Dear School Officials:
Until recently exposure to asbestos was generally
considered an occupational health hazard for asbestos
workers. However, now we have learned of an equally
serious exposure problem that can occur in all types of
buildings in which certain asbestos-containing materials
have been used for fireproofing, insulation, and
decoration. Asbestos can be released from these materials
and contaminate the building environment. Individuals who
are then exposed to the asbestos could develop lung cancer
or cancers of other parts of the body. Unfortunately,
detection of asbestos-related diseases is difficult since
the latency period between exposure and appearance of the
disease is sometimes as many as 20 to 40 years.
Since these materials are found in school buildings, we at
EPA are particularly concerned with the exposure of school
children. EPA has worked with the States to develop a
program that responds to the need for accurate information
and guidance to deal with this difficult problem. The
enclosed manuals are a major part of this program and are
being mailed to all public school districts. They were
prepared to inform you of the health hazards associated
with asbestos and outline the steps you and the schools in
your district can take to identify asbestos-containing
materials and to protect students and school personnel
from exposure.
-------
Also participating in this EPA program are the Department
of Health, Education, and Welfare, the Occupational Safety
and Health Administration, and the Consumer Product Safety
Commission. Through the Regional Offices located in major
cities across the country, EPA and these Agencies will
provide assistance for the difficulties that you may
encounter in undertaking a control program in your
schools. We are operating several toll-free numbers that
you can call to ask for information and assistance. A
videotape that was prepared to supplement this manual will
also be available for your use.
A survey form is included in this manual. The form asks
questions on the results of the control programs you
conduct in your schools. Your participation in this part
of the EPA program would be appreciated. By completing
the form you will assist us in assessing the extent of the
asbestos-containing material problem in the United States.
I encourage you and your staff to review the enclosed
manuals and inform the schools in your district of the EPA
program. A successful nationwide school asbestos program
depends on your efforts and those of school officials
across the country. We look forward to working with you
in the important weeks and months ahead.
Sincerely,
Assistant Administrator
for Toxic Substances

Preface
Recently there has been an increasing awareness of the
significance of environmental factors in causing illness.
The fibrous minerals known as asbestos, used in many
different kinds of products and applications, have
entered the environment in both occupational and non-
occupational settings. The lung disease, asbestosis, and
some cancers of the lung, abdomen, and other parts of
the body have been clearly related to asbestos
exposure.
The Environmental Protection Agency (EPA) is
concerned with the disease-causing potential of
intermittent, low-level exposures that can occur in some
school buildings from certain asbestos-containing
materials. EPA has established a guidance program to
inform States and local school officials of the possible
health hazards associated with asbestos. EPA will
provide guidance to schools which undertake programs
to identify and control exposure to these asbestos-
containing materials. Although the EPA program is
specifically directed to schools, information and
assistance will also be available to contractors, workers,
and any individuals who are concerned about exposure
to asbestos in buildings.
EPA's guidance package contains two parts. This
manual, which is Part 1 of the package, is written for
school officials. Part 1 outlines steps that schools can
take to conduct an asbestos control program. Part 2
contains more detailed information on asbestos
identification and control methods. Part 2 will be
particularly useful to school personnel, contractors, and
others involved in actual asbestos inspection and control
activities.
As the lead Agency for the school asbestos program,
EPA will provide additional information and assistance
to the States and school districts through the Agency's
ten Regional Offices located throughout the country.
Each Regional Office will have a Regional Asbestos
Coordinator who will work with the States to assist in
undertaking asbestos control programs.
Other Federal Agencies concerned with the asbestos
problem will also participate in the program. The
Occupational Safety and Health Administration
(OSHA) and the Department of Health, Education,
and Welfare through the National Institute for
Occupational Safety and Health (NIOSH) and the
Public Health Service will provide assistance particularly
in the areas of occupational safety and health. This
assistance will be made available through these
Agencies' Regional Offices.
Questions about the information in these manuals or
about the EPA school asbestos program should be
referred to the EPA Regional Asbestos Coordinators
listed on page 33.

A Close-up of a Type of Asbestos-Containing Material That Can Be Found in School Buildings
-------
Chapter 1: Introduction: The Concern
Exposure to asbestos was initially associated with a
chronic and debilitating lung disease called asbestosis.
More recently exposure to asbestos has been associated
with lung cancer, a rare cancer of the chest and
abdominal lining called mesothelioma, and cancers of
the esophagus, stomach, colon, and other organs.
Asbestos also acts as a potent cancer-causing agent in
combination with cigarette smoking. In all asbestos-
related diseases there is a latency or induction period of
many years between initial exposure and appearance of
the disease.
In most cases asbestosis has followed long exposure
to high levels of asbestos fibers. Therefore, asbestosis is
not as significant a concern in schools as cancer risk.
The potential for increasing cancer risk may exist at
much lower and shorter exposures than those for
asbestosis.
Under certain conditions, exposure to fibers released
from asbestos-containing materials in buildings can
reach levels considered potentially hazardous. Some
asbestos levels measured in school buildings have even
been shown to briefly exceed the current Federal
workplace exposure level standards.
Why is there so much concern now?
EPA is concerned in view of the increasing knowledge
of the potential of asbestos as a cancer-inducing agent
at low-level exposures and the asbestos contamination
that has been found in some schools. Another very
important concern is that cigarette smoking can
enhance the disease potential of asbestos exposure.
Is there a safe level of exposure?
EPA and the scientific community believe that any
exposure to asbestos involves some health risk. No safe
level of exposure (or threshold exposure level) has been
established. Further, it is impossible at this time to
confidently estimate the exact degree of risk associated
with low-level exposures.
What is considered the best or safest approach to
asbestos exposure?
Where possible all exposure to asbestos should be
eliminated or controlled.
Are there special concerns about asbestos in schools?
The school children population differs from other non-
occupational populations in age, population density,
and behavior.
The exposure of children and adolescents to asbestos
in the school building occurs early in their life span.
Their remaining life expectancy provides a long
development period for asbestos-related diseases.
A large number of students can be exposed at one
time to asbestos that is released from asbestos-
containing, materials present in the school building. The
duration of exposure is of concern since school children
attend school daily for most of the year.
The school population is very active. Certain
asbestos-containing materials can be damaged during
school activities and as a result of the capricious
behavior of students. When the material is damaged,
asbestos fibers are released and exposure can occur.
Many cases of badly damaged asbestos-containing
materials have been found in schools.
Are there any Federal laws or regulations that protect
school children from asbestos exposure in school
buildings?
There are currently no Federal laws or regulations that
protect children in school buildings where asbestos-
containing materials are already present.
Is a medical examination necessary for persons exposed
to asbestos in school buildings?
Medical examinations are not recommended in school
exposure situations. It is difficult to detect asbestos-
related diseases in children due to the long induction
period before the disease appears. Individuals who have
been exposed to asbestos should avoid smoking; and. of
course, medical advice should be obtained for any
specific concerns or symptoms.

Chapter 2: Asbestos and Its Uses
What is asbestos?
Asbestos is a term for a group of naturally occurring
minerals that separate into fibers. The mineral rock is
mined and then milled for commercial use. Asbestos
fibers are incombustible and have good thermal and
electrical insulating properties. There are six asbestos
minerals that are used commercially:
Chrysotile
Amosite (Cummingtonite-grunerite asbestos)
Crocidolite
Anthophyllite asbestos
Tremolite asbestos
Actinolite asbestos
Chrysotile and amosite are the most frequently found
asbestos minerals in the asbestos-containing materials
used in school buildings.
Why is asbestos a unique environmental contaminant?
The durability of asbestos fibers and their small size
and fibrous shape make asbestos an unusual
environmental contaminant.
Asbestos fibers cannot be easily destroyed or
degraded. The size and shape of these fibers permit
them to remain airborne for long periods of time.
Asbestos fibers that are released from asbestos-
containing materials enter the air and contaminate the
building environment.
When the fibers have entered the air, individuals in
the building can be exposed and inhale the fibers.
Although most fibers will not remain in the lungs, those
that are retained will stay indefinitely.
What are some uses of asbestos in school buildings?
Most asbestos products are used in building
construction and many products containing asbestos are
found in buildings. Asbestos has been used in cement
products, plaster, fireproof textiles, vinyl floor tiles,
thermal and acoustical insulation, and sprayed
materials.
Asbestos also is used in automotive brake linings. In
schools that have shops for automotive training,
asbestos contamination can occur as a result of
automotive brake servicing.
For more information on the uses of asbestos, see
pages 1-1-1 and 1-1-3 of Part 2.
What asbestos-containing materials in school buildings
can create an exposure problem?
Only certain kinds of asbestos-containing materials in
school buildings are considered hazardous. The
potential for release, contamination, and exposure
depends on the condition of the asbestos-containing
material (such as deterioration from age) and the
probability that the material will be damaged.
Hard asbestos-containing materials such as vinyl floor
tile do not generally create exposure problems.
Asbestos fibers are firmly bound or encased in the
material. Sanding, grinding, or cutting will cause
Raw Chrysotile Showing Fiber Structure

-------
asbestos fibers to be released. Therefore, these hard
materials should not be considered hazardous unless
they are machined.
Soft or loosely bound (i.e., friable) asbestos-
containing materials can release asbestos fibers
following only minor disturbance to the material. It is
these soft asbestos-containing materials that can cause
contamination and exposure problems.
What is friable material?
Friable material is material that can be crumbled,
pulverized, or reduced to powder in the hand. Friable
material may be an asbestos-containing material or it
may be a material that contains other fibers such as
cellulose and glass fibers.
This manual is primarily concerned with identifying
friable asbestos-containing materials in school buildings
and recommending steps to reduce the exposure that they
may cause.
What are friable asbestos-containing materials?
Friable asbestos-containing materials are materials that
were used for fireproofing, thermal and acoustical
insulation, or decoration in building construction and
renovation. The asbestos content of these materials is
usually found in the range of 5% to 50%. These
materials were usually applied by spraying but have also
been applied by troweling. They are friable in varying
degrees depending on the components of the material,
the amount of cement added, and the method of
application. Sprayed material is usually soft.
Cementitious material varies from soft to relatively
hard.
Throughout this manual, both cementitious and
sprayed asbestos-containing materials will be called
asbestos materials.
What is sprayed asbestos material?
Sprayed asbestos material is a mixture of asbestos
fibers, other fibers (cellulose, non-asbestos mineral
Friable Material That Has Been Scraped
fibers) and a binder which has been applied to ceilings,
beams, and other surfaces by spraying. It has been
widely used for fireproofing, thermal and acoustical
insulation, and decoration. Most friable material in
schools is sprayed material.
In 1973 EPA prohibited the spraying of asbestos
material for fireproofing and insulation. EPA
prohibited the application of sprayed asbestos material
for nearly all purposes in 1978.
Where are friable asbestos materials located?
Friable asbestos materials are usually found on
overhead surfaces, steel beams, ceilings, and
occasionally on walls and pipes.
Does all friable material contain asbestos?
Many materials that look like friable asbestos material
do not necessarily contain asbestos. Some friable
material contains glass fibers, cellulose, or other non-
asbestos fibers.
How are asbestos Fibers released from friable asbestos
material?
Fibers are released from friable material as a result of a
breakdown in the integrity of the material due to
deterioration or direct contact and damage.
As friable asbestos material ages, it can lose its
cohesive strength and release fibers. Fallout of fibers
from deteriorated material is usually low-level but
continuous.
Fiber release by contact and damage depends on the
accessibility of the material and the degree of
disturbance. Contamination can be very high for brief
periods of time during a disturbance and then gradually
decrease as the fibers settle. Fiber release can occur

