The term "cold zone" refers to the safe area known as the clean zone during a hazardous materials incident. In the context of emergency response to hazardous materials, the incident site is typically divided into three zones: the hot zone, warm zone, and cold zone.

The cold zone is the area where no contamination from hazardous materials is expected, and it is safe for emergency responders and civilians. This zone is critical because it serves as a staging area for support services, command centers, and decontamination areas, where personnel and equipment can be assessed and treated if necessary without the risk of exposure to hazardous substances.

Maintaining a clear distinction between these zones is essential for the safety of all involved and to ensure proper management of the incident. The hot zone is where the hazardous materials are actively present, posing a risk to those who enter, while the warm zone serves as a transitional area for decontamination before entering the clean environment of the cold zone. Thus, identifying and correctly using the term "cold zone" underscores the importance of safety protocols in managing hazardous materials incidents.
