The NFPA Hazard Diamond
Captions available
The idea
The NFPA hazard diamond is a four-color symbol for a chemical's fire, health, reactivity, and special hazards, zero to four.
In practice
A container with a high red-diamond number signals a low flash point and fire hazard at a glance.
Where people slip
The diamond communicates a hazard's level, not how to handle it — that belongs to trained staff.
