The National Fire Protection Association (NFPA) hazard identification system uses a color-coded diamond to represent four different hazards. The different colors represent three different types of hazard that may be associated with chemicals:
|Blue indicates health hazard.|
|Red indicates flammability.|
|Yellow indicates reactivity.|
White represents other hazards such as
if a chemical reacts violently with water ( )
or is an oxidizer ( ).
The numbers in the blue, red and yellow diamonds are used to indicate the severity of the hazard for that category:
0 = no or minimal hazard
1 = slight hazard
2 = moderate hazard
3 = serious hazard
4 = extreme hazardCall 800-747-0445 for AssistanceFREE Set-Up of Your Private, Easy-Order Link to YOUR Customized Safety Signs and Labels.(Call For Corporate Purchase Order Account Set-Up)
