Which hazmat zone is the clean area for command, staging, and public safety?

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

Answer: (B)

Hazmat incidents are split into zones by contamination levels, so the clean area used for command, staging, and public safety is the cold zone. Keeping this zone free of contamination lets the incident command post run smoothly, and resources and personnel can be managed safely without specialized protective gear. It also provides a staging area where equipment and responders can assemble before entering any contaminated areas, and a place for public safety operations to occur without exposure risk. In contrast, the hot zone is where the hazard is present and access is restricted to trained personnel with appropriate protection. The warm zone surrounds the hot zone and includes decontamination and support functions, acting as a transition between contaminated and clean. The decon zone is specifically for decontamination activities, typically located within the warm zone.