-------
after only minor contact with friable material.
Direct contact or damage to asbestos materials can
occur in a number of ways:
• School Activities—A ball hitting friable material on
a gymnasium ceiling or wall. Hanging pictures or
attaching displays to friable material will cause fiber
release.
• Maintenance Activities—Any maintenance activity
involving intentional or accidental contact with friable
material.
• Vandalism—Material may be scraped, gouged, or
hit.
• Water Damage—Water from roof or plumbing
leaks will cause material deterioration and in some
cases delamination (i.e., breaking away of layers of
material from the underlying surface).
• Vibration—Building vibration from sources within
or outside the building. For example, vibration from
activities on the floor above or vibration from
machinery can cause movement of the friable material
and release fibers.
Fibers that have been released can remain suspended
in the air for many hours. After the fibers settle, they
can be resuspended in the air by disturbances created
by student activities or custodial work such as dusting
or sweeping. Resuspension of asbestos fibers in the air
is called reentrainment. Reentrainment may cause
repeated exposures after the fibers are released from
the friable asbestos material.
For more information on asbestos contamination, see
pages 1-2-3 to 1-2-11 of Part 2.
Is asbestos contamination permanent once it occurs?
Asbestos fibers tend to remain in the building that they
contaminate but can be removed by cleaning. Wet
Damaged Pipe Covering Showing Friable Insulation Material
mopping is recommended since water inhibits fiber
movement, thus preventing reentrainment during the
cleaning process. Dry dusting and sweeping will cause
reentrainment and should be avoided. If wet cleaning is
not feasible, a High Efficiency Particulate Absolute
(HEPA) filtered vacuum should be used. Conventional
vacuum cleaning equipment normally used in the school
is not equipped with a filter size small enough to collect
asbestos fibers and should not be used to clean in areas
of asbestos contamination. If conventional vacuum
cleaning equipment is used, fibers can be reentrained.
For more information on HEPA filtered vacuums, see
page II-4-2 of Part 2.
When should school officials be concerned about
asbestos material?
If friable asbestos material is present in the school
building, an exposure problem may exist. Chapter 3
outlines the recommended steps to identify friable
asbestos material and to undertake a control program
to reduce exposure.
Is pipe covering and boiler lagging of concern?
Friable asbestos material was used for many years in
pipe covering and boiler lagging until EPA prohibited
its application in 1975. Pipe covering and boiler lagging
do not create an exposure hazard unless the friable
insulation material is exposed and damaged.
Pipe covering and boiler lagging should be routinely
inspected. If the insulation material is exposed, retaping
or covering the damaged area will prevent asbestos
fiber release.
Is ceiling tile of concern?
Ceiling tiles are not friable and should be of no
concern.

Chapter 3: How To Conduct an Asbestos
Control Program
An asbestos control program begins with locating
friable material and determining whether the material
contains asbestos. If contamination of the building by
asbestos fibers is occurring or will likely occur,
corrective action should be taken to protect school
children and other users of the building from exposure.
A recommended approach for conducting an asbestos
control program is outlined in the following table.

Chapter
4: Inspecting for
Friable
Material
All areas including student, administrative,
maintenance, and custodial areas in the building should
be visually inspected for friable asbestos material. If
friable material is located, it must be sampled and
analyzed for asbestos content. The fact that material is
friable does not establish that asbestos is present.
Which schools should be inspected?
Schools built or renovated during the period following
World War II to 1978 should be inspected. Although
the spray application of asbestos materials for
fireproofing and insulation was prohibited in 1973 by
EPA, spray application for nearly all uses of these
materials was not prohibited until 1978.
Where will friable material be found?
Friable material is commonly found on steel support
beams and columns and on ceilings and walls of
classrooms, corridors, auditoriums, cafeterias,
machinery rooms, and storage rooms. It also may be
found on overhead surfaces of indoor pools and
gymnasiums.
What will friable material look like?
Friable material can have the following characteristics:
• Fluffy or spongy appearance (always applied by
spraying)

If friable material has been damaged or is
deteriorating, the material may be flaking or pieces may
be hanging from the surface of the material.
7
-------
Should inspections be made above suspended ceilings?
Inspections should be made above suspended ceilings.
Asbestos material may have been applied to the
original ceiling, steel beams, and other surfaces above
the suspended ceiling.
If the overhead space between the suspended ceiling
and original ceiling is part of the building's air
circulation system, fibers which have been released
from deteriorating or damaged material could travel
throughout the ventilation system to other areas in the
building.
Settled asbestos fibers or fallen ceiling material may
cover the upper surface of the suspended ceiling panels.
In this case moving or removing the panel will cause
fiber release.
When inspecting above suspended ceilings, the
following precautions should be taken:
• The ceiling should be inspected when the area is
not in use.
• If the overhead space is part of the air circulation
system (air plenum), the system should be shut down
during inspection.
• Only persons necessary to assist in the inspection
should be present.
• The National Institute for Occupational Safety and
Health (NIOSH) recommends that the person
inspecting wear an approved respirator. Contact the
NIOSH Regional Offices listed in Appendix E for
information on approved respirators.
Should building records be checked?
Building construction records can be checked as a
supplementary measure to determine if asbestos
materials were listed in the building specifications.
However, since building records may be unreliable,
checking records should not take the place of visually
inspecting school buildings.
What is the next step if friable material is located?
If friable material is located during inspection, a sample
of the material itself should be taken for laboratory
analysis. Chapters 5 and 6 have instructions for
sampling and information on recommended analytical
techniques to identify asbestos fibers in friable material
samples.
What if no friable material is located?
If no friable material is located during visual inspection,
a dated report stating that no material has been located
in the school building should be prepared. The report
should identify which areas of the building were visually
inspected and if the building records were also checked.
A copy of this report should be kept in a school
asbestos program file.

