Part 36 Mining

Section 611 Magazines

This section applies to an explosive magazine intended for use in an underground mine. Magazines at a surface mine must be certified by federal authorities.

Explosives are classified as hazardous materials. Due to the confinement of an underground working environment, the effects of an unplanned explosion could be catastrophic to mine workers. Explosive products cannot be stored in an underground mine except in a magazine that meets very strict conditions.

According to the OHS Code, the minimum requirement for an underground explosive storage magazine is that the facility be designed and certified by a professional engineer. Further, the Director must also approve the magazine to ensure that an acceptable standard has been maintained.
