68-105-102. In addition, the
following definitions are applicable to the standards adopted in rule

missiles and concussion.
(b) "Blast
site " means the area where explosive material is handled during loading of the
blast hole, including fifty (50) feet in all directions from the perimeter
formed by the loaded holes. A minimum of thirty (30) feet can replace the fifty
(50) feet requirement if the perimeter for loaded holes is marked and separated
from the non-blast site areas by a barrier. The fifty (50) feet distance
requirements, as applicable, apply in all directions along the full depth of
the blasthole. In underground blasts, at least fifteen (15) feet of solid rib,
pillar or broken rock can be substituted for the fifty (50) feet
distance.
(c) "Blast zone " means
the area beyond the blast area that may be influenced by blasting operations.
Areas beyond the initial blast area must have reasonable precautionary measures
such as posting of signs and guards and redirection of traffic.
(d) "Binary explosive " means a blasting
explosive formed by mixing or combining two (2) plosophoric materials which
must be specifically packaged for that purpose (for example, ammonium nitrate
and nitromethane).
(e) "Bulk mix "
means a mass of explosive material prepared for use in bulk form without
packaging.
(f) "Bulk mix delivery
equipment" means equipment (usually a motor vehicle with or without a
mechanical delivery device) that transports explosive materials in bulk form
for mixing or loading directly into boreholes or both.
(g) "Fire-resistant construction " means
construction designed to provide reasonable protection against fire. For
exterior walls of magazines constructed of wood, this is defined as the fire
resistance equivalency provided by sheet metal of not less than twenty-six (26)
gauge.
(h) "Flyrock " means any
dirt, mud, stone, fragmented rock or other material that is displaced from the
point of the blast, traveling in the air or along the ground.

involved in making a product or device that is intended to explode.
(m) "Plosophoric materials " means two (2) or
