Part 36 Mining

Section 634 Damaged blasting wires

A damaged wire may not activate the charge because current is unable to pass through the wire to the charge. The result could be a misfire. For this reason any worker who inadvertently drives over or damages blasting lead wires must immediately report the occurrence to the blaster and the employer. Blast site control in such a case should also be reviewed.
