Part 36 Mining

Section 636 Unused explosives

Subsection 636(1)

The return of unused explosives allows the employer to track inventory and ensures no explosive material is left in or around the mine. Even boxes used to carry explosives are treated as though they contain explosive residues and are destroyed according to the manufacturer’s specifications. Unused explosives must be returned to the magazine and the magazine record adjusted accordingly.

Subsection 636(2)

Even small quantities or portions of explosives that are blown out of a blasted hole can be a hazard. As such, they must be treated as a misfire and handled according to defined procedures.
