Site-Specific Emergency Information
And Hazardous Assessment Section

7-Eleven Store #19847
1610 South Croatan Highway
Kill Devil Hills, NC

SITE DESCRIPTION
7-Eleven Store No. 19847 is currently an active gasoline station / convenience store. The No. 2 tank
is currently out of operation. The following tasks will be conducted: installation of soil borings; filling
the No. 2 underground storage tank (UST) with foam; and the installation and sampling of site
monitoring wells.
BRIEF SITE HISTORY
The No. 2 tank is no longer in service. AECOM is overseeing the filling of the No. 2 tank, and is
conducting soil borings and monitoring well installation. At this time, no release or spill is known.
TYPE OF WORK TO BE PERFORMED
The No. 2 tank will be abandoned in place. Per NC DENR closure requirements, a monitoring well will
be installed in a down-gradient direction. Gasoline sales have ceased prior to this project and the
area encompassing the existing canopy and tanks will be fenced off and remain inaccessible to the
public throughout construction.
The protection of AECOM employees, subcontractors, and the public is a major concern during tank
closure project design and implementation. Several health and safety concerns require evaluation and
include excavation/trenching hazards, confined space hazards; toxic, flammable and/or oxygen
deficient atmospheres; hot work and cold cutting operations; tank removal; physical hazards; and
others.
Although AECOM employees do not actually perform underground storage tank abandonment
operations, they may oversee, or be present during, operations performed by contractors or
subcontractors which involve the removal or closure of underground storage tanks. It is therefore
important that AECOM employees be aware of the hazards associated with, and the safe work
procedures for, performing underground storage tank removal operations.
During the removal of the USTs, AECOM will be on-site to manage the environmental impacts.
Specifically, AECOM will:
If present, oversee the operation and maintenance of water containment/treatment system
equipment (i.e. tanks, carbon vessels, filters) for dewatering operations;
Collect compliance samples for discharges from water treatment system (if present);

Screen excavated soils from the tank pit and beneath piping using direct-reading air
monitoring instrumentation and/or test field kits to ensure that potentially impacted soils are
properly managed;
Collect post-excavation soil samples from tank pit and beneath piping for subsequent
laboratory analyses; and
Collect grab groundwater samples, if present and required by regulatory agency, from the
tank pit, for subsequent laboratory analyses.

AECOM will not:

Enter a confined space (i.e. UST, excavation) and shall not issue, sign off or approve a
confined space permits that is issued by subcontractors or any other entity;
Enter the underground storage tank excavation for any reason due to the potential cave-in
and atmospheric hazards. Soil samples from the excavation should be collected with a
remote sampling device or from the bucket of the backhoe.
The following U.S. Safety, Health & Environment (SH&E) Safety Operating Procedures (SOP) should
be reviewed where appropriate:
SHE SOP 715 - Underground Storage Tank Removal
SHE SOP 714 - Excavation and Trenching
SHE SOP 713 - Confined Spaces

Additional SOPs may be applicable dependent upon the scope of work. The complete SH&E SOP
Library can be accessed through the AECOM Intranet Safety, Health & Environment page.

1.0 Introduction
1.1 AECOM Environment Safety Policy
AECOM Environment (AECOM) is committed to providing our employees with a safe and healthy
work environment. It is not only our obligation to each other, but also a sound business practice to do
so. Work related injuries and illnesses cause needless pain and suffering, cost money, and adversely
affect our reputation with our clients. Every attempt shall be made to eliminate the possibility of injuries
and illnesses. No aspect of the company's activities, including expediency and cost, shall take
precedence over the health and safety of our employees.
1.1.1 Maximum Duration of the Work Day for Field Activities
An employee may not work a shift that exceeds 16 hours in duration. For the purpose of this policy,
the work shift includes time spent at lunch and on break. If an employee works more than one shift
during the course of a calendar day, the total number of hours worked in that day cannot exceed 16
hours. Exception: If work is to be done continuously in ambient air temperatures of less than 20º F,
the Site Safety Officer and Field Manager will use a guideline of limiting work shifts to 10 hours in
duration, including 8 hours working outdoors and 2 hours of time spent at lunch, breaks, and travel.
Refer to Section 5.15, Cold Stress, fur further work day guidelines.
1.1.2 Short Service Employee
A Short Service Employee (SSE) is an employee with fewer than six months experience working
supervised on field projects or an employee who has not completed required training or received
required certifications.
Short Service Employees will not be assigned to work involving any machinery or equipment on this
project unless they are supervised on site by a qualified person.
1.2 Health and Safety Plan (HASP)
1.2.1 HASP Purpose
The purpose of this HASP is to identify hazards associated with this project and specify engineering
and administrative controls and personal protective equipment necessary to mitigate the risks
associated with these hazards. This HASP addresses the hazards recognized prior to writing or
updating the documents. As new hazards are encountered, a Job Hazard Assessment (JHA) or Job
Safety Analysis (JSA) must be conducted and the results input into the HASP.
This HASP also assigns responsibilities for the implementation of safety programs on this project and
defines monitoring and emergency response planning specific to the project.
AECOM Environment

1.2.2 HASP Applicability
This site-specific Health and Safety Plan (HASP) has been developed by AECOM. It establishes the
health and safety procedures required to minimize potential risk to AECOM and contractor personnel
involved with the field activities associated with the execution of the 7-Eleven program contract.
The provisions of this plan apply to AECOM personnel who will potentially be exposed to safety and/or
health hazards related to activities described in Section 3.0 of this document.
Client, Subcontractor employees, and third party personnel performing work that potentially exposes
them to the chemical and physical hazards at the site are recommended to work under their own

2.0 INTRODUCTION
2.1 AECOM Environment Safety Policy
AECOM Environment (AECOM) is committed to providing our employees with a safe and healthy
work environment. It is not only our obligation to each other, but also a sound business practice to do
so. Work related injuries and illnesses cause needless pain and suffering, cost money, and adversely
affect our reputation with our clients. Every attempt shall be made to eliminate the possibility of injuries
and illnesses. No aspect of the company's activities, including expediency and cost, shall take
precedence over the health and safety of our employees.
2.1.1 Maximum Duration of the Work Day for Field Activities
An employee may not work a shift that exceeds 16 hours in duration. For the purpose of this policy,
the work shift includes time spent at lunch and on break. If an employee works more than one shift
during the course of a calendar day, the total number of hours worked in that day cannot exceed 16
hours. Exception: If work is to be done continuously in ambient air temperatures of less than 20º F,
the Site Safety Officer and Field Manager will use a guideline of limiting work shifts to 10 hours in
duration, including 8 hours working outdoors and 2 hours of time spent at lunch, breaks, and travel.

4.0 Chemical Hazard Assessment and Control
4.1 Chemical Contaminants of Concern
4.1.1 BTEX
Petroleum is a highly complex mixture of aliphatic and aromatic hydrocarbons. Benzene, toluene,
ethylbenzene, and xylenes are natural but minor components of fuel oils, kerosene and diesel fuels.
Gasoline contains higher quantities of these aromatic hydrocarbons.
Exposure to the vapors of BTEX above their respective permissible exposure limits (PELs) as an 8-hr
time weighted average (TWA) may produce irritation of the mucous membranes of the upper
respiratory tract, nose and mouth. Overexposure may also result in the depression of the central
nervous system. Symptoms of such exposure include drowsiness, headache, fatigue and euphoria.
Chronic and prolonged overexposure to the vapors of benzene may cause damage to the blood-
forming organs and is known to cause leukemia in humans.
Gasoline is typically 1 – 2% benzene. The PEL for benzene is 1 ppm. The ACGIH has set a TLV for
Benzene at 0.5 ppm; however, for this project the SSO will use the OSHA PEL’s and will utilize an
action level of one half the PEL for various responses. Benzene is considered to be a carcinogen by
the ACGIH.
The PELs for ethylbenzene and xylene are 100 ppm. The PEL for toluene is 200 ppm. The American
Conference of Governmental Industrial Hygienists (ACGIH) have recommended a threshold limit
value of 50 ppm for toluene.
4.1.2 Petroleum Hydrocarbons
Petroleum hydrocarbons are generally considered to be of moderate to low toxicity. Federal or
recommended airborne exposure limits have not been established for the vapors of petroleum
hydrocarbons. However, inhalation of low concentrations of the vapor may cause mucous membrane
irritation. Inhalation of high concentrations of the vapor (which would only be likely to occur in
confined spaces where the liquid had been significantly heated) may cause extensive pulmonary
edema. Chronic direct skin contact with the liquid may produce skin irritation as a result of defatting.
4.1.3 Volatile Organic Compounds (VOCs & SVOCs)
Volatile Organic Compounds refer to a group of volatile compounds or mixtures that are relatively

VOCs are typically organic solvents used for extracting, dissolving, or suspending materials such as
fats, waxes, and resins that are not soluble in water. The removal of the solvent from a solution
permits the recovery of the solute intact with its original properties. Solvents are used in paints,
adhesives, glues coatings, and degreasing/ cleaning agents.
Semivolatile Organic Compounds (SVOCs) are less volatile chemicals that tend to persist in the
environment.
AECOM Environment
May 20121

4-2
Inhalation and skin absorption are the primary routes of exposure. Organic compounds are
metabolized or they accumulate in the lipid-rich tissues such as the liver, fat cells, or the nervous
system.
Solvent inhalation by workers can cause effects ranging from an alcohol-like intoxication to narcosis
and death from respiratory failure. Symptoms of solvent inhalation include drowsiness, headache,
dizziness, dyspepsia, and nausea.
4.1.4 Tetraethyl Lead
Tetraethyl lead (also called alkyl lead), was used as anti-knock agents in gasoline. Tetraethyl lead is
colorless liquid (unless dyed red, orange, or blue) with a pleasant, sweet odor. Tetraethyl lead
exposure can occur through inhalation, eye or skin contact, and absorption through the skin.
Exposure to tetraethyl lead through inhalation and skin absorption can induces sneezing, irritation of
the upper respiratory tract and mild to severe systemic responses: insomnia, lassitude (weakness,
exhaustion), nausea, anxiety, tremors, bradycardia, hypotension, and hypothermia. The most severe
responses include complete disorientation with hallucinations, and facial contortions. Such episodes
may progress to maniacal and violent convulsive seizures which may terminate in coma and death.
Tetraethyl lead targets the central nervous system, heart kidneys and eyes.
In contact with the skin tetraethyl lead induces itching, burning and transient redness.
4.1.5 Methyl tert-butyl ether
Methyl tert-butyl ether (MTBE) is a flammable liquid with a distinctive, disagreeable odor. It is made
from blending chemicals such as isobutylene and methanol, and has been used since the 1980s as
an additive for unleaded gasoline to achieve more efficient burning. Direct contact with the liquid may
cause minor skin and eye irritation. Prolonged or repeated inhalation of MTBE vapor may cause
irritation of the respiratory tract as well as depression of the central nervous system. OSHA has not
established a PEL for MTBE. However, the ACGIH has established a TLV of 50 ppm, as an 8-hr
TWA.
4.1.6 Ethyl Alcohol
Gasoline stations are using 10% ethanol as a replacement for MTBE. Pure ethanol is irritating to the
eyes, skin and respiratory tract. Exposure may also result in headache, nervousness, dizziness,
fatigue, distorted perceptions, loss of motor coordination and hallucinations. Chronic and repeated
overexposures may cause skin de-fatting and dermatitis as well as somnolence and lack of
concentration. The OSHA PEL for ethanol is 1,000 ppm, as an 8-hr TWA.
4.1.7 Dust
Dust generated during coring or cutting of concrete, boring, or excavations can be hazardous to the
respiratory system and irritating to the eyes. Dust can also carry the contaminants of concern
potentially exposing workers by skin contact and inhalation. The ACGIH has established an eight-hour
exposure limit for dust at 3 mg/m3. The concentrations of the chemicals of concern in the soil are low
enough that inhalation of dust would not by itself be an exposure hazard. However contamination of
skin and clothing can provide additional exposures. Therefore the generation and contact with dust
should be minimized.
AECOM Environment
May 20121

4-3
Water or other methods should be used to control dust during dusty operations; however care must be
used to prevent electrical shock if electric tools are used in the same area. If dusts become irritating
and engineering controls such as the application of water cannot be used, respirators should be
donned as discussed in Section 7.
4.2 Hazard Substances Brought On Site by AECOM
A material safety data sheet (MSDS) must be available for each hazardous substance that AECOM or
its contractors bring on the property. This includes solutions/chemicals that will be used to
decontaminate sampling equipment and gases needed to calibrate air monitoring equipment.
In addition, all containers of hazardous materials must be labeled in accordance with OSHA's Hazard
Communication Standard. Either the original manufacturer’s label or an NFPA 704M label specific for
the material (as shown at the right) is considered to be an acceptable label.
4.3 Chemical Exposure and Control
4.3.1 Chemical Exposure Potential
Employees can be exposed by inhalation to the chemicals of concern during the installation of the soil
borings, sampling activities or during O&M activities. Another route of potential exposure to the
contaminants of concern is via direct dermal contact with soils and groundwater during sampling.
Although highly unlikely, exposure to all of the contaminants of concern can occur via ingestion (hand-
to-mouth transfer). The decontamination procedures described in Section 9.0 address personal
hygiene issues that will limit the potential for contaminant ingestion.
4.3.2 Chemical Hazard Control
The chemical hazards associated with the investigative and sampling activities can be controlled in
several ways, including:
AECOM will perform air monitoring (Section 6) in the worker's breathing zone to determine exposure
to the chemicals of concern during the installation of soil borings and the sampling program. If
exposures exceed the action levels, respiratory protection as discussed in Section 7, will be donned.
To avoid direct dermal contact with contaminated media, protective clothing, as described in Section 7
will be required when collecting samples and decontaminating sampling equipment.
To avoid inhalation of vapors or dust during: sampling activities, drilling vacuum extraction of wells,
and excavation field personal should maintain a position up wind from the source of contaminants of
concern.
4.4 Hazardous Waste Management
Waste generated as a result of O&M or investigation activities will be containerized local to the point of
generation, sampled for characterization purposes and secured prior to off-site transportation and
disposal. Upon receipt of analytical results, the AECOM project team will work with the Client to
properly characterize, profile and dispose of the waste(s).

