atory Guide 1.52. Any filter that includes combustible materials and is a potential exposure fire hazard that may affect safety-related components should be protected as determined by the fire hazards analysis. (5) The fresh air supply intakes to areas containing safety-related equipment or systems should be located remote from the exhaust air outlets and smoke vents of other fire areas DRAFT Rev. 4 - April 1996 9.5.1-46 to minimize the possibility of contaminating the intake air with the products of combustion. (6) Stairwells should be designed to minimize smoke infiltration during a fire. (7) Where total flooding gas extinguishing systems are used, area intake and exhaust ventilation dampers should be controlled in accordance with NFPA 12 (Reference 10) , 181 "Carbon Dioxide Systems," and NFPA 12A (Reference 11) , "Halon 1301 182 183 Systems," to maintain the necessary gas concentration. 184 g. Lighting and Communication Lighting and two-way voice communication are vital to safe shutdown and emergency response in the event of fire. Suitable fixed and portable emergency lighting and communication devices should be provided as follows: (1) Fixed self-contained lighting consisting of fluorescent or sealed-beam units with individual 8-hour minimum battery power supplies should be provided in areas that must be manned needed for operation of safe shutdown equipment and for access and egress routes thereto to and from all fire areas. Safe shutdown areas include those required to 185 be manned if the control room must be evacuated. The level of illumination provided by emergency lighting in access routes to and in areas where shutdown functions must be performed is a level that is sufficient to enable an operator to reach that area and perform the shutdown functions. At the remote shutdown panels the illumination levels should be sufficient for control panel operators.186 (2) Suitable sealed-beam battery-powered portable hand lights should be provided for emergency use
