PART XIV
STORAGE OF DANGEROUS PETROLEUM IN TANKS IN QUANTITIES EXCEEDING 9,092 LITRES
55. Except as hereinafter provided, no new licence shall be granted nor shall any licence be renewed for any installation intended or used for the storage of dangerous petroleum in tanks in quantities exceeding 9,092 litres unless rules 56 to 70 inclusive are complied with:
Provided that —
(i)
the Director may at his discretion grant exemptions from the operation of any of the stipulations contained in these Rules, and may license any installation which was already in existence and licensed and used for such storage immediately prior to 24th December 1926 and which complied with the rules relating to such storage then in force; and
(ii)
nothing herein affects rule 63.
56. A plan of every installation intended for the storage of dangerous petroleum in tanks in quantities exceeding 9,092 litres shall be deposited with the Director, and shall show the boundaries of the installation and the position and nature of every building within 45 metres of such boundaries to a scale not smaller than 10 metres to 2.5 centimetres, and plans as required by the Building Control Act [Cap. 29] and the regulations made thereunder shall also be submitted.
57. No installation shall be for a quantity exceeding 1,363,800 litres without the special sanction in writing of the Director.
58. For every installation for a quantity not exceeding 1,363,800 litres the following rules shall apply:
(a)
except as provided in paragraph (e), every tank shall be at least 30 metres from any building used as a dwelling-house or from any building in which fire is used and shall be at least 9 metres from any other building irrespective of its use;
(b)
not more than 3 horizontal or vertical tanks shall be installed in any one group. The distance separating any two tanks both of which are entirely buried beneath the level of the ground or covered with at least 0.6 metre of earth shall be not less than 0.6 metre; the distance separating any other two tanks in one group shall be not less than the diameter of the larger of two adjacent tanks. Each such tank shall be at least 7.5 metres from the boundary of the installation;
(c)
every tank shall be cylindrical in shape and placed on a firm foundation. No horizontal tank shall exceed 136,380 litres capacity and the total capacity of any group of horizontal tanks shall not exceed 409,140 litres; there shall be a minimum distance of 7.5 metres between any two horizontal tanks which are not in the same group. Vertical tanks shall not exceed 7.8 metres in height or 11 metres in diameter;
(d)
except in the cases mentioned in paragraph (e) every tank or group of tanks shall be surrounded by a bund of such dimensions and substantial construction that the total quantity plus 10% of dangerous petroleum contained in the tank or tanks could be altogether contained in the enclosure formed by such bund (referred to in this paragraph and in rule 60 as the bunded area) and could not escape therefrom in the form of liquid whether under the action of fire or otherwise and the bunded area so far as not occupied by the tank or tanks must be kept entirely free and unoccupied. The bund may be constructed of earthen banks with a core of puddled clay or of reinforced concrete and must be so constructed as to withstand any pressure to which it may be subjected from interior or exterior flooding;
(e)
provided that —
(i)
if a tank is entirely buried beneath the level of the ground or covered by at least 0.6 metre of earth such tank shall be not less than 9 metres from any building; and
(ii)
paragraphs (a) and (d) shall not apply to tanks buried beneath the level of the ground, and paragraph (a) shall not apply to tanks covered with at least 0.6 metre of earth; and
(f)
within the undermentioned distances, that is to say —
(i)
within 9 metres of any tank, used for the storage of dangerous petroleum, which is entirely buried beneath the level of the ground or covered with at least 0.6 metre of earth; or
(ii)
within 30 metres of any other tank or of any building used for the storage of dangerous petroleum,
no person shall use a naked light and all electric wiring must be carried in strong metal tubing with screwed joints and must be suitably earthed, all switches and fuses being placed in positions approved by the Director.
59. For every installation for a quantity exceeding 1,363,800 litres, the following rules shall apply:
(a)
every tank shall be at least 36 metres from any building used as a dwelling-house or other building in which fire is used, and at least 12 metres from any building irrespective of its use;
(b)
every tank shall be cylindrical in shape and placed on a firm foundation. Horizontal tanks shall not exceed 136,380 litres capacity and vertical tanks shall not exceed 7.8 metres in height and 11 metres in diameter;
(c)
the distance separating any two tanks in one group and the distance from the boundary of the installation shall be as provided in rule 58(b);
(d)
every tank or group of tanks shall be surrounded by a bund of the dimensions and construction provided in rule 58(d); and
(e)
within the undermentioned distances, that is to say —
(i)
within 12 metres of any tank, used for the storage of dangerous petroleum, which is entirely buried beneath the level of the ground or covered with at least 0.6 metre of earth; or
(ii)
within 36 metres of any other tank or of any building used for the storage of dangerous petroleum,
no person shall use a naked light and all electric wiring must be carried in strong metal tubing with screwed joints and must be suitably earthed, all switches and fuses being placed in positions approved by the Director.
60.
—(1) In the case of canning or filling tanks of less than 90,920 litres capacity the distance from the main tank to the canning or filling tanks shall not be less than the diameter of the canning or filling tank and such canning or filling tank shall be at least 30 metres from any building used as a dwelling-house or building in which fire is used and at least 12 metres from any other building.
(2) Canning or filling tanks may be within the same bunded area as the main tank provided the cubic capacity of the bunded area exceeds the combined storage capacities of the main tank and canning or filling tanks.
(3) Storage sheds or canning sheds in which small packages such as drums or cans are filled shall be separate buildings constructed of masonry or other non-inflammable material and shall be at least 12 metres from the main tank or canning or filling tanks. Each building shall be surrounded with a masonry wall or embankment so formed that it shall be capable of containing the whole of the dangerous petroleum which could be contained in the building.
(4) Filling sheds or buildings in which tank lorries or railway tank-cars are filled shall be at a distance of not less than 12 metres from a storage godown or tank.
61. Every tank or group of tanks shall be surrounded at a distance of not less than 7.8 metres by a wire fence 2.4 metres high with suitable gates, which must remain locked except —
(a)
when delivery to and from the tank is taking place;
(b)
when the necessary daily tank gauge readings are taken;
(c)
in cases of necessity, such as repairs, cleaning and painting the tanks, provided that such work is done between sunrise and sunset;
(d)

63. The Director may, on receipt of an application in relation to any particular installation or part of an installation and provided that he is satisfied that such waiver or modification as hereinafter mentioned will not render the installation unsafe, modify or waive, upon and subject to such terms as he thinks fit, any of the following stipulations in these Rules:
(a)
(b)
the stipulations as to maximum capacities of 136,380 and 409,140 litres contained in rule 58(c) and of 136,380 litres contained in rule 59(b).
