Section 115. Explosives

Any chemical compound or mechanical mixture that
  is commonly used or intended for the purpose of producing  an  explosion
  and   which  contains  any  oxidizing  and  combustive  units  or  other
  ingredients in such proportions, quantities, or packing that an ignition
  by fire, by friction, by concussion, by percussion, or by  detonator  of
  any  part  of the compound or mixture may cause such a sudden generation
  of highly heated gases that the resultant gaseous pressures are  capable
  of  producing destructive effects on contiguous objects or of destroying
  life or limb.
