In hazmat response, the warm zone is described as:

• A. The hot zone where contamination is present
• B. An uncontaminated environment where contaminated victims, responders, and equipment are brought
• C. The area outside the incident that is unaffected
• D. The command post

Answer: (B)

Hazmat response uses zones to prevent spread of contamination, with the warm zone serving as the transfer and decontamination area between the contaminated hot zone and the clean cold zone. The purpose of this zone is to receive contaminated victims, responders, and equipment from the hot zone and perform decontamination before they move into the cold zone. It is a controlled, transitional space where PPE protocols are followed and decontamination procedures take place, reducing the level of contamination before anyone or anything enters the uncontaminated area. The hot zone contains the source of contamination; the cold zone is the area outside the incident that is unaffected, and the command post is typically located in the cold zone or its boundary.
