     Under  the authority of section  126  of the
  Superfund Amendments and Rcauthonzalion Act
  of   1986   (SARA),  the  U.S   Environmental
  Protection   Agency  (EPA)  and ^ the  U.S.
  Occupational Safety and Health  Administration
  (OSHA) promulgated identical health and safety
  standards to protect workers engaged in hazardous
  waste operations and emergency  response.  The
  OSHA   regulations  became  effective   on
  March 6, 1990 and  are codified at 29 CFR
  1910 120 (54 FR 9294, March 6, 1989).  the EPA
  regulations also became fully effective on March 6,
  1990 and are  codified at  40 CFR 311  (54 FR
  26654, June 23, 1989).  The EPA  regulations
  incorporate the OSHA standards by reference.

     Although the two sets of standards contain
  identical substantive  provisions, EPA  and  OSHA
  address different audiences.  In states without an
  OSHA-approved   program,  federal    OSHA
  standards protect all private and federal employees
  engaged  in  hazardous waste  operations  and
  emergency  response; the EPA worker protection
  standards protect all state and local  government
  employees.  In states with an OSHA-approved
  program, the state  program  covers  all private,
  state, and  local  government  employees;  OSHA
  co\ers federal employees in those states.  Another
  Fact  Sheet, Hazardous  Waste  Operations  and
  Emergency  Response.   Uncontrolled Hazardous
  Waste Sites and RCRA Corrective Action (OS WER
  Publication No 9285 2-08FS), provides a general
  o\er\iew of the  worker protection standards  as
  they apply to operations conducted at uncontiollcd
  hazardous waste sues.

                        establishing and maintaining work zones, including
                        Support Zones, at hazardous waste sites   This

                        information.

                        PART 1: INTRODUCTION TO WORK ZONES

                            The worker protection standards at 29 CFR
                        1910.120(b) require that employers with employees
                        engaged in  hazardous  waste   operations at
                        uncontrolled hazardous waste sues develop and
                        implement a written health and safety program for
                        their employees.  The purpose of this program is
                        to identify, evaluate, and control safety and health
                        hazards, and provide for  emergency  response
                        during hazardous waste operations. As part of the
                        overall   health  and safety  program,   29 CFR
                        1910.120(d)  specifies that appropriate site  control
                        procedures must be implemented before clean-up
                        work begins, to minimize employee exposure to
                        hazardous substances  One of the basic elements
                        of a site control program is the delineation of
                        work zones.  This delineation specifies the type of
                        operations that will occur in each zone, the degree
                        of ha/.ard at  different locations \\nhin the site, and
                        I he areas at the  sue  that  should be avoided by
                        unauihon/ed or unprotected  employees

    EPA's  Standard  Operating  Safety  Guides
describes  the  process  for  establishing   and
maintaining work zones.  Although a site may be
divided into as many zones as necessary to ensure
minimal   employee  exposure   to   hazardous
substances, the three  most frequently  identified
zones are the Exclusion Zone, the Contamination
Reduction Zone (CRZ), and the Support Zone.
The purpose of establishing the zones is to  (1)
reduce  the  accidental  spread  of  hazardous
substances  by workers  or  equipment  from  the
contaminated areas to the clean areas; (2) confine
work activities  to the appropriate areas, thereby
minimizing the likelihood of accidental exposure;
and (3) facilitate  the  location  and evacuation of
personnel in case of an emergency. Movement of
personnel and  equipment among these zones is
minimized and restricted to specific access control
points  to   prevent  cross-contamination  from
                                                contaminated  areas  to   clean   areas.     A
                                                representation of  the  three  most  commonly
                                                designated work  zones is found in  Exhibit 1.  A
                                                description of each zone is provided below.

