lve supplying the sprinkler systems where such headers are part of the seismically analyzed hose standpipe system. When provided, such headers are considered an extension of the yard main system. Each sprinkler and standpipe system should be equipped with OS&Y (outside screw and yoke) gate valve or other approved shutoff valve and waterflow alarm. Safety-related equipment that does not itself require sprinkler water fire protection but is subject to unacceptable damage if wet by sprinkler water discharge should be protected by water shields or baffles. (2) Control and sectionalizing valves in the fire water systems should be electrically supervised or administratively controlled. The electrical supervision signal should indicate in the control room. All valves in the fire protection system should be periodically checked to verify position (see NFPA 26 [Reference 19] , "Supervision of 209 Valves" ). 210 (3) Fixed water extinguishing systems should conform to requirements of appropriate standards such as NFPA 13, "Standard for the Installation of Sprinkler Systems," and 211 NFPA 15, "Standard for Water Spray Fixed Systems.".212 (4) Interior manual hose installation should be able to reach any location that contains, or could present a fire exposure hazard to, safety-related equipment with at least one effective hose stream. To accomplish this, standpipes with hose connections equipped with a maximum of 30 m (100 feet) of 3.8 cm (1-1/2-inch) woven-jacket, lined fire 213 214 hose and suitable nozzles should be provided in all buildings on all floors. Individual standpipes should be at least 10 cm (4 inches) in diameter for multiple hose 215 connections and 6.4 cm (2-1/2 inches) in diameter for single hose connections. These 216 systems should follow the requirements of NFPA 14 (Reference 14) , "Standpipe and 217 Hose Systems," for sizing, spacing, and pipe support requirements. 218 Hose stations should be located as dictated by the fire hazard analysis to facilitate
