Summary: The operator of a loader noticed flames from the rear of the loader when in the decline. He activated the fire suppression and parked the loader safely. The fire was extinguished with the onboard fire suppression. Initial investigation identified the ignition source was electrical as the fire originated around the battery area.
Recommendations to industry: Mine operators should review their preventative maintenance inspections for electrical cables to prevent shorts and arcing related fires. The review should include:
- inspections for cable and sheathing damage
- lifecycle management (age of replacement) for cables.

Dangerous incident | SInNot 2018/00031
Summary: While tramming in the decline, a haul truck operator noticed a flame coming from the engine bay. The operator immediately shut the machine down and activated the fire suppression system, which extinguished the fire. Upon investigation, it appears a steel fuel line had been rubbing on a structure that had caused a failure of the line.
Recommendations to industry: Mine operators should review their preventative maintenance inspections for fuel lines. The review should include:
- inspections for rubbing and mechanical wear of fuel lines
- lifecycle management (age of replacement) for fuel lines and hydraulic hoses
- mechanical supports are adequate to prevent rubbing of fuel lines.
Dangerous incident | SInNot 2018/00030
Summary: An articulated dump truck park brake failed to hold a truck when it was stopped, about to tip a load. The loaded truck rolled forward about 50 m before striking an earth berm. The cab of the truck remained upright but the body overturned. The operator reported that the truck lost all steering and braking while rolling forward. No one was injured.
Recommendations to industry: Mine operators should ensure defect reporting and pre-start inspections are being used effectively to maintain safe operating plant.
Safety critical systems such as braking and steering systems should be inspected, maintained and tested in accordance with the manufacturers recommendations.
Dangerous incident | SInNot 2018/00029
Summary: After parking a utility vehicle in the lower quarry bench, an operator of a 40 tonne articulated haul truck parked about 1.5 metres from the back of the utility. The operator exited the haul truck and walked to another area of the quarry. When a leading-hand worker was obtaining something from the front of the utility vehicle, the haul truck rolled forward and rested against the rear tailgate of the utility causing minor damage to the tailgate. No injuries occurred.
Recommendations to industry: Mine operators should review park-up procedures with operators for specific plant with operators. Safety critical systems such as braking and steering systems should be inspected, maintained and tested in accordance with the manufacturer’s recommendations.
