NFPA 704 Hazard Diamond Guide - Understanding Chemical Risk Ratings #2218634 (License: Personal Use)

The image displays a standard NFPA 704 hazard identification diamond used in occupational safety to communicate chemical risks at a glance. Each quadrant conveys critical information: red for health hazard (0 = minimal), blue for flammability (3 = short exposure hazard), yellow for reactivity (2 = violent reaction possible), and white for special hazards (W = reacts with water). This visual system supports rapid risk assessment in labs, warehouses, and emergency response scenarios.

Used on chemical containers, storage cabinets, and facility signage to inform workers, first responders, and safety personnel about immediate hazards; matches user intent for hazard recognition, OSHA compliance, or safety training.
