Which diamond color represents health hazards?

The diamond color that represents health hazards is blue. This color coding system, particularly used in the context of the National Fire Protection Association (NFPA) labeling, identifies specific hazards associated with materials and chemicals.

In this system, blue indicates health hazards such as toxicity, carcinogenicity, or other health-related risks. When a material is marked with a blue diamond, it indicates the severity of the health hazard that it poses to individuals who may come into contact with it. The scale ranges from 0 (no hazard) to 4 (extreme hazard), providing emergency responders and workers with crucial information about the dangers of handling the materials.

Other colors in the NFPA system have different meanings; for example, red signifies flammability, yellow denotes reactivity or instability, and white is often used to indicate specific hazards or instructions. This helps ensure a clear understanding of the risks associated with hazardous materials in various environments.
