issioning 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. Standpipe and hose systems should be maintained to provide manual fire suppression capabilities. Standpipe and hose systems should be maintained in areas of the plant that are above or below grade, that require long hose lays from the nearest hydrant, or that are required to maintain the confinement of airborne radioactive materials. Refer to NFPA 14, “Standard for the Installation of Standpipe and Hose Systems” (Ref. 47). b. Manually operated fire suppression systems may be provided to supplement automatic fire suppression systems or in areas where automatic fire suppression systems are not installed and are not needed to rapidly control a fire. The need for manually operated fire suppression systems should be based on consideration of the hazards present; the potential that a fire in a given area could result in release of radioactive materials; the ability to effectively contain, fight, and control the fire using manual suppression; and the ability of personnel to safely evacuate the area. c. Outside hydrants and hose houses should be maintained to support manual fire suppression of internal fires and to protect against the threat of external exposure fires to those plant areas that contain radioactive materials or SSCs necessary for the prevention or mitigation of radioactive material releases. Refer to NFPA 24 for additional information and guidance. 4.3.4 Onsite Fire Brigade and Offsite Fire Emergency Response An onsite fire brigade or offsite emergency services, or both, should provide manual firefighting capability. A fire emergency plan should be developed describing the response to fire alarms and the responsibilities assigned to emergency response personnel (see Regulatory Positions C.3.1, C.3.2, C.3.3, and C.5.2). Refer to NFPA 600, NFPA 801, and NFPA
