PART XIX GENERAL BLASTING — Definitions

"blaster" means a person who holds a valid blaster's certificate granted by the province;

"blasting activity" includes storing, handling, transporting, preparing and using explosives, and drilling conducted at a blasting area or in relation to the use of explosives;

"blasting area" means the zone extending at least 50 metres in all directions from the place in which explosives are prepared, handled or loaded for firing, or in which misfired explosives exist or are believed to exist and from which hazards shall be excluded to avoid an accidental explosion;

"blasting machine" means an electrical or electro-mechanical device which provides electrical energy for the purpose of energizing electric detonators and electrical circuits for continuity, resistance, stray currents and other pertinent measurements;

"blasting switch" means a device used to permit the firing of electric blasting circuits from power lines and constructed so that the door may be closed and locked with the switch in the "OFF" position;

"danger area" means the zone in which there exists a possibility of hazard to person or property from fly rock, fume, air blast or ground vibrations;

"day box" means a portable unit used for keeping explosives in during the day and which meets the requirements of "Storage Standards for Industrial Explosives" published by the Explosives Division of Natural Resources Canada;

"detonator" includes electric blasting caps of instantaneous and delay types, blasting caps for use with safety fuses, detonating cord, delay connectors and non-electric instantaneous and delay blasting caps which use detonating cord, shock tube, gas tube and another replacement for electric leg wires and another similar device;

"explosive" means a substance, including a detonator or primed explosive, that is manufactured or used to produce an explosion by detonation or deflagration and that is regulated by the Explosives Act (Canada), but does not include ammunition for weapons or fireworks;

"extraneous electricity" means unwanted electrical energy greater than 50 milliamps that is present at the blasting area that could enter an electric blasting circuit including stray current, static electricity, radio frequency energy and time-varying electric and magnetic fields;

"magazine" means a fixed unit used for the unattended storage of explosives overnight and which meets the requirements of the "Storage Standards for Industrial Explosives" published by the Explosives Division of Natural Resources Canada;

"misfired hole" means a charge of explosives in a hole or part of a hole which has failed to fire as planned and "misfire" has a corresponding meaning;

"prime charge" means to position a detonator for use in firing an explosive charge;

"primed explosive" means an explosive containing a detonator; and

"stemming" means clean, crushed angular shaped stone, 12.5% of the borehole diameter in size, which provides confinement for explosive energy.
