- tribute the water throughout the area protected and will discharge the water through sprin- klers in sufficient quantity either to extinguish the 'fire entirely or to prevent its spread. The system, usually activated by heat, includes a controlling valve and a device for actu- atilhg an alarm when the system is In operation. The following categories of sprinkler systems are defined in NFPA 13, "Standard for the Installation of Sprinkler Systems": Wet-Pipe System Dry-Pipe System Preaction System Deluge System Combined Dry-Pipe and Preaction System On-Off System Standpipe and Hose Systems - a fixed piping system with hose outlets, hose, and nozzles connected to a reliable water supply to provide effective fire hose streams to specific areas inside the building. Water Spray System - a network of piping similar to a sprinkler system except that it uti- lizes open-head spray nozzles. NFPA 15, "Water Spray Fixed Systems," provides guidance on these systems. 1. 120-4 C. REGULATORY POSITION 1. Overall Requirements of the Fire Protection Program a. Personnel Responsibility for the overall fire protection program should be assigned to a desig- nated person in the upper level of management who has management control over the organizations involved in fire protection activities. This person should retain ultimate responsibility even though formulation and assurance of program implementation is delegated. Such delegation of authority should be to a staff composed of personnel prepared by training and experience in fire protection and personnel prepared by training and experience in nuclear plant safety to provide a balanced approach in directing the fire protection program for the nuclear power plant. The staff should be responsible for: (1) Coordination of fire protection program requirements, including consideration of potential hazards associated with postulated fires, with building layout and systems design. (2) Design and maintenance of fire detection, suppression, and
