(1) This regulation applies if there is a misfire after an electric detonator has been used.
(2) The shotfirer must—
(a) short-circuit the firing cable and the lead wires of the detonator before attempting to treat the misfire; and
(b) if the shotfirer proposes to use a procedure under regulation 242—ensure, if practicable, that the lead wires from the detonator in the misfired blast hole are firmly secured to a fixed object so as to allow the recovery of the detonator.
