2006 New York Code - Restrictions.

 
    §  27-4068  Restrictions.  The  commissioner  may,  by rule, prescribe
  requirements  for  the  safe  manufacture,  storage,  sale  and  use  of
  combustible mixtures, and prohibit or restrict the manufacture, storage,
  sale  or  use of such a mixture in any container, equipment, building or
  place in the interest of public safety.
    b. A combustible mixture shall be kept  separate  from  any  substance
  with  which  it  is  incompatible,  when  such mixture and substance are
  stored or used in containers having a capacity of more than five  pounds
  or  one-half  gallon.  Except  where  this  chapter,  a rule of the fire
  commissioner, or other applicable  law,  rule  or  regulation  specifies
  greater protection, such separation shall be maintained at a distance of
  not  less  than twenty feet, by a noncombustible partition extending not
  less than eighteen inches above and to the sides of the stored  mixtures
  or  substance,  by storing such mixture and substance in a metal storage
  cabinet, or by other means acceptable  to  the  fire  commissioner.  For
  purposes  of  this  section, "incompatible" shall mean that such mixture
  and substance, if mixed, could explode, generate heat,  gases  or  other
  byproducts, or otherwise react in a manner potentially hazardous to life
  or property.
    c.  The  owner  of any establishment in which combustible mixtures are
  being manufactured, stored or used,  and  all  persons  engaged  in  the
  manufacture,  storage or use of such combustible mixtures thereat, shall
  be  familiar  with  the  hazardous  nature  of  the  mixtures  and   the
  appropriate  actions  to be taken in the event of spill, leak or fire. A
  certificate of fitness shall be obtained where required by rule  of  the
  fire commissioner.
