NFPA 704 Hazard Diamond Guide - Understanding Chemical Risk Ratings #141963 (License: Personal Use)

This standardized hazard identification system, developed by the National Fire Protection Association, helps emergency responders and workers quickly assess risks associated with hazardous materials. Each quadrant is rated 0-4, with 4 indicating the highest level of danger; the white section may include symbols like “W” for water-reactive or “OX” for oxidizers. The outer border includes fields for chemical name, manufacturer, date received, and emergency contact number.

Used on chemical containers, storage areas, and safety data sheets in industrial, laboratory, and emergency response settings; supports OSHA compliance and rapid hazard assessment during incidents.
