Part 36 Mining

Section 548 Fire precautions

(1) An employer at an underground coal mine must ensure that

(a) not more than 700 litres of flammable liquid is stored in the mine unless the flammable liquid is stored in a fireproof receptacle or chamber,

(b) mine material likely to cause a fire does not accumulate in any working part of the mine,

(c) mine material likely to cause a fire is kept in fireproof containers that are removed and disposed of at regular intervals,

(d) flammable construction material is not used in an area of the mine in which stationary compressors or other stationary equipment capable of producing more than 400 kilowatts is installed,

(e) tarred or other building paper is not used in the mine, and

(f) propane is not used in the mine except in mine heaters in portal structures.

(2) An employer at an underground coal mine must ensure that the following are constructed of non-flammable material or treated to make them fire resistant:

(a) underground portals;

(b) main fan installations;

(c) booster fan installations;

(d) ventilation air crossings;

(e) stoppings, regulators and doors.

(3) An employer at an underground coal mine must ensure that workers use dust-suppression devices if concentrations of dust may be hazardous.

(4) An employer at an underground coal mine must ensure that unattended conveyor belt transfer points have automatic fire warning devices that sound an alarm in the manned surface control room.

(5) An employer at an underground coal mine must ensure that equipment brought into the mine by workers uses fire resistant hydraulic fluids that meet the requirements of CSA Standard CAN/CSA-M423-M87 (R2007), Fire-Resistant Hydraulic Fluids.

(6) Subsection (5) does not apply to the following vehicle components:

(a) axles;

(b) fluid couplings;

(c) braking systems that employ totally enclosed friction elements immersed in a cooling liquid; or

(d) braking systems whose hydraulics are independent of any other hydraulic system.

(7) Despite subsections (5) and (6), the Director may approve a vehicle that uses an automatic fire suppression system and associated automatic engine shutdown provided the mine uses a continuous fire detection and gas-monitoring system.