Chapter 5: Sampling Friable Material
The sampling and analysis of friable material are
extremely important. The decision to take corrective
action will depend, in large part, on the results of the
laboratory analysis. It is critical, therefore, that
sampling in schools is carried out properly and that
laboratory analyses are performed accurately.
The sampling procedures outlined in this chapter
should be followed closely. Improper sampling will
result in unreliable analyses and lead to either
unnecessary corrective action or to no action for
potentially hazardous material.
The choice of the analytical technique and an
analytical laboratory are also important. Chapter 6
contains information on analytical techniques and
laboratory selection.
Is sampling and analysis of friable material necessary?
Friable material should always be sampled and analyzed
for asbestos. Neither visual inspection nor checking
building records establish the presence of asbestos in
friable material. Suspect material could contain glass
fibers, cellulose, or other non-asbestos mineral fibers.
How to take a sample
If friable material is found, a representative sample
should be taken from within the material itself by
penetrating the depth of the material with a sample
container. It is important to penetrate the material
because it may have been applied in more than one
layer or covered with paint or a protective coating. This
kind of sample is called a bulk sample.
Taking a Bulk Sample
9
-------
One sample should be taken for approximately every
5,000 square feet of material having the same color and
texture (i.e., it is homogeneous in appearance).
Material of a different appearance should be sampled
separately.
Small classrooms, offices, or closets with less than
5,000 square feet of friable material should also be
sampled separately if different material is found.
Sampling is not difficult and can be performed by
school personnel if these procedures are followed:
(1) Use a small container such as a plastic 35 mm
film canister or a small, wide-mouthed glass jar with a
screw-on lid. The container should be dry and clean.
(2) Gently twist the open end of the container into
the material. A core of the material should fall into the
container. A sample can also be taken by using a knife
to cut out or scrape off a small piece of material and
then placing it into the container.
Be sure to penetrate any paint or protective coating
and all the layers of the material. If the sample
container cannot penetrate the material, consider
whether the material is really friable or not.
(3) Tightly close the sample container; wipe the
exterior of the container with a damp cloth to remove
any material which may have adhered to it during
sampling.
(4) Tape the container lid to prevent the accidental
opening of the container during shipment or handling.
(5) Label the sample container. This label should
identify the school and date the sample was taken, and
bear a unique identification (ID) number.
(6) Make a record of each sample by noting the date
the sample was taken, location of material sampled, the
area or room sampled, and the sample ID number.
(7) Send the sample to an analytical laboratory for
analysis (see Chapter 6).
What precautions should be taken during sampling?
To avoid causing unnecessary exposure to asbestos
fibers, the following precautions should be taken during
sampling.
© The material should be sampled when the area is
not in use.
© Only those persons needed for the sampling
should be present.
® The sample container should be held away from
the face during actual sampling.
o Do not disturb the material any more than
necessary.
e The material can be sprayed with a light mist of
water to prevent fiber release during sampling.
® If a large number of samples are taken, NIOSH
recommends that the sampler wear an approved
respirator. Contact the NIOSH Regional Offices listed
in Appendix E for information on approved respirators.
® If pieces of material break off during sampling,
wet mop the floors and areas where they have fallen.
Should the air be sampled?
Air sampling is the counting of fibers suspended in the
air. A known volume of air is pumped through a filter
where all suspended particles are collected. A
standardized air sampling method with specific
equipment and particle counting techniques is used by
the Occupational Safety and Health Administration
(OSHA) and industrial hygienists for evaluation of
airborne asbestos contamination. Unfortunately air
sampling by this standard method cannot show whether
the friable material actually contains asbestos fibers.
The method counts any particle of a certain size and
fibrous shape. The fibers that are counted may or may
not be asbestos.
Bulk sampling and analysis of the friable material
itself is the only method to determine whether or not
asbestos is present in the material.
10
-------
Chapter 6: Analysis of Bulk Samples
Why are PLM and XRD recommended for bulk sample
analysis?
Polarized Light Microscopy (PLM) is a technique used
to identify asbestos fibers by their shape and unique
optical properties. It is a relatively inexpensive and
quick method for identifying asbestos in bulk samples.
PLM is particularly suitable for examination of the
complex mixes of friable construction materials.
X-Ray Diffraction (XRD) is recommended where a
second, independent analytical technique is necessary to
confirm an analysis by PLM. It is a more expensive
analytical method than PLM.
For more information on these analytical techniques,
see pages 1-4—2 to 1—4—3 of Part 2.
Is Electron Microscopy recommended for bulk sample
analysis?
Electron Microscopy (EM) is not a recommended
analytical technique for bulk sample asbestos analysis.
EM is costly, time-consuming, and limited in
availability.
For more information on Electron Microscopy, see
pages 1-4-3 of Part 2.
Is Phase Contrast Microscopy recommended?
Phase Contrast Microscopy is a technique used to count
fibers present in air samples. It is unacceptable for
identification of asbestos in bulk samples' Do not"
accept analysis of bulk samples by Phase Contrast
Microscopy^
For more information on Phase Contrast Microscopy,
see pages 1-4-5 to 1-4-6 of Part 2.
Is there a standard analytical protocol for bulk sample
asbestos analysis?
A standard protocol for bulk sample analysis is not
currently available. However, guidelines have been
prepared for bulk sample asbestos analysis using PLM
and XRD. These guidelines are included as Appendix
H to this manual and should be made available to the
laboratories which perform the analyses of bulk
samples.
It is important that analyses of bulk samples are
performed by the recommended technique. In choosing
a laboratory, assistance from the State Asbestos
Program contact or the EPA Regional Asbestos
Coordinators is recommended.
What kind of analysis should be requested?
Analysis of friable material bulk samples by the
following techniques should be requested:
1) Polarized Light Microscopy (PLM)
2) X-Ray Diffraction (XRD) as necessary to
supplement the PLM method.
Polarized Light Microscope
11
-------
Are any laboratories certified for bulk sample asbestos
analysis with PLM?
No laboratories have been certified for performing bulk
sample analysis with PLM or XRD.
Laboratories which participate in the National
Institute for Occupational Safety and Health (NIOSH)
proficiency analytical testing program (PAT) for
certification by the American Industrial Hygiene
Association may or may not be qualified to perform
bulk sample asbestos analysis with Polarized Light
Microscopy. Typically these laboratories use Phase
Contrast Microscopy, which is inappropriate for the
differentiation of asbestos from other fibrous material
such as cellulose, hair, and glass fibers. Laboratories
proficient in air sample counting using Phase Contrast
Microscopy may lack both the equipment and expertise
to perform PLM identification of asbestos in bulk
samples.
What laboratories perform bulk sample asbestos
analysis?
It is important to select a laboratory competent in bulk
sample asbestos analysis. Since there currently is no list
of certified laboratories, locating a laboratory could be
difficult. The State Asbestos Program Agency or the
EPA Regional Asbestos Coordinator should be
contacted for their assistance and advice in laboratory
selection. The names and addresses of the State
Asbestos Program contacts are available from the EPA
Regional Asbestos Coordinators and on the EPA toll-
free information number (800-424-9065 or 554-1404 in
the Washington, D.C. area). The EPA Regional
Asbestos Coordinators are listed in Chapter 11.
Is guidance available to schools which plan to monitor
laboratory performance?
EPA will provide guidance to schools and school
districts which plan to undertake a program to ensure
good laboratory performance. Information can be
obtained by calling the EPA toll-free technical
assistance number (800-334-8571, extension 6892).
What should the laboratory report?
It is important that a complete written and signed
report of the analytical results be obtained from the
laboratory. The laboratory should report the following
information for each sample submitted:
(1) The sample ID number.
The laboratory results should be reported by
referencing each sample by its ID number.
(2) The analytical method used to analyze the
sample.
The report should name the analytical equipment and
the technique used to perform the analysis.
(3)a. A description of the sample appearance.
Good laboratory procedure requires that the analyst
note whether or not the bulk sample is a uniform
mixture.
(3)b. Whether the sample was homogenized before
analysis.
Asbestos materials were not always uniformly mixed
before application. If a sample is not homogenized prior
to analysis, some materials present in the sample may
not be detected.
(4) Percent of each type of asbestos present.
The analyst should report the types of asbestos
present and the estimated percent present. The estimated
precision associated with the percentage of asbestos
reported for each sample should be specified.
(5) Type and amount of the other fibrous materials
present in the sample.
The analyst should report what non-asbestos fibrous
materials are present in the sample and the percent
present, and provide the basis for that judgment.
Identification of the other fibers present will minimize
the reporting of false results.
(6) Comments on any other materials present.
(7) A description of the laboratory's quality control
program.
Laboratories should indicate the quality control
procedures followed in their PLM analysis.
Should samples be retained for analysis?
School officials may wish to request that the laboratory
retain the samples for up to six months or return them
to the schools so that they will be available if reanalysis
is necessary.