5.0 Physical Hazards and Controls
5.1 Back Safety
Using the proper techniques to lift and move heavy pieces of equipment is important to reduce the
potential for back injury. The following precautions should be implemented when lifting or moving
heavy objects:
Bend at the knees, not the waist. Let your legs do the lifting;
Do not twist while lifting;
Bring the load as close to you as possible before lifting;
Be sure the path you are taking while carrying a heavy object is free of obstructions and slip,
trip and fall hazards;
Use mechanical devices to move objects that are too heavy to be moved manually; and,
If mechanical devices are not available, ask another person to assist you.
5.2 Control of Hazardous Energy (Lockout)
Lockout procedures of control of hazardous energy shall be implemented and enforced. Lockout
procedures are required to render inoperative electrical systems, pumps, construction equipment,
motors, pipelines, valves and all other such energy systems that may accidentally be energized while
employees are working on them on or before they are ready and released for service. Control of
hazardous energy shall comply with Subpart J of 29 CFR 1910.
5.2.1 Basic Lockout Requirements
Notify affected personnel and facility staff;
Shut down equipment by normal stopping procedure;
De-activate the energy isolating device(s) so that the machine or equipment is isolated from
the energy source(s);
Apply locks with tag identifying the person performing the lockout. Each authorized person
working on equipment applies his/her own lock;
Release any stored energy;
Ensure that the equipment is disconnected from the energy source(s) by first checking that no
personnel are exposed, then verify the isolation of the equipment by operating the push
button or other normal operating control(s) or by testing to make certain the equipment will not
operate;
Remove guards or covers as necessary and perform work;
When work is complete, reinstall guards and inspect equipment to ensure it is operational;
Notify affected personnel;
AECOM Environment
May 20121

5-2
Remove locks. Each authorized individual removes his/her own; and
Return the equipment to service and notify affected personnel.
5.3 Concrete and Asphalt Coring & Cutting
Cutting and coring concrete and asphalt can involve numerous hazards. The noise generated as a
result of the tools used, and adequate hearing protection is necessary when conditions outlined in the
Noise section below are encountered. Tools used which can include drills and saws, must be
appropriately guarded to prevent hands, PPE, and other objects from being caught-up in the moving
parts and drawing employees in. Dust may also be generated while cutting concrete and either
respiratory protection or dust suppression will need to be utilized to prevent exposure. Additional
consideration must be given chemical hazard concerns that may exist in the materials underlying the
concrete.
5.4 Corrosive Liquids
Site activities may require the use of corrosive liquids for preserving samples once collected,
identifying substances in the field, or as part of system operations and maintenance. When corrosive
liquids are identified in the work area, PPE upgrades will need to include an appropriate glove to
mitigate the hazard, protective eye wear to guard against splashing liquids, and the potential need for
poly-coated Tyvek to be worn. Additionally, the job task will be analyzed to determine if splashing and
spilling can be minimized through the use of special equipment or procedures. Examples include
using a funnel, identifying an alternative substance for use, and more.
5.5 Cuts and Lacerations
Geoprobe soil samples are collected in acetate liners that must be cut open in order to collect the
sample. Additionally, tubing will need to be cut to facilitate groundwater sampling. Additional tasks for
the job may also pose laceration hazards. Tube-cutters are available and should be used to eliminate
this hazard. However, if it is necessary to use knives or blades, follow the safety precautions listed
below:
Keep your free hand out of the way;
Secure the acetate liner so it won't roll or move while you are cutting;
Use only sharp blades; dull blades require more force which results in less knife control;
Pull the knife at an angle to your body; pulling motions are easier to manage;
Don't put your knife in your pocket;
Use a hooked knife (i.e. linoleum knife) or a utility knife with a self-retracting blade; and
Wear leather or Kevlar® gloves when using knives or blades.
5.6 Drilling Hazards
Use of a drill rig to advance soil borings and install monitoring wells will require all personnel in the
vicinity of the operating rig to wear steel-toed boots, hard hats, hearing protection and safety eyewear.
Personnel shall not remain in the vicinity of operating equipment unless it is required for their work
responsibilities.
AECOM Environment
May 20121

5-3
Additionally, the following safety requirements must be adhered to:
All drill rigs and other machinery with exposed moving parts must be equipped with an
operational emergency stop device. Drillers and geologists must be aware of the location of
this device. This device must be tested prior to job initiation and periodically thereafter. The
driller and helper shall not simultaneously handle augers unless there is a standby person to
activate the emergency stop.
The driller must never leave the controls while the tools are rotating unless all personnel are
kept clear of rotating equipment.
A long-handled shovel or equivalent must be used to clear drill cuttings away from the hole
and from rotating tools. Hands and/or feet are not to be used for this purpose.
A remote sampling device must be used to sample drill cuttings if the tools are rotating or if
the tools are readily capable of rotating. Samplers must not reach into or near the rotating
equipment. If personnel must work near any tools, which could rotate, the driller must shut
down the rig prior to initiating such work.
Drillers, Driller’s helpers and geologists must secure all loose clothing, long hair, or jewelry
when in the vicinity of drilling operations.
Only equipment, that has been approved by the manufacturer, may be used in conjunction
with drilling equipment Pins that protrude excessively from augers shall not be allowed
No person shall climb the drill mast while tools are rotating.
No person shall climb beyond 6 feet above ground on the drill mast without the use of ANSI-
approved fall protection (approved belts, lanyards and a fall protection slide rail) or portable
ladder that meets the requirements of OSHA standards.
When using the rig’s hoist to lift or move objects other than the equipment associated with the
direct push operation, an assessment of the force required to perform the lift and the rig’s
design specifications must be made to determine whether the lift can be made safely. In all
cases personnel must not be in line with the cable when it is under tension.
If drilling operations are to be performed within an enclosed space proper procedures must be
followed to prevent the accumulation of carbon monoxide within the work area.
Open doors and windows and provide ventilation to the outside.
Employ the use of a mechanical ventilation system, i.e. blower or fan, appropriately sized for
the room to circulate fresh air.
Connect equipment exhaust points to hoses that can be direct ventilated to an outside area.
5.6.1 Rotating Parts
Exposure to rotating parts can occur when working near the drilling rig or the internal combustion
engine. All rotating parts should be covered with guards to prevent access by workers. When
performing maintenance activities that require the rotating parts to be exposed, workers should not
allow loose clothing, hands, or tools to approach the rotating parts. Guards must be replaced as soon
as possible after completing the maintenance task.
AECOM Environment
May 20121

5-4
Operation of drilling equipment also creates hazards associated with pinch points and rotating
equipment. Employees will evaluate work procedures to avoid placing their body and extremities in
the path of rotating equipment and tools to avoid being struck by moving equipment, tools and
machinery. Similarly, these hazards also create pinch point hazards where the body and extremities,
especially the hands, can be caught in moving equipment and crushed. Employees will evaluate
equipment and tool use procedures to identify pinch points and develop procedures to avoid placing
body parts in a position where they can be caught in moving equipment, tools and machinery.
5.6.2 Direct Push Hazards
Use of the Direct Push System to advance soil borings and collect soil samples will require all
personnel in the vicinity of the operating unit to wear steel-toed boots, hardhats, hearing protection
and safety eyewear. Personnel shall not remain in the vicinity of operating equipment unless it is
required for their work responsibilities. Additionally, the following safety requirements must be adhered
to:
A remote vehicle ignition is located on the control panel of the Geoprobe unit. This allows the
operator to start and stop the vehicle engine from the rear. This device must be tested prior to
job initiation and periodically thereafter. All employees should be aware of how to access and
operate the rear ignition.
The driller must never leave the controls while the probe is being driven.
Drillers, helpers and geologists must secure all loose clothing when in the vicinity of drilling
operations.
The Geoprobe vehicle shall not be moved any distance with the probe in the extended
position. Check for clearance at roof or the vehicle before folding the Geoprobe out of the
carrier vehicle.
Be sure the parking brake is set, or vehicle wheels have been chocked, before probing.
Never allow the derrick foot to be lifted more than 6" off of the ground surface.
Deactivate hydraulics when adding or removing probe rods, anvils or any tool in the hammer.
Verify that all threaded parts are completely threaded together before probing.
5.6.3 Sonic Drilling
Use of a Sonic Drill Rig to advance soil borings, collect soil samples and/or install monitoring wells will
require all personnel in the vicinity of the operating unit to wear steel-toed boots, hardhats, hearing
protection and safety eyewear. Personnel shall not remain in the vicinity of operating equipment
unless it is required for their work responsibilities. Additionally, the following safety requirements must
be adhered to:
A remote vehicle ignition may be located on the control panel of the Drill Rig. This allows the
operator to start and stop the vehicle engine from the rear. This device must be tested prior to
job initiation and periodically thereafter. All employees should be aware of how to access and
operate the rear ignition.
The driller must never leave the controls while the probe is being driven.

Drillers, helpers and geologists must secure all loose clothing when in the vicinity of drilling
operations.
The Drill Rig shall not be moved any distance with the mast in the extended position. Check
for clearance at roof or the vehicle before folding the Rig out of the carrier vehicle.
Be sure the parking brake is set, vehicle wheels have been chocked and/or outrigger
stabilizers have been positioned before drilling.
Never allow the derrick foot to be lifted more than 6" off of the ground surface.
Deactivate hydraulics when adding or removing rods, anvils or any tool in the hammer.
Verify that all threaded parts are completely threaded together before drilling.
5.7 Driving Safety
Drivers must be licensed to drive the class of vehicle they are operating and trained in defensive
driving. Only AECOM personnel may drive AECOM vehicles or vehicles rented for AECOM business;
client, subcontractor, or other work-related personnel may ride. Drivers and passengers must comply
with all traffic laws and posted signs, and will not operate a vehicle if under the influence of impairing
medication, alcohol, or any other substance.
Make sure that the following basic safe driving practices are followed at all times while working on this
project:
Always wear a seat belt while operating a motor vehicle or while traveling as a passenger.
Obey speed limits and local traffic laws at all times.
Obtain proper directions to the site in advance and take the route that is most likely to be free
of known traffic hazards (e.g., congestion, construction, etc.) and that avoids travel through
potentially dangerous neighborhoods.
Abstain from distractions while driving (e.g., the use of cell phones, eating/drinking, reading
maps, etc). While on company business, drivers are prohibited from using hand-held mobile
phones and “texting” while operating a motor vehicle. If drivers require use of such devices,
they shall drive to a safe location where they can park to perform these activities. The only
exception to this prohibition is with the use of a “hands-free” cell phone where local laws allow
for such use and where weather and traffic conditions permit. In general, it is AECOM’s policy
to discourage use of all two-way communication devices while operating motor vehicles. Do
NOT allow other distractions to interfere with your safe operation of the vehicle.
Do not operate a motor vehicle if you are tired and/or have not had sufficient rest. AECOM’s
H&S policy 1.2 limits the maximum length of the workday to 16 hours for fieldwork. This limit
includes the time spent driving to/from a site.
All unattended personnel transport vehicles will not be allowed to idle, and must be turned off
when not in use.
AECOM Environment
May 20121

