NFPA Guide
The National
Fire Protection Association (NFPA) diamond is an easily reconizable
system for identifying the health and physical hazards associated
with specific chemicals. It was originally developed to aid fire
fighters responding to emergencies in industrial settings where
dangerous chemicals were present. Today, it is used in RTK labels
and HazCom programs in a variety of work environments.
The NFPA Diamond
uses color codes to identify Health risks (in blue), Flammability
(in red), Instability (in yellow), and Special Hazards (in white).
It rates the severity of the hazard on a scale of 0 to 4 with 4
being the most severe.
