In a public health decontamination context, which zone is designated for decontamination activities?

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

Answer: (B)

In a public health decontamination setup, the warm zone is the area for decontamination activities. It sits between the contaminated hot zone and the clean cold zone, acting as the controlled corridor where PPE doffing, personnel and equipment decontamination, and waste containment occur. Keeping decontamination in this buffer zone helps prevent contaminants from spreading into the clean area and allows for proper supervision and management of decon fluids and runoff.

The hot zone is where contamination is present and requires full protective measures, while the cold zone remains clean and ready for safe entry. A training zone isn’t part of the actual decontamination process; it’s used for drills and instruction rather than real-world decontamination operations.
