stabilized, cleared-up, or in any other manner processes or
handled with the ultimate goal of making the site safer for people
or the environment.

DECONTAMINATION - means the removal of hazardous
substances from employees and their equipment to the extent
necessary to preclude the occurrence of foreseeable adverse
health affects.
EMERGENCY RESPONSE - means a response effort by
employees from outside the immediate release area or by other
designated responder to an occurrence which results, or is likely to
result, in an uncontrolled releases of a hazardous substance.

FACILITY - means (a) any building, structure, installation,
equipment, pipe or pipeline, well, pit, pond, lagoon, impoundment,
ditch, storage container, motor vehicle, rolling stock, or aircraft, or
(b) any site or area where a hazardous substance has been deposited,
stored, disposed of, or placed, or otherwise come to be located.
HAZARDOUS MATERIALS RESPONSE (HAZMAT) TEAM
- means an organized group of employees, designated by the
employer, who are expected to perform work to handle and control
actual or potential leaks or spills of hazardous substances requiring
possible close approach to the substance.

HAZARDOUS WASTE OPERATION - means any operations
conducted within the scope of 29 CFR 1910.120.

or a pathogen for which there is statistically significant evidence
based on at least one study conducted in accordance with
established scientific principles that acute or chronic health effects
may occur in exposed employees.
IMMEDIATELY DANGEROUS TO LIFE OR HEALTH -
means an atmospheric concentration of any toxic, corrosive or
asphyxiate substance that poses and immediate threat to life or would
cause irreversible or delayed adverse health effects or would
interfere with an individual’s ability to escape from a dangerous
atmosphere.

OXYGEN DEFICIENCY - means that concentration of oxygen
by volume below which atmosphere supplying respiratory
protection must be provided. It exists in atmospheres where the
percentage of oxygen by volume is less than 19.5 percent oxygen.

Air’s density is 1.29 g/L or 0.011 lb/gallons.
VD greater than 1.0, the
vapors are heavier than air
and lay in low areas.
VD less than 1.0, the
vapors are lighter than air
and will rise.

- pH. THE pH OF A LIQUID IS THE NUMERICAL MEASURE OF ITS RELATIVE
ACIDITY OR ALKALINITY. THE RANGE IS FROM 0 - 14 WITH A NEUTRAL

PARACELSUS
(1493 - 1541)

TOXICOLOGYTOXICOLOGY
TOXIN -TOXIN - Any of a group of poisonous, usually unstable
compounds generated by microorganisms,
plants or animals. Certain toxins are produced
by specific pathogenic microorganisms and are
the causative agents in various diseases, as tetanus,
diphtheria, etc.
TOXICITYTOXICITY- The effect a specific quantity or dosage of a
specific toxin (Chemical) has on a living
microorganism. This is not an absolute!

TOXICITY
INGESTION
ABSORPTION
INHALATION
Swallowing of a substance through the
mouth and into the stomach. Generally
followed by its entrance into the small
intestine.
Entering the body through the skin.
Substances that absorb through the skin
sometime further assimilate into the
blood system.
Breathing causes us to inhale substances
which in return travels en route to the
lungs. Our lungs are so rich in blood
vessels that any substance inhaled into
the lungs are readily absorbed into the
bloodstream.

TOXIC EFFECTS
ACUTE - Is generally regarded as a severe injury caused
by a one time, relatively short exposure to a chemical
substances harmful to the human body.
CHRONIC - Is an injury or disease that manifests itself after a
relatively long period of time has elapsed since the
initial exposure to the substance causing some type
of ailment.
LATENT - Is an injury or disease that remains undeveloped until
an incubation period has elapsed. The period of time
could be hours, days, months or years.
IRRITANT - Is a chemical substance that injures the tissues of the
respiratory system and lungs, thereby causing
inflammation of the respiratory passages.

AFFECTING FACTORS

LETHAL DOSE - LD50
The LD50 is the amount of a material that, when administrated
to laboratory animals, kill half of them. The expression is made
in milligrams of the substance administered per body weight of
the animal expressed in kilograms (mg/kg).
When extrapolated to humans, the lethal dose of an average
person who weighs w kilograms is LD50 x w.

LETHAL CONCENTRATION - LC50
The LC50 is the concentration of a material that, normally
express as parts per million (ppm) by volume, that when
administrated to laboratory animals, kill half of them during the
period of exposure.

