tion for fighting the fire, as well as all access and egress routes involving locked doors and the appropriate precautions and methods for access specified; (5) plant systems that should be managed to reduce the damage potential during a local fire and the location of local and remote controls for such management (e.g., any hydraulic or electrical systems in the area or zone covered by the specific firefighting procedure that could increase the hazards in the area because of overpressurization or electrical hazards); (6) vital heat-sensitive system components that need to be kept cool while fighting a local fire (in particular, hazardous combustibles that need cooling); (7) organization of firefighting brigades and the assignment of special duties specific to the affected fire area; DG-1359, Page 55 (8) potential radiological and toxic hazards in fire areas or zones; (9) ventilation system operation that ensures desired plant air distribution when the ventilation flow is modified for fire containment or smoke clearing operation; (10) operations requiring control room and shift engineer coordination or authorization; (11) instructions for plant operators and general plant personnel during fires; and (12) communications among the fire brigade leader, fire brigade, offsite mutual aid responders, control room, and licensee’s emergency response organization. Appropriate firefighting procedures should identify the techniques and equipment for the use of water in fighting electrical cable fires in nuclear plants, particularly in areas containing a high concentration of electric cables with plastic insulation. NFPA 1620, “Standard for Pre-Incident Planning” (Ref. 91), provides additional guidance on pre-fire planning. 3.5.1.4 Performance Assessment and Drill Criteria Fire brigade drills should be performed in the plant so that the fire brigade can practice as a team. Drills should be performed quarterly for each shift’s fire brigade. Each fire brigade member should
