Fire Diamond

The NFPA (National Fire Protection Association) Fire Diamond is a symbol used to alert first responders to the hazards involved with a given material. The fire diamond consists of four color-coded quadrants and is based on standards listed in the NFPA document: “Standard System for the Identification of the Hazards of Materials for Emergency Response” and is designed to be easily understood.

Red on the top indicating fire hazard.

Blue on the left indicating health hazard.

Yellow on the right indicating chemical instability hazard.

White on the bottom indicating special hazards.

Fire, health, and instability hazards are rated on a scale from 0 (no hazard) to 4 (severe hazard). Special hazards are listed by symbols specific to the material.