THRESHOLD LIMIT VALUE - TLV
The TLV is the upper limit of a toxin concentration to which an
average healthy person may be repeatedly exposed on an all-day,
everyday basis without suffering adverse health effects.
Gaseous substances in air, the TLV is usually express as parts
per million (ppm).
Fumes or mist in air, it is expressed in milligrams per cubic meter
(mg/m3
).
TLV values are set by the American Conference of Governmental
Industrial Hygienist (ACGIH).

IMMEDIATELY DANGEROUS TO
LIFE AND HEALTH - IDLH
An IDLH level represents a maximum concentration from which
one could escape within 30 minutes without experiencing any
escape-impairing symptoms or any irreversible adverse health
effects.
IDLH levels are published for many substances by OSHA
and NIOSH.
In practice, when the concentration of a toxic substance in a
given area is known, IDLH levels may be used for determining
whether self-contained breathing apparatus is needed when
entering the area. If the concentration exceeds the IDLH level,
positive- demand, self-contained breathing apparatus should be
used.

TLV - Threshold Limit Value: One of three categories of chemical
exposure levels - TLV-TWA, TLV-STEL or TLV-C.
TLV-TWA - Threshold Limit Value Time-Weighted Average: The
time weighted average concentration for a normal 8-hour
workday and a 40 hour work week to which nearly all
workers may be repeatedly exposed without adverse effect.
Should be used as an exposure guide rather than an absolute.
TLV-STEL - Threshold Limit Value - Short Term Exposure Limit: A
15 minute time-weighted average exposure that should not be
exceeded at any time during the work day.
TLV-C - Threshold Limit Value- Ceiling: The concentration that
should not be exceeded even instantaneously.

4 TYPES OF PROTECTION
LEVEL - ALEVEL - A
LEVEL - BLEVEL - B
LEVEL - CLEVEL - C
LEVEL - DLEVEL - D

Level A is used when the greatest level of skin, respiratory and
eye protection is required.
 Level A protection should be used when:
The hazardous substance has been identified and requires the highest level of
protection for skin, eyes and the respiratory system based on either the
measured (or potential for) high concentration of atmospheric vapors, gases, or
particulate; or the site operations and work functions involve a high potential
for splash, immersion, or exposure to unexpected vapors, gases, or particulate
of materials that are harmful to skin or capable of being absorbed through the
skin.
Substances with a high degree of hazard to the skin are known or suspected to
be present, and skin contact is possible.
Operations are being conducted in confined, poorly ventilated areas, and the
absence of conditions requiring Level A have not yet been determined.
LEVEL - A PROTECTIONLEVEL - A PROTECTION

LEVEL - B PROTECTIONLEVEL - B PROTECTION
Level B is used when the highest level of respiratory protection is necessary
but a lesser level of skin protection is needed.
 Level B protection should be used when:
The type and atmospheric concentration of substances have been identified
and require a high level of respiratory protection but less skin protection.
The atmosphere contains less than 19.5 percent oxygen.
The presence of incompletely identified vapors or gases is indicated by a
direct reading organic vapor detection instrument, but vapors and gases are
not suspected of containing high levels of chemicals harmful to skin or
capable of being absorbed through the skin.
NOTE: This involves atmospheres with IDLH (Immediately Dangerous to
Life and Health) concentrations of specific substances that present severe
inhalation hazards and that do not represent a severe skin hazard.

LEVEL - C PROTECTIONLEVEL - C PROTECTION
Level C is used when the concentration(s) and type(s) of airborne
substance(s) is known and the criteria for using air purifying respirators
are met.
 Level C protection should be used when:
The atmospheric contaminants, liquid splashes, or other direct contact will
not adversely affect or be absorbed through any exposed skin.
The types of air contaminants have been identified, concentrations
measured, and an air purifying respirator is available that can remove the
contaminants.
All criteria for the use of air purifying respirators are met.

LEVEL - D PROTECTIONLEVEL - D PROTECTION
Level D is used for nuisance contamination only. A work uniform affording
minimal protection.
 Level D protection should be used when:
The atmosphere contains no known hazards.
Work functions preclude splashes, immersion, or the potential for
unexpected inhalation of or contact with hazardous levels of any chemicals.

FIRST AID

If you work with hazardous chemicals, there could be a danger
in the air. You can not always see or smell the hazards, but
dust, smoke, fog, mist, fumes, gases, vapors and sprays can be
very hazardous to your health and safety. So, you need to ask
yourself the following questions?
1. What are the exposure limits allowed for the particular
contaminants?
2. Have the hazard levels in your work area been measured?
3. Do you have the correct amount of oxygen in your work
area?
4. Are you trained to use and wear a Respirator?
Remember - Respirators play a big part in your Safety.
DO I NEED A RESPIRATOR?

