On the NFPA hazard diamond, which color denotes health hazards?

• A. Blue
• B. Red
• C. Yellow
• D. White

Answer: (A)

In the NFPA 704 hazard diamond, each colored section conveys a different type of hazard. The blue portion specifically indicates health hazards, showing how exposure to the substance could affect your body through inhalation, skin contact, ingestion, or absorption. The numbers inside the sections (0–4) express the severity of the hazard, with higher numbers signaling greater danger. The other colors handle flammability (red), reactivity or instability (yellow), and any special hazards (white). So health hazards are designated by the blue color.
