matic and manual water-based fire suppression systems DG-1370, Page 23 should meet Section 3.9 of NFPA 805, and the design of gaseous fire suppression systems should meet Section 3.10 of NFPA 805. 6.5 Portable Fire Extinguishers As described in Section 5.3.3 of NFPA 805, portable fire extinguishers are should remain in plant areas described in the decommissioning plan until combustibles and ignition sources have been removed. Additional extinguishers should be installed commensurate with the changes in fire hazards, plant conditions, and necessary manual firefighting activities as discussed in Section 3.4.4 of NFPA 805. The licensee should maintain the fire extinguishers as described in Section 3.7 of NFPA 805. 6.6 Standpipes and Hose Stations As described in Section 5.3.4 of NFPA 805, existing hose and standpipe systems should remain functional to support the decommissioning plan. Regulatory Position C.4.3.3 of this guide describes other considerations for maintaining standpipe and hose stations. The licensee should maintain the hose station and standpipe systems as described in Section 3.6 of NFPA 805. 6.7 Onsite and Offsite Firefighting Response NFPA 805 Chapter 5 requires an onsite industrial fire brigade consistent with Section 3.4 The licensee should continue to maintain pre-fire plans and onsite industrial fire brigade equipment consistent with Sections 3.4.2 and 3.4.4 of NFPA 805. The licensee should revise the pre-fire plans when the occupancy or fire risk for the area has substantially changed because of decommissioning conditions and activities. The licensee should continue to maintain the industrial fire brigade drills and training, including the interface with offsite fire departments, as described in Sections 3.4.3 and 3.4.5. The level of training, type of drills, and level of offsite fire department support should continue commensurate with the hazards during the decommissioning activities.
