Part 33 Explosives Safety

Section 517 Seismic blasting and drilling

Subsection 517(1)

The special needs of seismic blasting and drilling have been grouped together in this section. Unless stated otherwise, all other requirements of the OHS Code also apply to seismic blasting and drilling activities.

Subsections 517(2) and 517(3)

Seismic blasting operations require running water when holes are drilled in the ground. During winter operations, the only practical method of warming water tanks and valves on seismic drills in remote locations under severe climatic conditions is to use an open flame. Recognizing that under normal circumstances open flames are not permitted within 15 metres of explosives but that the practice is widely followed by industry, the listed conditions must be met so that the practice can be performed safely.