                                                Exclusion Zone

                                                    The  Exclusion Zone  is  the  area where
                                                contamination does or could occur and the greatest
                                                potential for exposure exists. In order to separate
                                                the Exclusion Zone from the rest of the site, the
                                                outer boundary of  the Exclusion Zone, known as
                                                the Hotline, should be clearly marked.  Access of
                                                personnel and  equipment  to  and  from  the
                                                Exclusion Zone  should be restricted  by access
                                                control points on the zone's periphery. All persons
                                                who enter the Exclusion Zone should  wear the
                                                appropriate level of personal protective equipment
                                                (PPE) for the degree and types of hazards at the site
                                                                   US EPA HO.& Chemical Libraries

-------
The Exclusion Zone also may be subdivided
into different areas of contamination, based on the
known or expected type and degree of hazard or
the incompatibility of waste streams. If the
Exclusion Zone is subdivided in this manner,
additional demarcationS and access control points
may be necessary.
Contamination Reduction Zone
As the transition area between the
contaminated area and the clean area, the CRZ is
the area in which decontamination procedures take
place. This zone is designed to reduce the
probability that the Support Zone will become
contaminated or affected by other site hazards.
Due to both distance and decontamination
procedures, the degree of contamination in the
CRZ generally will decrease as one moves from
the Hotline to the Support Zone.
Support Zone
1,
The Support Zone is defined as the
uncontaminated area where workers should not be
exposed to hazardous conditions. Any potentially
contaminated clothing, equipment, and samples
must remain outside of the Support Zone until
decontaminated. The Support Zone is the
appropriate location for the command post,
medical station, equipment and supply center, field
laboratory, and any other administrative or support
functions that are necessary to keep site operations
running efficiently. Because the Support Zone is
free from contamination, personnel working within
it. may wear normal work clothes, and access to
and from the area is not restricted for authorized
site personnel. Such personnel, however, should
receive instruction in the proper evacuation
procedures in case of a hazardous substance
emergency.
PART 2: SITE CHARACTERIZATION -- DATA
COLLECTION
To establish a Support Zone, the specific
hazards and the degree of potential employee
exposure at the site must be considered. The site
characterization, as specified in 29 CFR
1910.120(c), is the basis for developing the site
health and safely plan (HASP). and provides
information needed to identify site ‘iazards, select
proper PPE, and implement safc work practices.
Site chat acteri7at lofl generally proeecds in three pha.
• Prior to site entry, an off-site
characterization, including data gathering
and perimeter reconnaissance.
• An on-site survey.
• Ongoing monitoring to provide a
continuous source of information about
site conditions.
Off-site characterization and the on-site survey
are discussed below. Ongoing monitoring is
discussed in Part 4 of this Fact Sheet, Ensuring
Integrity of Work Zones.
Data-Gathering Prior to Initial Site Entry
The initial stages of site characterization must
be accomplished off-site, so as not to endanger the
health and safety of workers. For example, at new
uncontrolled hazardous sites, or at those sites with
areas that have not been evaluated, the range of
potential hazards and exposure risks is unknown.
As much information as possible should be
obtained during off-site characterization tO
evaluate the hazards and institute preliminary
controls for protecting initial entry personnel.
Once the off-site characterization is completed and
the appropriate information is obtained, the
information is used to develop an initial draft of
the site-specific HASP. (For more information on
developing a HASP, refer to the fact sheet
Hazardous Waste Operations and Emergency
Response: Uncontrolled Hazardous Waste SIZeS and
RCRA Corrective Action, OSWER Publication No.
9285.2-O8FS, 1991.)
29 CFR 1910. 120(c)(i) through (c)(viii)
identifies the generic information that must be
considered and evaluated before designated
personnel enter a site. These requirements are
listed in Exhibit 2, along with resources that can
be useful for obtaining the required information.
These information sources include general
background documents (e.g., area maps), site
records, interviews with persons who have
knowledge about the site, and perimeter
reconnaissance.
Interview/Records Research. Records of the
site or interviews with persons who have
knowledgc of the site can provide useful
information about the potential hazards at a site

