4 Fire, Explosion Hazard And Reactivity Data
This section contains the flash point and flammable limits of the material.
It also includes how to fight fires if the material catches on fire. Key terms
in this section include:
•
Flashpoint: The temperature at which a liquid will give off enough
flammable vapor to ignite.
•
Flammability and ignitability are usually defined by the flash point.
•
Lower Flammable Limit (LFL or LEL): The lowest concentration
that will produce a fire or flash when an ignition source is present.
•
Upper Flammable Limit (UFL or UEL): The vapor concentration in
air above which the concentration is too rich to burn.
•
NFPA Codes: The National Fire Protection Association (NFPA) has a
system to rate the degree of hazards presented by a chemical. These
codes are usually placed in a colored diamond. The codes range from
0 for minimal hazard to 4 for extreme hazard. They are grouped into
the following hazards: health (blue), flammability (red), reactivity
(yellow), and special hazards (white).
5 Health Hazard Data
This section describes different ways the chemical can enter your body
(ingestion, inhalation, skin contact). It also gives acute (immediate) and
chronic (long-term) health effects. If the material causes cancer or genetic
damage, it is identified in this section.
6 Precautionary Measures
This section contains special precautions for the material. These may
include special storage instructions, handling instructions, conditions to
avoid, and protective equipment required to use this material safely.
7 First Aid
First aid instructions for exposures to the chemical are given in this
section. Be sure to read this section before inducing vomiting in a victim.
Some chemicals are better treated by not inducing vomiting. Seek prompt
medical attention for all chemical exposures.
8 Spill And Disposal Procedures
This section tells about safe work practices for cleaning up and disposing
of spilled material. Please refer to the Waste Management section of this
manual. Final determination of proper and legal disposal options is the
responsibility of the waste generator. Be sure you know the federal, state,
and local laws that apply to your facility.
