This image shows the NFPA 704 “fire diamond,” a standardized symbol used globally to indicate the hazards of dangerous materials. The red quadrant (top) denotes flammability, blue (left) indicates health hazard, yellow (right) represents reactivity/instability, and white (bottom) is reserved for special hazards like oxidizers or water-reactivity. Each section may contain a numerical rating from 0 (minimal hazard) to 4 (severe hazard).

This image is commonly used on safety data sheets (SDS), chemical container labels, facility signage, and occupational safety training materials. It supports user intent related to hazard identification, OSHA compliance, emergency response planning, and workplace chemical safety education.