Perimeter Reconnaissance. In addition to the
interview/records research, data-gathering at the
site perimeter may help in identifying site hazards
and determining the appropriate level of PPE for
the initial site entry Many of the activities that
occur during perimeter reconnaissance, including
making visual observations, monitoring
atmospheric concentrations of airborne pollutants,
and collecting soil samples, are similar to the
activities that occur during the initial site entry.
Perimeter reconnaissance activities, however, are
generally not as extensive or specific as the
activities undertaken during the on-site survey. To
determine the scope and level of effort for the
perimeter reconnaissance, the information from
the interview/records research should be evaluated.
Historical data on chemicals stored at the site, for
example, may help to identify the appropriate air
monitoring techniques for the perimeter
reconnaissance.
Initial Site Entry and Data Collection
The goal of the on-site survey is to gather the
additional information needed to identify the risks
and hazards presented by the site, so that the work
zones can be established and the appropriate
controls, PPE, and medical monitoring program
can be selected for the tasks that will be performed
at the site Risks that should be considered are
specified in 29 CFR Part 1910.120 (c)(7) and are
listed in Exhibit 4.
Immediately upon entering the site, entry
personnel should monitor the air for immediately
dangerous to life and health (IDLH) and other
conditions that may cause death or serious harm
(e g., combustible or explosive atmospheres, oxygen
deficiency, toxic substances) and monitor for
ionizing radiation. in addition, entry personnel
should visually observe for signs of actual or
potential IDLH hazards or othcr dangerous
conditions. Exhibit 5 provides examples of visible
indicators of potential IDLH hazards and other
dangerous conditions.

EXHIBIT 3
Sources of Site-Specific Information
• Company records, receipts, logbooks, or
ledgers that describe the activity that
occurred at the site.
• Waste storage inventories and manifests
or shipment papers.
• Records from state and federal pollution
control regulatory and enforcement
agencies, state Attorney General’s Office,
state occupational safety and health
agencies, state Fire Marshal’s office.
• Water and sewage district records.
• Previous survey, sampling, and ionitoring
results.
• Local fire and police department records
• Site and aerial photos.
• Media reports (all information from the
media should be verified)
• Interviews with personnel (all interview
information should be verified)
• Interviews with nearby residents (note
possible site-related medical problems and
verify all information from interviews).
• Maps (c g, USGS, land use, etc)
• Meteorological data (e.g., wind direction,
temperature profiles)
If IDLH hazards or other dangerous conditions
are not present, or if proper precautions can be
taken, the survey can continue. At a nuniniwii , the
ininal on-site survey should consist of a visual survey
for potential hazards and air monitoring.
Visual Survey. An accurate and
comprehensive visual survey of the site will assist
in identifying potential hazards and determining
where additional information (e.g., air monitoming,
sampling of soil or conlalneis) may be needed.
EXHIBIT 4
Risks to Consider
29 CFR 1910.120 (c)(7)
Risks to consider include, but are not limited
to:
• Exposure exceeding the permissible
exposure limits (PELS) and published
exposure levels.
• IDLH concentrations.
• Potential skin absorption and irritation.
• Potential eye irritation.
• Explosion sensitivity and flammability
ranges.
• Oxygen deficiency.
EXHIBIT 5
Visible Indicators of
Potential IDLH and Other
Dangerous Conditions
• Large containers or tanks that must be
entered.
Enclosed spaces such as buildings or
trenches that must be entered
• Potentially explosive or flammable
situations (indicated by bulging drums,
effervescence, gas generation, or
instrument readings)
• Extremely hazardous materials (such as
cyanide, phosgene, or radiation sources)
• Visible vapor clouds
• Areas where biological indicators (such as
dead animals or vcgciaiion) arc located

