Which zone is used for decontamination operations and is adjacent to the hot zone?

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

Answer: (D)

Decontamination operations happen in a transitional area between the contaminated zone and the clean area. The zone immediately adjacent to the hot zone is the warm zone. It serves as the decontamination corridor where responders and equipment are decontaminated before they move further away from the hazard into the cold zone, helping prevent the spread of contamination. The cold zone lies beyond this area and is kept free of contamination for support and operations, while the hot zone remains the area with the highest level of hazard. The warm zone is specifically designed for decon activities, which is why it’s the correct choice.