Chapter 7: Exposure Assessment
If bulk material analysis establishes that asbestos is
present in the sampled friable material, the potential
exposure of students and other users of the building
should be evaluated.
What should be considered in an exposure assessment?
Material condition, building structure characteristics,
and human activity are factors that will have
significance in any potential exposure situation
involving friable asbestos materials. These factors may
act singly or in combination to cause environmental
contamination and exposure of building users.
Experience has shown that eight factors generally
influence exposure potential.
1. Condition of Material: Material condition indicates
the extent of contamination and the likelihood of future
contamination. This factor is a combination of quality
of installation, adhesion of the friable material to the
underlying surface, material deterioration, and damage.
Delamination or deterioration of the material depends
on the characteristics of the material itself (whether it
shows signs of aging or loss of cohesive strength).
Damage is incurred by either accidental or intentional
contact. Evidence of debris can be a good clue to the
condition of material, which may vary from minor
deterioration and damage to widespread and severe
material disintegration.
2. Water Damage: Water can dislodge, delaminate,
and disturb asbestos materials that are otherwise in
excellent condition. Water can carry fibers in the slurry
to other areas in the building where evaporation will
leave a collection of fibers that can become
resuspended in the air. Water damage will have a
significant effect on selection of a corrective method,
essentially eliminating certain types of sealants.
3. Exposed Surface Area: The exposed surface area of
friable material has an effect on potential fiber fallout
levels and the possibility for contact and damage. A
useful criterion to apply for this factor is whether the
friable material is visible.
Asbestos material above suspended ceilings is not
considered as exposed. However, if the ceiling panels are
removed for routine maintenance activities above the
suspended ceiling or are damaged due to vandalism, the
asbestos material should be considered as exposed in that
area. Areas with louvers, grids, or other open ceiling
systems should be considered as exposed. However,
exposed does not mean accessible, which is a separate
factor.
4. Accessibility: If the material can be reached, it is
accessible and subject to accidental or intentional
contact and damage. Accessibility is a good indicator of
possible future exposure caused by contact and damage.
This factor should also include some consideration of
the proximity of friable material to heating, ventilation,
lighting, and plumbing systems requiring maintenance
or repair.
The behavior characteristics of the student population
should be considered in evaluating accessibility. For
example, students involved in sports activities may
accidentally cause damage to asbestos materials on the
walls and ceilings of gymnasiums. Material that is easily
accessible is also subject to damage by vandalism.
5. Activity and Movement: This factor combines the
effects of general causes that may result in contact and
damage of friable material. These causes include
air movement, building vibration from machinery or
any other source, and activity levels of students or
building workers. This factor is also an indicator of
future exposure potential. Its value will be low in
school libraries, offices, and most classrooms; moderate
in some classrooms and in school corridors; and can be
exceedingly high in gymnasiums and cafeterias.
6. Air Plenum or Direct Air Stream: Friable asbestos
material contained within an air plenum or in an air
stream, if undisturbed, has very low potential for
contaminating the building environment. However, it
must be considered since contact and damage may
occur during maintenance, repairs, and renovation. In
dealing with asbestos material located in air plenums,
special attention should be given to the management
system described in Chapter 8.
7. Friability: The asbestos materials can vary in
degree of friability. The more friable the material, the
greater potential for asbestos fiber release and
contamination. Sprayed asbestos material is generally
more friable than most troweled materials.
13
-------
8. Asbestos Content: The percentage for all the types
of asbestos present should be added for the total
asbestos content. With a high percentage of asbestos,
there are more fibers that can be released and
contaminate the building environment.
Is an exposure assessment straightforward?
Assessing exposure can be difficult. The eight factors
can vary from school to school; from room to room;
and sometimes from one area to another in the same
room. These factors should adequately describe most
situations. They are presented here to provide general
guidance, and exceptions can occur. Unique building
structure characteristics, unusual material condition, or
other considerations can influence the evaluation of
exposure.
How is an exposure assessment carried out?
The following steps are recommended for an exposure
assessment.
(1) Determine whether each factor is applicable in
the area where the asbestos material is present.
(2) If a factor or factors are applicable, note the
actual effects or situation associated with each factor.
For example, if the Accessibility factor is applicable,
consider whether (a) the material is subject to damage
during maintenance or repair work or; (b) the material
is accessible to students who may damage it during
sports activities or who will scrape, gouge, or hit the
material.
(3) Evaluate the exposure potential. Simply, if
asbestos fibers are being released and causing
contamination of the building environment, exposure of
students and other building users is occurring or is
likely to occur.
In carrying out the exposure assessment, it is
important that the factors are uniform throughout the
area being evaluated. If factors differ in one room or in
one area of a room, they are not uniform. In this case,
a separate evaluation should be made. For example, an
auditorium with both an inaccessible ceiling surface in
the stage area and a very accessible and damaged
surface in the audience area constitutes two different
areas.
The above discussion has described the factors relating to
exposure. Is there any system that ties these subjective
factors in a more precise way to aid the school official in
the decisionmaking for an exposure assessment?
EPA has developed a scoring system using a
mathematical formula which can be used as an aid in
assessing exposure and in deciding what kind of
corrective action to take. EPA is currently evaluating
the accuracy of the scoring system through field tests
and statistical analysis. It is EPA's intention to make
this scoring system and instructions for its use available
to school districts through the State Asbestos Program
contacts and through the Regional Asbestos
Coordinators.
Is air sampling necessary to evaluate the exposure
potential?
Air sampling is inappropriate to estimate asbestos
contamination and exposure. In the school
environment, it is virtually impossible to establish
exposure potential using standard air sampling
techniques. Air sample results from monitoring in
school buildings can be misleading if they are compared
to the Federal workplace air concentration levels
established by OSHA.
The standard optical microscopy method (Phase
Contrast Microscopy) used to analyze air samples has
technical restrictions. Only particles of a certain size
and fibrous shape are counted in an air sample. The
fibers that are counted may or may not be asbestos.
More importantly, the low air levels of asbestos that
have been found in school juildings are at the lower
limits of effectiveness for the optical microscopy
technique. Therefore, the results can be misleading.
The Federal workplace air concentration levels do
not apply to children. They were established for
asbestos workers in workplace environments.
Comparing air levels found in school buildings to the
Federal occupational standards is a totally ineffective
method of determining whether an exposure problem
exists.
What is the next step if exposure is occurring?
If exposure is found to be occurring or is likely to
occur, a corrective action may be warranted. This
decision will involve a judgment of the degree of the
exposure problem and what corrective method is
appropriate.
Chapter 8 discusses each of the corrective actions.
The charts on pages 18 and 19 of Chapter 8 should be
consulted for the advantages and disadvantages of each
corrective method and the conditions where each
method is appropriate or inappropriate.
Is corrective action required if there is no exposure
problem?
If it is determined that the exposure is negligible or that
there is no exposure potential, action can be deferred.
However, a continuing inspection program and
management system as described in Chapter 8 should
be implemented to ensure that if the situation changes,
the necessary steps will be taken to control exposure.
14
-------
Chapter 8: Corrective Action
If friable asbestos material is present and exposure is
occurring or will likely occur, corrective action should
be considered. The selection of the method or methods
of action should reach the most efficient long-term
solution after consideration of material condition,
location, function, and cost.
There are four approaches to controlling exposure:
(1) Removal: Asbestos material is removed and
disposed of by burial.
(2) Encapsulation: Asbestos material is coated with a
bonding agent called a sealant.
(3) Enclosure: Asbestos material is separated from
the building environment by barriers such as suspended
ceilings.
(4) Deferred action: No action is taken. The area is
inspected periodically for changes in exposure potential.
Removal, encapsulation, and enclosure are corrective
methods and can be used separately or in combination.
Removal completely eliminates the source of exposure
to asbestos and is, therefore, a permanent solution.
Both enclosure and encapsulation are containment
methods.
Since the asbestos material remains within the
building, enclosure and encapsulation should be
considered as temporary control measures. The length
of time before building renovation or demolition is
planned will be a factor in deciding whether to use
either of these methods. If the building is later
renovated or demolished, encapsulated and enclosed
asbestos material must be removed and disposed of
according to the EPA regulations discussed in Chapter
9.
Removal, encapsulation, enclosure, and deferred
action are discussed in the following sections. The chart
on pages 18 and 19 at the end of this chapter outlines
Wetting With Amended Water
each corrective action, lists advantages and
disadvantages, and notes the conditions under which
each method is appropriate.
Schools that do undertake a corrective action should
refer to Chapter 9 for information on the applicable
Federal regulations and proper work practices that are
required to protect workers and the building from
contamination during removal, encapsulation, or
enclosure.
Removal
For removal, all the asbestos material is taken off the
underlying surface, collected, and placed in containers
for burial in an approved waste disposal site. Removal
may require interruption of building activities. Vacation
periods in schools often provide a convenient time to
carry out the removal operation.
EPA has regulations that cover the removal of
asbestos material. The regulations require wetting of
the material prior to removal. Thoroughly wetting
asbestos material greatly reduces the release of fibers.
As the wet material is removed, only a small number of
fibers will be released and those that are will settle
rapidly to the floor rather than remain suspended in the
air.
Using water that has been amended with a wetting
agent (surfactant) is strongly recommended for all
removal operations. Amended water ensures greater
penetration of the material and reduces the amount of
water needed for the operation.
For more information on wet removal techniques, see
pages 11-4-2 to 11-4-3 and E-l to E-5 of Part 2.
Removal of Wet Asbestos Material From Overhead Surfaces
-------
Should consideration be given to the original purpose of
the material?
The original purpose of the material should be
considered when a corrective method is chosen.
Removed fireproofing material should be replaced to
maintain compliance with fire and building codes. If the
asbestos material served either an insulating or
acoustical function, a replacement material should have
similar characteristics.
Encapsulation
For encapsulation, the asbestos material is coated with
a bonding agent called a sealant. Sealants penetrate and
harden the asbestos material (penetrants) or cover the
surface of the material with a protective coating
(bridging sealants). The sealant prevents fiber release
from the asbestos material.
Sealants are applied over the surface of the material
Encapsulation of a Ceiling Surface
16
-------
using airless spray equipment at a low pressure setting.
Airless equipment reduces the pressure of the sealant
spray and the impact upon the friable asbestos material
surface, thus reducing fiber release during application.
Encapsulation should be limited to areas where
contact damage will not occur, a factor which may
preclude encapsulation in many areas of school
buildings because of high activity levels. Encapsulation
should also be limited to asbestos material that still
retains its bonding integrity since the material must
support the additional weight of the sealant.
Encapsulated material should be routinely inspected for
deterioration or damage.
For more information on the encapsulation method,
see pages 11-3-2 to 11-3-5 of Part 2.
What sealants are recommended for encapsulation?
An EPA contractor is evaluating sealants for asbestos
material to determine if they meet designated
specifications for flammability, smoke generation,
toxicity, and impact resistance. Until a report of the
sealant study (expected in May 1979) is published. State
Asbestos Program agencies and the EPA Regional
Asbestos Coordinators should be contacted for
information.
Enclosure
For enclosure, a barrier such as a suspended ceiling is
constructed between the asbestos material and the
building environment. Since the asbestos material
remains, fiber release and fallout can continue behind
the barrier, and accumulation of fibers will usually
occur. When the enclosure is damaged or entered for
maintenance, fibers collected behind the enclosure can
be released into the building environment.
For more information on the enclosure method, see
page 11-3-1 of Part 2.
Constructing a Suspended Ceiling Barrier
Deferred Action
If the exposure potential is considered negligible, action
can be deferred. A continuing inspection program
should be implemented as part of deferred action. The
asbestos material should be routinely checked for
deterioration or damage. If the condition of the
material changes so that fibers are being released and
contaminating the building environment, the exposure
potential should be reevaluated according to the
guidelines set out in Chapter 7.
Asbestos Material Management
Program
Encapsulation, enclosure, and deferred action leave the
asbestos material within the building. Assuming that the
exposure assessment is accurate and that an appropriate
corrective action has been taken, exposure of building
users will not occur.
The asbestos, however, remains and conditions can
change. For example, asbestos material can be damaged
by inadvertent or uninformed maintenance, repair, or
renovation activities.
Therefore, a management system should be
implemented to control maintenance, renovation, or
repair work by either school personnel or contractors.
These individuals should be informed that asbestos
material is present and trained in proper work
procedures to prevent damage to the material or to the
containment system. Work order procedures and school
building sign-in or entry systems are usually good
methods for alerting workers and school administrative
personnel that work in an area having asbestos material
is planned.
When should a school be closed for corrective action?
Generally, it is not necessary to close a school in order
to take a corrective action. However, a severe exposure
problem may require that the problem areas or rooms
be closed off until a corrective action is taken. Usually
this situation arises when there is a potential for high
contamination levels of asbestos caused by continuing
contact and damage of highly friable material.
Are there Federal regulations that must be followed
when taking a corrective action?
EPA and OSHA have regulations covering removal,
encapsulation, and enclosure of asbestos materials.
Chapter 9 contains a brief summary of these
regulations.
Some States and local governments may also have
regulations covering asbestos removal, encapsulation,
and enclosure. The State Asbestos Program Agency
should be contacted for information on State and local
government regulations.

