<strong>Association</strong> (NFPA) Diamond<br />
The NFPA Diamond is a labeling system that incorporates<br />
the use <strong>of</strong> four diamonds combined in one central diamond.<br />
NFPA 704 M is a standardized system that uses numbers<br />
and colors to define the hazards <strong>of</strong> a material. The diamond-shaped<br />
design displays four color and hazard combinations<br />
similar to the HMIS systems:<br />
• Health (blue)<br />
• Flammability (red)<br />
• Reactivity (yellow)<br />
• Special Information (white)<br />
To indicate the degree <strong>of</strong> the hazard presented by the<br />
material, the numbers from 0 - 4 are used. The number<br />
four (4) indicates the maximum or most severe hazard.<br />
NFPA ratings for individual chemicals can be found in the<br />
NFPA “Guide to Hazardous Materials”.<br />