-------
This visual survey should include the following
activities:
• Noting the types of containers,
impoundments, or other storage systems
(e.g., paper or wood packages, barrels or
drums, tanks, lagoons).
• Noting the condition of waste containers
and storage systems (e.g., undamaged,
rusted or corroded, leaking)
• Noting the types and quantities of
material in containers (e.g., full or empty;
labels indicating corrosive, explosive,
flammable, radioactive, or toxic materials).
• Noting the physical condition of the
materials (e.g., solid, liquid, or gas,
conditions conducive to contact).
• Noting any unusual conditions (e.g.,
clouds, discolored liquids, oil slicks,
discolored soil, free-standing liquid,
stressed vegetation).
• Determining the potential pathways of
exposure and dispersion (e.g., air, soil,
surface water, ground water).
• Noting any indicators of potential
exposure to hazardous substances (e.g.,
dead fish, animals, or vegetation; pools of
liquids; foams or oils on liquid surfaces;
deteriorating containers; discolored soils).
• Identifying natural wind barriers (e.g.,
buildings, hills, tanks).
The results of the visual survey may help to
identify a potential location for the Support Zone,
which can be confirmed through air monitoring
and soil sampling.
Mr Monitoring. The purpose of air
monitoring is to identify and quantify airborne
contaminants in order to determine the level of
worker protect ion and identify additional medical
monitoring needs in any given area of the site Air
monitoring should be used to confirm that the
areas considered for the Support Zone do not
contain concentrations of hazardous substances
that require worker protcction The two methods
that generally arc available for identifying andfor
quantifying airborne contaminants are (1) on-site
use of direct-reading instruments and
(2) laboratory analysis of air samples obtained by
gas sampling bag, filter, sorbent, or wet-
contaminant collection methods.
Direct-reading instruments may be used to
rapidly detect flammable or explosive atmospheres,
oxygen deficiency, certain gases and vapors, and
ionizing radiation, as well as to identify changing
site conditions Because direct-reading instruments
provide information at the time of sampling and
allow for rapid decision-making, they are the
primary tools of initial site characterization. All
direct-reading instruments, however, have inherent
coiistraints in their ability to detect hazards.
Direct-reading instruments detect and/or measure
only specific classes of chemicals and are usually
not designed to detect airborne concentrations
below 1 ppm. In addition, many of the direct-
reading instruments that have been designed to
detect one particular substance also detect other
substances and, consequently, may give false
readings. Direct-reading instruments must be
operated, and their data interpreted, by qualified
individuals using properly calibrated instruments and
relying on chemical response curves. Additional
monitoring should be conducted at any location
where a positive instrument response occurs.
Exhibit 6 lists several direct-reading
instruments and the conditions and/or substances
they measure. Additional information concerning
direct-reading instruments is available in the
references.
Because direct-reading instruments are
available for only a few specific subsiances and are
rarely sensitive enough to detect low
concentrations of hazardous substances that may
nonetheless present health risks, air samples must
also be collected and analyzed in a laboratory
Exhibit 7 lists some sample collection and
analytical methods that are appropriate for certain
types of substances that are likely to be
encountered at hazardous waste sites. Additional
information concerning air sampling and
monitoring is available in the references listed in
Part 5 of this Fact Sheet.

adequate to determine the appropriate level of
PPE, to establish additional medical monitoring
needs, and to define work zones. For many sites,
however, consideration of planned site activities
may re eal the need for more extensive
environmental sampling. Analysis of surface soil
and soil borings may be required if site workers are
expected to be exposed to surface and subsurface
soil that max’ be contaminated Ground water or
surface water sampling may be necessary if site
workers are likely to be exposed via these media.
To determine whether additional monitoring is
required to designate work 7oncs, the results of the
air monitoring sur ey and visual characterization of
site hazards and contaminants should be reviewed
and potential l)ath ’aYS of contaminant dispersion
should be evaluated If there i any question that

