All required standpipe installations shall be made in conformity with plans therefor which have been approved by the Fire Chief. Plans submitted for approval shall clearly indicate, in diagrammatic fashion, all component parts of the proposed system or systems, and the proposed location of all component parts.
(Ord. No. 991-49. Passed 6-27-49, eff. 6-27-49)
As used in this Fire Prevention Code:
(a) “Standpipe” means a pipe exclusively for firefighting purposes ending vertically throughout all stories of a building, including basement and cellars having one (1) or more inlets close to the grade level and on or adjacent to those exterior walls of a building which face a street or alley, and having outlets on every story, basement and cellar.
(b) “Dry standpipe” means a standpipe without fixed connection to a source of water and maintained without water in the piping.
(c) “Wet standpipe” means a standpipe connected to an open or automatically provided source of water with water available at all outlets at all times.
(d) “First-aid hose” means hose permanently attached to a standpipe outlet and provided primarily for use in firefighting by the occupants of the building. First-aid hose shall not exceed one and one-half (1-1/2) inches in diameter unless larger hose is specifically approved or directed by the Division of Fire.
(e) “Siamese” means a device on the exterior wall of a building, or in another approved location, equipped with inlets for attachment of Fire Division hose.
(Ord. No. 991-49. Passed 6-27-49, eff. 6-27-49)
(a) Pipe for standpipe systems shall be wrought iron or steel, except that underground pipe may be of cast iron and except that other materials may be used when approved by the Board of Building Standards and Building Appeals. All piping of standpipe systems which may be subjected to pressure supplied by the Fire Division connections shall be designed for a working pressure of not less than one hundred (100) psi in excess of the static head of water due to the height of the standpipe.
(b) Every device, valve, fitting or hose used in connection with any required standpipe system shall be of a type approved by the Board. Devices, valves, fittings and hose of type tested and approved by the Underwriters’ Laboratories, Inc., or tested and approved by another recognized testing laboratory which possesses adequate equipment, experience and competency in this field, may be approved by the Board without additional tests.
(Ord. No. 991-49. Passed 6-27-49, eff. 6-27-49)
(a) All standpipes shall be so located that they are protected against corrosion and against physical and fire damage.
(b) All wet standpipes shall be so installed that they are protected against damage due to frost action.
(c) Standpipe outlets for use of the Division of Fire shall be within stairway enclosures. However, in buildings heretofore erected in which the stairways are not enclosed, such standpipe outlets shall be located as near the stairway as possible, or shall be outside or immediately inside the exterior walls within one (1) foot of an exterior stairway or fire escape as directed or approved by the Division.
(d) Standpipes and standpipe outlets in connection with assembly occupancy shall be located as specified by the Ohio Building Code.
(e) In Class B multiple dwellings, and in buildings or parts of buildings of mercantile occupancy, institutional occupancy or educational occupancy, first- aid hose, and the outlets therefor, shall be located in a public hallway, corridor or floor space, and hose shall be either within a cabinet, or on open racks, in an approved location where egress will not be obstructed thereby. First-aid hose in buildings of other occupancy classifications may be directly connected to the standpipe within a stair enclosure, or may be within an adjoining public hallway, corridor or floor space. Cabinet doors shall be plainly marked “Fire Hose” in letters not less than four (4) inches high.
(f) The location of all standpipes and standpipe outlets shall be subject to the approval of the Division.
(Ord. No. 991-49. Passed 6-27-49, eff. 6-27-49)
(a) Standpipe locations in theaters and assembly halls regulated by the Ohio Building Code shall be as specified in that Code.
(b) Other required standpipes shall be in such number and so located that all parts of all floor areas are within thirty (30) feet of a nozzle attached to one hundred (100) feet of Fire Division hose connected to a standpipe outlet provided for use of the Division and can be reached by a stream from such nozzle.
(c) Where first-aid hose is required by this Fire Prevention Code, it shall be provided and so located that all parts of every floor area are within twenty (20) feet of a nozzle attached to seventy-five (75) feet of hose connected to the valve at a first-aid hose station and can be reached by a stream from such nozzle.
(Ord. No. 991-49. Passed 6-27-49, eff. 6-27-49)
(a) When standpipes are required by this Fire Prevention Code, buildings seventy-five (75) feet or less in height above grade level shall have standpipes not less than four (4) inches in diameter.
(b) Buildings exceeding seventy-five (75) feet in height above grade level shall have standpipes not less than six (6) inches in diameter.
(c) Standpipes intended only for first-aid streams and provided in addition to and supplementary to required four (4) inch or six (6) inch standpipes shall be not less than the following:
(1) Two (2) inch for buildings up to and not exceeding four (4) stories or fifty (50) feet in height;
(2) Two and one-half (2-1/2) inch for buildings in excess of four (4) stories in height.
(d) Standpipes in theaters and assembly halls regulated by the Ohio Building Code shall be not less than the size specified in that Code.
(Ord. No. 991-49. Passed 6-27-49, eff. 6-27-49)
(a) When more than one (1) standpipe is required in a building the standpipes shall be connected at their bases by pipe of a size equal to or greater than that of the larger standpipe to permit water from any source to supply all standpipes. Where only one (1) standpipe is installed, the supply connections thereto shall not be smaller than the standpipe. Where standpipes are supplied by gravity or pressure tanks located above the standpipe system, the supply pipe therefrom to the standpipe system shall not be smaller in size than the larger standpipe.
(b) Where the water supply is furnished by a gravity tank or a pressure tank located in the building at or above the topmost outlet, a check valve shall be provided below the tank and a stop valve between the check valve and the tank.
(c) Sufficient stop valves or check valves shall be provided to permit cutting off any standpipe riser without interrupting the supply to other risers from the same source of supply. Stop valves which are located above the ground floor and which must be closed to permit continued use of one (1) standpipe in case of failure of another, shall be arranged and equipped to permit operation of such stop valves from the ground floor level, from the pump room or from other accessible locations approved by the Division of Fire. Where necessary to reach manually operated stop valves placed more than six (6) feet above a floor level, fixed incombustible ladders shall be provided.
(d) Each water service connection which directly and independently supplies a stand-pipe system or fire pipe shall be equipped outside of the building in an approved location with a control valve in a flush sidewalk or lawn valve box of an approved type, or with a post indicator valve, clearly marked “Standpipe Supply Control.” Each such water service connection shall be installed in conformity with ordinances governing water service connections and the rules and regulations of the Division of Water and Heat.
