In a hazmat incident, which zone is the clean area for command, staging, medical, and administrative activities?

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

Answer: (D)

In hazmat incidents, zones separate areas by contamination levels to protect people and operations. The clean area used for command, staging, medical, and administrative activities is the cold zone. It stays outside the hazardous plume, allowing personnel to operate with minimal risk and without heavy PPE, while incident command, resource staging, medical treatment, and admin tasks run from this secure, decontaminated space. The decontamination process occurs at the boundary between the warm and cold zones, and the hot zone is the area with active contamination where only fully protected personnel work.
