Part 33 Explosives Safety

Section 481 Priming

Charges must be primed as close to the site of their detonation as possible. This reduces or eliminates unnecessary handling of a charge that has been primed, limiting the possibility of injury from unintended detonation. No more explosive than is required to perform the work should be removed from the magazine. This eliminates unnecessary handling and reduces the possibility of an incident.

To prevent the unintended detonation of stored explosives, charges must not be primed in any location where explosives are stored.

Primed charges must not be assembled in advance of the hole drilling operation. Only one charge must be prepared and loaded at a time prior to moving to the next hole.
