73. After the tanks in any tank depot have once been filled no person shall be permitted to enter any such tank without the authority of the manager or person in charge of the installation. Before permitting any person to enter such tank the Manager or person in charge shall ensure that the tank is thoroughly ventilated to remove vapour, and before permitting any repairs to be undertaken he shall take such measures as are necessary to ensure that the tank is found free from vapour after a test by a competent person, who shall furnish a certificate to this effect. Until the tank is certified free of dangerous vapour only portable safety-lamps, oil or electric, of a type approved for use in fiery coal-mines shall be taken into it, and until such certificate shall be granted the use of naked lights or electric lamps with wandering leads shall be strictly prohibited. The test of the tank for vapour shall be carried out in accordance with the Sixth Schedule to these regulations: Provided that this regulation shall not prevent a person from entering such tank for the purpose of examination or for minor repairs that do not involve the use of iron or steel tools, if such person is protected from the effect of vapour by a gas-mask of efficient construction, provided with a life-line, and attended by some person outside the tank.

74. No matches shall be taken into, and no smoking, naked lights, or fires shall be permitted in or about any premises used for the storage of petroleum in bulk, except in such buildings as may be specially set apart for the purpose, and suitable notices to this effect shall be conspicuously posted on the premises.

75. In all premises licensed for the storage of petroleum in bulk the ground in the interior of an installation shall be kept clean and free from goods of inflammable nature, waste vegetation, and rubbish.

76. Every above-ground-tank depot shall be separated from all protected buildings and works by not less than the appropriate distances prescribed in the following table: Provided that the Chief Inspector may authorize a reduced distance where in his opinion the public safety will not be unduly prejudiced thereby:—

(e) Storage of Dangerous Goods of Class III.

77. No person shall store calcium carbide on licensed premises otherwise than in a building so constructed as to comply with the following general conditions:—

(a) The building shall be externally unflammable (i.e., of brick, stone, or concrete, or externally covered with galvanized iron), if situated less than 10 ft. from any protected work.

(b) Except as may be approved by the Chief Inspector, calcium carbide shall not be stored within a building which is a protected work unless such building is built of brick, stone, or concrete, and the room or receptacle in which the calcium carbide is kept is on the ground floor and is of approved fire-resisting construction.

(c) The building or storage-room shall be efficiently ventilated to the outer air.

(d) The building shall be so secured as to prevent access by unauthorized persons, and shall be sufficiently weatherproof to prevent access of water to the place where the calcium carbide is stored.

(2) The provisions of this regulation shall not apply to the storage of a quantity of calcium carbide not exceeding 50 lb. contained in waterproof and airtight tins each containing not more than 7 lb.

78. The occupier of premises licensed for the storage of calcium carbide, and every person in or about the same shall comply with the following rules:—

(a) Calcium carbide shall be kept stored or conveyed only in strong metal vessels so constructed and closed as to prevent the admission of water and atmospheric moisture, each of which contains not more than 224 lb. of carbide. No more of these vessels than is necessary for immediate requirements shall be opened at one time, and then only for the time necessary for the removal of any required quantity of carbide.

(b) Only such other goods as may be approved shall be stored in the same building or room as calcium carbide.

(c) Only commercially pure carbide of calcium shall be kept on the premises.

(d) Unalloyed copper shall not be used in the construction of vessels or apparatus used for or with carbide of calcium and the gas produced therefrom.

(e) No appliance for generating acetylene gas other than a portable lamp shall be used on the premises except an apparatus of a type approved by the Chief Inspector, and clear instructions as to the management of the apparatus shall be kept conspicuously posted in the generator-house. The pressure in any acetylene-generating apparatus shall not exceed that of a column of water 250 in. in height. Oxy-acetylene welding shall not be carried on unless an efficient oxygen trap is provided on the acetylene supply-pipe to the blow-pipe in such manner as to prevent the possibility of oxygen finding its way to the acetylene generator.

(f) Suitable arrangements shall be made for the safe disposal of any residue of carbide of calcium removed from a gas-making apparatus, and such residue shall not be introduced into sewers or cesspools unless mixed with at least ten times its bulk of water.

(g) No artificial light capable of igniting inflammable vapour shall be taken into, and no person shall smoke in, any generator-house or calcium carbide storage place.

79. All phosphorus stored on licensed premises shall be kept completely covered with water in vessels of metal or other approved material of such construction as may be approved; provided that no more than 2 lb. of phosphorus shall be stored in any building which is a protected work unless such building is built of brick, stone, or concrete, and the room or compartment where the phosphorus is kept is of approved fire-resisting construction; provided further that only such other goods as may be approved shall be stored in any building or in any room or compartment in which phosphorus is kept.

(f) General.

80. Notwithstanding anything in these regulations in cases where the public safety will not be unduly prejudiced thereby a license may, with the approval of the Chief Inspector, be issued to store dangerous goods in the quantities stated in such license in a well-ventilated depot or storage place which does not otherwise comply with the requirements of this Part of these regulations. Such license may be issued either without restriction, or may be for a definite period only, or may be subject to cancellation under certain conditions.

81. Every depot established or maintained by a local authority shall comply with the provisions contained in these regulations regarding the construction, situation, and maintenance of depots on licensed premises.

82. The Minister may, by notice under his hand published in the Gazette, make, and may in like manner revoke, alter, or add to, special rules for the regulation of the persons managing or employed in or about any depot maintained by any local authority, or in or about any licensed premises, or storship, with a view to secure the observance of the said Act and these regulations therein, and the safety and proper discipline of the said persons and the safety of the public. Any person committing a breach of any such special rules shall be deemed to have committed a breach of these regulations, and shall be liable to a fine not exceeding £10.

PART VI.—USE OF DANGEROUS GOODS OF CLASS I FOR DRY CLEANING AND OTHER INDUSTRIAL PURPOSES.

83. In this Part of these regulations the term “dangerous goods” means dangerous goods of Class I; the term “use” means the use of dangerous goods for industrial purposes involving the exposure of such goods to the air in such manner that inflammable vapour can escape; and the term “workroom” means the room or place where dangerous goods are used.

84. No person shall use dangerous goods except in a workroom situated and constructed in accordance with these regulations.

85. Every workroom where dangerous goods are used or kept for use in quantities exceeding 3 gallons shall, as regards construction, comply with the following conditions:—

(a) The walls of the workroom shall be of brick, stone, or concrete, and the roof shall be of concrete not less than 6 in. thick.

(b) Where the workroom is situated within another building it shall have no openings to the interior of such building.

(c) The floor of the workroom shall be constructed of impervious non-inflammable material, approved by the Chief Inspector, in such manner as to prevent leakage.

(d) Windows (and skylights, if any) shall be of wired glass with incombustible frames.
