48. No building shall be licensed for the storage of dangerous petroleum in quantities exceeding 2,270 litres unless so constructed as to comply with the conditions laid down in these Rules.
49. A plan of every building intended for the storage of dangerous petroleum in quantities exceeding 2,270 litres shall be deposited with the Director, and shall show the position and nature of every other building within 60 metres of the first mentioned building 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:
Provided that in the case of any building lawfully used immediately prior to 24th December 1926 for the storage of dangerous petroleum in quantities exceeding 2,270 litres it shall not be necessary to deposit the plan unless the Director by notice in writing requires such plan to be deposited.
50. The following conditions shall be complied with in regard to every such building as is referred to in rule 48:
a building to be licensed shall be at such distance from any other building, and from the boundaries of the plot as shall be prescribed by the Director;
buildings to be licensed shall be constructed with external walls of brickwork of a thickness of not less than 35 centimetres and shall be rendered inside with cement plaster of a thickness of not less than 1.9 centimetres;
no one building shall contain more than 145,480 litres, and the storage of this quantity shall be allowed only when the building is divided into entirely separate compartments by a partition wall constructed in the same manner as the external walls and carried at least 0.9 metre higher than the external walls and of the same thickness throughout. The quantity to be stored in one such compartment shall not exceed 72,740 litres;
no building shall be of more than one floor and the floor area shall not exceed 6.5 square metres per 4,546 litres to be stored;
the roof shall be of reinforced concrete not less than 15 centimetres in thickness or of other materials approved by the Director;
such ventilators shall be fixed as shall be required by the Director;
the doors and window-shutters shall be of steel or iron 3 millimetres in thickness and shall be hung in iron or steel frames. The sills of door and windows shall not be less than 1.5 metres from the floor level;
all the floors shall be laid in cement concrete of a thickness to be approved by the Director and shall be watertight, and shall slope to a catch-pit of approved dimensions formed in cement concrete;

around the building there shall be a continuous masonry wall or embankment of a construction approved by the Director of such a height that the cubic capacity of the open space within the wall or embankment together with the cubic capacity of the building up to sill level shall exceed the total cubic content of the dangerous petroleum contained in the building. The Director may require the ground between the building and the wall or embankment to be covered with cement concrete. In the event of the building being divided into two compartments as provided for in paragraph (c) the area enclosed by the said wall or embankment shall be subdivided subject to the approval of the Director into two areas the cubic contents of each of which shall exceed the total quantity of dangerous petroleum to be stored in each compartment;
all rain-water pipes shall be carried above and out over the wall or embankment; and
all drains leading through the walls or embankment shall be of iron and shall lead into catch-pits and shall be provided with sluice valves capable of being opened to allow surface water to escape.