Types of Respirators -
Air-purifying or Filtering - The APR is used
where there is enough oxygen present ( approx.
20%), but the air in the area is contaminated with
gases, vapors, and dust. These respirators filter
out dangerous materials or diverts air through a
chemical filter.
WARNING - Some substances can not be safely
filtered out requiring you to wear a Air - Supplied
Respirator.

Supplied-Air Respirators - The SAR is used
whenever there is not enough oxygen in a confined
space or area and the concentration of the airborne
substances present is immediately dangerous to life
and health (IDLH).
All respirators must be approved for the contaminant
for which the employee is exposed too. Approval
is done jointly by the Mine Safety and Health
Administration of the Department of Labor and the
National Institute for Occupational Safety and
Health (NIOSH) of the Department of Health and
Human Services.

Self - Contain Breathing Apparatus (SCBA) -
SCBA uses a source of breathable air carried by the
wearer. Although this greatly enhances the mobility
of the wearer it limits the duration of protection.
At a moderate work rate, using approximately 40
liter minute volume, most SCBA used in hazardous
situations have a rated duration of 30 to 60
minutes.
SCBA consist of the following: Face piece, Breathing
tube, Air supply tube, Regulator, Exhalation valve and
Air Cylinder and valve.

Respirators places a strain on the wearer’s cardiovascular
system. All workers must exert a greater degree of effort to
inhale and exhale when wearing a respirator.
Some people are claustrophobic and cannot wear respirators.
OSHA requires that anyone assigned a task requiring the use
of respirators be examined and certified as being able to safely
wear the respirator. Furthermore, the worker and supervisor
must have a basic understanding of respirator selections,
operations, fitting, limitations and maintenance.
THE PHYSICAL REQUIREMENTS

PROPER FITTING
The proper fitting of a respirator is determined by a fit
tests and seal checks. Fit tests can be “Qualitative” or
“Quantitative”. Some OSHA Standards have specific
requirements for fit testing.

Spill Control
The control of any inadvertent release of hazardous
materials can be as simple as turning off a valve,
turning a drum on its side, to performing a complete
day of clean-up in a totally encapsulating suit.

CONTAINMENT
Any procedures taken to keep the material in its original
container, Contaminate activities are generally undertaken
by a Hazardous Material Technician or Specialist and
require many hours of training and practice. Your
imagination is a good place to begin to develop containment
methods.
Super glue, underwater patching materials for boats and fast
setting materials for casts are just some of the simple
examples.

CONFINEMENT
Any procedures taken to keep all the material in a defined
area. These activities will vary from plant to plant and will be
determined by the company emergency response plan. Spills
or releases can be confined by our A, B, C, D materials.

DECONTAMINATION is a very important part
of Training. Emergency response workers at the
First Responder, Operations Level, Hazardous
Materials Technician, Hazardous Materials
Specialist, and On-Scene Incident Commander
levels are all required to know and understand
decontamination procedures.
DECONTAMINATION

DECONTAMINATION
Contamination is derived from the Latin verb meaning
“To Touch”, while the prefix De means “Do the
opposite of.”
So we can not stress this importantly enough, “Do Not
Touch” these materials.
TOUCH

DECONTAMINATION
Contamination at hazardous waste sites can occur to people,
vehicles, equipment, buildings and to the environment, both
plants and animals. By avoiding contamination through proper
positioning of people, apparatus and equipment, you eliminate
the need to decontaminate.
Decontamination is performed whenever any the following
conditions are present:
 When there is obvious contamination by a know substance.
 When there is suspected contamination by a know substance.
 When there is likelihood of exposure to a deadly substance.
 When you don’t want to spread the contamination.
 When you want to protect the environment.

GOAL OF
DECONTAMINATION
Is to minimize the potential harm to people and the
environment by eliminating or reducing the hazards
of the chemical contaminant.

METHODS OF
DECONTAMINATION
 DILUTION
 ABSORPTION
 DEGRADATION
 ISOLATION
 NEUTRALIZATION
 DISPOSAL

DILUTION
THE THINNING OUT OR WEAKENING OF A
SUBSTANCE BY ADDING ANOTHER
MATERIAL, CALLED A DILUTENT. DILUTION
IS A VALID STEP IN DECONTAMINATION,
BUT THE END MATERIAL WILL STILL HAVE
TO BE DISPOSED OF.

