ain) must also be designed to these requirements. The remainder of the water systems must be designed to the appropriate fire protection standards such as NFPA 13 and NFPA 15. During normal operation, the seismically designed and non-seismically designed systems must be separated by normally closed valves and a check valve, so that a break in the non-seismically analyzed portion of the system cannot impair the operation of the seismically designed portion of the system.221 (5) The proper type of hose nozzle to be supplied to each area should be based on the fire hazard analysis. The usual combination spray/straight-stream nozzle should not be used in areas where the straight stream can cause unacceptable mechanical damage. Fixed fog nozzles should be provided at locations where high-voltage shock hazards exist. All hose nozzles should have shutoff capability. (Guidance on safe distances for water application to live electrical equipment may be found in the "NFPA Fire Protection Handbook" [Reference 62] .) 222 (6) Fire hose should be hydrostatically tested in accordance with the recommendations of NFPA 1962 (Reference 32) , "Fire Hose - Care, Use, Maintenance.". Hose stored in 223 224 outside hose houses should be tested annually. Interior standpipe hose should be tested every 3 years. (7) Certain fires, such as those involving flammable liquids, respond well to foam suppression. Consideration should be given to use of mechanical low-expansion foam systems, high-expansion foam generators, or aqueous film-forming foam (AFFF) systems, including the AFFF deluge system. These systems should comply with the requirements of NFPA 11 (Reference 7) , NFPA 11A (Reference 8) , NFPA 11B 225 226 227 (Reference 9) , and NFPA 16 (Reference 16) , as applicable. 228 229 d. Halon Suppression Systems Halon fire extinguishing systems should comply with the requirements of NFPA 12A and NFPA 12B (Reference 12) , "Halogenated Fire Extinguishing Agent Systems - Halon 1301 and Halon 230
