Which is not a recognized hazmat zone?

• A. Cold zone
• B. Warm zone
• C. Hot zone
• D. Green zone

Answer: (D)

Hazmat response relies on three established zones to keep personnel safe and to manage contamination: the area where the hazard is present (hot zone), the decontamination area (warm zone) where protective gear is removed and decon occurs, and the clean area (cold zone) where command, support, and noncontaminated operations take place. The term green zone isn’t part of this standard zoning scheme; it isn’t an officially recognized HazMat zone. While some agencies might use informal labels to describe safe or non-contaminated spaces, the recognized framework for zone separation is hot, warm, and cold, which is why the green label would be considered not part of the official zoning.
