Part 36 Mining

Section 725 Fan operating procedures

Subsection 725(1)

If a booster fan or auxiliary fan stops, workers must be evacuated to a place that is adequately ventilated. Since the loss of ventilation can result in a rapid deterioration of air quality, a competent worker must test the affected area before workers are allowed to return or enter the area. If air quality is below acceptable levels, workers must not return to this area until adequate ventilation has been re-established.

Subsection 725(2)

Areas affected by a stopped auxiliary fan require testing for flammable gases before they can be declared safe and the fan restarted. Testing an area for flammable gases and making the decision to restart an auxiliary fan must be done by a competent worker who is fully aware of the risks and importance of these activities. In addition to posting the declaration that it is safe to restart a fan, the supervisor must include it in his written shift report.

Subsection 725(3)

The code of practice for restarting both booster and auxiliary fans underground must be posted in a conspicuous location at the mine. Section 8 of the OHS Regulation requires that procedures in a code of practice be in writing and available to workers.

Subsection 725(4)
