Portable Extinguishers Fire extinguishers should be provided in areas that contain, or could present a fire exposure hazard to, safety-related equipment in accordance with guidelines of NFPA 10 (Reference 6) , 236 "Portable Fire Extinguishers, Installation, Maintenance and Use.". Dry chemical extinguishers 237 should be installed with due consideration given to possible adverse effects on safety-related equipment installed in the area. 9.5.1-53 DRAFT Rev. 4 - April 1996 7. Guidelines for Specific Plant Areas a. Primary and Secondary Containment (1) Normal Operation - Fire protection requirements for the primary and secondary containment areas should be provided for hazards identified by the fire hazards analysis. Examples of such hazards include lubricating oil or hydraulic fluid system for the primary coolant pumps, cable tray arrangements and cable penetrations, and charcoal filters. Because of the general inaccessibility of primary containment during normal plant operation, protection should be provided by automatic fixed systems. The effects of postulated fires within the primary containment should be evaluated to ensure that the integrity of the primary coolant system and the containment is not jeopardized assuming no action is taken to fight the fire. (a) Operation of the fire protection systems should not compromise the integrity of the containment or other safety-related systems. Fire protection activities in the containment areas should function in conjunction with total containment requirements such as ventilation and control of contaminated liquid and gaseous release. (b) Inside noninerted containment one of the fire protection means stated in Positions C.5.b.1