Chapter 9: Specifications and Requirements
for Contractors
Removal, encapsulation, and enclosure operations must
be performed carefully. Poorly performed work can
cause a greater exposure problem than it eliminates.
Workers who do not remove asbestos material wet or
who damage the material during encapsulation or
enclosure cause uncontrolled release of asbestos fibers.
If fiber release is not properly contained in the work
area, workers will be exposed and widespread
contamination of the building will occur.
EPA and OSHA have issued regulations which cover
the removal, encapsulation, and enclosure of asbestos
material. Contractors are required to comply with both
regulations. EPA regulations require that removed
asbestos material be properly contained and disposed of
without release of asbestos fibers into the environment.
OSHA regulations require worker protection to prevent
exposure to hazardous levels of asbestos fibers.
It should not be assumed that all contractors will
comply with these regulations. Some contractors may
not know that compliance is required; others may
ignore the regulations in order to save time or money.
The EPA and OSHA regulations do not require
worker decontamination before leaving the job site and
clean-up of the contaminated work area after the job
has been completed. Therefore, school officials should
not only require contractors to comply with the EPA
and OSHA regulations but also require them to take
additional measures to ensure proper work practices
and protection of the building environment. Past
experience has shown that in many cases without
adequate supervision and instruction from supervisors
or management, workers will remove asbestos dry
instead of wet, work without respirators, eat or drink in
the work area, and leave the job site in their
contaminated worksuits and clothing.
For these reasons, there are a number of precautions
that should be taken:
(1) Become familiar with the EPA and OSHA
regulations and any State and local government
regulations that apply to asbestos material removal,
encapsulation, and enclosure.
(2) Require contractors submitting bids to explain in
their bids how they intend to comply with the
applicable regulations.
(3) Include specifications for asbestos fiber
containment, worker protection, and decontamination
of the work area in contracts and enforce the
requirements of the contract.
(4) NIOSH recommends that contractors who submit
bids provide evidence that they and their workers have
attended training courses dealing with occupational
safety and the health hazards associated with asbestos
material removal, encapsulation, and enclosure.
Information on contractor training materials is available
from the OSHA and NIOSH Regional Offices listed in
Appendices D and E.
(5) For any corrective action, notify the nearest
OSHA office listed in Appendix D when work will
begin and let the contractor know that OSHA will be
notified.
(6) For removal, notify the appropriate EPA
NESHAPS Coordinator listed in Appendix B before
the removal operation is begun.
(7) Recommend that the contractor contact the EPA
Regional Asbestos Coordinator for technical assistance.
The task of finding a qualified contractor may be
complicated by various political and economic
pressures. There may be pressure by people who are
unaware of the hazards of poorly performed work to
take action as soon as possible and as cheaply as
possible. Strict compliance with the EPA and OSHA
regulations and the recommended specifications takes
time and money. Contractors offering the lowest bid
may not be knowledgeable or capable of complying
¦with these regulations.
Short summaries of the EPA and OSHA asbestos
regulations follow. The full texts of these regulations
are printed in Appendices A and C. Recommended
specifications for removal, encapsulation, and enclosure
contracts are also included in this chapter. These
specifications can be used to guide school officials in
negotiating contracts which will ensure proper work
practices and a protected building environment.
EPA Regulations
EPA regulates the removal and disposal of asbestos
materials from ceilings, walls, pipes, and other surfaces
in buildings. The regulations were issued under the
EPA National Emissions Standards for Hazardous Air
Pollutants (NESHAPS). Written notification to the
NESHAPS Coordinator is required before asbestos
material can be removed.
The regulations require wetting of the asbestos
material before, during, and after stripping to prevent
dust emissions. The regulations use "stripping" to refer
20
-------
to taking asbestos off the ceilings, walls, pipes, etc.;
and "removal" to refer to taking stripped asbestos
material out of the building for disposal. If material
cannot be removed wet because of freezing
temperatures or damage to equipment by water, the
EPA NESHAPS Coordinator should be notified. In
some cases dry removal of asbestos material requires
written permission from EPA.
Stripped asbestos material must be placed in leak-
tight containers while still wet before removal from the
building. Containers of asbestos material may not be
dropped out of windows or down from one floor to the
next. Asbestos material must be transported within the
building in containers or dust-tight chutes.
Containers must be marked with a warning label (use
the OSHA label on page and be buried in a waste
disposal site meeting the requirements of Section 61.25
of the EPA regulations. In most cases a State-approved
sanitary landfill will be an acceptable disposal site.
Before contractors begin any asbestos removal
operation, they must send a written notification to the
EPA NESHAPS Coordinator before starting the
removal operation. The notification must contain the
following information:
(1) Name and address of the contractor.
(2) Address and description of the building, including
size, age, and prior use of the building and amount of
friable asbestos material present (square feet).
(3) Scheduled starting and completion dates for
removal.
(4) Procedures that will be employed to comply with
the regulation.
(5) The name and address of the waste disposal site
where the asbestos waste will be deposited.
When contractors send in notification of an asbestos
removal operation to EPA, the EPA NESHAPS
Coordinator will notify the OSHA office for that area
that a removal operation is planned.
See Appendix A for the full text of the EPA asbestos
regulations. Questions about the regulations and
compliance problems can be answered by the NESHAPS
Coordinator listed in Appendix B.
OSHA Regulations
OSHA regulates workplace practices and the airborne
concentration levels to which asbestos workers can be
exposed. The OSHA regulations apply to removal,
encapsulation, and enclosure operations involving
asbestos materials.
OSHA has established limits on the amount of
airborne asbestos to which a worker may be exposed on
a daily basis. Over an 8-hour period the average
airborne asbestos concentration level (also known as
the time weighted average (twa)) to which a worker
may be exposed may not exceed two fibers longer than
five micrometers per cubic centimeter of air (2f/cc). At
no time during the 8-hour period may the airborne
concentration exceed 10 fibers longer than 5
micrometers per cubic centimeter of air (lOf/cc). The
lOf/cc concentration is called the ceiling concentration.
NIOSH has recommended lowering the 8-hour twa to
0.1 fibers per cubic centimeter (O.lf/cc).
Contractors must use air monitoring to determine
whether the airborne concentration of asbestos exceeds
these exposure limits. The regulations prescribe the
method to be used for air monitoring and where and
how often air samples must be taken.
If the airborne concentration does exceed the
specified exposure limits (either the 8-hour twa or the
ceiling concentration), then the contractor performing
removal, encapsulation, or enclosure must:
(1) Provide employees with approved respirators. The
OSHA regulations require different types of respirators
under different conditions. The OSHA Regional Offices
listed in Appendix D can provide information on
respirator requirements. The NIOSH Regional Offices
listed in Appendix E can provide information on
approved respirators.
(2) Provide change rooms and two separate lockers
or storage containers so that employees can keep street
clothes and work clothes separate.
In addition, if the ceiling concentration is exceeded, the
contractor must provide his employees with protective
clothing.
The regulations require contractors to place caution
signs inside and immediately outside of the work area.
The signs must advise people entering the area of the
hazards of exposure to asbestos.
Containers of waste asbestos material must be
marked with a warning label which states:
CAUTION
CONTAINS ASBESTOS FIBERS
AVOID CREATING DUST
BREATHING ASBESTOS DUST MAY CAUSE
SERIOUS BODILY HARM
See Appendix C for the full text of the OSHA asbestos
regulations. Questions about the regulations and
compliance problems can be answered by the OSHA
Regional Offices listed in Appendix D. Information on
contractor training and occupational safety is also
available from these OSHA offices and the NIOSH
Regional Offices listed in Appendix E.

the work area. Still wearing their respirators, workers
shall proceed to the showers and remove their
respirators while showering with soap and water.
Workmen shall then dress into a new, clean disposable
coverall to eat, smoke, or drink. The new coverall can
be worn to reenter the work area.
H. The Contractor shall provide a respirator and
disposable coveralls, headcover, and footwear to any

4. Work Area Preparation
A. The Contractor shall set up a decontamination
facility outside of the work area which will consist of a
change room, shower area, and equipment area. The
decontamination facility shall be subject to the approval
of the official representative of the school.
B. The Contractor shall isolate the work area for the
duration of the work by completely sealing off all
openings and fixtures in the work area including, but
not limited to, heating and ventilation ducts, doorways,
corridors, windows, skylights, and lighting with plastic
sheeting taped securely in place.
C. The Contractor shall build double barriers of
plastic sheeting at all entrances and exits to the work
area so that the work area is always closed off by one
barrier when workers enter or exit.
D. All floor and wall surfaces in the work area shall
be covered with plastic sheeting taped securely in place
to protect from water damage [or damage by sealants],
E. Before the work is begun, the Contractor shall
wet clean all removable items and equipment not
located on the asbestos material, remove them from the
work area, and then return these items and equipment
to the work area after the job has been completed and
the area has been decontaminated.
F. The Contractor shall cover all non-removable
items and equipment in the work area with plastic
sheeting taped securely in place.
G. After work area isolation, the Contractor shall
take out all detachable electrical, heating, ventilation
equipment, and other items located on the asbestos
material, clean them before covering with plastic
sheeting taped securely in place, and return them to
their proper place after the job has been completed and
the work area has been decontaminated.
H. The Contractor shall remove all heating,
ventilation, and air conditioning system filters, pack
them in sealable plastic bags (6-mil minimum) for burial
in the approved waste disposal site and replace them
with new filters.
I. The contractor shall establish emergency and fire
exits from the work area. Emergency procedures shall
have priority.
5. Method of Removal
A. The asbestos material shall be sprayed with water
containing a wetting agent to enhance penetration. The
wetting agent shall be 50% polyoxyethylene ester and
50% polyoxyethylene ether (Aqua-GRO*), or the
equivalent, in a concentration of one (1) ounce in five
(5) gallons of water. A fine spray of the amended water
* Menlion of trade names or specific products does not constitute
endorsement by EPA
shall be applied to reduce fiber release preceding the
removal of the asbestos material. The material shall be
sufficiently saturated to prevent emission of airborne
fibers in excess of the exposure limits prescribed in the
OSHA regulations referenced in these specifications.
B. The asbestos material shall be removed in small
sections by two-man teams on staging platforms. Before
beginning the next section, the material shall be packed
while still wet into sealable plastic bags (6-mil
minimum) and placed into fiber or metal drums or skips
for transport. Bags, drums, and skips shall be marked
with the OSHA label prescribed by the OSHA
regulations referenced in these specifications. The
outside of all containers shall be clean before leaving
the work area.
C. All plastic sheeting, tape, cleaning material,
clothing, and all other disposable material or items used
in the work area shall be packed into sealable plastic
bags (6-mil minimum) and placed into metal or fiber
drums or skips for transport. The drums and skips shall
be marked with the OSHA label prescribed by the
OSHA regulations referenced in these specifications.
D. The Contractor shall transport the sealed drums
or skips to the approved waste disposal site. The sealed
plastic bags may be dumped from the drums into the
burial site unless the bags have been broken or
damaged. The damaged bags shall be left in the drum
and the entire contaminated drum shall be buried.
Uncontaminated drums may be recycled.
6. Decontamination of Work Area
A. The Contractor shall clean all surfaces in the work
area with water and/or with a High Efficiency
Particulate Absolute (HEPA) filtered vacuum. (A
HEPA vacuum will fail if used on wet material.) After
cleaning the work area, the Contractor shall wait 24
hours to allow for settlement of dust, and then wet-
clean all surfaces in the work area again. After
completion of the second cleaning operation, the
Contractor shall perform a complete visual inspection of
the work area to ensure that the work area is dust free.
The Contractor shall take two air samples within 48
hours after completion of all cleaning work. (Minimum
volume of air sample is 240 L).
B. If the official representative of the school finds
that the work area has not been decontaminated, the
Contractor shall repeat the cleaning and air monitoring
until the work area is in compliance.
C. After the work area is found to be in compliance,
all entrances and exits are unsealed and the plastic
sheeting, tape, and any other trash and debris is
disposed of in sealable plastic bags (6-mil minimum)
and buried in the approved waste disposal site.
23
-------
-------
7. Air Monitoring
A. Throughout the entire [removal, encapsulation]
and cleaning operations, air monitoring shall be
conducted to ensure that the Contractor is complying
with the EPA and OSHA regulations [and any
applicable State and local government regulations). The
school shall provide an air monitoring technician to
take air samples at the job site at no cost to the
Contractor.
B. Air monitoring will be conducted according to the
method prescribed by Section 1910.KX)l(f) of the
OSHA regulations.
C. Air monitoring shall be performed to provide the
following samples during the period of asbestos
[removal, encapsulation]:

Chapter 10; EPA School Survey
EPA plans to assess the extent of the asbestos material
problem in schools and to determine the need for
further Federal action to control exposure to asbestos
in school buildings. To aid in this evaluation, EPA
encourages school districts to complete the survey form
at the end of this chapter.
What information does the form request?
The form asks questions about the results of (1)
inspection for friable materials and (2) sampling and
laboratory analysis of friable materials for asbestos. It
also asks what kind of corrective action (removal,
encapsulation, enclosure, or deferred action) has been
or will be taken to control exposure to friable asbestos
material.
Where to send the form
School districts (or individual schools, if the school
district does not plan to file a report) should send a
copy of the completed survey form to their EPA
Regional Asbestos Coordinator. The Coordinators are
listed on the back of the survey form. In States which
have an Asbestos Program Agency, the school district
should contact the agency to determine whether the
reporting form should also be sent to the State. The
names and addresses of these State contacts are
available from the EPA Regional Asbestos Coordinator
and by calling the EPA toll-free information number
listed below:
800-424-9065
(in the Washington, D.C. area: 554-1404)
A copy of the reporting form should be kept by
school districts in an asbestos control program file.
When to complete the form
The survey form should be completed as soon as
information is available from schools. Since asbestos
control programs in schools may begin at different
times, school districts may want to file more than one
form.
If possible, officials should mail completed survey
forms before September 1, 1979.
Additional Reporting Forms
Additional reporting forms can be obtained by calling
the EPA toll-free information number (800-424-9065 or
554-1404 in the Washington, D.C. area).
Will reports on the survey results be available?
Depending on the data received, EPA will compile
monthly reports for the Regional Asbestos
Coordinators. EPA will also publish an interim status
report in September 1979 and a final report in February
1980. These reports will summarize the data received
and will contain nationwide projections on the extent of
the asbestos problem in schools and efforts to control
it. These reports will be available to the States and
local school officials upon request from the Regional
Asbestos Coordinators.

