21. No building shall be licensed for the storage of petroleum in quantities exceeding 400 cases unless so constructed as to comply with the conditions laid down in these Rules.
22. A plan of every building intended for the storage of petroleum in quantities exceeding 400 cases shall be deposited with the Director and shall show the position and nature of any other building within 45 metres of that 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 petroleum in quantities exceeding 400 cases it shall not be necessary to deposit the plan unless the Director by notice in writing requires such plan to be deposited.
23. Every such building as is referred to in rule 22 shall be of stone, brick, or other material approved by the Director and the following rules shall apply to all buildings erected, altered or adapted after 24th December 1926:
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 19 millimetres;
no one building shall contain more than 40,000 cases or 1,454,720 litres and the storage of this number of cases and quantity of petroleum shall be allowed only when the building is divided into independent compartments provided that no one compartment shall contain more than 10,000 cases or 363,680 litres;
no building or compartment shall be of more than one floor and the floor area of any one compartment shall not exceed 22 square metres per 1,000 cases intended to be stored;
where there is more than one compartment in any licensed building the walls between each compartment shall be constructed in the same manner as the external walls and shall be carried at least 0.9 metre higher than the external walls of the building and shall be of the same thickness throughout;
there shall be no communication between one compartment of a building and any other compartment thereof;
the roof shall be entirely constructed of non-inflammable materials, the trussing, tie-beams, tie-rods, supports, etc., shall be of iron or steel. The roof shall be covered with corrugated iron or approved tiles; the tie-beams of the roof shall be 0.6 metre higher than the storage limit. Such ventilators shall be fixed as shall be required by the Director;
the sills of all doors and windows shall be built at a height of not less than 1.5 metres from the floor level and there shall be no openings in the external walls below the level of the sills.

all the floors shall be laid in cement concrete of a thickness to be approved by the Director and shall be watertight;
at least two copper lightning-conductors shall be fixed to each building or compartment and shall lead to an earth-plate in a pit, well, river or the sea and be maintained in good order;
around the licensed building there shall be a continuous masonry wall or embankment of a construction approved by the Director, and of such a height that the cubic capacity of the open space within the wall or embankment together with the cubic capacity of the compartments up to sill level shall exceed the total cubic content of the 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;
a detached building of brick or other incombustible materials having the floor laid in cement concrete shall be provided for the soldering of tins at a distance of not less than 9 metres from the licensed building.

25. Naked tins shall not be stored above 3.9 metres from the floor level and a distinct black band 5 centimetres wide, the bottom of which shall indicate the limit above which such tins may not be stored shall be painted round the inside of each building or compartment and shall be kept distinguishable.
26. The soldering of tins, drums or other receptacles containing petroleum or the application thereto of any operation in which fire or heat is used is prohibited except in the soldering building provided and not more than 25 cases shall be kept in the soldering building at any one time.
