Part 33 Explosives Safety

Section 499 Safe distance

The minimum safe distance recognized as an industry-wide practice in seismic blasting operations is 30 metres. Unlike other industries, charge size and depth remain relatively constant, permitting the use of a single safe working distance.

In the case of operations involving pyrotechnics and special effects, the distances cited in the referenced NFPA standards must be followed.
