NFPA 704 Hazard Diamond Guide - Understanding Chemical Risk Symbols #3731026 (License: Personal Use)

This image displays the standard NFPA 704 hazard identification system, a diamond-shaped label divided into four colored sections: red (top) for flammability, blue (left) for health hazard, yellow (right) for reactivity, and white (bottom) for special hazards such as oxidizers or water-reactivity. Each quadrant contains a number (0-4) or symbol indicating severity; here, letters “S”, “M”, “D”, and “S” appear, suggesting placeholder or illustrative use rather than standard numeric ratings. The system is widely used in industrial, laboratory, and emergency response settings to enable rapid risk assessment.

This image is typically used on safety training pages, OSHA/NFPA compliance resources, chemical handling guides, and emergency response manuals. It serves users seeking to interpret hazard labels on containers, storage areas, or facility signage-matching intent around workplace safety, regulatory compliance, and hazard communication.
