and operation of automatic fire protection systems should be based on NFPA 11, “Standard for Low-, Medium-, and High-Expansion Foam” (Ref. 39); NFPA 12, “Standard on Carbon Dioxide Extinguishing Systems” (Ref. 40); NFPA 12A, “Standard on Halon 1301 Fire Extinguishing Systems” (Ref. 41); NFPA 13; NFPA 15, “Standard for Water Spray Fixed Systems for Fire Protection” (Ref. 42); NFPA 16, “Standard for the Installation of Foam-Water Sprinkler, and Foam-Water Spray Systems” (Ref. 43); NFPA 17, “Standard for Dry Chemical DG-1370, Page 19 Extinguishing Systems” (Ref. 44); NFPA 17A, “Standard for Wet Chemical Extinguishing Systems” (Ref. 45); and NFPA 75, “Standard for the Fire Protection of Information Technology Equipment” (Ref. 46). The need for automatic fire protection systems in plant areas during decommissioning activities may change, depending on the type of operations being performed in an area, the addition or removal of combustible materials, or the removal of radioactive materials and contamination. Plant areas should be reviewed for changing conditions that could affect the need for automatic fire suppression systems. 4.3.3 Manual Fire Suppression Systems Manual fire suppression systems should be provided in the plant to supplement automatic fire protection systems and to provide suppression coverage to areas not protected by automatic systems. Decommissioning activities may change the plant configuration and fire hazards, may require the construction of temporary enclosures or structures, and may necessitate the abandonment or removal of automatic systems as facilities are dismantled or modified and radiological hazards are removed. Adequate manual fire suppression capability must be provided or maintained based on the decommissioning fire hazards analysis to ensure protection against fire-induced radioactive material releases. The following considerations are important in evaluating the manual fire protection systems: a.
