Which of the following is true about the Warm Zone?

The Warm Zone is characterized as the area where the transition happens between the Hot Zone and the Cold Zone. It serves a critical function in incident management by facilitating access control to the Hot Zone, which is typically where the most dangerous conditions or hazardous materials are present. In the Warm Zone, personnel are protected from immediate threats while allowing for the movement of emergency responders and equipment to and from the Hot Zone. This area is crucial for managing safety protocols, ensuring that only authorized personnel can gain access to the more hazardous areas while still preparing and coordinating for medical treatment and decontamination as necessary.

The other contexts provided highlight that the Warm Zone is not entirely unsafe for all personnel, it is not necessarily located downwind from the Hot Zone, and while medical treatment can occur in the Cold Zone or in designated areas, the actual treatment of victims typically happens there instead of in the Warm Zone.
