Position number four corresponds to which hazard?

Position number four corresponds to which hazard?

• A. Special information (white)
• B. Health (blue)
• C. Reactivity (yellow)
• D. Flammability (red)

Answer: (A)

Think about the NFPA 704 hazard diamond, which uses three colored sections to rate health, flammability, and reactivity, plus a white section for anything special. The colored quadrants (blue for health, red for flammability, yellow for reactivity) carry the risk ratings. The white quadrant is separate and is where you note special information that can change how you handle or respond to a spill or incident—things like oxidizing nature, water reactivity, corrosivity, or other unique hazards. So position four corresponds to special information (white). This is why it’s the best answer: it identifies those extra, non-numeric hazards that you must consider in addition to the standard health, flammability, and reactivity ratings. The other colors cover the main hazard categories, not the special notes.
