Part 36 Mining

Section 644 Signs

Subsection 644(1)

Any blast area must be clearly identified and access controlled. Detonating cord, non-electric tubing, detonating relays, fuses, and wires can easily be damaged by vehicles travelling over them. Depending on the status of blast preparation, there may also be a risk of premature detonation.

Subsection 644(2)

The presence of unauthorized manpower and equipment may introduce unintended hazards. As a result, the employer must train workers to ensure that they understand the hazards associated with a mine blast site. It must be clear to all personnel that the blaster in charge is responsible for control of access to the blast area by both personnel and vehicular traffic. The blaster’s approval should be obtained before any non-blasting personnel or equipment approach the defined blasting area.