Chapter 11: Assistance From Federal and State
Agencies
The EPA Regional Asbestos Coordinators will
coordinate the EPA school asbestos program with the
States in their Regions. The other Federal agencies
participating in the program will provide assistance to
the States on matters of worker protection, contractor
training, and safety and health. Several toll-free
numbers will be operated by EPA and the Consumer
Product Safety Commission. The numbers are listed in
this chapter and in Appendix G.
Assistance From EPA
The EPA Regional Asbestos Coordinators can provide
information and assistance to the States. The
Coordinators are listed in this chapter. They will be
available to meet with State and local officials to discuss
the asbestos material problem and to answer questions
about the EPA school asbestos program.
A videotape supplementing the information contained
in this manual will be available to schools from the
EPA Regional Offices. The videotape will show how to
inspect schools and how to sample friable material, and
will also show removal, encapsulation, and enclosure
operations. The EPA Regional Asbestos Coordinators
should be contacted for copies of the videotape.
As part of the school asbestos program EPA will
conduct training sessions in the Regional Offices for
State and local officials and other interested individuals
and provide technical assistance to schools and their
contractors who undertake corrective actions. The
Regional Asbestos Coordinators should be contacted
for information on scheduling of training sessions and
the technical assistance program.

Assistance From State Asbestos
Program Contacts
Many States have programs or are developing programs
to control asbestos materials in schools and other
buildings. The names of persons who have been
designated by the Governors as the Asbestos Program
contact for each State are available on the EPA toll-
free information number. The Regional Asbestos
Coordinators can also be contacted for the names of
the State Asbestos Program Agencies.
School officials should check with their State Agency
before beginning a school asbestos control program.
Some States may already have an asbestos program and
will want schools to follow certain procedures for
inspecting, sampling and analysis, and taking corrective
actions.
Assistance From Other Federal
Agencies
Other Federal agencies can provide assistance to
schools which have questions about consumer products
containing asbestos and matters of occupational safety
and health.
(1) Consumer Product Safety Commission
The U.S. Consumer Product Safety Commission
(CPSC) operates a toll-free information number. School
districts with questions about consumer products that
contain asbestos can call:
800-638-8326
(in Alaska, Hawaii, Puerto Rico, Virgin Islands:
800-638-8333)
(in Maryland: 800-492-8363)
(2) Occupational Safety and Health Administration
The Occupational Safety and Health Administration
(OSHA) has regulations covering safe workplace
practices that must be followed during removal,
encapsulation, and enclosure of asbestos materials.
These regulations are summarized in Chapter 9 and are
printed in Appendix C.
Some States have assumed responsibility for
development and enforcement of their own
occupational safety and health standards following
approval from OSHA. A complete list of the approved
State Program Offices and Federal OSHA field
locations is included as Appendix D. Questions about
proper worker protection and respirator requirements
should be referred to the appropriate State Program
Office or Federal OSHA Offices listed in Appendix D.
To assist small business employers in meeting the
requirements of the Occupational Safety and Health
Act of 1970 Congress has authorized a joint federal
OSHA-State on-site consultation program. For
information on this free consulting service, employers
should contact the nearest State or Federal OSHA
Office listed in Appendix D.
(3) Department of Health, Education and Welfare
(DHEW)
A.National Institute for Occupational Safety and Health
The National Institute for Occupational Safety and
Health (NIOSH) can provide assistance on selection of
approved respirators and answer questions on
occupational safety and health. The NIOSH Regional
Consultants are listed in Appendix E.

(4) The following procedures shall be
used to prevent emissions of particulate
asbestos material to outside air:
(i) Friable asbestos materials, used
on any pipe, duct, boiler, tank, reactor,
turbine, furnace, or structural
member, shall be removed from any
building, structure, facility or installa-
tion subject to this paragraph. Such
removal shall occur before wrecking or
dismantling of any portion of such
building, structure, facility, or installa-
tion that would break up the friable
asbestos materials and before wreck-
ing or dismantling of any other por-
tion of such building, structure, facili-
ty. or installation, that would preclude
access to such materials for subse-
quent removal. Removal of friable as-
bestos materials used on any pipe,
duct, or structural member which are
encased in concrete or other similar
structural material is not required
prior to demolition, but such materials
shall be adequately wetted whenever
exposed during demolition.
(ii) Friable asbestos materials used
on pipes, ducts, boilers, tanks, reac-
tors, turbines, furnaces, or structural
members shall be adequately wetted
during stripping, except as provided in
paragraphs (dX4)(iv), (d)(4)(vi). or
(dXvtl) of this section.
(ill) Pipes, ducts, boilers, tanks, reac-
tors, turbines, furnaces, or structural
members that are covered or coated
with friable asbestos materials may be
taken out of any building, structure,
facility, or installation subject to this
paragraph as units or in sections pro-
vided the friable asbestos materials ex-
posed during cutting or disjoining are
adequately wetted during the cutting
or disjoining operation. Such units
shall not be dropped or thrown to the
ground, but shall be carefully lowered
to ground level.
(iv) The stripping of friable asbestos
materials used on any pipe. duct,
boiler, tank, reactor, turbine, furnace,
or structural member that has been
removed as a unit or in sections as pro-
vided in paragraph (d)(4)(lit) of this
section shall be performed In accord-
ance with paragraph (d)(4)(li) of this
section. Rather than comply with the
wetting requirement, a local exhaust
ventilation and collection system may
be used to prevent emissions to the
outside air. Such local exhaust ventila-
tion systems shall be designed and op-
erated to capture the asbestos particu-
late matter produced by the stripping
of friable asbestos materials. There
shall be no visible emissions to the
outside air from such local exhaust
ventilation and collection oystems
except as provided in paragraph (f) of
this section.
(v) All friable asbestos materials that
have teen removed or st-ipped shall be
adequately netted to ensure that such
materials remain wet durins all remain-
ing stages of demolition or renovation
and related handling operations. Such
materials shall not be dropped or thrown
to the ground or a lower floor. Such ma-
terials that have been removed or
stripped more than 50 feet above
ground level, except those materials re-
moved as units or In sections, shall be
transported to the ground via dust-tight
chutes or containers.
(vl) Except as specified below, the wet-
ting requirements of this paragraph are
suspended when the temperature at the
point of wetting is below 0*C (32°F).
When friable asbestos materials are not
wetted due to freezing temperatures, such
materials on pipes, ducts, boilers, tankj,
reactors, turbines, furnaces, or structural
members shall, to the maximum extent
possible, be removed as units or in sec-
tions prior to wrecking. In no case shall
the requirements of paragraphs (d) (4)
(iv) or (d) (4) (v) be suspended due to
freezing temperatures.
(vii) For renovation operations, local
exhaust ventilation and collection sys-
tems may be used. Instead of wetting as
specified in paragraph (d) (4) (ii), to pre-
vent emissions of particulate asbestos
material to outside air when damage to
equipment resulting from the wetting
would be unavoidable. Upon request and
supply of adequate Information, the Ad-
ministrator will determine whether dam-
age to equipment resulting from wetting
to comply with the provisions of this par-
agraph would be unavoidable. Such local
exhaust ventilation systems shall be de-
signed and operated to capture the asbes-
tos particulate matter produced by the
stripping and removal of friable asbestos
material. There shall he no visible emis-
sions to the outside air from such local
exhaust ventilation and collection sys-
tems, except as provided In paragraph
(f) of this section.
(5) Sources subject to this paragraph
are exempt from the requirements of
SS 61.05(a). 61.07. and 61.09.

ble emissions to the outside air from
the spray-on application of materials
containing more than 1 percent asbes-
tos. on a dry weight basis, used on
equipment and machinery, except as
provided in paragraph (f) of this sec-
tion. Materials sprayed on buildings,
structures, structural members, pipes,
and conduits shall contain less than 1
percent asbestos on a dry weighs basis.

tion.
(f) Rather than meet the no-vlsible-
emission requirements as specified bv
paragraphs (a), (c). (d). (e), (h), (j),
and (k) of this section, an owner or op-
erator may elect to use the methods spec-
ified by 5 61.23 to clean emissions con-
taining particulate asbestos material be-
fore such emissions escape to, or are
vented to. the outside air.
(g) Where the presence of uncombined
water is the sole reason for failure to
meet the no-vlsible-emisslon require-
ment of paragraphs (a), (c). (d). (e).
(h). (J). or (k) of this secilon, such fail-
ure shall not be a violation of such emis-
sion requirements.

(OSHA) Asbestos Regulations
(Code of Federal Regulations Title 29, Part 1910)
Section 1910.1001
(a) Definitions.
For the purpose of this section.
(1) "Asbestos" includes chrysotile, amosite,
crocidolite, tremolite, anthophyllite, and
actinolite.
(2) "Asbestos fibers" means asbestos fibers
longer than 5 micrometers.
(b) Permissible exposure to airborne concen-
trations of asbestos fibers.
(1) Standard effective July 7, 1972. The 8-hour
time-weighted average airborne concentra-
tions of asbestos fibers to which any
employee may be exposed shall not exceed
five fibers, longer than 5 micrometers, per
cubic centimeter of air, as determined by
the method prescribed in paragraph (e) of
this section.
(2) Standard effective July 1, 1976. The 8-hour
time-weighted average airborne concentra-
tions of asbestos fibers to which any
employee may be exposed shall not exceed
two fibers, longer than 5 micrometers, per
cubic centimeter of air, as determined by
the method prescribed in paragraph (e) of
this section.
(3) Ceiling concentration. No employee shall be
exposed at any time to airborne concentra-
tions of asbestos fibers in excess of 10 fibers,
longer than 5 micrometers, per cubic cen-
timeter of air, as determined by the method
prescribed in paragraph (e) of this section.
(c) Methods of compliance.
(1) Engineering methods.
(i) Engineering controls. Engineering con-
trols, such as, but not limited to, isolation,
enclosure, exhaust ventilation, and dust
collection, shall be used to meet the

tion of the 8-hour time-weighted average
airborne concentrations and of the ceiling
concentrations of asbestos fibers.
(ii) Sampling frequency and patterns. After the
initial determinations required by sub-
paragraph (1) of this paragraph, samples
shall be of such frequency and pattern
as to represent with reasonable accuracy
the levels of exposure of employees. In
no case shall the sampling be done at
intervals greater then 6 months for
employees whose exposure to asbestos
may reasonably be foreseen to exceed the
limits prescribed by paragraph (b) of this
section.
(3) Environmental monitoring.
(i) Samples shall be collected from areas
of a work environment which are rep-
resentative of the airborne concentra-
tions of asbestos fibers which may reach
the breathing zone of employees. Samples
shall be collected on a membrane filter
of 0.8 micrometer porosity mounted in an
open-face filter holder. Samples shall be
taken for the determination of the 8-hour
time-weighted average airborne concen-
trations and of the ceiling concentrations
of asbestos fibers.
(ii) Sampling frequency and patterns. After the
initial determinations required by sub-
paragraph (1) of this paragraph, samples
shall be of such frequency and pattern
as to represent with reasonable accuracy
the levels of exposure of the employees.

