Dangerous incident | SInNot 2018/00013
Summary: A charge-up rig was driving in the decline when the operator noticed flames possibly coming from the central articulation area. The fire was immediately extinguished and the plant isolated. It appears the fire may have been caused by a burst hydraulic hose spraying oil on the engine exhaust.
Recommendations to industry: Mine operators are reminded to review:
- mechanical protection of fluid conductors (hoses) of fuels or oils
- rubbing and abrasion of cables and fluid conductors
- clamps and fixings of cables and fluid conductors
- segregation and separation of mechanical services and electric cables and devices
- location of and value of maximum surface temperature
- location of fire suppression activation points
- compliance with Australian Standard 5062:2016 – Fire protection for mobile and transportable equipment.
Dangerous incident | SInNot 2018/00011
Summary: An underground mono pump stopped operating and upon inspection the electrician noticed smoke and a possible fire coming from the pulley belts that drive the pump. The electrician used an extinguisher to eliminate any fire, isolated the pump and notified the shift supervisor.
Recommendations to industry: Mine operators should review maintenance procedures including adjustments lifecycle management of drive belts in accordance with manufacturers recommendations on fixed plant installations.
Dangerous incident | SInNot 2018/00010
Summary: A haul truck operator lost traction on an over-watered haul road ramp (no dry line). The driver stayed in his lane despite spinning the truck 180 degrees after hitting the retard pedal.
Recommendations to industry: Mine operators should review how roads, especially ramps, are watered and how often they are inspected for “dry lines”. They should also review how statutory officials communicate and correct potential hazards.
Serious injury | SInNot 2017/02097
Summary: An electrician was driving a ute (light vehicle) around a right-hand bend when he lost control. The ute spun around and rolled onto the driver's side. The driver was not injured. He was drug and alcohol tested and checked for dehydration. All results were negative.
Recommendations to industry: Mine operators should review how compliance with road rules is assessed, especially leading into holidays or end of rosters.
Dangerous incident | SInNot 2017/02076
Summary: While welding a cleat to the port side of the dredge approximately 100mm above the water, the wind created waves that splashed up onto the work area. This resulted in the person welding receiving an electric shock.
Recommendations to industry: Mine operators should review how employees and contractors assess the change in risk when there is a change in working conditions.
Dangerous incident | SInNot 2017/02075
Summary: A worker was welding a pipe to the outside of a sump. A fire occurred inside the sump with flames passing up through floor grating above the sump to within 1 m of the second floor. A fire watchman quickly extinguished the fire using a water hose from the first floor.
Recommendations to industry: Mine operators should review how potentially flammable materials, including glues are assessed. They should also review “No Go Zones” around and above such hot work areas.