contaminants may warrant special considerations.
For example, when sampling for the extent of
contamination of a dioxin site, tiered sampling and
designed grid-laying approaches should be
considered to achieve the 95 percent confidence
level. Additional information concerning soil
sampling is available in the references listed in
Part 5 of this Fact Sheet.
PART 3: SITE CHARACTERIZATION --
SELECTION OF WORK ZONES
After the off-site and on-site data collection
are complete, the collected information is used to
establish work zones. In addition, the HASP is
revised to address the specific on-site hazards.
Data Compilation
All of the information should be compiled in
a format that facilitates a decision concerning the
placement of work zones. A site map can provide
a useful format for compiling the collected data.
The locations of all the potential hazards that were
identified through the interview/records research,
the perimeter reconnaissance, and the initial on-
site survey should be plotted on the map. The
map should indicate both the hazards that were
observed and any areas that interviews or records
suggest may be contaminated with hazardous
wastes. In addition, all sampling results from the
On-site and off-site surveys should be plotted on
the map. It is important to record locations where
hazardous substances were detected and locations
where hazardous substances were not detected.
The absence of sampling results should not be
considered evidence that an area is clean.
Information concerning exposure pathways,
particularly the predominant wind direction, also
should be included on the map.
Data Evaluation
After all available site characterization data
have been compiled, the data are used to select a
location for the Support Zone. One of the most
important criteria for selection of an area for thc
Support Zone is that it must be located in a clean
area The Support Zone should be in an area that
is known to be free of elevated (i.e. higher than
background) concentrations of hazardous
substances. When evaluating on-site
concentrations of hazardous substances, it is
important to consider the background
concentrations of these substances in the area.
Non-zero background concentrations of hazardous
substances may be present at some sites.
The size and position of the Support Zone
also may be directly affected by the size of the
exclusion and contamination reduction zones For
example, the Support Zone may be constrained by
the distances needed to prevent an explosion or
fire from affecting personnel outside the Exclusion
Zone, or the physical area required for activities in
the Exclusion Zone In addition, the Support
Zone should, whenever possible, be upwind from
the Exclusion Zone. The Support Zone should be
located as far from the Exclusion Zone as
practicable. Whenever possible, line-of-sight
contact with all activities in the Exclusion Zone
should be maintained. Accessibility to support
services (e.g., power lines, access roads, telephones,
shelter, and water) also must be considered in
selecting a Support Zone. The expected duration
of the removal action also will affect the placement
of work zones.
It is also conceivable that the Support Zone
may inadvertently become contaminated after site
remediation begins, despite everyone’s best efforts.
For example, changes in wind speed and direction,
temperature, and rainfall may result in exposures
different from those experienced during the initial
on-site survey. The integrity of the Support Zone
should be reconfirmed during remedial activities
PART 4: ENSURING INTEGRITY OF WORK
ZONES
Several procedures can be used to ensure that
the area chosen for the Support Zone remains
clean during removal or remedial operations. Use
of site controls will minimize the transfer 01
contamination to the Support Zone. In addition,
periodic monitoring ol the Support Zone will
indicate whether changes in site activities or
conditions have resulted in contamination In the
event that contamination has occuried, the
boundaries ol work ioncs should he reevaluated
Other Considerations
S

-------
Use of Site Controls
The CRZ is designed to reduce the probability
that the clean Support Zone will become
contaminated or affected by other site hazards.
The distance between the Exclusion and Support
Zones provided by the CRZ, together with
decontamination of workers and equipment, limits
the physical transfer of hazardous substances into
clean areas. The boundary between the Support
Zone and the CRZ, called the contamination
control line, separates the Support Zone from an
area of possible low contamination. Access to the
CRZ from the Support Zone should be through
two access control points, if feasible: one for
personnel and one for equipment. Persons
entering the CRZ should be required to wear PPE
appropriate for the degree and types of hazards
they may encounter when working in this area. To
reenter the Support Zone from thQ CRZ, workers
should remove gross contamination, doff any
protective clothing, leave equipment in the CRZ,
and exit through the personnel access control
point.
Periodic Monitoring of Support Zone
A monitoring and sampling program for the
Support Zone should be established to ensure that
this area remains free from contamination.
Monitoring should take place on a routine basis
and whenever exposure is likely to change.
Situations where additional monitoring may be
appropriate are specified in 29 CFR 1910.120
(h)(3) and are listed in Exhibit 8 Increased
concentrations of hazardous substances in air, soil,
or other environmental media may indicate a
breakdown in site control procedures or a change
in on-site conditions. In addition, site personnel
should be constantly alert to changes in site
conditions or the presence of any potentially
dangerous situations. Exhibit 9 lists the
monitoring and sampling activities that may be
conducted to ensure that the Support Zone
remains clean.
Considering Additional Site Characterization
Information
Additional information concerning locations of
contaminated environmental media may become
available during monitoring or in the later stages
of site investigation and clean up, IxirticularlY for
remedial actions. For example, more detailed soil
sampling will occur during the site inspection (SI)
and remedial investigation (RI). This additional
information may indicate that areas initially
considered clean are, in fact, contaminated The
location of the Support Zone should be
reevaluated whenever new site characterization
studies are conducted.
EXHIBIT 8
Conducting Additional Monitoring
29 CFR 1910.120 (h)(3)
Situations that require consideration of the
possibility that exposures have risen are:
• When work begins on a different portion
of the site.
• When contaminants other than those
previously identified are being handled
• When a different type of operation is
initiated (e.g, drum opening as opposed to
exploratory well drilling)
• When employees are handling leaking
drums or containers or working in areas
with obvious liquid contamination (e g, a
spill or lagoon).
