NFPA 704 Hazard Diamond - Understanding Chemical Risk Symbols #2218561 (License: Personal Use)

This image displays the standard NFPA 704 hazard identification system-a diamond divided into four colored sections: red for flammability, blue for health hazard, yellow for reactivity, and white for special hazards like oxidizers or water reactivity. Each quadrant may contain a numerical rating (0-4) indicating severity, enabling rapid risk assessment by first responders and workers. The symbol is widely used on chemical containers, storage areas, and facility signage.

Used on chemical labels, safety data sheets, and industrial facility signage to support OSHA compliance and emergency response; targets safety officers, lab technicians, firefighters, and regulatory personnel seeking quick hazard recognition.
