Part 36 Mining

Section 639 Testing and initiation

Circuit testing devices are specifically designed for that purpose and must be used according to the manufacturer’s specifications. The use of an inappropriate testing device could potentially result in a non-initiation event or an unnecessary misfire situation.

For hazardous sites and coal mines, explosive initiating and testing devices must be approved by CANMET or by the Director. Devices must be specifically designed and manufactured for use in flammable and explosive atmospheres.
