The National Fire Protection Association (NFPA) hazard system for chemical materials
The National Fire Protection Association (NFPA) has developed a system for indicating the health, flammability, reactivity and special hazards for many common chemicals through use of the NFPA 704 Diamond.

This substance is extremely flammable, volatile and explosive.
|May Detonate |
Substances may explode at normal temperatures and pressures.
|SPECIFIC HAZARD |

Capable of detonation or explosion by heat, shock or water.
|Dangerous: exposure to this substance would be hazardous to health.||Flash Point Below 200 F |
Moderately heated conditions may ignite this substance.
Violent chemicals changes are possible at normal temperatures or pressures or when mixed with water.
|Irritation or minor injury would result from exposure to this substance.||Flash Point Above 200 |
