There is a newer version of the New York Consolidated Laws
2006 New York Code - Acetylene.
§ 27-4101 Acetylene. a. Approval of generator. It shall be unlawful to generate acetylene, except in a generator or other suitable apparatus of a type for which a certificate of approval shall have been issued; provided, however, that nothing contained in this section shall be construed as requiring a certificate of approval for an acetylene generator having a carbide capacity not exceeding five pounds. b. Containing building. Each building or compartment used for the generation and compression of acetylene, to a pressure greater than fifteen pounds to the square inch, shall be designed and constructed in accordance with all applicable provisions of the building code, and shall be used for no other purpose. c. Stationary apparatus. Each stationary apparatus for generating acetylene shall be equipped with liquid seals, a safety valve, a blow-off valve or other automatic appliance for limiting the pressure of the gas to not more than fifteen pounds to the square inch at a temperature of seventy degrees Fahrenheit. The apparatus shall be installed in a waterproof compartment having the floor, walls and roof of brick or reinforced concrete. The size of such compartment shall not exceed that required to allow the free operation of the apparatus and the storage of the necessary carbide. Each such apparatus shall bear the name of the manufacturer and the year of its manufacture, and shall be identified by a serial number. d. Compression. It shall be unlawful to compress acetylene, or transport, store or sell acetylene compressed to a greater pressure than two hundred fifty pounds to the square inch at a temperature of seventy degrees Fahrenheit. e. Dissolving and absorbing. It shall be unlawful to generate, transport, store or sell acetylene compressed to a pressure greater than fifteen pounds to the square inch, except when it be dissolved in acetone, or other similar solvent, and simultaneously absorbed into asbestos or other suitable porous material, and confined in a tank or cylinder of a type for which a certificate of approval shall have been issued. f. Liquid. It shall be unlawful to generate, manufacture, transport or sell any liquid acetylene. g. Residue of carbide. All solid residue of calcium carbide shall be promptly removed from the building and disposed of; and it shall be unlawful to discharge any such residue into a public drain or sewer. h. Storage tanks. All tanks and cylinders used for the storage of acetylene under pressure, having originally passed the required test, shall be exempt from the quinquennial test, but shall be designed and constructed to withstand a pressure of twelve hundred pounds to the square inch without rupture, and to withstand a pressure of at least five hundred fifty pounds to the square inch without exhibiting strain beyond the point of usefulness. Each tank and cylinder, used for the storage of acetylene under pressure, shall be tested to withstand a pressure of five hundred fifty pounds to the square inch; and it shall be unlawful to generate, transport, store or sell acetylene in an apparatus, tank or other container in the construction of which unalloyed copper is used. It shall be unlawful to store any tank or cylinder containing acetylene in quantities aggregating more than twenty-five hundred cubic feet in any building except under a special permit. Acetylene contained in tanks or cylinders, attached to vehicles and ready for use, shall not be included in computing the quantity stored in any building. i. Use in public entertainment. It shall be unlawful to generate acetylene in connection with a motion picture show or exhibition or other public entertainment.
j. Ventilating, heating and lighting. Each building or compartment used for the generation or compression of acetylene shall be well ventilated, shall be heated only by steam or hot water, and shall be artificially lighted only by electric lights having airtight bulbs, globes or tubes. k. Fire prevention. It shall be unlawful to allow any stove, forge, torch, boiler, furnace, flame or fire, or any electric or other appliance which is likely to produce an exposed spark, in any compartment used for the generation or compression of acetylene.
