the meaning of the said Act, and the provisions of the said Act (subject to such exceptions, limitations, and restrictions as may be specified in the Order) shall accordingly extend to any such substance in like manner as if it were included in the term explosive in the said Act: And whereas acetylene when in admixture with air or oxygen is specially dangerous to life or property by reason of its explosive properties: And whereas the provisions of section one of The Rules Publication Act, 1893, have been complied with: Now, therefore, Her Majesty is pleased by and with the advice of Her Privy Council to order and declare and be it ordered and declared as follows: Acetylene when in admixture with atmospheric air or with oxygen gas in whatever proportion and at whatever pressure and whether or not in admixture with other substances shall be deemed to be an explosive within the meaning of the said Act. And whereas by section forty-three of the Explosives Act, 1875, it is provided that Her Majesty, from time to time by Order in Council, may prohibit, either absolutely or except in pursuance of a licence of the Secretary of State under the said Act, or may subject to conditions or restrictions the manufacture, keeping, importation from any place out of the United Kingdom, conveyance, and sale or any of them, of any explosive which is of so dangerous a character, that in the judgment of Her Majesty it is expedient for the public safety to make such Order : And whereas it is in the judgment of Her Majesty expedient for the public safety that acetylene in admixture with air or oxygen, when an explosive within the meaning of this Order, shall be prohibited: Now, therefore, Her Majesty is pleased, by and with the advice of Her Privy Council, to order and prescribe that acetylene in admixture with air or oxygen, declared to be an explosive by this Order, shall be prohibited from being manufactured, imported, kept, conveyed, or sold. Provided that nothing in this Order shall apply to acetylene in admixture with air when such admixture takes place only in a burner or contrivance in which the mixture is intended to be burnt. Provided also that nothing in this Order shall be held to apply to an admixture of acetylene and air which may unavoidably occur in the first use or re-charging of an apparatus, properly designed and constructed with a view to the production of pure acetylene.

(For Order No. 5a see p. 280.) Explosives Act, 1875. WHEREAS by an Order in Council, dated November 26, 1897, made under section 104 of the Explosives Act, 1875, it is declared that acetylene when liquid, or when subject to a certain degree of compression, shall be deemed to be an explosive within the meaning of the said Act: And whereas by the said Order in Council it is provided that if it be shown to the satisfaction of the Secretary of State that acetylene, declared to be an explosive by the said Order when in admixture with any substance, or in any form or condition, is not possessed of explosive properties, the Secretary of State may by Order exempt such acetylene from being deemed to be an explosive within the meaning of the said Act: And whereas it has been shown to the satisfaction of the Secretary of State that acetylene, when in admixture with a gas manufactured from mineral oil (hereinafter referred to as oil-gas) in certain proportions, and not compressed beyond a certain pressure, is not possessed of explosive properties: Now, therefore, in exercise of the powers aforesaid, I, one of Her Majesty's Principal Secretaries of State, hereby order as follows: Acetylene in admixture with oil-gas in a proportion not exceeding twenty parts by volume of acetylene in every one hundred parts of the mixture, when subjected to a pressure not exceeding one hundred and fifty pounds to the square inch, shall not be deemed to be an explosive within the meaning of the said Act. Provided that the acetylene and oil-gas shall be mixed together in a chamber or vessel before the gases are subjected to compression. WHITEHALL, M. W. RIDLEY. March 28, 1898. STATUTORY RULES AND ORDERS, 1901. No. 310. EXPLOSIVE SUBSTANCE. ORDER OF SECRETARY OF STATE (No. 6), DATED APRIL, 10, 1901, RELATING TO ACETYLENE COMPRESSED INTO POROUS SUBSTANCES WITH AND WITHOUT ACETONE. Explosives Act, 1875. WHEREAS by an Order in Council dated 26th November, 1897, made under Section 104 of the Explosives Act, 1875, it is declared that acetylene when liquid or when subject to a certain degree of compression, shall be