CBRN Safety 103
CBRN Safety 103 : Chapter II - Domestic CBRN CM (5) Unique Planning Considerations in the Domestic Operational Environment: (E) Control Zones: (1) Hot Zone: The hot zone is an area immediately surrounding a hazardous material incident which extends far enough to prevent adverse effects from released contamination to personnel outside the zone. The level of risk and thus the included area is determined by the incident commander, accounting for characteristics of the hazards. The hot zone can also be referred to as the exclusion zone, red zone, or restricted zone and is the primary area of contamination. The hot zone is the area that the incident commander judges to be the most affected by the incident. This includes any area to which the contaminant has spread or is likely to spread. Primary contamination can occur when individuals enter this zone. Usually, no decontamination or patient care except evacuation is carried out in this zone. Access is only permitted to personnel who are properly trained and protected. The incident commander sets the perimeters of this zone after giving consideration to the type of agent, the volume released, the means of dissemination, the prevailing meteorological conditions, and the potential of local topographic characteristics to channel agent dispersal. Priorities within the hot zone may include conducting search and rescue, performing hazard mitigation, and identifying CBRN hazards or other physical obstacles to the entry point
