Hazards of Chemicals…
There are 2 basic types of chemical hazards
– Physical Hazards
– Health Hazards
The first rule of chemical safety is…
"Know what you are working with and
how to protect yourself and others“
Physical Hazards…
Chemicals are classified as having Physical
Hazards if they are
 Explosive
 Compressed Gas
 Combustible Liquids
 Flammable
 Unstable
 Water Reactive
 Oxidizers
Physical Hazards…
Some chemicals may be safe by themselves,
but become dangerous when in contact with
other substances.
Chemicals with Physical Hazards…
Used only by trained employees
Stored in a safe manner
Never mixed with other chemicals unless by
an approved procedure
Health Hazards
Chemicals are classified as being a health
hazard if they:
Can cause cancer
Are poisonous (toxic)
Cause harm to your skin, internal organs, or
nervous system
Are corrosive - such as acids
Cause allergic reactions after repeated
exposure
Chemicals can enter the body through:
your lungs if you breath
fumes, mists or dust
your skin if liquid or dust
touches or spills on you or
splashes in your eyes
your mouth if you eat after
handling chemicals
accidental swallowing of a
chemical
Health Effects…
Some chemicals affect
specific organs such
as your kidneys, liver,
reproductive or
nervous system.
Our Written Hazard Communication
Program provides…
Written information on hazards
Lists chemicals we use and their
hazards
System for ensuring chemicals are
labeled
Means to ensure we have an Material
Safety Data Sheet (MSDS) for each
chemical
Our Written Hazard
Communication Program…
Lists who is responsible for the program
Provides chemical specific safety training
methods
Tells you where to find chemical safety
information
You can see a copy of our written
program by asking you supervisor
Labeling of Chemicals…
Chemical labels provide
information on Identity,
Hazards and Safe Use
All chemical containers are
labeled by the
manufacturer
Our company may place
additional labels on the
containers
Labeling of Chemicals…
If chemicals are placed in another
container, this new container must
have a a label placed on it.
All containers must be properly
labeled
Uniform Labeling System…
Our university “Uniform Labels” are
used to ensure we have one labeling
system.
These may be placed on containers
when chemicals are delivered to us
or chemicals are transferred to
other containers
2 Basic “Uniform Labels”
HMIS - Hazardous Material Identification
System
NFPA - National Fire Protection Association
Both types must identify the
chemical name and hazards
Uniform Labels…
Pictures may be used to
identify hazards and
required protection
This information may also
be on the manufacturer’s
label
HMIS and NFPA labels are very similar
Both use colored boxes to identify specific
hazards
Numbers or codes in the boxes tell you the
hazard value
higher number = higher hazard
NFPA and HMIS Label Colors
Red - Fire Hazard
Blue - Health Hazard
Yellow - Reactivity Hazard - explosive,
unstable
White - Special Hazards - corrosive,
radioactive, water reactive, acid
NFPA Label..
The purpose of the NFPA 704
labeling system is to provide a
way of quickly identifying the
various fire related hazards
associated with a particular
material. The NFPA 704
"diamond" is commonly
found on bulk storage
containers, but is also widely
used on chemical containers
and the MSDS.
NFPA Flammability Codes
4 Materials that will rapidly or
completely vaporize at atmospheric
pressure and normal ambient
temperature, or that are readily
dispersed in air and that will burn
readily. Liquids with a flashpoint
below 73ºF and a boiling point below
100ºF.
NFPA Flammability Codes
3 Liquids and solid that can be ignited under
almost all ambient temperature conditions.
Liquids with a flashpoint below 73ºF and a
boiling point above 100ºF or liquids with a
flashpoint above 73ºF but not exceeding
100ºF and a boiling point below 100ºF.
NFPA Flammability Codes
2 Materials that must be moderately heated or
exposed to relatively high ambient
temperatures before ignition can occur.
Liquids with flashpoint above 100ºF but not
exceeding 200ºF.
NFPA Flammability Codes
1 Materials that must be preheated before
ignition can occur. Liquids that have a
flashpoint above 200ºF.
0 Materials that will not burn.
NFPA Health Hazard Codes
4 Materials that on very short
exposure could cause death or
major residual injury.
3 Materials that on short exposure
could cause serious temporary or
residual injury.
NFPA Health Hazard Codes
2 Materials that on intense or
continued, but not chronic
exposure could cause
incapacitation or possible
residual injury.
NFPA Health Hazard Codes
1 Materials that on exposure
would cause irritation but only
minor residual injury.
0 Materials that on exposure
under fire conditions would
offer no hazard beyond that of
ordinary combustible material.
NFPA Reactivity Hazard Codes
4 Materials that in themselves are readily
capable of detonation or of explosive
decomposition or reaction at normal
temperatures and pressures.
NFPA Reactivity Hazard Codes
3 Materials that in themselves
are capable of detonation or
explosive decomposition or
reaction but require a strong
initiating source or which
must be heated under
confinement before initiation
or which react explosively
with water.
NFPA Reactivity Hazard Codes
2 Materials that readily undergo violent
chemical change at elevated temperatures
and pressures or which react violently with
water or which may form explosive
mixtures with water.
NFPA Reactivity Codes
1 Materials that in themselves are normally
stable, but which can become unstable at
elevated temperatures and pressures.
NFPA Reactivity Codes
0 Materials that in themselves are normally
stable, even under fire exposure conditions,
and which are not reactive with water.
NFPA Special Hazard Codes
ACID = Acid Products
ALK = Alkali or Bases
COR = Corrosive Products
OX = Oxidizer
W =Reacts with water
Radioactive
What do I do…
if there is no label or I cannot read the
label?