deemed to be an explosive within the meaning of the said Act. And whereas by the said Order in Council it is provided that if it be shown to the satisfaction of the Secretary of State that acetylene, declared to be an explosive by the said Order, when in admixture with any substance, or in any form or condition, is not possessed of explosive properties, the Secretary of State may, by Order, exempt such acetylene from being deemed to be an explosive within the meaning of the said Act. And whereas it has been shown to the satisfaction of the Secretary of State that acetylene, when compressed into a certain porous substance, and into a certain other porous substance containing acetone, is not possessed of explosive properties. Now, therefore, in exercise of the powers aforesaid, I, being one of His Majesty's Principal Secretaries of State, hereby order as follows: Subject to the conditions hereinafter specified, acetylene when compressed into porous substances, with or without acetone shall not be deemed to be an explosive within the meaning of the said Act, provided that : (1) The porous substances to be used, with or without acetone, shall be similar in every respect to samples deposited at the Home Office. (2) The porous substance shall fill, as completely as possible, the cylinder or other vessel into which the acetylene is compressed. (3) The porosity of the substance shall not exceed eighty per cent. (4) Due precaution shall be taken to exclude air from every part of the apparatus before the acetylene is compressed. (5) Due precaution shall be taken to prevent undue rise of temperature in compressing the acetylene. (6) The pressure shall not exceed one hundred and fifty pounds to the square inch. (7) Every cylinder or other vessel into which acetylene is to be compressed shall be tested by hydraulic pressure of not less than double the pressure to which the vessel is to be submitted into use, such hydraulic pressure being maintained for a period of not less than ten minutes. (8) In the case where acetone is used for absorbing the acetylene, due precaution shall be taken that the quantity of acetone is such that when fully charged with acetylene. it does not completely fill the porosity of the porous substance. (9) The compression of the acetylene shall be carried out only on such premises as shall have been approved in writing by one of His Majesty's Inspectors of Explosives. (10) Every cylinder or other vessel in which acetylene has been compressed in virtue of this Crder shall be legibly marked with the words- "Acetylene compressed into porous substance exempted by Order of Secretary of State dated 10th April, 1901," together with the name of the firm by whom the vessel has been charged. (11) Every facility shall be given to His Majesty's Inspectors of Explosives to inspect the apparatus and methods by which the cylinders or other vessels are charged in virtue of this Order. WHITEHALL, April 10, 1901. CHAS. T. RITCHIE. APPENDIX XIV. LONDON COUNTY COUNCIL. REPORT AS TO LICENSED PREMISES IN THE COUNTY OF LONDON, UPON WHICH PETROLEUM, UNDER THE ACTS, IS USED IN TRADE OR MANUFACTURE. Presented to the Sanitary and Special Purposes Committee, November 14, 1890. PETROLEUM ACTS. In accordance with the instructions of the committee at their meeting on October 31, that I should prepare a report submitting a list of the businesses carried on in London in which petroleum spirit is used in manufacturing processes or otherwise, I have to report as follows: The following is a list of the businesses, in which petroleum is so used, carried on in the county of London under the licences of the Council: Dry Cleaners (21 licensed premises). Helmet Manufacturers (5 licensed premises). Tennis Shoe Manufacturers (4 licensed premises). Indiarubber Manufacturers (12 licensed premises). Waterproof Garment Manufacturers (41 licensed premises). Paint Manufacturers (6 licensed premises). Glove Cleaners (41 licensed premises). The licences granted in respect of all these businesses have special conditions attached, with a view to safety, and in some cases these conditions appear to be fully adequate, as they probably reduce the danger in the particular processes carried on to the minimum. In some ne of the businesses, however, it may be desirable to make some addition to the existing precautions. Whenever mineral spirit or its inflammable vapour is liable to be present in workrooms in dangerous quantity, the following precautions should, wherever possible, be adopted: |
