Filling Pipe. The end of the fill pipe for all flammable liquids storage tanks shall be carried to a location outside of all buildings and shall be more than five feet from any door or window or any other opening. The fill pipe shall be closed by a screw cap or fill cap and Class I flammable liquids shall be provided with locks and kept locked except during the filling operation. In buildings of Type IA construction where the tank for diesel oil is above the first floor the fill shall be in the same room as the tank.
Standard Filling Hose. All hose used for the transferring of flammable liquids shall be of the metal lined type, or of the type embodying wire wound within the fabric of the hose, and thoroughly bonded to the coupling connection at each end of the hose. Deliveries of flammable liquids of Class I and Class II shall be made directly to the storage tank through the fill pipe by means of a hose or pipe connected to the fill pipe in the barrel, container, tank, wagon or tank car from which such liquid is being drawn.
Pumps Required. Flammable liquids shall be drawn from tanks by Underwriters' Laboratories, Inc. listed pumps, which shall be equipped with controlling apparatus, and the piping system shall be so arranged as to control the quantity of discharge and to prevent leakage or discharge inside of the building by any derangement of the system. When located inside a building, the pump for Class I liquids, except fuel oil used for heating purposes, shall be located at grade level in a well ventilated place. Class II and III flammable liquid pumps may be below the ground floor but not installed in any pit or manhole and the dispensing of such liquid shall be on or above the ground floor in a well ventilated place.
Cross-Connections. No cross-connection of Class I flammable liquids shall be permitted with Classes II and III and there shall be separate pipelines and pumps maintained for Class I as distinguished from Classes II and III. However, this requirement shall not apply to occupancies containing flammable liquid processing operations wherein all pumps and electrical equipment are of the type approved for use in hazardous locations, as required by the electrical regulations of this Code.