Appendix H: "Mineral Characterization of
Asbestos-Containing Spray Finishes"
by Arthur N. Rohl1, Arthur M. Langer,1 and Ann G. Wylie2
Composition of Insulation
Materials
Asbestos minerals are a common constituent of
sprayed-on materials including 1) fire proofing, thermal
and acoustical insulation and 2) decorative and
textured-spray finishes. In the first category, the
asbestos mineral most commonly used is chrysolite and
less frequently amosite and crocidolite. The three
asbestos minerals may be found singly, or mixed in
varying proportions. The formulations used by spray-
insulation contractors in the United States have varied
considerably depending on cost, availability, purpose
and other factors.
Many insulation materials consist of a mixture of
asbestos and rock wool fibers, the latter usually being
the major constituent. In other formulations non-
fibrous binders such as plaster of Paris, vermiculite.
perlite and clay are used. Wood pulp and paper fibers
are also commonly found.
Decorative and Textured-Spray
Finishes or Paints
Decorative and textured-spray finishes or paints are
frequently sprayed on walls and ceilings of multiple
dwellings, hotels, motels and public buildings. They are
commonly white, brown, gray, or blueish, generally
stuccoed in appearance with a "textured'" surface. It
may appear to be fine-grained and compacted, in
contrast to untamped thermal and fireproofing
insulation. Textured-spray finish may be comprised of
mixtures of crystalline filler materials, which may
include the following:

