Handling in special circumstances
430. (1) Explosives affected by cold temperatures shall only be used as recommended by the manufacturer.
(2) Waste and deteriorated, damaged or time-expired explosives shall be destroyed promptly by
(a) a blaster;
(b) a representative of the explosive manufacturer; or
(c) a qualified member of the Royal Canadian Mounted Police, the Department of National Defence, the Explosives Division of Natural Resources Canada or the Royal Newfoundland Constabulary using methods approved by the manufacturer.
Preparing the blast loading
431. (1) A detonator shall be kept and handled separately from other types of explosives until the last practicable moment when the blaster primes the charge.
(2) A hole shall not be loaded with an explosive before it is necessary before firing.
(3) A nitroglycerine-based product shall not be unwrapped.
(4) A non nitroglycerine-based product shall remain in its original wrapping until the last practicable moment before use.
(5) An electric detonator shall be kept shunted or short circuited until it is used, except during the testing of the detonator.
(6) An employer shall ensure that tamping rods and other similar devices are made of wood or other non-sparking materials.
(7) Primed explosives shall not be slit or tamped.
(8) Undue pressure or pounding shall not occur during tamping.
(9) Where pneumatic loading of ammonium nitrate and fuel oil occurs, only a semi-conductive hose shall be used and the loader shall be effectively grounded and the bottom priming of drill holes shall be done with non-electrical initiation.
(10) A blaster, using a blasting meter, shall personally test the continuity of a loaded hole containing an electric detonator before the hole is stemmed with a suitable material.
432. (1) Only a federally authorized safety fuse assembly shall be used and fuse capping is not permitted.
(2) A safety fuse assembly shorter than one metre shall not be used.
433. (1) The location of a loaded hole shall be visually identified by either placing individual markers at the hole or marking off the perimeter of the area containing loaded hole by a display of warning tape or other highly visible indicator.
(2) A hole which has been loaded, but not fired by the end of the working day, shall not be left unattended, whether primed or not.
(3) A worker shall be posted to ensure that a hole is not tampered with when the work crew is absent from the site.
434. (1) A vehicle or other mechanical equipment shall not be driven or moved over an explosive, a blasting accessory or a hole containing an explosive.
(2) A blaster shall ensure that unused explosives and detonators are returned to the day box or magazine before the blast is initiated.
435. (1) Where there is danger from extraneous electricity, a blasting operation shall be fully non-electric.
(2) A blasting operation or handling of an explosive shall not be carried out on the approach of or during an electrical storm and persons shall remain outside the danger area at that time.
To minimize hazards from radio frequency energy, electrical blasting shall not be carried out at a distance from a transmitter less than shown in Table 1 or Table 2, whichever is applicable:
