What color zone is designated as the hot zone in incident management?

In incident management, the hot zone is designated by the color red. This classification is integral to maintaining safety and ensuring that emergency responders can quickly identify areas that present the greatest risk of exposure to hazards. The hot zone represents the area immediately surrounding the incident scene where the potential for danger is highest, whether from fire, toxic substances, or other threats.

The use of the color red for the hot zone enables a universal understanding among responders and provides clear visual cues for the limits of safe operation. When navigating incidents, it is critical that responders understand which areas require full personal protective equipment (PPE) and are restricted to only those personnel who have been adequately trained and equipped to operate in such high-risk environments. This clear designation helps to minimize confusion and enhances situational awareness during operations.
