This image displays the NFPA 704 hazard diamond, a standardized system for communicating chemical hazards. The red quadrant indicates flammability, blue denotes health hazards, yellow signals reactivity, and the white section is reserved for special hazards such as oxidizers or water-reactive substances. Each color corresponds to a numerical rating from 0 (minimal hazard) to 4 (severe hazard).

Used on chemical containers, safety data sheets, and facility signage to quickly convey risk levels to emergency responders and workers; matches user intent for safety training, regulatory compliance, or hazard identification reference.
