NFPA 704 Hazard Diamond - Understanding Chemical Risk Ratings #131647 (License: Personal Use)

This image shows the standard NFPA 704 hazard identification system-a diamond divided into four colored sections: red (top) for flammability, blue (left) for health hazard, yellow (right) for reactivity/instability, and white (bottom) for special hazards like oxidizers or water reactivity. Each quadrant is typically numbered 0-4 to indicate severity, though this version shows only the base colors without numerical ratings. It’s widely used on chemical containers, storage areas, and safety data sheets to enable rapid risk assessment by emergency responders and workers.

This image is used on safety training pages, OSHA/NFPA compliance guides, chemical handling manuals, and emergency response resources. It serves users seeking to interpret or implement standardized hazard communication, especially in industrial, laboratory, or fire safety contexts.