5.7.1 Planning / Preparation
Prior to departure, check traffic reports, weather conditions, road construction, and road
closures. If necessary, develop an alternate route and new, approved JMP (Journey
Management Plan).
Prior to entering the vehicle, inspect the vehicle.
Leave early to allow for contingencies.
5.7.2 DOT
If you are to operate a vehicle exceeding 10,000 pounds (or vehicle and trailer with a combined weight
over 10,000 pounds), or you are to transport greater than 1,000 pounds of hazardous materials, you
MUST comply with DOT regulations. These are NOT addressed in this HASP; contact the H&S
Department if this applies.
5.7.3 Secure Packing
Do not move your vehicle unless all equipment and supplies are secured. Items and material which
may roll, slide, or move about in your vehicle while traveling are a major hazard. Secure the load!
5.7.4 Emergency Procedures
Always move out of traffic if possible; even if those in front of you have stopped. Stopping on an active
highway can precipitate being hit from the rear. If you must stop on an active roadway, leave at least
one car length in front of you, and watch the rear mirror, so you can ease up if someone behind can’t
stop. Keep your flashers on in this situation. If you are the only driver coming to a stop on an active
roadway, leave the flashers on and when safe to do so, exit the car and get to a safe location.
If you must stop due to vehicle failure, etc. try to coast out of traffic. Put on your flashers, and tie a
white handkerchief, etc. on the driver’s side door or mirror. If you remain in the vehicle, lock the
doors. Use your cell phone to summon help.
5.8 Electrical Hazards
Only qualified electricians with full knowledge of the electrical code requirements will be allowed to
perform electrical work. Electrical tools and equipment must be grounded, of the double insulated type
or battery operated. The use ground-fault circuit interrupters (GFCIs) are required. Additionally,
inspection and testing shall be conducted to locate defective electrical equipment, tools, and cords,
which may expose personnel to electrical hazards.
Temporary electrical cords are rated for extra hard usage or hard usage and are the three-wire type
with a grounding pin and a grounding receptacle. Look for the following letters on the cord: S, SJ, ST,
or SO. No Romex, ribbon or two-wire extension cords Temporary electrical cords must be protected or
elevated a minimum of 8 feet. They must be kept clear of walkways and other location where they
may be exposed to damage or create a trip hazard. Do not hang extension cords with bare wire, nails,
staples or objects that will cut/damage cords. Inspect all electrical cords for signs of wear and exposed
wiring, strain, and ripped, torn, cut or burned insulation. Defective cords shall be removed from
service.
AECOM Environment
May 20121

5-7
Prior to digging or boring check the work area for overhead and underground electrical utilities. If the
overhead power line is 50 kV or less, then stay at least 10 feet away. For everything else, keep at
least 35 feet away. Contact the power company if power lines needed to be, moved, de-energized
and grounded, or have insulated sleeves installed.
When work is to be performed on electrical equipment, lockout procedures are required to ensure that
the equipment is de-energized and isolated.
5.9 Excavation and Trenching
AECOM field personnel shall not enter any trench or excavation that they feel is not safe or meets the
minimum requirements found in this section. As an alternative to entering an excavation for sample
collection, an excavator can scoop up a load of soil from the desired location and the soil sample can
be taken from the bucket.
Excavating and trenching operations shall be performed in such a manner as to protect personnel
from the dangers associated with trenching and excavating such as cave-ins, and to prevent damage
to underground utilities.
A competent person will conduct daily inspection of each trench or excavation, the adjacent hazards
and protective systems for evidence of possible cave-in/failure of protective systems, hazardous
atmosphere, and other hazardous condition and determine the necessary precautions to take. In
addition, the competent person shall perform soil classification in accordance with Subpart P of 29
CFR 1926. The inspections shall be documented.
Prior to digging, all underground utilities in the work area must be positively identified has indicated in
Section 5.24. Markings made during the utility investigation must be maintained throughout the course
of work. If underground utilities not previously identified are encountered, work shall be immediately
ceased and the Project Manager will be notified before proceeding.
A means of safe access and egress (ladders, steps, ramps) to all excavations must be
available when trench excavations are 4 feet or deeper and located so as to require no more
than 25 feet of lateral travel. Ladders must extend at least 3 feet above the edge of the trench
and be securely staked in place.
Walkways or bridges with standard railings and toeplates must be provided when personnel
or equipment are required to cross over excavations.
The walls and faces of all excavations in which personnel are exposed to danger from moving
ground must be guarded by a shoring system, sloping of the ground, or some other
equivalent means.
No person shall be permitted under loads handled by excavator, loader, backhoe etc.
The spoils pile must be placed at one side of the excavation. At a minimum, the toe of the
spoil pile shall be at least 2 feet away from the edge of the excavation. The spoils pile shall be
moved farther back in proportion to the depth of the excavation. The spoils pile height shall
not exceed the depth of the excavation and shall be sloped to prevent the soil and rocks from
sliding into the excavation.
All wells, holes, test pits, shafts, etc., shall be barricaded or covered. Covers shall be secured
in place and marked.
AECOM Environment
May 20121

5-8
Do not enter an unprotected trench! Trenches 5 feet deep or greater require a protective
system unless the excavation is made entirely in stable rock. Trenches 20 feet deep or
greater require that the protective system be de-signed by a registered professional engineer
or be based on tabulated data prepared and/ or approved by a registered professional
engineer Protective system(s) to prevent cave-in shall be used when personnel enter
excavations.
Where protective systems are used such as trench boxes, hydraulic shoring, etc., they shall
be used in accordance with the manufacturer's specifications and limitations. The
manufacturer's tabulated data for such systems will be maintained on the project site.
Excavations or trenches which water is free flowing into or has accumulated shall not be
entered until water removal is initiated and maintain to prevent cave-in or engulfment.
5.10 Flammable Vapors/Liquids
Petroleum hydrocarbons vapors are all heavier than air and settle close to the ground and into low
laying areas. Gasoline vapors have a very low flash point and are more flammable then diesel fuel or
kerosene vapors. Nevertheless, vapors of all petroleum hydrocarbons should be consider flammable.
During subsurface drilling or tank removal pockets of petroleum hydrocarbons may be encountered.
Vapors of petroleum hydrocarbons between their lower explosive limit (LEL) and upper explosive level
(UEL) may migrate into the borehole or excavation and flashover when spark is introduced. The vapor
in the borehole or excavation can be monitored using the PID. The chart below can be used to
determine if the atmosphere is at or above the action limit of 10 % of the LEL.
Chemical Name LEL (ppm) 10% of the LEL
(ppm)
Benzene 12000 1200
Toluene 11000 1100
Ethyl Benzene 8000 800
Xylene 11000 1100
Gasoline 14000 1400
Diesel Fuel 6000 600
Kerosene 7000 700

Concentrations of gases and vapors at or above the LEL are also considered immediately dangerous
to life and health (IDLH) atmospheres and should not be entered.
If the borehole or excavation flashes over and a fire remains burning or equipment is on fire, field
personal should not attempt to extinguish the fire but should call 911 to report the fire. Field personal
must evacuate the area and get others out of harm’s way.
The performance of hot work or the use of electrical equipment which has not been approved for use
in hazardous locations is prohibited in areas where the concentration of flammable gases and vapors
is in excess of 10% of the lower explosive limit (LEL).
AECOM Environment
May 20121

5-9
Equipment used in hazardous locations must meet the National Electrical Code (NEC) classification
for hazardous locations.
Class 1, Division 1 locations are ones in which flammable concentrations of gases or vapors
exist (1)continuously, intermittently or periodically under normal operating conditions or (2)
frequently because of maintenance or repair operations or because of leakage.
Class 1, Division 2 locations are ones (1) in which flammable liquids or gases are handled but
are normally confined within closed containers or systems, (2) in which flammable
concentrations of gases or vapors are prevented by positive mechanical ventilation, or (3) are
adjacent to, but not physically isolated from, Class I, Division I locations.
When free product is being transferred from a recovery well or tank to a vacuum truck or container,
electrical bonding of the containers must be established to prevent a static spark. In addition the
container must be grounded.
5.11 Flying Objects Hazards
Activities involving the use of power tools, drilling rigs, and hand tools, among other activities, can
create flying object hazards where objects can become projectiles. When flying objects represent
projectiles employees need to use equipment that is appropriately guarded to minimize the creation of
projectile hazards, and also use the appropriate PPE including hard hats, safety goggles, face shields
to prevent projectiles from causing injuries to employees.
5.12 Hand Augering
In addition to the precautions listed in the Back Safety discussion below, additional care should be
taken to prevent injuries when using hand augers.
When practical, work as a team of two to advance borings with a hand auger.
Wear cotton or leather gloves when rotating the auger.
Avoid putting pressure on the palms of your hands; use a good grip to spread the pressure
over the entire hand.
Take frequent stretch breaks to stretch and relax your back, arms and hands.
5.13 Hand Safety
5.13.1 Glove Selection
To protect onsite workers from hand injuries, the following gloves will be used for when performing a
specific duty:
Brightly colored gloves will be used to help emphasize and easily locate the hands. It is
recommended that the color of gloves be changed monthly to draw attention to the hands.
Pinch points are found between a moving object and a stationary object, or between two continuously
moving objects. Yellow hand stickers will be placed on equipment to remind workers of pinch points.
AECOM Environment

5.13.2 Working with Glassware
Glass bottles, laboratory equipment, and VOA vials can break and cause lacerations and puncture
wounds. The follow preventive measures should be taken to reduce the potential for broken
glassware.
Package all glassware such that there is no glass to glass contact during transportation or
storage;
Assume that any time glass strikes another object it is damaged;
Inspect all glassware for cracks, scratches, and other damage before using;
Lids and caps should be “finger tight” unless there is a torque specification and you use a
torque wrench;
Never fill a glass container (other than VOA vials with a septum) liquid full, always leave an air
space to buffer thermal expansion of the liquid; and
Avoid rapid temperature changes when filling glass containers.
Glass often has flaws that cannot be detected by visual inspection and the force needed to
open and tighten lids can cause these flaws to fracture the glass. Any time force is applied to
glass, workers should wear leather gloves or preferably Kevlar® gloves to protect against
breakage and injury. Kevlar® glove liners are available for use under Nitrile or cotton gloves.
5.13.3 Hand Tools
Rules for the safe use of hand tools:
Select the right size tool for the job. Don’t use “cheaters” and avoid pulling old tools from the
waste stream. There’s a reason why they were thrown away!
All hand tools must be in safe condition.
Handles must be sound, straight and tight-fitting.
Always inspect tools before use and replace or repair worn or damaged tools.
Always keep the cutting edges sharp and never test a cutting edge with your finger.
When working on an elevated surface (ladder, truck, scaffold), ensure your tools are secure.
Falling tools can cause serious injury.
Always carry your tools correctly and never put sharp or pointed tools in your pocket.
When carrying hand tools, always point the cutting edge to the ground.
Always keep your tools in a dry place to prevent rust.
Cutting tools must be kept sharp and properly shaped.
Secure work pieces prior to cutting or drilling.
Keep the unused hand and other people away from the tool.
AECOM Environment
May 20121

5-11
5.13.4 Specific Tool Use
5.13.4.1 Screwdrivers
Most screwdrivers are not designed to be used on electrical equipment. Use an insulated screwdriver
for electrical work.
Do not hold an object in the palm of one hand and press a screwdriver into it; place the object on a
bench or table. Never hammer with a screwdriver. Never use a screwdriver with a broken handle,
bent or burred blade, etc.
5.13.4.2 Pliers
Do not use pliers as a substitute for hammers, wrenches, pry bars, etc. Use insulated pliers when
doing electrical work. Inspect the pliers frequently to make certain that they are free of breaks or
cracks.
Use the right type of pliers for the specific task – adjustable, locking (Vise Grip®), standard, bolt size
fit, pipe wrench.
5.13.4.3 Hammers
Use the correct hammer for the specific type of striking work (task) to be done. Always wear safety
glasses when using a hammer to strike an object. Always use the claw portion of a hammer to remove
nails and not as a pick or awl. Have an unobstructed view and swing when using a hammer. Watch for
overhead interference on back and forward swing. Use a good grip and use something other then
your hand to hold a nail when starting hammering. Check for defects on the handle and head before
using. If the hammer head shows signs of mushrooming, replace it immediately.
Handles may be wood, tubular/solid steel or fiberglass. Replace any hammer with a loose handle
before the head flies off and causes injury to you or someone else. Tighten loose handles with the
proper wedges; never use nails or staples for wedges. If a steel or fiberglass handle is loose replace
it, since it is more difficult to repair than a wooden one. Some fiberglass handles can be tightened with
the aid of a repair kit with epoxy materials.
5.13.4.4 Wrenches
Select the correct size of wrench for the job. Never use a pipe wrench as a wrench handle extension.
Too much leverage can ruin a tool and cause injury.
To avoid sudden slips, stand in a balanced position and always pull on the wrench instead of pushing
against the fixed jaw, particularly when a pinch point is created. Wear gloves when using a wrench in
a confined space.
Whenever possible use a box end wrench instead of an open end wrench to avoid slipping.
5.13.4.5 Chisels
Always wear safety goggles or a face shield when using a chisel. Drive chisels outward and away
from your body. Do not use chisels to pry. Keep edges sharp for most effective work and protect
AECOM Environment
May 20121

5-12
when not in use. Driven tools (chisels, punches, etc.) must be dressed to remove any mushrooming.
Use the proper hammer when using a chisel.
5.13.4.6 Knives
Always perform a thorough Job Safety Analysis (JSA) to define the proper cutting tool for the task.
Always place the item to be cut on a solid surface, attempt to hold the cut item without your hand and
cut in a direction away from the body and hand.
Always keep hands and body clear of the knife stroke. Always keep the cutting tool blades sharp.
Make sure there is plenty of open space around you when using any cutting tool.
Use the following safer tools in place of fixed open blade knives (FOBK) whenever possible:
Self-retracting utility knives
Guarded utility knives
Shears, snips, and/or scissors
Concealed blade cutters
Pipe cutters
Specialty cutters (e.g. Geoprobe Acetate Liner Cutter)
Ratcheting tools
5.14 Heavy Equipment
The use of heavy equipment for earth moving work poses potential hazards to employees. Such
equipment can cause trauma injuries to the operator or nearby workers. It may also roll over, or fall on
sloped ground or unstable soil. AECOM personnel are to remain clear of operating heavy equipment
to the extent feasible.
Operators of earth moving equipment must be experienced or trained in the use of the equipment.
They must inspect the equipment each day before use to assure that it is in safe operational condition.
The equipment must be set up in a stable configuration, with the outriggers fully extended and
supported on stable soil to prevent rollover. The rear swing-radius must be barricaded to prevent
injuries to persons passing behind the equipment.
When employees must work near the equipment, eye contact and clear communication must be
maintained.
5.15 Heavy Equipment – Drill Rigs
Drill rigs are considered to be heavy equipment, and therefore precautions must be incorporated into
job activities when working in close proximity to drill rigs. In addition the wearing the PPE that has
been determined to be necessary for the project, employees will need to ensure that Drill Rig
Operators conduct inspections of the drill rig on a daily basis. A drill rig inspection is included in
Attachment C as a reference. Focal points of the inspection should include checking hydraulic lines,

tools and drilling equipment, emergency stop switches, and other parts of the equipment to insure that
they are maintained in a safe operating condition.
Employees will also consider the staging their work area so that they are not within the shadow of the
drill rig’s mast. Working within this area creates a potential to be contacted by the drill rig if it were to
tip over on its side. Likewise, when establishing a drilling location, the rig shall be positioned so that it
won’t clip overhead power lines should it tip over.
5.15.1 Heavy Equipment-Earthmovers
Employees working around heavy equipment such as backhoes, excavators, loads and dump trucks
take precaution to prevent being struck by equipment. Hard hat and a high visibility traffic safety vest
must be worn when working around equipment. Field team members must be alert for the sudden
movement of equipment and never walk behind or long side moving equipment. If you cannot see the
operator, the operator cannot see you. If you have to cross in front of equipment maintain eye contact
with the operator and wait until they signal you to cross or approach the machine. Do not stand next to
or near equipment being loaded or unloaded. Hitching or riding on equipment in other than the
operator’s seat is prohibited. Employees should not use personal head stereo sets, talk on cell
phones or text message when working near heavy equipment.
5.16 Insects, Spiders, Wasps and Bees
Employees are encouraged to review AECOM SHE SOP 610 – Biological Hazards Injury & Illness
Prevention, for detailed discussion on working around insects within the workplace and procedures
that can be used to minimize and prevent exposure.
5.16.1 Ticks
Ticks are bloodsuckers, attaching themselves to warm-blooded vertebrates to feed. Deer ticks are the
most common carriers of Lyme disease, a bacterial infection that is transmitted to humans through the
bite of the tick.
Personnel should carefully inspect themselves each day for the presence of ticks or any rashes. This
is important since prompt removal of the tick can prevent disease transmission. Female deer ticks are
about one-quarter inch in length and are black and brick red in color. Males are smaller and all black.
Removal of the tick is important in that the tick should not be crushed and care must be taken so that
the head is also removed. If the head is not completely removed or if the tick is allowed to remain for
days feeding on human blood, a condition known as tick paralysis can develop, this is due to a
neurotoxin that the tick apparently injects while engorging. This neurotoxin acts upon the spinal cord
causing loss of coordination, weakness and paralysis.
One characteristic symptom of Lyme disease is a bulls-eye rash that develops around the bite site.
The rash appears in about 60-80% of all Lyme disease cases. Contact your OHSC immediately if you
develop such a rash.
Tick season typically lasts from April through October; peak season is May through July; seasons can
very depending on climate. Wear light-colored clothing (easier to spot ticks) with long sleeves and
make sure that shirts are tucked into pants and pants are tucked into socks or boots. Ticks have a
tendency to crawl upwards. These procedures will make it more difficult for a tick to reach your skin.

Studies have determined that repellants containing DEET as a main ingredient are most effective
against mosquitoes and ticks. DEET can be directly applied to the exposed skin of adults and/or
clothing. Products containing DEET can’t be used with Fire Resistant Clothing (FRC) as it diminishes
the garments’ capacity to resist ignition in a fire. Permethrin is another repellent; however, it can only
be directly applied to clothing.
5.16.2 Mosquitoes
Mosquitoes, carriers of the West Nile Virus, Yellow Fever and other diseases, are indigenous to the
area. As mentioned above, DEET is an effective mosquito repellent and is recommended. Although
concentrated DEET formulations protect longer than those that are more dilute, little improvement is
offered by concentrations of the active ingredient higher than 50 percent. Adverse effects, though
documented, are infrequent and are generally associated with gross overuse of the product. Users
should avoid the temptation to apply the most concentrated product available. The transient
protection offered by more dilute preparations can be extended by reapplication. When using DEET
care should be taken to reapply the repellant when its effectiveness wears off.
5.16.3 Spiders
Spiders and wasps may be found in derelict buildings, sheltered areas, and even on open ground.
Exercise care when collecting samples and avoid reaching into areas where visibility is limited. If
bitten by a spider, notify a co-worker or someone who can help if you should you have an allergic
reaction or develop other symptoms related to spider venom. Stay calm and treat the area with ice or
cold water. Seek medical attention if you have any reactions to the bite such as developing a rash,
excessive swelling or pain at the site of the bite or sting or any swelling or numbness beyond the site
of the bite.
Black Widow Spider
Abdomen usually shows hourglass marking.
The female is 3-4 centimeters in diameter.
Have been found in well casings and flush-mount covers.
Not aggressive, but more likely to bite if guarding eggs.
Light, local swelling and reddening of the bite are early signs
of a bite, followed by intense muscular pain, rigidity of the
abdomen and legs, difficulty breathing, and nausea.
If bitten, see physician as soon as possible.

AECOM Environment
May 20121

5-15
Brown Spiders (Recluse)
Central and South U.S., although in some other areas, as
well.
¼-to-½-inch-long body, and size of silver dollar.
Hide in baseboards, ceiling cracks, and undisturbed piles of
material.
Bite either may go unnoticed or may be followed by a severe
localized reaction, including scabbing, necrosis of
affected tissue, and very slow healing.
If bitten, see physician as soon as possible.

Studies have determined that repellants containing DEET as a main ingredient are most effective
against mosquitoes and ticks. DEET can be directly applied to the exposed skin of adults and/or
clothing. Products containing DEET can’t be used with Fire Resistant Clothing (FRC) as it diminishes
the garments’ capacity to resist ignition in a fire. Permethrin is another repellent; however, it can only
be directly applied to clothing.
5.16.4 Wasps and Bees
Wasps (hornets and yellow-jackets) and bees (honeybees and bumblebees) are common insects that
may pose a potential hazard to the field team if work is performed during spring, summer or fall. Bees
normally build their nests in the soil. However, they use other natural holes such as abandoned rodent
nests or tree hollows. Wasps make a football-shaped, paper-like nest either below or above the
ground. Yellow-jackets tend to build their nests in the ground but hornets tend to build their nests in
trees and shrubbery. Bees are generally more mild-mannered than wasps and are less likely to sting.
Bees can only sting once while wasps sting multiple times because their stinger is barbless. Wasps
sting when they feel threatened. By remaining calm and not annoying wasps by swatting, you lessen
the chance of being stung.
Wasps and bees inject a venomous fluid under the skin when they sting. The venom causes a painful
swelling that may last for several days. If the stinger is still present, carefully remove it with tweezers
or y scraping a credit card or other blunt object against the sting site in the opposite direction in which
the stinger is embedded. Some people may develop an allergic reaction, i.e. anaphylaxis, to a wasp or
bee sting. If such a reaction develops, seek medical attention at once. Persons who are allergic to
bee and wasp stings should carry an epinephrine pen, e.g. epi-pen, with them that is prescribed by a
doctor and used to help abate swelling that occurs due to their allergy. Even if an employee utilizes
their epi-pen, they still need to seek medical attention for follow-up care and observation.
5.17 Noise Exposure
The use of drilling equipment can expose the field team to noise levels that exceed the OSHA PEL of
90 dB for an 8-hour day. Exposure to noise can result in the following:
Temporary hearing losses where normal hearing returns after a rest period;
AECOM Environment
May 20121

5-16
Interference with speech communication and the perception of auditory signals;
Interference with the performance of complicated tasks; and,
Permanent hearing loss due to repeated exposure resulting in nerve destruction in the
hearing organ.
Since personal noise monitoring will not be conducted during the proposed activities, employees must
follow this general rule of thumb: If the noise levels are such that you must shout at someone two (2)
feet away from you, you need to be wearing hearing protection. Employees can wear either
disposable earplugs or earmuffs but all hearing protection must have a minimum noise reduction
rating (NRR) of 27 dB.
5.18 Overhead Materials
Overhead materials can include objects, tools, utilities, equipment and machinery that are, or have the
potential to be, elevated above the work area. Overhead materials pose a significant safety risk
because of the force that can be generated when they fall and strike an employee. Special attention
should be paid when setting up a work area to evaluate the potential for overhead materials to cause
traumatic blunt force trauma. Consideration must be given to potential for these overhead objects to
be contacted during the course of work by AECOM employees and Subcontractors, and what the
result of contacting these overhead materials will be.
If possible, the work area should be adjusted or moved so that no overhead materials present a
hazard. Likewise, if the object overhead can be relocated to remove the hazard, that is the preferred
course of mitigation. When the hazard can’t be eliminated, then protective measures to shield the
employees from being struck by falling objects should be taken. As a last resort, and as part of the
minimum PPE for site work, employees working in areas where falling objects pose a hazard will wear
a hard hat.
5.19 Pinch Points
The use of hand tools, mechanical equipment, heavy machinery and more can create pinch points
within the working area. Pinch points can be recognized when moving objects are present in the work
space in close proximity to employees, and it is reasonable to assume that a part of the employee’s
body can be caught between the moving objects. Pinch points will be considered when performing a
Job Safety Analysis for the task being performed and recommendations will be made to reduce the
potential for body parts to become caught in moving parts, including but not limited to:
The use of PPE, e.g. gloves, boots, etc, to protect exposed body parts;
Guarding machinery and equipment to prevent body parts from being caught in the moving
objects;
Using tools as an extension of the body to avoid placing body parts in the path of harm.
When tools are used as an extension of the body consideration will be given to how the tool
may become a hazard if it is caught within moving parts.

5.20 Poisonous Plants
Employees are encouraged to review AECOM SHE SOP 610 – Biological Hazards Injury & Illness
Prevention, for detailed discussion on working around poisonous plants within the workplace and
procedures that can be used to minimize and prevent exposure.
All undeveloped property potentially has poison ivy, oak, or sumac growing in areas where vegetation
is not controlled. These plants can also be found in cultivated and landscaped areas. Perform a
hazard analysis appropriate for the working conditions and consider the existence of poisonous
plants. Use appropriate PPE to prevent exposure, including but no limited to, full length clothing,
Tyvek coveralls, and dermal barrier creams.
Poison Ivy
Grows in West, Midwest, Texas, East.
Several forms – vine, trailing shrub, or shrub.
Three leaflets (can vary 3-9).
Leaves green in summer, red in fall.
Yellow or green flowers.
White berries.

Poison Oak
Grown in the East (NJ to Texas), Pacific Coast.
6-foot tall shrubs or long vines.
Oak-like leaves, clusters of three.
Yellow berries.

Poison Sumac
Grows in boggy areas, especially in the
Southwest and Northern states.
Shrub up to 15 feet tall.
Seven to 13 smooth-edged leaflets.
Glossy pale yellow or cream-colored berries.

If you must enter areas containing such plants, wear protective clothing, such as Tyvek® coveralls,
Nitrile or latex gloves, and boot covers. The use of a barrier cream such as Ivy Block can prevent the
AECOM Environment
May 20121

5-18
active agent in poisonous plants from affecting skin and Tecnu cleansing wipes can remove the plant
oil from exposed skin.
Avoid using mowers and weed trimmers in areas where poison ivy and oak are likely. Additional care
should be taken during early winter after the leaves have fallen from the poisonous plants; the poison
still exists in the vines and stubble remaining above the ground. Wash any contaminated skin
immediately with cold water and mild soap.
5.21 Slips, trips and fall hazards
On any work area, it is expected that the ground might be uneven. The ground surface might be
unreliable due to settling. Surface debris might be present and wet or swampy areas can exist.
Employees shall be vigilant in providing clear footing, clearly identifying obstructions, holes, or other
tripping hazards and maintaining an awareness of uneven terrain and slippery surfaces. Fall hazards
such as slips, trips and falls from elevations will be eliminated or guards will be erected around the
hazard.
Employees should walk around, not over or on top of debris or trash piles. When carrying equipment,
identify a path that is clear of any obstructions. It might be necessary to remove obstacles to create a
smooth, unobstructed access point to the work areas on site.
Makeshift substitute ladders such as toolboxes, buckets, and coolers shall not be used. The use of
cellular telephones (making or receiving calls) or texting should be avoided when walking.
During the winter months, snow shovels and salt crystals or calcium chloride should be kept on site to
keep work areas free of accumulated snow and ice. Furthermore, use sand or other aggregate
material to help keep work surfaces from being slippery, especially where salt/calcium chloride cannot
be used. In addition, make sure work boots have soles that provide good traction. When walking on
ice is necessary crampons or Yaktrax® should be used.
Maintaining a work environment that is free from accumulated debris is the key to preventing slip, trip
and fall hazards at construction sites. Essential elements of good housekeeping include
Orderly placement of materials, tools and equipment;
Placing trash receptacles at appropriate locations for the disposal of miscellaneous rubbish;
Prompt removal and secure storage of items that are not needed to perform the immediate
task at hand; and
Awareness on the part of all employees to walk around, not over or on, equipment that might
have been stored in the work area.
5.22 Splashing Liquids
Groundwater sampling activities can produce splashing hazards in the work area. Employees will use
techniques that minimize the production of splashing hazards while handling liquids, including
groundwater, sample container preservatives, decontamination solutions and any other liquids in the
work area. Employees will also evaluate the working tasks to consider the use of goggles while
working with liquids.
AECOM Environment

5.23 Traffic Safety
5.23.1 Basic Procedures
Heavy traffic in the parking areas and dispensing islands will be a concern to employees. The most
danger is associated with tasks, such as groundwater sampling, where large machinery is not needed
and employees are working low-to-the ground in a crouched position. To make certain that motorists
are aware of our presence, all employees who are potentially exposed to traffic hazards should wear
orange or yellow ANSI Class II or III safety vests. In accordance with AECOM Traffic Safety
Protocol for Non-Intrusive Task At Retail Petroleum Facilities Work as found in Attachment G, the
area should be delineated with traffic cones, or other suitable warning barriers, to prevent motorists
from inadvertently driving through. As for vests, cones or other barrier materials should be
reflectorized if work will be performed during dusk or evening hours.
At a minimum, the on-site field technician will be required to complete the following to address traffic
safety hazards when working at a retail facility:
Prior to the start of work, field staff will communicate with the store manager or employee to
let them know that you are on-site and the duration of your site work.
Secure approval for any disturbances or impact to facility operations that might be required to
complete the field task safely (shut-down of dispenser island, relocation of customer parking,
etc.). If you do not receive cooperation from the facility stop work and notify the Project
Manager.
Conduct a site survey and determine the order in which the wells should be sampled based
on your scope of work. Are there any obstacles on or near the wells? If so, can the obstacles
be removed safely (i.e. vehicle, dumpster, water, ice/snow, etc.).
When performing routine field tasks within paved parking areas, field staff will be required to
use a vehicle as a safety barrier. Activate hazard lights, back the vehicle as close to the work
area as possible. The front of the vehicle should be facing the heaviest flow of traffic. The
objective is to work out the back of the vehicle, with the vehicle between you and the flow of
traffic, thereby reducing exposure to traffic hazards.
At a minimum, your work area behind the vehicle should be 5 feet x 5 feet, this should
increase to 10 feet x 10 feet when working in the rain or snow. Safety gates with high visibility
flagging will be used to mark your work zone . Large cones with high visibility flagging can
only be used as an alternative to barriers as a last resort if barriers are not available.
When on the ground or bent-over working on a road box, your back should be facing the
vehicle. This approach allows you to be aware of your surroundings and offers protection for
you blind spot (behind you).
If your well or field task is in front of or immediately adjacent to a parking spot, block off the
entire parking location prior to starting your sampling/gauging activities (refer to Figure 1).
If you are sampling near a car, and are unsure about the competency of the driver or feel
unsafe, remove yourself from the area until the driver leaves, or the area is safe.
NOTE: If at any point, field staff do not feel that conditions are controlled enough to facilitate the safe
completion of a field task STOP WORK AND REEVAULATE.
AECOM Environment

5.23.2 Work On/Adjacent to Public Roadways
For projects that involve potential exposure to traffic on or adjacent to public roadways, consult the
"Work Zone Traffic Control" handbook, under "Traffic Control" on AECOM's H&S Website, at the
following web address: http://intranet.AECOM.com/healthweb
The handbook was developed by the State of Maine DOT and provides examples of traffic control
applications for typical road work situations (e.g., closure of one lane of a two lane road, stationary
work on the shoulder of a road, mobile work along the shoulder of a road, etc.). Although it was
written to reflect the basic requirements of Part VI of the Federal Highway Administration's (FHWA)
Manual of Uniform Traffic Control Devices (MUTCD), this handbook is not a regulatory document.
Since specific requirements will vary from state to state, and within a state, by county, city or town.
5.23.3 Flagging/Redirecting Traffic
Specific requirements exist when traffic must be redirected around a work area that is on or adjacent
to a public roadway. In certain locations only police officers may redirect traffic. As a minimum,
OSHA requires that flaggers be formally trained in accordance with the requirements specified in
ANSI D6.1-1971. As a result, AECOM personnel should not redirect traffic on public roadways.
http://www.atssa.com/cs/flagger
Texas Flagging Requirements:
Certification required every three years;
Hardhat required. DOT must wear white. Contractors wear any color;
Reflectorized safety vests required. and
All training courses handled by ATSSA and Texas Engineering Extension Services.
When traffic must be redirected, and the local police do not perform that role, a traffic control firm
should be hired (these are frequently listed in the yellow pages under "safety").
5.24 Utility Hazards
5.24.1 Underground Utilities
Federal and state law requires that a utility clearance be performed at least two (2) working days prior
to initiation of any subsurface work. The nation’s one call locating system can be accessed by calling
811.
To request a mark-out of natural gas, electric, telephone, cable television, water and sewer lines in the
proposed drilling locations. In many locations, a separate location request must be submitted to the
municipality providing potable water, sanitary and storm sewerage. Work will not begin until the
required utility clearances have been performed.
Utility clearance organizations typically do not mark-out underground utility lines that are located on
private property. As such, the drilling contractor must exercise due diligence and try to identify the
location of any private utilities on the property being investigated.
AECOM Environment
May 20121

5-21
In accordance with AECOM Subsurface Boring Clearance Procedures At Retail Petroleum Facilities
as found in Attachment G. At a minimum, prior to performing any subsurface assessment work, the
Project Manager will be required to do the following list of activities:
Request as-builts or other maps and information from the client concerning underground
utilities, USTs, piping, etc. related to the site.
If as-builts are not available or if there is no individuals on-site with knowledge of utility
locations the project manager will evaluate the additional step of contacting a private utility
clearing company.
Confirm that the field staff understands the types of known and potential underground and
above ground structures and their associated equipment.
Confirm that the field staff has conducted a site walkover to visually identify known or potential
structures or equipment (e.g. concrete pads, re-paved portions of the parking lot, etc.).
Confirm that the field staff has conducted a visual inspection of the site and has identified all
observable utilizes boxes, poles, manholes, etc. and has established obvious lines of
underground connections between two or more of these structures.
Confirm that the field staff understands the limits of the “UST equipment exclusion zone”,
which encompasses all components of the UST system (tanks, product lines, dispensers,
electric conduits, vent lines, etc.) and that no drilling or excavation should be performed within
this zone without the specific pre-approval by the client manager and/or senior technical
manager. See example site sketch attached.
Confirm the size and types of USTs present (fiberglass, steel, etc.) in order to determine the
minimal step-out drilling or excavation distance.
Consider the elimination of any high risk task that may be included as part of the scope of
work (i.e. not installing a boring in a high-traffic area or keeping a boring outside of the UST
equipment exclusion zone).
Make arrangements in the budget and scope of work to pre-clear each boring using hand
tools or an air-vacuum excavator/air knife.
When performing subsurface assessment work at retail facilities, field staff will be required to do the
following list of activities:
Conduct a site walkover to visually identify known or potential structures or equipment (e.g.
concrete pads, re-paved portions of the parking lot, etc.). Using a copy of the DigSafe form
for reference, the location of each utility will be identified.
If not already completed during the Dig Safe process, once utility locations have been
identified, each proposed boring location will be marked-out with white paint and if possible
inspected and approved by the retail facility manager. NOTE: No drilling activities will be
completed in the UST equipment exclusion zone without pre-approval.
Field staff will make sure they are knowledgeable of all emergency response procedures for
the facility including the location of the emergency shut-offs for the UST system and
evacuation procedures prior to the start of any pre-clearing activities.
AECOM Environment
May 20121

5-22
Each boring will be pre-cleared using hand tools or an air-vacuum excavator/air knife. The
diameter of the pre-cleared boring will be, at a minimum, 3-inches greater than the drill bit on
the lead auger to be used. The boring will be cleared to a depth of 5 feet or deeper per
regional guidelines below surface grade. If approval has been granted to drill within the UST
equipment exclusion zone, the diameter of the pre-cleared boring will be 6-inches greater
than the drill bit on the lead auger to be used. NOTE: That the pre-cleared boring will need to
be re-cleared if augers are switched out during the drilling event to a larger diameter auger.
During the pre-digging (digging) process for soil borings and monitoring wells, no further
digging or excavation will occur if any of the following conditions exist:
Peastone
Fill sand
Any other well-sorted, non-local material
Debris
Plastic, PVC, fiberglass or other UST or pipe-related material
Resistance or obstructions
The pre-drilled boring will be visually inspected by the field staff and the driller with a
flashlight. The boring needs to be inspected to insure that a utility line is not present on the
immediate perimeter or base of the cleared boring.
Once the pre-drilled boring has been cleared and the augers have been placed into the hole:
Drilling should advance at a relatively slow rate to a depth of 10 feet below surface grade. In
sand, silt or clay soils the cutting key should be removed.
A quick inspection is performed of the initial soil returns to verify that no plastic, PVC,
fiberglass or other piping material is present.
NOTE: In the event there is any evidence of contact with an underground utility or structure, drilling
will immediately cease and the situation will be evaluated prior to the removal of equipment or augers.
5.24.2 Overhead Utilities
All overhead lines will be considered “energized” unless properly de-energized, grounded and tested
by the utility company before working within the clearance distance as defined below. The AECOM
SSO must observe de-energizing process and reconfirm that the lines are de-energized on a daily
basis.
Any vehicle or mechanical equipment that is capable of having parts of its structure elevated near
energized overhead lines shall be operated so that a minimum clearance of 10 feet is maintained at all
times. This 10 foot distance shall be increased a minimum of 0.4 inches for each 1 kV over 50 kV. If
the voltage of the overhead line is unknown, maintain a clearance distance of 35 feet from ground
projection of the nearest power line to the vehicle. Any work within the clearance distance must be
approved by the Regional Health and Safety Manager and the utility company.
Precautions must be taken when handling lengths of pipe or tubing that can approach overhead
power and utility lines. When working with pipe or tubing, maintain a distance equal to the length of
pipe plus the clearance distance defined above.
AECOM Environment
May 20121

5-23
Personnel should also be aware of the limited clearance associated with the canopy that typically
covers the dispensing island.
5.25 Weather
5.25.1 Inclement Weather
The Site Safety Officer will check the weather forecast for the project area each morning prior to
mobilization. Predicted weather conditions will be included in the Job Safety Analysis. Weather
changes should initiate a review and update of the JSA as necessary.
Severe weather can occur with little warning. The employee must be aware of the potentials for
lightning, flash flooding and high wind events.
Be Prepared, Know what is Coming your Way
Listen to the radio for severe weather alerts.
Check the Storm Prediction Center's web page for alerts and warnings.
http://www.spc.noaa.gov/products/wwa/
Pay attention to the weather in your area, up wind of your location, and in the watershed up-
stream from your location.
When in the field, be aware of the route you must take to get to shelter.
When working in low areas be aware of the potential for flash flooding and the route to higher
ground.
5.25.2 Heat Stress
Types of Heat Stress
Heat related problems include heat rash, fainting, heat cramps, heat exhaustion and heat stroke.
Heat rash can occur when sweat isn't allowed to evaporate; leaving the skin wet most of the time and
making it subject to irritation. Fainting may occur when blood pools to lower parts of the body and as
a result, does not return to the heart to be pumped to the brain. Heat related fainting often occurs
during activities that require standing erect and immobile in the heat for long periods of time. Heat
cramps are painful spasms of the muscles due to excessive salt loss associated with profuse
sweating.
Heat exhaustion is a result of the loss of large amounts of fluid and excessive loss of salt from
profuse sweating. The skin will be clammy and moist and the affected individual may exhibit
giddiness, nausea and headache.
Heat stroke occurs when the body's temperature regulatory system has failed. The skin is hot, dry,
red and spotted. The affected person may be mentally confused and delirious. Convul¬sions could
occur. EARLY RECOGNITION AND TREATMENT OF HEAT STROKE ARE THE ONLY MEANS OF
PREVENTING BRAIN DAMAGE OR DEATH. A person exhibiting signs of heat stroke should be
removed from the work area to a shaded area. The person should be soaked with water to promote
evaporation. Fan the person's body to increase cooling.
AECOM Environment
May 20121

5-24
Increased body temperature and physical discomfort also promote irritability and a decreased
attention to the performance of hazardous tasks.
Early Symptoms of Heat-Related Health Problems:
decline in task performance excessive fatigue
in-coordination reduced vigilance
decline in alertness muscle cramps
unsteady walk dizziness
Susceptibility to Heat Stress Increases due to:
lack of physical fitness obesity
lack of acclimatization drug or alcohol use
increased age sunburn
dehydration infection
People unaccustomed to heat are particularly susceptible to heat fatigue. First timers in PPE need to
gradually adjust to the heat.
The Effect of Personal Protective Equipment
Sweating normally cools the body as moisture is removed from the skin by evaporation. However, the
wearing of certain personal protective equipment (PPE), particularly chemical protective coveralls
(e.g., Tyvek), reduces the body's ability to evaporate sweat and thereby regulate heat buildup. The
body's efforts to maintain an acceptable temperature can therefore become significantly impaired by
the wearing of PPE.
Measures to Avoid Heat Stress:
The following guidelines should be adhered to when working in hot environments:
Establish work-rest cycles (short and frequent are more beneficial than long and seldom).
Identify a shaded, cool rest area.
Rotate personnel, alternative job functions.
Water intake should exceed sweat produced. Most workers exposed to hot conditions drink
less fluids than needed because of an insufficient thirst. DO NOT DEPEND ON THIRST TO
SIGNAL WHEN AND HOW MUCH TO DRINK. Consume enough liquid to force urination
every two hours. In humid climates ice water or ice should be consumed to help maintain
normal body temperature since evaporation does not provide an efficient mechanism for heat
removal.
Eat light meals before and during work shifts. Avoid highly salted foods.
Drink sports drinks such as Gatorade® diluted 1:1 with water.
AECOM Environment
May 20121

5-25
Save most strenuous tasks for non-peak heat hours such as the early morning or at night.
Avoid alcohol during prolonged periods of heat. Alcohol will cause additional dehydration.
Avoid double shifts and/or overtime.
The implementation and enforcement of the above mentioned measures will be the joint responsibility
of the Project Manager and health and the Site Safety Officer. Potable water and fruit juices should
be made available each day for the field team.
Heat Stress Monitoring Techniques
Site personnel should regularly monitor their heart rate as an indicator of heat strain by the following
method:
Radial pulse rates should be checked by using fore-and middle fingers and applying light pressure top
the pulse in the wrist for one minute at the beginning of each rest cycle. If the pulse rate exceeds 110
beats-per- minute (bpm), the next work cycle will be shortened by one-third and the rest period will be
kept the same. If, after the next rest period, the pulse rate still exceeds 110 bpm, the work cycle will be
shortened again by one-third.
5.25.3 Cold Stress
Type of Cold Stress
Cold injury is classified as either localized, as in frostbite, frostnip or chilblain; or generalized, as in
hypothermia. The main factors contributing to cold injury are exposure to humidity and high winds,
contact with wetness and inadequate clothing.
The likelihood of developing frostbite occurs when the face or extremities are exposed to a cold wind
in addition to cold temperatures. The freezing point of the skin is about 30o F. When fluids around the
cells of the body tissue freeze, skin turns white. This freezing is due to exposure to extremely low
temperatures. As wind velocity increases, heat loss is greater and frostbite will occur more rapidly.
Symptoms of Cold Stress
The first symptom of frostbite is usually an uncomfortable sensation of coldness, followed by
numbness. There might be a tingling, stinging or aching feeling in the affected area. The most
vulnerable parts of the body are the nose, cheeks, ears, fingers and toes.
Symptoms of hypothermia, a condition of abnormally low body temperature, include uncontrollable
shivering and sensations of cold. The heartbeat slows and can become irregular, the pulse weakens
and the blood pressure changes. Pain in the extremities and severe shivering can be the first warning
of dangerous exposure to cold.
Maximum severe shivering develops when the body temperature has fallen to 95o F. Productive
physical and mental work is limited when severe shivering occurs. Shivering is a serious sign of
danger. Immediately remove any person who is shivering from the cold.
Methods to Prevent Cold Stress
AECOM Environment
May 20121

5-26
When the ambient temperature, or a wind chill equivalent, falls to below 40o F (American Conference
of Governmental Industrial Hygienists recommendation), site personnel who must remain outdoors
should wear insulated coveralls, insulated boot liners, hard hat helmet liners and insulated hand
protection. Wool mittens are more efficient insulators than gloves. Keeping the head covered is very
important, since 40% of body heat can be lost when the head is exposed. If it is not necessary to wear
a hard hat, a wool knit cap provides the best head protection. A facemask may also be worn.
Persons should dress in several layers rather than one single heavy outer garment. The outer piece of
clothing should ideally be wind and waterproof. Clothing made of thin cotton fabric or synthetic fabrics
such as polypropylene is ideal since it helps to evaporate sweat. Polypropylene is best at wicking
away moisture while still retaining its insulating properties. Loosely fitting clothing also aids in sweat
evaporation. Denim is not a good protective fabric. It is loosely woven which allows moisture to
penetrate. Socks with a high wool content are best. If two pairs of socks are worn, the inner sock
should be smaller and made of cotton, polypropylene or similar types of synthetic material that wick
away moisture. If clothing becomes wet, it should be taken off immediately and a dry set of clothing
put on.
If wind conditions become severe, it might become necessary to shield the work area temporarily. The
SSO and the PM will determine if this type of action is necessary. Heated break trailers or a
designated area that is heated should be available if work is performed continuously in the cold at
temperatures, or equivalent wind chill temperatures, of 20o F.
Dehydration occurs in the cold environment and can increase the susceptibility of the worker to cold
injury due to significant change in blood flow to the extremities. Drink plenty of fluids, but limit the
intake of caffeine
5.25.4 Work/Rest Cycles for Cold Weather
If wind chill temperatures fall below minus 25º F, breaks from the cold will occur at a rate of one every
hour. If wind chill temperatures fall below minus 45º F, all work will cease and persons will be
required to go indoors. Also see Section 1.1.1 regarding shift duration. However, these guidelines
can be modified at any time based on actual site conditions and professional judgment rendered by
either the Field Manger and/or SSO. For example, the Field Manger and/or SSO will evaluate field
crew fitness; the condition of their cold-weather gear, including boots; and will observe employees
alertness, including fatigue and rate of cold tolerance/acclimation.
If weather conditions warrant, portable tents might become necessary to shield the work area from
wind, rain, snow, etc. The SSO and the Field Manager will determine if this type of action is
necessary. However, under no conditions will the tents be heated and as a precautionary measure, a
Photoionization Detector (PID) with a 10.6 eV lamp will be used to monitor the breathing zone of
personnel inside the tent. See Section 6 for action levels based on PID readings. A JSA should be
prepared and discussed with all workers detailing the precautions for working in these cold weather
conditions.
5.26 Well Development and Groundwater Monitoring
During purging and development of borings into monitoring wells, the PPE indicated in Section 7
below will be worn to avoid chemical contact / exposure, as well as physical trauma. Bailing wells
AECOM Environment

requires proper gloves, eye protection, and possibly protective coveralls to prevent splashing. Back
and lifting precautions outlined in this document shall be used to avoid ergonomic injuries.
5.27 Confined Spaces
No confined space entries are planned or allowed on this project.
When working in industrial settings, it is common to need to enter a confined space to make
observations, collect samples, or perform other duties. AECOM employees or sub contractors must
not enter any confined space containing a hazard...
A confined space is defined as any space that meets the following criteria:
Is not designed for human occupancy (excludes vehicles, elevator cabins etc,)(includes
elevator shafts and wells, tanks, vaults, etc.)
Is large enough to physically enter with the whole body, and
Has a restricted exit path (you must climb over pipes, through manways, etc.)
If the confined space contains any hazard, entry may only be made if permitted in writing by the space
owner or the Regional Health and Safety Manger, the entry is monitored by an observer, and with the
prior written approval of the AECOM Regional Health and Safety Manager.
Typical hazards include but are not limited to:
Flammable materials
Toxic materials
Corrosive materials
Exposed electrical circuits
Falls greater than six feet
Moving machinery
Oxygen deficient atmosphere
If there is any doubt about whether a space meets the above criteria, call the AECOM Health and
Safety Staff.

6.0 Air Monitoring
6.1 Monitors
NOTE: All subcontractors are responsible for providing, calibrating and maintaining all equipment,
meters and monitoring devices that will be required for them to successfully completing their work.
6.1.1 Photoionization Detector
As a precautionary measure, a Photoionization Detector (PID) with a 10.6 eV lamp will be used to
monitor the breathing zone of personnel during the proposed activities. If the PID indicates sustained
(5 minute) breathing zone vapor concentrations in excess of 5 ppm as isobutylene, respiratory
protection, as described in Section 7.2 of this document, will be donned.
A MultiRAE Plus, is a PID equipped with, Oxygen, LEL and two toxic gas sensors (CO, Hydrogen
Sulfide), which would replace the requirement for an oxygen, explosive gas and carbon monoxide
meters.
6.1.2 Oxygen Meter
An oxygen meter will be used to monitor all atmospheres requiring an explosive gas meter. The
oxygen level will be determined prior to the explosive gas level to assure that there is sufficient oxygen
to support both human life and to allow the explosive gas meter to operate properly.
6.1.3 Explosive Gas Meter
An explosive gas meter will be used to confirm that work area atmospheres contain less than 10%
LEL before any cutting, welding, or other hot work is initiated and to monitor those areas during the
activities.
An explosive gas meter will be used to determine and monitor the air quality in any confined space
entered.
If the PID reading indicates a sustained (1 minute) concentration at any location in excess of 500 ppm
as isobutylene or the instrument reads an off scale high concentration, a combustible gas meter will
be obtained and used to verify that no concentrations exceed ten percent (10%) of the Lower
Explosive Limit (LEL). If concentrations exceed 10% of LEL, all spark and heat producing equipment
will be shut down until the concentration can be reduced below 10% of LEL.
6.1.4 Colorimetric Detector Tubes/Draeger Chip System
If a properly calibrated PID reads 5 ppm as isobutylene sustained for 5 minutes colorimetric detector
tubes, e.g. Draeger or Sensydine, or a Draeger Chip system equipped with the appropriate constituent
monitoring chip, shall be used to confirm the presence and concentration of site-specific chemicals of
concern, e.g. benenze. If a site-specific chemical of concern is detected at concentration of half its’
PEL then respiratory protection shall be used as described in Section 7.2 of this document.
AECOM Environment
May 20121

6-2
6.1.5 Carbon Monoxide Meter
If hydrocarbon fuels such as gasoline, diesel, natural gas, or propane are used inside a building, a CO
meter must be used to monitor the build up of exhaust gas in the building. The unit will be set to alarm
at 25 ppm. If the alarm sounds, work will cease and all employees will leave the building. If carbon
monoxide concentrations cannot be reduced, mechanical ventilation may be required. Even if the
building is well-ventilated and the exhaust gas is ducted to the outside, a CO meter is still required.
6.1.6 Dust/Particulate Meter
A particulate meter will be used to monitor dust levels within the work zone. If particulate levels
exceed 1.0 mg/m3 in air, respiratory protection, as described in Section 7.2 of this document, will be
donned. Additionally, actions will be taken to suppress particulates in the work area.

8 Snake protection (e.g., boots and snake chaps) should be worn when walking through vegetated areas.
9 When working in areas with high potential for excessive contact with hazardous chemicals, precautions will be taken to
reduce the potential for direct dermal contact that may incorporate the use of polycoated Tyvek, double gloves, and
additional protective measures based upon the permeability of the PPE chosen and the potential for chemicals of concern
to degrade the selected PPE.
7.2 Respiratory Protection
As a precautionary measure, a Photoionization Detector (PID) with a 10.6 ev lamp will be used to
monitor the breathing zone of personnel during the proposed activities. If the PID indicates sustained

irritation is noticed.
All employees who are expected to don respiratory protection must have successfully passed a
qualitative or quantitative fit-test within the past year for the brand, model and size respirator they plan
to don.
If worn, respirators will be cleaned after each use with respirator wipe pads and will be stored in
plastic bags after cleaning. Respirators will be thoroughly cleaned using disinfectant material within
one week following any respirator use. Refer to the cleaning instructions provided with the respirator
or specified by Appendix B-2 to the OSHA regulations at 29 CFR 1910.134.

8.0 Site Control
To prevent both exposure of unprotected personnel and migration of contamination due to tracking by
personnel or equipment, hazardous work areas will be clearly identified and decontamination
procedures will be required for personnel and equipment leaving those areas.
8.1 Designation of Zones
AECOM designates work areas or zones as suggested in the "Occupational Safety and Health
Guidance Manual for Hazardous Waste Site Activities," NIOSH/OSHA/USCG/EPA, November 1985.
They recommend that the areas surrounding each of the work areas to be divided into three zones:
Exclusion or "Hot" Zone
Contamination Reduction Zone
Support Zone
8.1.1 Exclusion Zone
An exclusion zone will be established around the work area. The perimeter of the exclusion zone will
be marked with caution tape, traffic cones or other identifier so that employees, visitors, and client or
host employer personnel are aware of the work being conducted.
All AECOM and contractor personnel entering these work areas must wear the prescribed level of
protective equipment.
8.1.2 Contamination Reduction Zone
A decontamination zone will be established adjacent to each work area. Personnel will remove
contaminated gloves and other disposable items in this area and place them in a plastic bag until they
can be properly disposed of.
8.1.3 Support Zone
At this site the support zone will include the area outside of the exclusion zone.
8.1.4 Site Access Control
The public will be restricted from the project site and monitoring well locations (during monitoring) by
fences, barricade tape, traffic cones, and/or signs.
8.1.5 Parking and Staging Areas
Parking will be restricted to areas that have been cleared of tall grass and combustible material.
Vehicles parked on the public streets will be marked with cones both in front of and behind the vehicle.
AECOM Environment
May 20121

8-2
8.1.6 Pedestrian Walkways
Pathways within the work areas will be kept clear of obstructions. Public pathways will be clearly
marked to provide access to the business onsite and protect the public from the hazards of the
project.
8.2 General Site Safety Practices
The following measures are designed to augment the specific health and safety guidelines provided in
this plan.
The "buddy system" will be used by field personnel. Subcontractors working on-site with
AECOM employees can help fulfill the role of a buddy while site activities are occurring. The
store clerk can also fulfill the role of a buddy while site activities are occurring. If an
employee will be alone in a work area, they will develop a procedure to contact their
Supervisor or PM on a regular schedule to confirm that the employee is safe
Eating, drinking, chewing gum or tobacco, smoking or any practice that increases the
probability of hand-to-mouth transfer and ingestion of materials is prohibited in the immediate
work area and the decontamination zone. Water and Ice may be consumed in all areas to
prevent heat stress but precautions must be taken to prevent contamination of the water and
ice.
Smoking is prohibited in all work areas.
Hands and face must be thoroughly washed upon leaving the work area and before eating,
drinking or any other activities.
Beards or other facial hair that interfere with respirator fit are prohibited.
The use of alcohol or illicit drugs is prohibited during the conduct of field operations.
All equipment must be decontaminated or properly discarded before leaving the site in
accordance with the project work plan.
Parking and pedestrian areas will be established and communicated to all workers.

AECOM Environment
May 20121

9-1
9.0 Decontamination
9.1 Personal Decontamination
Proper decontamination is required of all personnel before leaving the site. Decontamination will occur
within the contamination reduction zone.
Regardless of the type of decontamination system required, a container of potable water and liquid
soap should be made available so employees can wash their hands and face before leaving the site
for lunch or for the day.
9.2 PPE Decontamination
Disposable PPE, such as Tyvek coveralls, gloves, etc. will be removed in the decon zone and placed
in garbage bags. Final disposal of contaminated PPE will be in accordance with the work plan.
If worn, respirators assigned to an individual will be cleaned after each use with respirator wipe pads
and will be stored upright in plastic bags. Respirators will be thoroughly cleaned using disinfectant
material within one week following any respirator use. Respirators that have the potential to be shared
by employees within the workplace will be completely dismantled and thoroughly cleaned after each
use. Refer to the cleaning instructions provided with the respirator or specified by Appendix B-2 to the
OSHA regulations at 29 CFR 1910.134.
9.3 Equipment Decontamination
Equipment will be decontaminated prior to being moved to other locations. Decontamination
procedures will be specified by the Project Manager.

10.0 Medical Monitoring and Training Requirements
Each worker subject to this HASP shall have copies of documentation that the requirements for
training, medical surveillance, and respirator use are current. Copies of these documents shall be
made available to AECOM or AECOM’s client upon request.
10.1 Medical Monitoring
All personnel performing activities covered by this HASP must be active participants in a medical
monitoring program that complies with 29 CFR 1910.120(f). Each individual must have completed an
annual surveillance examination and/or an initial baseline examination within the last year prior to
performing any work on the site covered by this HASP.
10.2 Health and Safety Training
10.2.1 HAZWOPER
All personnel performing activities covered by this HASP must have completed the appropriate
training requirements specified in 29 CFR 1910.120 (e). Each individual must have completed an
annual 8-hour refresher training course and/or initial 40-hour training course within the last year prior
to performing any work on the sites covered by this HASP.
10.2.2 Pre-Entry Briefing/Tailgate Meetings
Prior to the commencement of daily project activities, a pre-entry briefing or tailgate meeting will be
conducted by the SSO to review the specific requirements of this HASP, review and revise the JSA,
discuss Incidents, Near Misses and lessons learned from the previous day’s activities, and discuss
site conditions that have changed since the previous day or trip to the site. Attendance at the daily
tailgate meeting is mandatory for all personnel covered by this HASP at the site and must be
documented on the attendance form provided in Attachment D. HASP sign-off sheets should also be
collected at the time of the tailgate meetings. All documentation should be maintained in the project
file.
The pre-entry briefing must be completed for each new employee before they begin work at the site.
Short safety refresher meetings will be conducted, as needed, throughout the duration of the project.

AECOM Environment
May 20121

11-1
11.0 Emergency Response
OSHA defines emergency response as any "response effort by employees from outside the
immediate release area or by other designated responders (i.e., mutual-aid groups, local fire
departments, etc.) to an occurrence which results, or is likely to result in an uncontrolled release of a
hazardous substance." According to AECOM policy, AECOM personnel shall not participate in any
emergency response where there are potential safety or health hazards (i.e., fire, explosion, or
chemical exposure). AECOM response actions will be limited to evacuation and medical/first aid as
described within this section below. As such this section is written to comply with the requirements of
29 CFR 1910.38 (a).
The basic elements of an emergency evacuation plan include:
employee training,
alarm systems,
escape routes,
escape procedures,
critical operations or equipment,
rescue and medical duty assignments,
designation of responsible parties,
emergency reporting procedures and
methods to account for all employees after evacuation.
11.1 Spill Response
Employees are only authorized to respond to incidental spills and releases of hazardous substances.
The following criteria must be met for a spill to be considered incidental with the employee having the
ability to respond to the spill:
Quantity of spilled material is minimal enough where additional, third party assistance is not
needed to manage the spill
Material is not immediately threatening to impact an open water way
The conditions of the spill do not present a hazardous condition that is immediately
dangerous to life and health (IDLH)
The employee responding has:
received training on proper spill response techniques relative to the spilled material
full knowledge of what has been spilled and the proper clean up techniques to be used
the means to protect themselves against exposure to harmful conditions caused by the spill
including the necessary PPE
AECOM Environment
May 20121

11-2
the means to containerize and dispose of the spilled material properly
Employees may be equipped with the following materials, assembled into a spill response kit, to
manage incidental workplace spills:
Absorbent pads or media, i.e. speedy-dry, kitty litter
Broom and dust pan to clean up spent granular spill control media or impacted earth
Shovel to clean up impacted earth or create a dam or dike to prevent the spill area from
increasing
Disposal drums and over-pack drums
Appropriate waste identification labels
Appropriate PPE
If a spill is not considered incidental, then additional assistance will be sought to aid in clean-up. The
responding employee shall contact the Project Manager and provide initial notification of the release.
The Project Manager will then notify the client representative and determine a suitable course of
action. . Consideration will need to be given to whether or not the spill is deemed to be a reportable
quantity (RQ) by the EPA, if the National Spill Response Center needs to be contacted due to surface
water impact, and if local, state or federal agencies need to be contacted to provide information
related to public health threats and environmental impact.
All spills must be reported to the AECOM PM and RSM, with the PM providing notification to the client
representative, no matter how small the spill is. After initial response actions have been completed an
incident investigation will be performed to determine the root causes of the incident and corrective
actions, and lessons learned shall be shared to prevent future reoccurrence. Once the response is
complete, the responding employee will also conduct an inventory of supplies used during the
response effort and re-stock any used response equipment that could not be decontaminated and
reused.
11.2 Employee Training
Employees must be instructed in the site-specific aspects of emergency evacuation. On-site refresher
or update training is required anytime escape routes or procedures are modified or personnel
assignments are changed.
11.3 Alarm System/Emergency Signals
An emergency communication system must be in effect at all sites. The simplest and most and
effective emergency communication system in many situations will be direct verbal communications.
Each site must be assessed at the time of initial site activity and periodically as the work progresses.
Verbal communications must be supplemented anytime voices cannot be clearly perceived above
ambient noise levels (i.e., noise from heavy equipment; drilling rigs, backhoes, etc.) and anytime a
clear line-of-sight cannot be easily maintained amongst all AECOM personnel because of distance,
terrain or other obstructions.
Verbal communications will be adequate to warn employees of hazards associated with the
immediate work area. The property is occupied but AECOM may not have access to facility phones.
AECOM Environment
May 20121

11-3
Therefore, AECOM will bring a portable phone to the site to ensure that communications with local
emergency responders is maintained, when necessary.
11.4 Escape Routes and Procedures
The escape route from the site and an emergency muster point will be determined and provided to all
workers during the project mobilization.
Prior to mobilizing to a new project area, the Site Safety Officer or his designee will confirm that the
escape routes are clear and lead to a safe area.
11.5 Employee Accounting Method
The SSO is responsible for identifying all AECOM personnel on-site at all times. AECOM and its
subcontract employees will notify the SSO when they enter and leave the site. The SSO will account
for all AECOM and its subcontract employees following an evacuation.
11.6 Injuries and Illnesses
The phone numbers of the police and fire departments, ambulance service, local hospital, and
AECOM representatives are provided in the emergency reference sheet on page 1. This sheet will be
posted in the site vehicle.
11.6.1 First Aid
Minor injuries will be treated on site using materials from the first aid kit or other local sources. All cuts
and abrasions will be cleaned with potable water and a clean dressing applied. The injured employee
will be evaluated at the end of the work day and the following day when the employee arrives at the
project site to determine whether the wound has started the healing process. The wound will be
protected from contamination during the project activities.
11.6.2 Professional Treatment
In the event an injury or illness requires more than first aid treatment, the SSO will accompany the
injured person to the medical facility and will remain with the person until release or admittance is
determined. The escort will relay all appropriate medical information to the on-site project manager
and the RSM.
If the injured employee can be moved from the accident area, he or she will be brought to the CRZ
where their PPE will be removed. If the person is suffering from a back or neck injury the person will
not be moved and the requirements for decontamination do not apply. The SSO must familiarize the
responding emergency personnel about the nature of the site and the injury. If the responder feels that
the PPE can be cut away from the injured person's body, this will be done on-site. If this not feasible,
decontamination will be performed after the injured person has been stabilized.
11.7 Designation of responsible parties
The SSO is responsible for initiating emergency response. In the event the SSO cannot fulfill this duty,
the alternate SSO will take charge.
AECOM Environment
May 20121

11-4
11.8 Emergency Response Drills
For projects with durations of greater than four days on site, the SSO will initiate an evacuation drill
during the first five days and shall repeat the drills at least quarterly. Deficiencies noted during the
drills will be documented as a Near Loss, a Root Cause Analysis conducted and corrective actions
initiated.
A table-top run through of the evacuations procedures from the manufacturing site will be conducted
the first day on the site and reviewed with all workers arriving on site after that date.
Emergency Response drills and subsequent personnel briefings on evacuation procedures will be
documented in the safety briefing agenda or briefing notes.
11.9 Incident Reporting and Investigation
Any incident (other than minor first aid treatment) resulting in injury, illness or property damage
requires an Incident investigation and report. The investigation should be conducted as soon as
emergency conditions are under control. The purpose of the investigation is not to attribute blame but
to determine the pertinent facts so that repeat or similar occurrences can be avoided. An AECOM
Incident investigation form is presented in Attachment E of this HASP. The injured AECOM
employee's supervisor, the AECOM Project Manager, and the RSM should be notified immediately of
the injury.
If a subcontractor employee is injured, they are required to notify the AECOM SSO. Once the incident
is under control, the subcontractor will submit a copy of their company's Incident investigation report to
the AECOM SSO.

Auger Operations - What to look for:
A system of responsibility between the operator and the tool handler when
connecting and disconnecting auger sections and inserting and removing auger
fork.
During connecting and disconnecting auger sections and inserting auger for the
tool, handler should position himself away from the auger column while it is
rotating.
When securing the auger to the power coupling, pin should be inserted and tapped
into place using a hammer or other similar device.
Tool hoist should be used to lower second section of auger into place.
Both operators should be clear of auger as it is being lifted into place.
Long-handled shovel should be used to move dirt away from auger.

