226Electric firing near source of electric power

226 Electric firing near source of electric power (1) If electric firing is carried out near a source of electric power or a power or lighting cable, all proper precautions must be taken to prevent the firing cables, connecting wires and detonator lead wires from coming into contact with, or being affected by, any electrical leakage or induction from the cable or source of electric power. (2) Storage batteries and dry cells must be kept at least 10m from— (a) any firing cable; and (b) any part of a firing circuit; and (c) any place where electric detonators or electric fuse lighters are exposed. (3) Subsection (2) does not apply if the batteries or dry cells are adequately covered to prevent any likelihood of them causing the accidental firing of a detonator or fuse lighter.

(4) Electric firing in a mine or quarry must not be undertaken near any electrified trolley wire, underground power cable or high-voltage overhead powerline. (5) Subsection (4) does not apply if an inspector gives the shot-firer written approval for the electric firing.
