NFPA 704 Hazard Diamond - Understanding Chemical Risk Ratings #2218546 (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 rated numerically (0-4) to indicate severity, enabling first responders and workers to assess risks at a glance during emergencies or routine handling.

Used on chemical containers, storage areas, and safety data sheets to support OSHA compliance and emergency response planning; matches user intent for hazard identification, workplace safety training, or regulatory reference.
