(a) Specifications and Permits. Plans showing the location, size and connections of the yard system shall be submitted to the Bureau of Fire Prevention and Investigation for approval. The plans shall be to scale and include the details necessary to indicate clearly all apparatus and its arrangements. The plans shall be accompanied by specifications covering the character of the material and features relating to the installation in detail.
(b) Hydrant System. Whenever the ground area of the premises of an industrial plant, tank farm, storage area, shopping center, apartment building or other occupancy involving the use of large ground area exceeds 10,000 square feet and such premises are so located or arranged that efficient fire fighting cannot be carried on from existing public hydrants, yard hydrants shall be provided. Yard hydrants may be required if the distance from any portion of a building to a public hydrant is more than 300 feet in the direction of travel as determined by the Bureau of Fire Prevention.
(c) Number and Location Required. When yard hydrants are required, such hydrants shall be located not more than ten feet from a driveway or parking area and spaced not more than 300 feet apart. For average condition conditions, hydrants should be placed approximately fifty feet from the buildings or structures to be protected. Where it is impractical to place them at this distance, they may be placed in other locations provided they are not more than 150 feet from the buildings or structures to be protected and provided they are not located where the chance of injury by falling walls, smoke or heat is great.
(d) Types of Hydrants and Fittings. All hydrants shall be a minimum of eight inches in size, with triple connections, and shall have an approved underground shut-off valve located not more than ten feet from the hydrant. All hydrants shall comply with Berea's standards.
When deemed necessary by the Bureau of Fire Prevention and Investigation, or when required by this Fire Prevention Code, suitable siamese connections and check-valves shall be installed in the yard system main at the junction with the public main. Not less than eight-inch diameter pipe shall be installed underground in yard systems for mains or branches. In large installations, a loop system may be required in view of its larger carrying capacity. The size of the pipe supplying the yard system shall be approved by the Bureau of Fire Prevention and Investigation, with due consideration being given to the construction and occupancy of the yard system and to the volume and pressure of available water. Yard hydrants and post indicator valves shall be maintained and painted as required by the Bureau of Fire Prevention and Investigation.
