PART XIX GENERAL BLASTING — Drilling
429
(1) A drill hole shall be of a sufficient size to admit the free insertion of explosives to the bottom of the hole without ramming, pounding or undue pressure.
429(2)
Drilling shall not be done in a previously blasted area until the surface to be drilled is carefully examined for remnants of explosives or holes containing explosive materials.
429(3)
Where a remnant or a hole containing explosives is found, this explosive shall be dealt with as a misfire before drilling commences.
429(4)
Drilling shall not be done closer to a part of a hole containing an explosive than the distance equal to half the total depth of the hole being drilled and in no instance closer than 6 metres from a part of a hole containing an explosive.
429(5)
Notwithstanding subsection (4), where
429(a)
a blaster determines that a particular misfire cannot be more safely treated by another means and it is necessary to drill an adjacent hole in a manner inconsistent with subsection (4);
429(b)
the nature of the ground being drilled makes it necessary to load a hole immediately after it is drilled and to subsequently drill an adjacent hole in a manner inconsistent with subsection (4);
429(c)
a loaded hole caves in and a blaster determines that the unexploded hole cannot be reprimed or otherwise more safely treated, and it is necessary to drill an adjacent hole in a manner inconsistent with subsection (4); or
429(d)
it is necessary to use a drill to remove obstacles from a previously drilled hole which does not contain explosives and to do so would be inconsistent with subsection (4) a written safe work procedure, developed in consultation with a blaster, shall be followed where the employer has notified the minister in writing that the safe work procedure is being implemented, including the reason for its implementation.
429(6)
The safe work procedure referred to in subsection (5) shall be authorized in writing by the minister before the commencement of the work.
429(7)
Where a safe work procedure referred to in subsection (5) is implemented, the details of the procedure and the reasons for its implementation shall be communicated to persons remaining in the blasting area who shall adhere strictly to its terms.