ABSORPTION
THE PROCESS WHERE ONE SUBSTANCE
COMBINES WITH ANOTHER BY
MOVING INTO IT OR ENTERING THE
INTERIOR OF THE OTHER SUBSTANCE.
WHEN ABSORBENT ARE USED IN THE
DECONTAMINATION PROCESS, THE
COMBINED MATERIAL MUST BE
CONSIDERED AND HANDLED AS
CONTAMINATED.

DEGRADATION
THE MOLECULAR BREAKDOWN OF A
MATERIAL. IN THE CASE OF A CONTAMINANT
IT CAN RENDER THE MATERIAL LESS
HAZARDOUS. THE PROCESS CAN BE USED IN
DECONTAMINATION, BUT THE EXTENT OF
DEGRADATION MUST BE MONITORED AND
VERIFIED.

ISOLATION
THE ESTABLISHMENT OF A BOUNDARY OR
PERIMETER WHERE A MATERIAL IS
LOCATED OR PLACED, AND WHERE ENTRY
IS RESTRICTED TO UNAUTHORIZED
PERSONNEL. ISOLATION IS NOT ALWAYS
ACHIEVABLE OVER THE LONG TERM, BUT
IT DOES PROVIDE A TEMPORARY METHOD
OF DEALING WITH A CONTAMINATED
SUBSTANCE.

NEUTRALIZATION
THE PROCESS THAT OCCURS WHEN
ACID AND BASES NEUTRALIZE EACH
OTHER; I.E. THE CHARACTERISTIC
PROPERTIES OF BOTH ACID AND AND
BASES DISAPPEAR OR HAVE A NEUTRAL
VALUE. WHERE IT CAN BE ACHIEVED
NEUTRALIZATION IS AN EFFECTIVE
TECHNIQUE IN DECONTAMINATION.

DISPOSAL
THE FINAL STEP IN A PROCESS WHEREBY A
SUBSTANCE IS TRANSFERRED TO AN
AUTHORIZED PARTY, OR TO A FINAL
RESTING PLACE.

LEVEL 1
DECONTAMINATION
Used when the nature of the incident indicates
that there is at least a possibility that an
exposure has occurred but no one is certain
that it has. An example would be if a
reconnaissance team entered a waste site, in
appropriate clothing and SCBA, to identify the
markings on a leaking 55 gallon drum.
3 LEVELS OF DECON

LEVEL 2
DECONTAMINATION
Used when you can physically see that
contamination of clothing has occurred, but the
skin has not been exposed. An example would be
a drum is rolled over and you step in the spilled
liquid. No one on the team experiences skin
contact.
3 LEVELS OF DECON

LEVEL 3
DECONTAMINATION
Used whenever the chemical has come into
contact with the skin. An example would be a
member of the team is splashed by the liquid and
the liquid has eaten a small hole in the clothing
and is burning the skin.
3 LEVELS OF DECON

DECONTAMINATION
CORRIDOR CRITERIA
 Topography - The decon corridor should be located on a
level surface, upwind and upgrade from the site.
 Distance from spills - A minimum of 100 feet shall be
maintained between the decon area and the spill for minor
incidents. 500 feet for major incidents.
 Perimeters - An inner and outer security perimeter will be
established. The entrance into the hot zone must be a
controlled access point.
 Markings - Use stakes or cones and brightly colored
perimeter tape to clearly identify the decon corridor.

 REMEMBER, YOU CONTROL YOUR FACILITY OR AREA!
 REVIEW THEIR PROCEDURES WITH THEM BEFORE
STARTING THE JOB!
 DETERMINE THEIR SAFETY PERFORMANCE RECORD!
 DETERMINE WHO IS IN CHARGE OF THEIR PEOPLE!
 DETERMINE HOW THEY WILL AFFECT YOUR EMPLOYEES!
TIPS FOR USING CONTRACTORS

OSHA'S PERCEPTION
OF A SUCCESSFUL PROGRAM
1. DETAILED WRITTEN HAZARD ASSESSMENTS
2. DETAILED WRITTEN SAFETY PROCEDURES
3. EXTENSIVE EMPLOYEE TRAINING PROGRAMS
4. PERIODIC REINFORCEMENT OF TRAINING
5. SUFFICIENT DISCIPLINE REGARDING IMPLEMENTATION
6. FOLLOW-UP

WORK AT WORKING SAFELY
Training is the key to success in managing safety in the
work environment. Attitude is also a key factor in
maintaining a safe workplace. Safety is, and always will
be a team effort, safety starts with each individual
employee and concludes with everyone leaving at the
end of the day to rejoin their families.
