(c) Storage in Bulk of Fuel-oil for Use in connection with Internal-combustion Engines or Oil-burning Equipments.

55. Clauses 35 to 41 inclusive of these regulations shall apply to underground tanks for the storage of fuel-oil, with the following exceptions:—

(a) In cases where it is not practicable to comply with clause 36 hereof the tank may be placed in a cellar or basement floor in a brick or concrete pit constructed in such manner as to ensure that the tank is protected on all sides with not less than 2 ft. of insulating material (concrete, earth, sand, or clay). If the tank is not placed below the level of any piping to which it may be connected, an anti-siphoning device of a type approved by the Chief Inspector, shall be installed in such manner as to prevent siphoning or gravity flow of oil in case of accident to the equipment or piping.

(b) A quantity not exceeding 1,000 gallons of fuel-oil may be stored in an installation coming within the provisions of clause 41 (a) hereof.

56. There may be attached to an underground-tank installation a gravity or service tank from which fuel oil is supplied directly or through a feed-tank to the engine or furnace. The following provisions shall apply to the installation of such service tanks:—

(a) The capacity of the service-tank shall not exceed 60 gallons unless the normal oil-consumption of the installation exceeds 60 gallons in eight hours, when a service-tank of such capacity not exceeding 275 gallons as may be approved by an Inspector may be installed.

(b) The service tank shall be sealed and provided with a vent pipe constructed and installed in accordance with clause 38 of these regulations.

(c) The tank must be provided with an overflow-pipe of larger diameter than the supply-pipe. Such overflow-pipe must have a distinct fall all the way to the storage-tank. No valve shall be placed on the overflow-pipe.

(d) Service tanks shall be filled only by pumping from the storage tank or tanks.

(e) Service tanks shall not be situated within 10 ft., measured horizontally, from any fire or flame. Service tanks shall be substantially and rigidly installed on incombustible supports in such manner as to ensure protection against mechanical injury.

57. All piping connections in the installation shall be run as directly as possible without sags, and be so laid that, where possible, pipes pitch towards the supply-tanks without traps. Provision shall be made for expansion, contraction, jarring, and vibration. Piping, after installation, shall be tested and proven tight at a pressure of 20 lb. to the square inch.

58. Where it is necessary to heat oil in storage or service tanks in order to handle it, the oil shall not be heated to a temperature higher than 40° C. below its flashing - point. Heating shall be done by means of properly installed coils in the tank, using only steam or water. Thermostatic control and thermometer shall be provided for all heating devices.

59. All pumps and burners used in connection with any fuel-oil installation shall be of a type approved by the Chief Inspector, and shall be maintained at all times secure against leaks.

60. Valves shall be provided in readily accessible positions near each burner and also close to the service tank in the pipe-line to burners.

61. Means for remote control of the flow of oil to the burner shall be provided for use in emergency, and a sign indicating its purpose shall be located at the control device:

Provided that a switch in the motor supply-circuit may serve this purpose for an electrically driven equipment, or a quick-closing valve in the oil-supply line, arranged to be operated from a safe location, preferably outside the building, may be used.

62. Furnaces or ranges used with fuel-oil burners shall be designed to give adequate ventilation to prevent accumulation of inflammable vapour.

63. The occupier of the premises where fuel oil is stored for use in a burner shall install an approved fire-extinguisher of the foamite or tetrachloride type in the vicinity of each burner or group of burners, and shall at all times maintain such extinguisher in good working-order.

(d) Storage in Bulk of Petroleum Spirit, Petroleum Oil, and Fuel-oil in Above-ground-tank Depots.

64. No license shall be issued to store petroleum in bulk in any premises adjacent to any harbour from or to which harbour it is proposed to deliver petroleum by means of pipelines, and no local authority shall establish or maintain any such depot in any premises adjacent to any such harbour, unless the situation of the premises and the provisions made or proposed to be made for the public safety and for compliance with these regulations have been approved by a Board consisting of the following persons:—

(a) The Naval Adviser to the Government or a deputy appointed by him;

(b) The Chief Inspector or a deputy appointed by him;

(c) An officer appointed by the Defence Department;

(d) The Harbour Engineer or other officer appointed by the Harbour Board concerned.

65. No person shall discharge or wash out tanks or allow petroleum or sludge to flow or be deposited from any tank or tank depot, storeship, pipe-line, barge, or lighter, or from any vessel—

(a) Into any harbour;

(b) Into a river, stream, channel, or drain flowing or discharging into any harbour; or

(c) On to the foreshore of any harbour.

66. An application for a license for the storage in an above-ground-tank depot of petroleum in bulk in quantities exceeding 5,000 gallons shall be accompanied by a plan of the premises, in duplicate, drawn to scale, showing all buildings and works on such premises, and all buildings and works situated within 100 ft. of the boundaries of the land comprising such premises. Such plan shall, if approved, be included in and form part of any license issued in respect of such premises.

67. Every above-ground-tank depot in which petroleum in bulk is stored shall be constructed of sufficient strength to hold the contents safely. It shall be constructed of metal or, in the case of fuel-oil, may be built of reinforced concrete. Every such tank shall be efficiently ventilated and electrically grounded, and, except in the case of floating-roof tanks, all ventilators or other openings in the tank shall be screened with wire gauze of not less than 28 meshes to the linear inch.

68. Prevention of outflow from every above-ground-tank depot shall be secured by the excavation of a well or pit; or by the erection of a mound of earth or a wall of brick, stone, or concrete; or in other approved manner enclosing a space sufficient to contain the full volume of petroleum capable of being held by the tank or tanks. Such enclosed space shall be occupied only by the storage tank or tanks and such settling and measuring tanks, pumps, piping, valves, and other necessary appliances as may be approved.

69. No water shall be allowed to accumulate in any tank depot. Drainage from the depot shall be provided either by pumping or by a pipe carried through the wall of the depot and actuated by a valve outside the depot. Such valve shall be kept closed except when water is being actually removed from the depot. An approved petroleum trap shall be installed in the drainage line inside the depot.

70. All buildings which are situated on premises licensed for the storage of petroleum and in which petroleum is used or is kept or stored otherwise than in bulk shall comply in all respects with the terms of the license and Parts V (a) and VI of these regulations.
