What zone is characterized by hot (red) contamination?

The hot zone is characterized by red contamination, indicating the area that is immediately dangerous and where hazardous materials are present. This zone is located closest to the source of contamination and is where the most severe risk exists. Personnel entering this area need to wear appropriate personal protective equipment (PPE) to safeguard themselves from exposure to harmful substances. The use of the color red to signify the hot zone is a standard practice in emergency response and hazardous material management, signaling the highest level of danger.

In contrast, the clean zone is an area that is completely free of contamination, allowing for safe patient care and treatment. The cold zone is a safe area where decontamination can occur, and it is typically used for support and command functions. The warm zone acts as a transition area between the hot and cold zones, where personnel can take precautions before entering or leaving the contaminated area. Each of these zones serves a distinct purpose in the overall safety and effectiveness of emergency operations, highlighting the importance of understanding their characteristics and functions.
