PART XXIX UNDERGROUND OPERATIONS — Fueling vehicles underground

except in the case where it is not practicable, the engine is fuelled in a fueling station;

a fueling station

has a concrete floor, (ii) has a curb or sump to contain spills of fuel, (iii) has a supply of noncombustible absorbent material to be used to absorb a spillage of fuel that could occur, (iv) is conspicuously marked by signs bearing the words "Shut Off Engine While Refuelling" and "No Smoking",

is designed and protected to prevent inadvertent entry of an uncontrolled motor vehicle, (vi) is located so that in the event of a fire or explosion in the fuelling station there will be a minimum effect on working areas of the mine or on underground installations, including shafts, magazines, refuge stations, transformer installations and other installations, (vii) provides clearance around the vehicles being fuelled to permit the safe performance of all work being performed, and (viii) is separate from a service garage;

before refuelling, the engine is shut off and the battery isolated;

where a mobile fuelling supply tank is used, the tank is of an approved design and is clearly labelled with "no smoking" signs; and

arrangements are made so that a spillage in the fuelling operation is removed at once, deposited in a fireproof receptacle and removed without undue delay.
