(a) Specifications and Permits.
(1) Plans showing the location, size and connections of the yard system shall be furnished by the Fire Chief. The plans shall be to scale and shall include the details necessary to indicate clearly all apparatus and its arrangements.
(2) The plans shall be accompanied by specifications covering the character of the material and features relating to the installation in detail.
(3) Upon the approval of the Fire Chief, a permit for the installation will be issued.
(b) Hydrant.
(1) When required. Whenever the ground area of the premises of an industrial plant, tank farm, lumber yard, storage area, shopping center or other occupancy involving the use of large ground area exceeds 15,000 square feet, and whenever the area of a lumber shed or sheds on any premises exceeds 5,000 square feet aggregate area, and such premises are so located or arranged that efficient firefighting cannot be carried on from existing public hydrants, the Fire Chief may require the installation of yard hydrants by the owner of the premises in conformity with the provisions of this section.
(2) Number required.
A. Premises of Large Ground Area. One yard hydrant shall be provided for each 20,000 square feet of ground area and such hydrants shall be spaced not more than 300 feet apart.
B. Lumber Yards. Yard hydrants in lumber yards shall be spaced not more than 250 feet apart and shall be in such number and so located that streams therefrom, when used in first aid or Fire Division firefighting, shall reach all areas on the premises, including those within lumber sheds.
C. Every required yard hydrant within a lumber yard shall be equipped with attached hose kept within a hose house.
(c) Type Hydrants and Fittings.
(1) All hydrants, hose, hose connections and nozzles shall conform to the Fire Division standard. These hydrants shall be supplied by a main of not less than six inches. For average conditions hydrants should be placed about fifty feet from the buildings protected. Where it is impossible to place them at this distance, they may be put nearer, provided they are set in locations where the chance of injury by falling walls is small, and from which men are not likely to be driven by smoke or heat.
(2) No smaller than six-inch pipe shall be installed underground in yard systems for mains or hydrant branches. In moderately large plants a loop system is advised on account of its larger carrying capacity. The size of the pipe supplying the yard system shall be determined by the Fire Chief, due consideration being given to the construction and occupancy to volume and pressure of water.
(d) Hose Houses. When deemed necessary by the Fire Chief or required by this chapter, hose houses or cabinets containing an adequate supply of rubber lined cotton hose, two and one-half inch in size the yard hydrant or hydrants and arranged or laid within a hose house shall be ready for use at any time. Nozzle size shall not be larger than one and one-eighth inch. Hose houses shall be painted red with words "Fire Hose", six inches high in white letters on the door or doors.
(e) Water Supply.
(1) Where adequate pressure and capacity exist, yard hydrants may be connected to the public water supply. Where the public water supply is deemed inadequate by the Fire Chief, such yard hydrants shall be supplied either from gravity tank of not less than 50,000 gallons capacity elevated so that the bottom of the tank is at least seventy-five feet high above the highest grade level within the area protected or at least twenty-five feet above the highest structure in the area; or from a fire pump or fire pumps with a capacity of not less than 1,000 gallons a minute drawing from a suction tank of not less than 60,000 gallons capacity, or from other approved source which will provide an adequate supply of water for firefighting purposes.
(2) When water supply is taken from a well, stream, lake or other source approved by the Fire Chief, no connection shall be made which may result in a cross connection between the public main and the water drawn from other sources.
(3) Yard hydrants and post indicator valves shall be painted red and their purpose shall be plainly marked upon them.
(f) Monitor Nozzle and First Aid Hose. Whenever the occupancy is of unusual hazard the Fire Chief may require the installation of a monitor nozzle or nozzles with remote control, connected to such yard hydrant system. Where unusual hazards exist and where first aid firefighting equipment is deemed necessary by him, he may also require the installation of one and one-half inch first-aid hose mounted on approved racks and connected to piping not less than two inches in size.
(g) Hydrostatic Test. All new yard piping shall be tested hydrostatically at not less than 200 pounds per square inch pressure for two hours, or at fifty pounds per square inch in excess of the maximum of 150 pounds per square inch.
