Chapter 19, “Combustible Waste and Refuse,” and Chapter 63, “Compressed Gases and Cryogenic Fluids,” of NFPA 1 and Chapter 5, “Processes and Hazards,” of NFPA 241, “Standard for Safeguarding Construction, Alteration, and Demolition Operations” (Ref. 26), provide information and guidance on the control of combustible materials. NFPA 30, “Flammable and Combustible Liquids Code” (Ref. 27), and NFPA 55, “Compressed Gases and Cryogenic Fluids Code” (Ref. 28), provide information and guidance on the handling, storage, and use of flammable and combustible liquids and gases. 3.4.1 Transient Combustibles Transient fire hazards associated with decommissioning activities should be minimized to the extent possible, and the hazards should be removed promptly upon completion of the activities. In particular, the following practices should be followed: a. The quantity of transient combustible materials should not exceed actual needs and should be separated from ignition sources. Accumulation and storage of combustible wastes should be minimized. b. Wood should not be used for permanent applications in plant areas with a potential for a radiological release. The use of wood for temporary purposes should be minimized, and if used, the wood should be listed as pressure impregnated fire-retardant lumber. c. The use of plastic sheeting should be minimized, and if used, the plastic sheeting should be fire retardant. NFPA 701, “Standard Methods of Fire Tests for Flame Propagation of Textiles and Films” (Ref. 29), provides additional guidance. d. Combustible waste materials that are radioactively contaminated or that present a fire risk to radioactive material should be handled, packaged,
