NFPA 704 Hazard Diamond - Understanding Chemical Risk Ratings #2218560 (License: Personal Use)

This standardized safety symbol, defined by the National Fire Protection Association (NFPA) in standard 704, provides instant visual information about hazardous materials. Each quadrant-red (top), blue (left), yellow (right), and white (bottom)-represents a specific hazard category rated from 0 (minimal) to 4 (severe). It is widely used on chemical containers, storage areas, and emergency response signage to support rapid risk assessment.

This image is typically used on safety training pages, OSHA/NFPA compliance resources, chemical handling guides, and emergency response protocols. It serves users seeking to interpret or apply hazard communication standards in industrial, laboratory, or first-responder contexts.
