NFPA 704 Hazard Diamond Chart - Health, Flammability, and Reactivity Ratings #126436 (License: Personal Use)

The image displays a standard NFPA 704 hazard identification diamond divided into four colored quadrants-though the white quadrant is omitted here-showing numerical ratings for health (blue, 1), flammability (red, 1), and reactivity (yellow, 0). Each number corresponds to a specific hazard level on a scale from 0 (minimal) to 4 (severe), used widely in industrial, laboratory, and emergency response settings. The absence of the white quadrant suggests this is a simplified or illustrative version focusing only on the primary hazard categories.

This image is typically used in safety training materials, chemical data sheets (SDS), workplace signage, and educational resources to teach hazard communication standards. It matches user intent for understanding chemical risk levels, complying with OSHA/NFPA regulations, or designing safety protocols.
