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.

Summary of Corrections

December 2016

The table below lists the minor corrections made to Western Canada Mine Rescue Manual. These changes only reflect typographical errors and basic technical errors. Other issues regarding material will be updated and revised by the steering committee.

Page Edits made in manual

Inserted a reference to Table 3.1 under “Prior to travelling on ice”:

“Table 3.1 indicates the weight that will be supported by varying thicknesses of clear blue lake-ice . . .”


Updated definition:

Alternating Current (AC) refers to when a current in a circuit reverses polarity or changes direction in current flow . . .”


Added a word under “Voltage Gradient on the Ground” to improve understanding:

“These rods are typically driven 2.5 m (8 ft) or more into the ground to ensure good contact with the ground.”


Corrected formula error under “Combined Threshold Limit Values”:


Corrected error under “Properties”:

“Air is colourless, odourless, tasteless and non-flammable.”


Reworded sentence under “Properties” to reduce confusion:

“Carbon dioxide is a colourless, odourless gas that when breathed in large quantities may cause a distinctly acidic taste.”

5-11 and   5-22

Revised explosive limit of hydrogen to 4–74% for consistency.

Note: There are multiple sources for determining explosive limits of chemicals. Steering committee will determine which source will be referenced during next full manual revision and make further updates as required.

6-1 to 6-8

Corrected page formatting


Updated categories of hazardous atmospheres under “Introduction” for consistency:

“There are four categories of hazardous atmospheres:

  • Toxic
  • Oxygen deficiency/asphyxiating gases
  • Explosive/ flammable gases or vapours
  • Smoke, aerosols, fumes (particulate contaminants)”

Corrected chapter heading:

“Western Canada Mine Rescue Manual”


Replaced “relative density” with “vapour density” under “Gases and Vapours”. Relative density is compared to specific density which is more applicable to liquids or solids.


Changed the photo under “Hand-Operated Pump” to hand-operated pump type extinguisher.


Added to photo of single pulley

Corrected “break bar” to “brake bar” under “Break bar racks”


Corrected spelling under “Bowline” to “A loop that will not jam, slip, or fail


Corrected spelling under “Prusik” from “breaks” to “brakes”


Changed the volume calculation to a more realistic example. It was correct but unrealistic.

12-9 and 12-10

Matched the images of mine plans with their descriptions.


Changed phases of fire from “five” to “four” under “Underground Mine Fires”
