NFPA 704 Hazard Diamond Explained | Safety Symbol Guide #2218568 (License: Personal Use)

This image displays the NFPA 704 hazard identification system-a diamond divided into four colored sections: red (flammability), blue (health hazard), yellow (reactivity), and white (special hazards like oxidizers or water-reactive materials). Each quadrant uses a numerical rating from 0 (minimal hazard) to 4 (severe hazard) to communicate risks quickly in emergency response scenarios. The symbol is standardized by the National Fire Protection Association for use on chemical containers, storage areas, and transport vehicles.

Used on chemical labels, safety data sheets, industrial facilities, and emergency response guides; matches user intent to identify, interpret, or comply with OSHA/NFPA safety standards for hazardous materials handling.