Carbonate minerals, usually calcite and/or dolomite;
Talc, often containing various concentrations of
tremolite, anthophvllite and serpentine minerals. This
latter mineral group may include chrysotile asbestos;
Fine-grained chrysotile asbestos ("floats" or "fines"),
may also be added to their formulations. Grav or
brownish colored finishes may contain amosite and
blueish finishes may contain crocidolite. Both
amphibole asbestos varieties may be found together as
well. The total asbestos mineral content may be as high
as 50 percent by weight, in these materials.
Mineral-, rock-, slag-wool or fibrous glass;
Various clay minerals and micas, such as kaolin,
vermiculite, chlorite, etc.;
Plaster of Paris, gypsum, quartz, organic binders and
thickeners are added to the above inorganic materials
to form a substance which can be trowelled or sprayed
on.
The mincralogical characterization of these asbestos-
containing spray finishes involves analysis of
assemblages which are mixtures of various materials
which never occur together naturally. Analysis of these
complex mixtures is. therefore, hindered in that the
"process of elimination" used to define "difficult
minerals" in natural assemblages, is lost to the analyst.
Methods and Problems of
Analysis
The inorganic constitutents of asbestos-containing
insulation generally are of such large particle size, arc
present in sufficient quantities, possess such unique
optical properties, that the use of the petrographic light
microscope as an analytical tool is acceptable and
justified. Yet, one should say at the outset that the
identification of the fibrous minerals in these materials
may be difficult because of a number of confounding
factors. Small particle sizes, changes in retardation
effects (interference colors) in small-sized particles,
difficulties in obtaining clear Becke lines (especially for
thin fibers), and complexity and range in chemical
compositions, often mitigate against the use of the
59
-------
polarizing microscope. Even in these cases, particles
such as carbonates, fibrous glass, perlite, vermiculite,
etc., may be quite readily identified on the basis of
optical characteristics. Identification of the asbestos
minerals may be difficult largely due to the effect of
fiber size, or, more specifically fiber diameter. Fibers
with diameters of <0.5(j.m will almost certainly limit the
usefulness of this technique as a definite identification
method. Yet, some optical properties which can be
determined on larger fibers, may be used to distinguish
between these materials. These are as follows:
I. To properly characterize spray materials by polarized
light microscopy, the following instrumentation and
accessories are required:
1. A polarizing microscope with a rotating stage and
360° marked scale;
2. The microscope should be equipped for visualization
of objects at magnification in the following range; 35X,
100X, 250X, 440X.
3. Standard equipment should include a substage
polarizer, and analyzer, and the following accessories:
mica plate, gypsum plate, quartz wedge. (One of us
[AGW] suggests that the quartz wedge is not really
necessary in the study of amphiboles or serpentine
minerals. Their intrinsic birefringence is not high
enough to require the accurate determination of the
order of interference color present. Again, the most
important controlling factor in retardation is size of the
particle.);
4. A set of immersion oils, with indices of refraction in
increments of 0.002, from 1.400 to 1.800;
5. A refractometer, suitable for accurate measurement
of indices of refraction, in the range as stipulated
above. It is suggested that a spindle stage may be
extremely useful in studying fibers which are large
enough to isolate approximately 0.5|xm in diameter.
The technique has recently been described in detail by
Bloss (American Mineralogist, 1978, Vol. 63, page
433).
II. Materials for Which Optical Characteristics Should
be Known:
Optical characteristics should be known for the
different asbestos varieties (chrysotile, amosite,
crocidolite), for acicular cleavage fragments of
anthophyllite and tremolite, and for the range of man-
made insulating fibers (fibrous glass, rock-wool,
mineral-wool, slag-wool). We are stressing the
importance of determining the inorganic mineral phases
for which biological potential has been established. In
addition, the complete analysis of these asbestos-
containing materials would require knowledge
concerning the optical characteristics of the more
common mineral components, clay, talc, mica, kaolin,
vermiculite, chlorite, gypsum, bassanite (plaster of
Paris), quartz, etc.
III. The Optical Characteristics to be Determined, and
Measured with Accuracy, Should Include the Following:
1. FIBROUS GLASS AND ROCK-WOOL
Form:
Normally forms straight rods, with parallel sides. Ends
of fibers may be fractured or tapered, especially if
fibers are derived from one of the "wool" varieties.
Wools of all varieties may form bulbous ends, blebs,
and "shot". A range of shapes may exist for glassy
components of the wool varieties (see discussion and
figures in McCrone's Particle Atlas). Dimensions of
length and diameter may range considerably; diameters
normally 8-13jxm, "shot" up to 100(xm. Several
varieties of fibrous glass may have diameters down to
< ljim. Diameters and length may be highly variable,
even for a fiber population from the same sample.
Color:
These amorphous fibers may be transparent, so that
fibers which lie beneath them are clearly visible.
Occasionally they may be "tinted", commonly brownish
(common in rock, slag, and mineral wools). Colors may
be visible, including yellow, pink, and reddish,
reflecting binders and/or resins (commonly observed on
fibrous glasses).
Birefringence:
These synthetic insulating fibers possess no birefringent
characteristics between crossed nicols. Fibers remain
dark in all orientations between crossed polarizer and
analyzer, indicating their amorphous character (optical
isotropy). Occasionally, a birefringence effect may be
observed on the edges of the glass fibers, attesting to
"strain birefringence; which may occur when the fiber
has been bombarded by particulate debris in the air
stream (as in glass fibers in filters).
Extinction:
No extinction characteristics are observable because of
the isotropic character of the materials.
Indices of Refraction:
There is only one index of refraction, which is the same
for all directions in relation to fiber morphology.
Refractive index may range from 1.53 to 1.62, as
related to the chemistry of the fiber. Most glass fibers
have an index of refraction <1.53, with most slag,
mineral, and rock wool >1.53.
60
-------
General Remarks:
The fiber form, transparency and lack of birefringence,
are the most characteristic features which distinguish
these man-made inorganic fibers from the asbestos
mineral fibers. No internal structure is visible, as
contrasted with the asbestos fibers which clearly show
the presence of internal fibrils or fiber sub-units.
2. CHRYSOTILE
Form:
Fibers occur as bundles of fibril units. The length: width
ratio usually exceeds 10:1, although short bundles may
be observed. Fibers may consist of "silky", undulating
fibrils which splay at the ends like an "unraveled" rope.
Kink bands may be present along the fibers which are
easily visualized between crossed nicols. Care should be
exercised in labeling blocky serpentine fragments as
chrysotile. Antigorite fragments, one of the major
constitutents of serpentine, may appear to be composed
of fibers due to the peculiar extinction and growth
characteristics it displays (herring bone growth).
Normally, in spray finishes, only chrysotile fiber is used
in a relatively pure form. Therefore we caution against
the use of these characteristics for the examination of
materials which may come directly from natural
sources, e.g., from rock quarry specimens.
Color:
Chrysotile fibers are normally colorless, but may appear
brownish in specimens derived from sources in which
the fiber was heated (e.g., steam pipes). Although
chrysotile displays no pleochroism, slight changes in
relief on rotation, especially in heated samples may
reflect itself as a "pseudopleochroic" change. This
characteristic is true for all of the birefringent asbestos
fibers, that is, for amosite, crocidolite, tremolite, and
anthophyllite. Occasionally, fibers may be somewhat
coated with organic resins, or a cementitious agent,
which may alter its characteristic color. Large fiber
bundles may contain intergrowths or coatings of opaque
iron oxide (magnetite).
Birefringence:
Chrysotile is birefringent, with thicker fibers showing
straw-yellow first-order colors. Although birefringence
is a crystal-chemical controlled constant, the displayed
colors are thickness dependent and are, therefore,
variable. One should, therefore, consult a standard
retardation color chart, so that one may derive an
estimate of mineral thickness based on observed
retardation color. Therefore, the observed retardation
color is highly variable and related to fiber diameter.
For example, first-order yellow-orange colors may be
seen on large fibers, as well as purple-blue colors.
However, very small fibers may show very slight
retardation, displaying a white-gray first-order effect.
To properly see these fibers between crossed nicols,
conoscopic light should be employed.
Extinction:
Extinction is normally parallel to the fiber length.
However, an "undulatory" extinction may occur,
especially if the fiber is curved and/or kinked. Use of an
accessory plate, when the fiber is turned 45° from its
extinction position, indicates the optical sign of
elongation is positive (length slow).
Indices of Refraction:
Most of the chrysotile used in fireproofing, thermal or
ornamental sprays is from Canada. The index of
refraction of light vibrating parallel to the fiber length
(Nz) is approximately 1.556, with indices increasing
proportionately with iron and nickel content of the
mineral. Some indices have been measured as high as
1.560, but these values are rare for chrysotile. The
birefringence (defined by Nz-Nx) averages about 0.008
for Canadian fibers. Therefore, on thick fibers, the use
of calibrated immersion oils will clearly show
differences in the two vibration directions.
General Remarks:
Chrysotile is by far the asbestos mineral most often
found in insulation materials. The fibers that are most
frequently confused with chrysotile are paper or cotton
fibers (cellulose). Fire retardant (borax) treated
cellulose is commonly used as fireproofing insulation. In
addition, since paper and cotton fibers are commonly
found in dust, casual observation may cause difficulty in
distinguishing between these fibers and chrysotile.
However, internal structure, extinction characteristics,
and indices of refraction, when carefully measured, will
clearly distinguish between cellulose and chrysotile. In
addition, since cellulose is combustible, this can be used
to distinguish between the two.
3. AMOSITE (ASBESTIFORM GRUNER1TE)
Form:
Amosite fibers, unlike single crystals of grunerite, are
composed of microscopic crystals, with the long fiber
axis in common alignment. These parallel crystals have
often been referred to as "fibrils" or "units" which
implies that they represent the smallest particles of
amosite. This is clearly fallacious since both amosite
and crocidolite form particles with fiber dimensions
only 600 angstroms in diameter. By light microscopy
one may clearly observe the "polyfilamentous"
character of the amphibole asbestos varieties, but the
investigator should be cautious in referring to these
features as "fibrils". Normally the fibers are straight
61
-------
and "splintery" with fewer curves and "kinks" than
observed for chrysotile. The length:width ratio tends to
be greater than chrysotile, with ratios of 10:1 or
greater. When fiber ratios increase up to 50:1 or
greater, curvature may be pronounced.
Color:
Amosite fibers tend to be brownish in most sections,
and may even show suggestions of pleochroism in
thicker fibers. Again, as with chrysotile, some suggested
change in "color" may be brought about by changes in
relief on rotation of the fiber. Opaque inclusions are
common, and principally consist of iron oxides
commonly associated with the fiber in the banded
ironstone ores.
Birefringence:
Amosite is birefringent, with high second-order colors
commonly observed. Again, this is primarily due to the
thick fibers one commonly encounters in spray
materials. Fibers with dimensions approaching the
30(xm standard thickness show the more "normal"
retardation effects cited in the literature. Occasionally,
on very thick fibers, the brown color may mask the
interference colors.
Indices of Refraction:
The index of refraction measured parallel to the fiber
axis normally ranges from 1.696 to 1.710 (Nz). The
index of refraction measured across the fiber diameter
varies from the indices anticipated for a single grunerite
crystal. X-ray diffraction evidence supports the
contention that the crystal units parallel to the fiber axis
are disoriented in the ab plane. Amosite fibers will
therefore not show indices characteristic of the
grunerite mineral. One of us [AGW] suggests that the
two measured indices (parallel and perpendicular to the
fiber axis) be designated Nx,, Nz,. This would more
correctly indicate that the disorientation of the small
crystals, which constitute the fiber bundle, may form a
"pseudo-indicatrix". Therefore, the indices measured
will be different from those of a "normal" grunerite.
The values observed across the fiber axis will tend to
range around 1.670 to 1.680. It is important to note
that amosite is often contaminated with other
amphiboles. Amosite from the Transvaal, South Africa,
tends to be contaminated with crocidolite. More
commonly, however, actinolite or anthophyllite fibers
may be observed. This has been the case in
characterizing some standards used in a number of
laboratories for biological purpose (seen by AGW and
AML).
General Remarks:
Amosite is considered to be the asbestiform variety of
grunerite. Optical properties, based on analogues with
grunerite indicates that amosite consists of intergrowths
of disoriented.crystallites with only the c-axis in
common alignment. Therefore, the extinction
characteristics, range of refractive indices, and sorption
characteristics, recorded for grunerite. are not identical
for amosite.1 Normally, the high range of indices of
refraction, and the brown coloration, and the presence
of sub-unit crystals, indicate a positive identification for
amosite.
4. CROCIDOLITE
Form:
Both crocidolite and amosite fibers tend to be more
straight and "splintery" than chrysotile asbestos. Fiber
composites, making up the fiber bundle, are clearly
visible and fibers with great length: width ratio tend to
curvilinear.
Color:
Thick fibers tend to be blueish or purple-blue in color.
Rotation of the stage shows these colors change in
intensity and hue. Standard color absorption
characteristics are available in optical mineralogy text
books, e.g., Kerr's Optical Mineralogy.'
Birefringence:
Although crocidolite is birefringent, the color of the
mineral is so intense that the interference color is often
obscured. The differences in the velocities of the
slowest and fastest rays are such that the birefringence
is extraordinarily small so that the color masks most
interference color effects.
Extinction:
Extinction is parallel to the fiber length, indicating the
average effect of the aggregates of crystal composites.
Measurement of sign of elongation indicates that it is
negative, with the fast ray (indicating the snallcst index
of refraction) parallel to the fiber length.
Indices of Refraction:
Measurement of the indices of refraction of the
crocidolite shows that most fibers have maximum values
slightly less than those measured for amosite. The
maximum value, measured across the fiber diameter, is
close to 1.700.
General Remarks:
The blue color of crocidolite, the highest index of
refraction, close to 1.700 and its polyfilamentous
character, are diagnostic for this mineral fiber.
62
-------
Crocidolitc is less commonly found in sprayed-on
materials than chrysotile and amosite. However, the
presence of amosite. should lead the analyst to look
further for crocidolite. as they may occur together.
General Characteristics of Other
Amphiboles
Although anthophyllite and tremolite are not
incorporated in these mixtures as commercial asbestos
minerals, they may occur as contaminants in talc. One
of the most common constituents of textured-spray
finishes is finely pulverized talc. Whereas amosite and
crocidolite asbestos possess the optical characteristics of
composite fibers, anthophyllite and tremolite appear,
on the most part, as single crystals, forming acicular
cleavage fragments when comminuted. Acicular
cleavage fragments generally possess optical continuity,
and do not possess splayed ends or internal sub-unit
fibrils. These materials are rectilinear, will tend to show
uniform extinction and possess optical properties
consistent with single crystals (correct extinction angles
will be present, especially true for tremolite acicular
cleavage fragments). Single acicular cleavage fragments,
will show "normal" amphibole cleavage parallel to
(110) or (210). Aspect ratios of such cleavage fragments
are generally less than 10:1. Tremolite tends to display
characteristics of single crystals (acicular cleavage
fragments), whereas anthophyllite appears more often
to be composed of composite fibers. This characteristic
of anthophyllite may be related to both its intergrowth
with talc and its intrinsic asbestiform morphology. The
differences in asbestiform characteristics are more
evident when examining such minerals by transmission
electron microscopy than by optical microscopy.
5. ANTHOPHYLLITE AND TREMOLITE
¦ Form and Color:
Anthophyllite fibers are usually colorless but sometimes
light brown. Some appear to be single crystals whereas
' others, generally large fibers, appear to be fiber
composites or bundles. Tremolite is usually colorless or
very pale green color.
Birefringence:
Anthophyllite and tremolite are birefringent with larger
fibers displaying moderate (second-order) interference
colors. Again, the retardation is enhanced because fiber
diameters are commonly in excess of the 30(im
reference thickness. Most anthophyllite fibers found as
contaminants in "fibrous talcs" tend to be long and thin
and of such a diameter as to preclude the acquisition of
good birefringence characteristics. Tremolite more
commonly occurs as short, wide particles, with
prismatic terminations.
Extinction:
The extinction for anthophyllite is parallel to the fiber
length with a positive elongation (length slow).
Tremolite possesses angular extinction, with maximum
extinction achieved at an angle of 10-15° with the long
cleavage fragment edge. The indices of refraction of
anthophyllite fibers tend to range considerably Their
values are consistently less (parallel to the fiber length)
than that observed for either amosite or crocidolite.
General Remarks:
If anthophyllite is present with thin fibers of tremolite
there may be difficulties in distinguishing between these
two mineral phases. Acicular cleavage fragments of
tremolite, present as a single crystal rather than
composites, may be distinguished from anthophyllite on
the basis of their angular extinction (about 10-15° with
the fiber edge). If tremolite is composed of
polyfilamentous fibers, then x-ray diffraction may be
used to distinguish between these phases. It is
important to note that the mineral talc may occasionally
occur in fibrous habit. Some talc mines contain large
proportion of talc fiber. These fibers may be
distinguished from the amphibole fibers on the basis of
indices of refraction and by birefringence. The general
statement may be made that all talc indices of
refraction are less than 1.600, whereas the indices of
refraction of amphiboles, commonly associated with
talc, possess indices greater than 1.600.
X-Ray Diffraction Analysis
X-ray diffraction analysis may be required to
differentiate among some of the mineral phases which
may be present in these materials. Using an x-ray
diffraction unit, equipped with an appropriate x-ray
detector, scanning goniometer, suitable x-ray target, an
x-ray pulse discrimination device, suitable data output
equipment, step-scanning Geneva gears, spray materials
may be pulverized by mechanical mills, and prepared
for examination by x-ray powder diffractometry. These
materials may be also examined in the continuous scan
mode of operation at a rate of one degree two theta per
minute. This rapid method may be useful for
determining the presence of amosite, crocidolite, the
serpentine minerals, talc, tremolite, and anthophyllite if
these materials are present in amounts of some 3-5%
or more by weight. It should be noted that the
continuous scan x-ray diffraction method is not specific
for chrysotile since reflection for this mineral cannot be
distinguished from those of non-fibrous serpentine
minerals (antigorite, lizardite) nor from kaolin and
some varieties of chlorite and vermiculite. Also,
asbestiform varieties of the amphiboles cannot be
distinguished from ordinary cleavage fragments of the
same minerals.

Studies have shown (e.g., Rohl, et.al., 1976)3 that x-
ray diffraction, using a step-scan mode of analysis, can
be used to detect tremolite and anthophyllite (when
present in a matrix of talc), in amounts as low as 0.1
and 2 percent by weight, respectively. Under most
conditions, serpentine minerals (including chrysotile
asbestos) can be distinguished from kaolin and chlorite
using the same analytical modalities. However, we
stress that the presence of sub-microscopic chrysotile
fibers must be confirmed by transmission electron
microscopy and selected area electron diffraction, since
x-ray diffraction techniques cannot.
The use of polarized light microscopy, immersion
oils, and standard accessory devices, may be used as a
basic tool characterizing the mineral assemblages of
asbestos-containing spray finishes. X-ray diffractometry
and electron beam techniques may be employed as
ancillary methods as well.