INHALATION: This product is non-toxic. Air, the main component of this product, is necessary for life.

OTHER POTENTIAL HEALTH EFFECTS: Contact with rapidly expanding gases (which are released
under high pressure) may cause frostbite. Symptoms of frostbite include change in skin color to white
or grayish-yellow. The pain after contact with liquid can quickly subside.

HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms. Over-exposure
to this product may cause the following health effects:

ACUTE: The most significant hazards associated with compressed air is the pressure hazard.
Contact with rapidly expanding gases (which are released under high pressure) may cause frostbite.
Symptoms of frostbite include change in skin color to white or grayish-yellow. The pain after contact
with liquid
can quickly subside.

CHRONIC: There are currently no known adverse health effects associated with chronic exposure to
this gas.

TARGET ORGANS: ACUTE: Respiratory system under ambient low pressure conditions. Central
nervous system under ambient high pressure conditions. CHRONIC: None expected.

PART II What should I do if a hazardous situation occurs?
4. FIRST-AID MEASURES
RESCUERS SHOULD NOT ATTEMPT TO RETRIEVE VICTIMS OF EXPOSURE TO THIS
PRODUCT WITHOUT ADEQUATE PERSONAL PROTECTIVE EQUIPMENT. At a minimum, Self-
Contained Breathing Apparatus equipment should be worn.
Victim(s) must be taken for medical attention. Rescuers should be taken for medical attention, if
necessary. Take copy of label and MSDS to physician or other health professional with victim(s).
Remove victim(s) to fresh air, as quickly as possible. In case of eye contact which leads to irritation,
immediately flush eyes with copious amounts of water for at least 15 minutes. If not breathing, give
artificial respiration. If breathing is difficult, give oxygen. Only trained personnel should administer
supplemental oxygen.
In case of frostbite, place the frostbitten part in warm water. DO NOT USE HOT WATER. If warm
water is not available, or is impractical to use, wrap the affected parts gently in blankets. Alternatively,
if the fingers or hands are frostbitten, place the affected area in the armpit. Encourage victim to gently
exercise the affected part while being warmed. Seek immediate medical attention.

5. FIRE-FIGHTING MEASURES (Continued)
FIRE EXTINGUISHING MATERIALS: Non-flammable gas. Use extinguishing media appropriate for
surrounding fire.
UNUSUAL FIRE AND EXPLOSION HAZARDS: When involved in a fire, this material may
decompose and produce toxic gases including carbon monoxide and carbon dioxide. Additionally,
when involved in fire, the cylinders may rupture.
Explosion Sensitivity to Mechanical Impact: Not Sensitive.
Explosion Sensitivity to Static Discharge: Not Sensitive.
SPECIAL FIRE-FIGHTING PROCEDURES: Structural firefighters must wear Self-Contained
Breathing Apparatus and full protective equipment. Move fire-exposed cylinders from area, if it can
be done without risk to fire-fighters. Withdraw immediately in case of rising sounds from venting
pressure relief devices or any discoloration of tanks or cylinders due to a fire.

6. ACCIDENTAL RELEASE MEASURES
SPILL AND LEAK RESPONSE: Uncontrolled releases should be responded to by trained personnel
using pre-planned procedures. Proper protective equipment should be used. In case of a release,
clear the affected area, protect people, and respond with trained personnel. Minimum Personal
Protective Equipment should be Level D: safety glasses, and mechanically-resistant gloves.
Level B, which includes the use of Self- Contained Breathing Apparatus, should be worn
when oxygen levels are below 19.5% or are unknown. Locate and seal the source of the leaking
gas. If this does not stop the release (or if it is not possible to reach the valve), allow the gas to
release in place or remove it to a safe area and allow the gas to be released there.

PART III How can I prevent hazardous situations from occurring?
7. HANDLING and STORAGE
WORK PRACTICES AND HYGIENE PRACTICES: Do not eat or drink while handling chemicals.
STORAGE AND HANDLING PRACTICES: Cylinders should be stored in dry, well-ventilated areas
away from sources of heat. Compressed gases can present significant safety hazards. Store
containers away from heavily trafficked areas and emergency exits.
SPECIAL PRECAUTIONS FOR HANDLING GAS CYLINDERS: Protect cylinders against physical
damage. Store in cool, dry, well-ventilated, fireproof area, away from flammable or combustible
materials and corrosive atmospheres. Store away from heat and ignition sources and out of direct
sunlight. Do not store near elevators, corridors or loading docks. Do not allow area where cylinders
AECOM Environment

\\usral1vfp001\JOBS\Projects\S\7-Eleven\Kill Devil Hills\20-day report\Appendices\App A - 19847 HASP (on CD).doc November 2011
are stored to exceed 52 C (125 F). Isolate from incompatible materials including flammable materials
(see Section 10, Stability and Reactivity), which can burn violently. Use only storage containers and
equipment (pipes, valves, fittings to relieve pressure, etc.) designed for the storage of Air. Do not
store containers where they can come into contact with moisture. Cylinders should be stored upright
and be firmly secured to prevent falling or being knocked over. Cylinders can be stored in the open,
but in such cases, should be protected against extremes of weather and from the dampness of the
ground to prevent rusting. Never tamper with pressure relief devices in valves and cylinders. The
following rules are applicable to situations in which cylinders are being used:
Before Use: Move cylinders with a suitable hand-truck. Do not drag, slide or roll cylinders. Do not
drop
cylinders or permit them to strike each other. Secure cylinders firmly. Leave the valve protection cap
in-place until cylinder is ready for use.
During Use: Use designated CGA fittings and other support equipment. Do not use adapters. Do not
heat cylinder by any means to increase the discharge rate of the product from the cylinder. Use
check valve or trap in discharge line to prevent hazardous backflow into the cylinder. Do not use oils
or grease on gas-handling fittings or equipment.
After Use: Close main cylinder valve. Replace valve protection cap. Mark empty cylinders “EMPTY”.
NOTE: Use only DOT or ASME code containers. Earth-ground and bond all lines and equipment
associated with this product. Close valve after each use and when empty. Cylinders must not be
recharged except by or with the consent of owner. For additional information refer to the Compressed
Gas Association Pamphlet P-1, Safe Handling of Compressed Gases in Containers. Additionally,
refer to CGA Bulletin SB-2 “Oxygen Deficient Atmospheres”.

7. HANDLING and STORAGE (Continued)
PROTECTIVE PRACTICES DURING MAINTENANCE OF CONTAMINATED EQUIPMENT: Follow
practices indicated in Section 6 (Accidental Release Measures). Make certain application equipment
is locked and tagged out safely. Purge gas handling equipment with inert gas (i.e. nitrogen) before
attempting repairs. Always use product in areas where adequate ventilation is provided.

8. EXPOSURE CONTROLS - PERSONAL PROTECTION

DEFINITIONS OF TERMS
A large number of abbreviations and acronyms appear on a MSDS. Some of these which are
commonly used include the following:
CAS #: This is the Chemical Abstract Service Number which uniquely identifies each constituent.
EXPOSURE LIMITS IN AIR:
ACGIH - American Conference of Governmental Industrial Hygienists, a professional association
which establishes exposure limits. TLV - Threshold Limit Value - an airborne concentration of a
substance which represents conditions under which it is generally believed that nearly all workers
may be repeatedly exposed without adverse effect. The duration must be considered, including the 8-
hour Time Weighted Average (TWA), the 15-minute Short Term Exposure Limit, and the
instantaneous Ceiling Level (C). Skin absorption effects must also be considered.

OSHA - U.S. Occupational Safety and Health Administration. PEL - Permissible Exposure Limit -
This exposure value means exactly the same as a TLV, except that it is enforceable by OSHA. The
OSHA
Permissible Exposure Limits are based in the 1989 PELs and the June, 1993 Air Contaminants Rule
(Federal Register: 58: 35338-35351 and 58: 40191). Both the current PELs and the vacated PELs
are
indicated. The phrase, “Vacated 1989 PEL,” is placed next to the PEL which was vacated by Court
Order.

IDLH - Immediately Dangerous to Life and Health - This level represents a concentration from which
one can escape within 30- minutes without suffering escape-preventing or permanent injury. The
DFG - MAK is the Republic of Germany’s Maximum Exposure Level, similar to the U.S. PEL. NIOSH
is the National Institute of Occupational Safety and Health, which is the research arm of the U.S.
Occupational Safety and Health Administration (OSHA). NIOSH issues exposure guidelines called
Recommended Exposure Levels (RELs). When no exposure guidelines are established, an entry of
NE is made for reference.

HAZARD RATINGS:
HAZARDOUS MATERIALS IDENTIFICATION SYSTEM: Health Hazard: 0 (minimal acute or
chronic exposure hazard); 1 (slight acute or chronic exposure hazard); 2 (moderate acute or
significant chronic exposure hazard); 3 (severe acute exposure hazard; onetime overexposure can
result in permanent injury and may be fatal); 4 (extreme acute exposure hazard; onetime
overexposure can be fatal). Flammability Hazard: 0 (minimal hazard); 1 (materials that require
substantial pre-heating before burning); 2 (combustible liquid or solids; liquids with a flash point of 38-
-3 4
[0 (normally stable); 1 (material that can become unstable at elevated
temperatures or which can react slightly with water); 2 (materials that are unstable but do not
detonate or which can react violently with water); 3 (materials that can detonate when initiated or
which can react explosively with water); 4 (materials that can detonate at normal temperatures or
pressures). PERSONAL PROTECTIVE EQUIPMENT CODES: B: Gloves and goggles; C: Gloves,

goggles, rubber apron (appropriate body protection); D: Gloves, goggles, faceshield; rubber apron
(appropriate body protection);. X: Special attention should be given to PPE Selection.

NATIONAL FIRE PROTECTION ASSOCIATION: Health Hazard: 0 (material that on exposure under
fire conditions would offer no hazard beyond that of ordinary combustible materials); 1 (materials that
on exposure under fire conditions could cause irritation or minor residual injury); 2 (materials that on
intense or continued exposure under fire conditions could cause temporary incapacitation or possible
residual
injury); 3 (materials that can on short exposure could cause serious temporary or residual injury); 4
(materials that under very short exposure could cause death or major residual injury). Flammability
Hazard and Reactivity Hazard: Refer to definitions for “Hazardous Materials Identification System”.

FLAMMABILITY LIMITS IN AIR:
Much of the information related to fire and explosion is derived from the National Fire Protection
Association (NFPA). Flash Point – Minimum temperature at which a liquid gives off sufficient vapors
to form an ignitable mixture with air. Autoignition Temperature: The minimum temperature required to
initiate combustion in air with no other source of ignition. LEL - the lowest percent of vapor in air, by
volume, that will explode or ignite in the presence of an ignition source. UEL – the highest percent of
vapor in air, by volume, that will explode or ignite in the presence of an ignition source.

TOXICOLOGICAL INFORMATION:
Possible health hazards as derived from human data, animal studies, or from the results of studies
with similar compounds are presented. Definitions of some terms used in this section are: LD50 -
Lethal Dose (solids & liquids) which kills 50% of the exposed animals; LC50 – Lethal Concentration
(gases) which kills 50% of the exposed animals; ppm concentration expressed in parts of material
per million parts of air or water; mg/m3 concentration expressed in weight of substance per volume
of air; mg/kg quantity of material, by weight, administered to a test subject, based on their body
weight in kg. Data from several sources are used to evaluate the cancer-causing potential of the
material. The sources are: IARC - the International Agency for Research on Cancer; NTP - the
National Toxicology Program, RTECS - the Registry of Toxic Effects of Chemical Substances, OSHA
and CAL/OSHA. IARC and NTP rate chemicals on a scale of decreasing potential to cause human
cancer with rankings from 1 to 4. Subrankings (2A, 2B, etc.) are also used. Other measures of
toxicity include TDLo, the lowest dose to cause a symptom and TCLo the lowest concentration to
cause a symptom; TDo, LDLo, and LDo, or TC, TCo, LCLo, and LCo, the lowest dose (or
concentration) to cause lethal or toxic effects. BEI - Biological Exposure Indices, represent the levels
of determinants which are most likely to be observed in specimens collected from a healthy worker
who has been exposed to chemicals to the same extent as a worker with inhalation exposure to the
TLV. Ecological Information: EC is the effect concentration in water.

REGULATORY INFORMATION:
This section explains the impact of various laws and regulations on the material. EPA is the U.S.
Environmental Protection Agency. WHMIS is the Canadian Workplace Hazardous Materials
Information System. DOT and TC are the U.S. Department of Transportation and the Transport
Canada, respectively. Superfund Amendments and Reauthorization Act (SARA); the Canadian
Domestic/Non-Domestic Substances List (DSL/NDSL); the U.S. Toxic Substance Control Act
(TSCA); Marine Pollutant status according to the DOT; the Comprehensive Environmental
Response, Compensation, and Liability Act (CERCLA or Superfund); and various state regulations.
