What is defined as the area outside the hot zone where PPE is not required?

The cold zone is defined as the area outside the hot zone where personal protective equipment (PPE) is not required. This zone serves as a safe area for personnel who are not directly involved in operations that entail exposure to hazardous conditions, such as toxic gases, extreme temperatures, or other dangers present within the hot zone. The cold zone is crucial for maintaining safety protocols, allowing rescuers and support personnel to regroup, plan, and prepare without the need for extensive protective gear.

By identifying the cold zone, rescue technicians can effectively manage their resources and ensure that everyone involved in the operation is appropriately equipped, considering the specific hazards present in various zones of a rescue operation. The separation of zones based on risk is essential for a fluid and safe approach to confined space rescues.
