrong respirator.

Malfunctions of the breathing air system can occur when the air supply is not  under
enough pressure when  h Is supplied to the respirator.  The cause  of the problem can
sometimes be traced to an over-extended low pressure supply line that is longer than 300
feet.  Another possibility is  that not  enough air is flowing from the compressor to satisfy
peak flow demands, such as when the entire crew breath intake  coincides.  The system
must be able to supply at least 4 cfm per person to meet  peak  flow demands.  A
malfunctioning or poorly-designed filtration system can also cause a drop in pressure. The
same is true for high pressure systems with an  improperly adjusted regulator or with
inadequate flow.

The ability of a system to deliver sufficient air supply can also be affected by a damaged
respirator.  Damage to the  exhaust  valve can restrict the air flow or cause leaks during
exhaling.  Regulator damage can cause the free flow of excess air. These problems can
be avoided through regular inspection of respirator use in the work area during abatement.
During these  inspections, the inspector should listen  for constant  flow, watch system
pressure and be on the lookout for excessive pressure drops.

A serious  malfunction of the compressor or no reserve  or inadequate reserve air supply
can lead to a total cutoff of air supply. It should be noted that some air reserves are not fail
safe. Some require electrical power  to operate. Additional problems occur when the tank
valves are left dosed  or the tanks are empty.  Proper attention to inspection and safety
checklists  can reduce the likelihood of such an event
