HAZARD COMMUNICATION
• Chemicals are certainly useful, on the job
and off. But as we all know by now, many
chemicals are hazardous to your health if
you are exposed to too much of them or if
the exposure is too direct.

The Hazard Communication Standard is specifically concerned with
chemical hazards—the chemical's physical and health risks to people.
A chemical may have three basic physical hazards:
1.
Fire. You have to know if a chemical could, in a liquid, gas, or
vapor form, catch fire and under what circumstances.
2.
Explosion. You also have to know if there are circumstances
under which a chemical might explode.
3.
Reactivity. This is the potential of a chemical to catch fire or
explode if it's combined with other chemicals or with water or air. You
need to know what the chemical should be kept away from and what
situations to avoid.

Health Hazard
4
Very short exposure could cause death or serious residual injury even
though prompt medical attention was given.
3
Short exposure could cause serious temporary or residual injury even
though prompt medical attention was given.
2
Intense or continued exposure could cause temporary incapacitation or
possible residual injury unless prompt medical attention is given.
1
Exposure could cause irritation but only minor residual injury even if
no treatment is given.
0
Exposure under fire conditions would offer no hazard beyond that of
ordinary combustible materials.
7
Flammability
4
Will rapidly or completely vaporize at normal pressure and
temperature, or is readily dispersed in air and will burn readily.
3
Liquids and solids that can be ignited under almost all ambient
conditions.
2
Must be moderately heated or exposed to relatively high temperature
before ignition can occur.
1
Must be preheated before ignition can occur.
0
Materials that will not burn.
8
Instability1
4
Readily capable of detonation or of explosive decomposition or
reaction at normal temperatures and pressures.
3
Capable of detonation or explosive reaction, but requires a strong
initiating source or must be heated under confinement before initiation,
or reacts explosively with water.
2
Normally unstable and readily undergo violent decomposition but do
not detonate. Also: may react violently with water or may form
potentially explosive mixtures with water.
1
Normally stable, but can become unstable at elevated temperatures and
pressures or may react with water with some release of energy, but not
violently.
0
Normally stable, even under fire exposure conditions, and are not
reactive with water.
9
ACID
This indicates that the material is an acid, a corrosive
material that has a pH lower than 7.0
ALK
This denotes an alkaline material, also called a base. These
caustic materials have a pH greater than 7.0
COR
This denotes a material that is corrosive (it could be either
an acid or a base).
This is a another symbol used for corrosive.
10
The skull and crossbones is used to denote a poison or
highly toxic material. See also: CHIP Danger symbols.
The international symbol for radioactivity is used to
denote radioactive hazards; radioactive materials are
extremely hazardous when inhaled
Indicates an explosive material. This symbol is
somewhat redundant because explosives are
easily recognized by their Instability Rating.
11
You also have a right to know about any health hazards, which
can be anything from a skin rash to lung cancer.
The Standard makes sure you are informed about the possible
health hazards of any given chemical, the symptoms to watch out
for, and any existing medical condition that the chemical might
make worse.
12
You should be able to identify the hazards of any chemical before you
use it with two key Hazard Communication tools:
•
Container labels have to provide you with basic information
on the chemical's hazards and on the basic procedures and protective
equipment you should use when working with it. The label probably
also has basic handling and storage instructions and some first-aid
information.
•
Material safety data sheets have all the details—everything
you ever considered knowing about the chemical, its hazards, and
instructions for safe handling, use, disposal, and storage. There is also
information on what to do if the chemical spills or leaks and first-aid
instructions to follow in the event of an accident.

What Do I Do If I Am Exposed to
Any Chemical On Campus?
• 1. Notify your Supervisor immediately
• 2. ID the chemical and call 2911—NOT
911 via your cell phone
• 3. Render First Aid measures
• 4. Have a Public Safety Report taken by an
officer for any injury RIGHT AWAY
22
What If I Smell A Strange Odor on
Campus?
• 1. Make sure it isn’t caused by something
in your office or directly outside FIRST
• 2. Call X2911 and report it…NOT the Safety
Office
• **Many reports are from cigarette smoking
outside offices or lawnmowers—fumes are gone
by the time officers arrive.
• Is this a danger to me??
• Parking garages…
23
CONCLUSION
Always start your preparation for a job involving a hazardous
chemical with these three steps:
1.
Read the container label.
2.
Read the material safety data sheet.
3.
Follow the instructions and precautions on the material
safety data sheet.
