Which statement is true about the NFPA diamond and HMIS signs?

The NFPA (National Fire Protection Association) diamond and HMIS (Hazardous Materials Identification System) signs are critical tools used to communicate hazards associated with materials and chemicals safely. The correct choice states that red is for the fire hazard and blue is for the health hazard.

In the NFPA diamond, the colors represent different aspects of hazard: blue signifies the health hazard, red indicates flammability or fire hazard, yellow represents reactivity, and white may denote specific notifications or special hazards.

Similarly, in the HMIS system, color coding is used to communicate the level of hazard; blue also indicates health hazards while red indicates fire hazards. Understanding these color codes assists workers in quickly identifying potential dangers associated with hazardous materials, allowing them to take the necessary precautions for safe handling and use.

By correctly matching the colors to their respective hazards, individuals can better ensure safety in environments where these materials are present. This awareness is critical in preventing accidents and ensuring workplace safety.
