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.
