Western Canada Mine Rescue Manual

Every mine has to maintain a mine rescue team to help ensure the safety of workers and property on mine sites throughout B.C., Yukon, Northwest Territories and Nunavut. This manual has been crafted to demonstrate the basic equipment, procedures, practices, and principles that mine rescue trainees need to know before they respond to incidents at surface and underground mining operations.
