l radiological hazard. Deactivation. Shutting down or otherwise idling plant systems and components to prevent their operation, particularly in preparation for abandonment or removal. Decommissioning. Safely removing a facility or site from service and reducing residual radioactivity to a level that permits releasing the property for unrestricted use and terminating the license or releasing the property under restricted conditions and terminating the license. Dismantlement. Physically disassembling and removing plant structures, systems, and components. Emergency responders. Organizations and individuals who respond to plant emergency events (including licensee emergency management and response staff, security personnel, and fire brigades) and offsite responders (including law enforcement officials, medical personnel, and fire departments). Fire apparatus. A vehicle specifically designed to respond to fire events and provided with firefighting tools, equipment, and fire suppression capability. Fire area. A part of a structure that is separated from other areas by space, fire barriers, walls, floors, ceilings, or other means to contain fire within that area. Fire barrier. Construction components (e.g., walls, floors, and ceilings, and their supports, such as beams, joists, and columns; penetration seals; fire doors; and fire dampers) that prevent the spread of heat and fire, restrict the movement of smoke, and are rated by approving laboratories in hours of fire resistance. Fire brigade. A team of onsite plant personnel who have been specifically assigned the responsibility for firefighting and who are adequately equipped for and trained in fighting fires. Fire exposure hazard. A fire hazard that is external to a structure, system, or component in or adjacent to the same area. The exposure to fire effects (e.g., smoke, heat, ignition) may affect the capabilities of adjacent structures, systems, and components to prevent or mitigate the release of radioactive
