aining a fire that consumes all combustibles present. Examples of such combustible materials that may not be separable from the remainder of its system are: (a) Emergency diesel generator fuel oil day tanks. (b) Turbine-generator oil and hydraulic control fluid systems. (c) Reactor coolant pump lube oil system. 9.5.1-43 DRAFT Rev. 4 - April 1996 (2) Bulk gas storage (either compressed or cryogenic), should not be permitted inside structures housing safety-related equipment. Storage of flammable gas such as hydrogen should be located outdoors or in separate detached buildings so that a fire or explosion will not adversely affect any safety-related systems or equipment. (Refer to NFPA 50A [Reference 22] , "Gaseous Hydrogen Systems." ) 164 165 Care should be taken to locate high pressure gas storage containers with the long axis parallel to building walls. This will minimize the possibility of wall penetration in the event of a container failure. Use of compressed gases (especially flammable and fuel gases) inside buildings should be controlled. (Refer to NFPA 6 , "Industrial Fire Loss 166 Prevention." ) 167 Additional guidelines and criteria for the design, installation, and operation of flammable cryogenic and compressed gas systems are provided in Generic Letter 93-06 (Reference 49), EPRI report EPRI NP-5283-SR-A (Reference 57) as approved by the NRC in Reference 52, and the NRC SER for the Dresden Mobile Volume Reduction System (Reference 53).168 (3) The use of plastic materials should be minimized. In particular, halogenated plastics such as polyvinyl chloride (PVC) and neoprene should be used only when substitute noncombustible materials are not available. All plastic materials, including flame and fire retardant materials, will burn with an intensity and BTU production in a range similar to that of ordinary hydrocarbons. When burning, they produce heavy smoke that obscures visibility and can plug air filters, especially charcoal and HEPA. The halogenated
