Understanding NFPA 704 Hazard Diamonds for Chemical Safety #3731019 (License: Personal Use)

The image displays two standard NFPA 704 hazard identification diamonds used in industrial and laboratory safety. Each diamond is divided into four colored quadrants-red for flammability, blue for health hazard, yellow for reactivity, and white for special hazards-with letters indicating severity levels (e.g., D = slight, M = moderate, S = stable/special). These visual tools help emergency responders and workers rapidly assess risks during handling, storage, or incidents.

This image is commonly used on occupational safety training pages, OSHA compliance guides, chemical safety datasheets, and emergency response protocols. It supports user intent to understand hazard labeling systems for workplace safety, regulatory compliance, or academic study of hazardous materials.
