•
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).
This section describes the pathways by which the chemical can enter your body
(i.e., 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 stated in this section.
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.
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.
This section explains safe practices for cleaning up and disposing of spilled
material. For more information, see Section 4.3 Hazardous Waste on page 55. The
waste generator is ultimately responsible for meeting the federal, state, and
local laws that apply to his facility.
Domestic and International shipping information is provided in this section. It
gives shipping name, hazard class, and ID number of the product.
This section lists the reference materials used to write the MSDS.
Following the Reference section, the product will be listed as having SARA 313
chemicals or California Proposition 65 List Chemicals, if applicable. Also found
here is any special information about the product.
The Occupational Safety and Health Administration (OSHA) enforces laws
controlling exposure to hazardous chemicals in laboratories. These regulations
are in Title 29 CFR 1910.1450. The regulations apply to all employers who use
hazardous chemicals, and require employers to develop and use a written
Chemical Hygiene Plan and to appoint a qualified person as the Chemical
Hygiene Officer.
