Which of the following is NOT a function of the Warm zone?

The Warm zone plays a crucial role in the overall operations during a hazardous materials incident, serving as a buffer area between the Hot zone, where contamination is present, and the Cold zone, which is free from contamination and designated for command and support operations.

In this zone, decontamination procedures are conducted to mitigate the impact of any hazardous materials on personnel and equipment. It is also where contamination assessment occurs to determine the condition and potential hazards of materials being handled. Furthermore, staging for entry into the Hot zone is carried out in the Warm zone, allowing responders to prepare and enter safely.

Medical treatment is typically reserved for the Cold zone, where there is no risk of contamination and medical personnel can provide safe and effective care. Hence, the function that is not associated with the Warm zone is medical treatment area, as this is logically located in the Cold zone to ensure the safety of both patients and medical responders.
