Zones of operation are defined by the relative level of threat. These designations determine where certain actions and specific personnel are allowed to operate. As a result, and for a safer and more efficient response, we identify and label areas at the scene based on our knowledge of the potential threat(s) in each of those areas. We do this by assigning identifiers: the hot zone, the areas of highest risk; the warm zone, an area of intermediate risk; and the cold zone, areas of least risk with regard to the incident.

This presentation was created using content from NCBRT’s PER-340, Active Threat Integrated Response Course.
