High Potential Near Miss — Vehicle Interaction

A light vehicle entered an active exclusion zone on the Pit 4 haul road while a CAT 793 haul truck was conducting dumping operations. No physical contact was made and no injuries occurred. The LV driver reported not seeing the exclusion zone signage due to dusty conditions and reduced visibility. The designated spotter was not in position at the time of the event.

Critical — Medical Treatment Injury (Fall from Height)

A scaffolder fell approximately 2 metres from scaffolding at Processing Plant Level 3. The worker was wearing a harness but it was not clipped to the anchor point. He landed on the platform below and sustained back pain. The scaffolding had been inspected the previous day and was tagged green.

High — Equipment Failure (Hydraulic Line Rupture)

A high-pressure hydraulic hose on a CAT D10 dozer ruptured during routine blade operations in the workshop test bay. Hydraulic fluid sprayed at approximately 3,000 PSI, narrowly missing the fitter who was conducting a post-maintenance function test. The hose had been replaced 6 weeks prior but the replacement hose was not OEM specification.

Medium — Near Miss (Dropped Object)

A 15kg steel plate fell from the tray of a service vehicle while transiting across the ROM Pad. The plate struck the ground approximately 3 metres from a group of workers conducting ground-level inspections. The plate had been loaded unsecured earlier in the shift and was not identified during the pre-start vehicle inspection.

Critical — Serious Potential Incident (Confined Space Entry)

Two workers entered the primary crusher chamber to clear a blockage without completing the mandatory confined space entry permit. The atmosphere had not been tested, and the confined space attendant was not in position. The workers were discovered by the Shift Supervisor during a routine area inspection. Atmospheric testing conducted after the event revealed oxygen levels at 18.2% — below the safe minimum of 19.5%.

High — Environmental Incident (Tailings Seepage)

Routine monitoring detected elevated seepage levels at Tailings Storage Facility Cell 3, with flow rates exceeding trigger levels by 30%. Investigation identified a section of the drainage blanket that had become blocked with fine sediment, causing localised elevated pore pressures. The condition was identified during a scheduled monitoring round.

Medium — Near Miss (Ground Conditions)

A section of pit wall measuring approximately 12 metres wide and 8 metres high collapsed in Pit 4, Zone B during a shift change period when no personnel or equipment were in the immediate area. The collapse occurred approximately 30 minutes after the area had been vacated for the shift change. Geotechnical prisms in the area had shown 4mm of movement in the preceding 48 hours.

Low — Hazard Report (Fatigue Management)

A worker self-reported fatigue symptoms including difficulty concentrating, slow reaction times, and microsleep episodes during the final 2 hours of a night shift. The worker had completed four consecutive 12-hour night shifts and had reportedly only achieved 4 hours of sleep before the shift due to accommodation noise issues. The worker was stood down safely and transported to accommodation.

High — Chemical Exposure (Reagent Spill)

Approximately 200 litres of sodium cyanide solution spilled from a dosing line rupture in the CIL circuit at the Processing Plant. Two operators in the immediate area were exposed to hydrogen cyanide gas at concentrations of 8ppm — above the 10-minute STEL of 4.7ppm. Both workers self-rescued using emergency escape respirators and were assessed by the site paramedic. No injuries sustained.

Critical — Serious Potential Incident (Explosives Handling)

During explosives loading operations at Pit 2, a shot firer discovered that three detonators had been left in the blast pattern from the previous day's aborted shot. The detonators were live and had been covered by approximately 0.5 metres of stemming material. The area had been traversed by a front-end loader earlier in the shift to clear loose rock. Had the loader tracked over the detonators, detonation was possible.

High — Equipment Failure (Conveyor Belt Fire)

A fire started on the secondary crusher conveyor belt due to a seized idler roller that created excessive friction and heat. The fire was detected by the fixed heat detection system and the belt was automatically stopped. The onsite fire crew extinguished the fire within 12 minutes. Approximately 15 metres of conveyor belt was destroyed. No injuries occurred.

Medium — Near Miss (Pressure/Hydraulics)

A dewatering pump pressure relief valve failed to activate when system pressure exceeded the rated limit during a blockage in the discharge line. Pressure reached 150% of the rated maximum before an operator noticed the gauge reading and performed an emergency shutdown. The pipeline showed visible deformation at two flange joints. No rupture occurred.

High — Near Miss (Vehicle Interaction — Water Cart)

A water cart reversed into the blind spot of a stationary grader on the Pit 4 access ramp. The water cart operator did not conduct a 360-degree walk-around before reversing and was relying solely on mirrors. The grader operator saw the approaching water cart and sounded the horn, causing the water cart to stop approximately 1.5 metres from contact. Both operators were uninjured.

Medium — First Aid Injury (Manual Handling)

A maintenance fitter sustained a lower back strain while manually lifting a 32kg pump impeller during a scheduled pump overhaul. The fitter had bypassed the overhead crane because it was occupied with another task and attempted to lift the component manually to save time. The fitter reported immediate onset of lower back pain and was unable to continue work.

High — Fire/Explosion (Workshop Fire)

A fire broke out in the main workshop when a grinding operation ignited accumulated oil and grease residue on the floor beneath the work area. The fire spread rapidly along the oil contamination trail to nearby waste oil drums. The workshop fire suppression system activated and contained the fire. Workshop personnel evacuated safely within 90 seconds using emergency exits.

Medium — Near Miss (Structural — Berm Failure)

A safety berm on the Pit 2 dump crest failed while a loaded haul truck was tipping. The berm collapsed outward, and approximately 20 cubic metres of material slid down the dump face. The haul truck was positioned correctly behind the berm line and was not affected. The berm had been constructed using soft, unconsolidated material rather than the specified compacted rock fill.

Low — Hazard Report (Electrical — Cable Management)

During a routine electrical inspection, multiple instances of damaged and poorly routed trailing cables were identified at the Power Station switchyard. Three cables had damaged outer sheaths exposing inner insulation, two cables were routed across vehicle access paths without cable crossover protection, and one cable was found to be in contact with a hot water pipe.

High — Near Miss (Vehicle Interaction — Haul Truck Rollback)

A loaded CAT 793 haul truck experienced an uncontrolled rollback of approximately 8 metres on the Pit 4 haul ramp (12% grade) when the operator selected the wrong gear after stopping for a radio communication. The truck rolled backward before the operator applied the service and park brakes, coming to rest approximately 15 metres from a water cart that was ascending the ramp behind it.

Medium — Near Miss (Thermal/Heat Stress)

A process operator collapsed from heat exhaustion while conducting a routine inspection of the SAG mill discharge area. The ambient temperature was 44 degrees Celsius. The operator had been working for 3 hours without a scheduled heat rest break and had consumed less than 500mL of water during that period. Co-workers administered first aid and the operator was transported to the site medical facility. Full recovery was made.

Low — Hazard Report (Wildlife Encounter)

A king brown snake (mulga snake) was found inside the cab of a service vehicle parked overnight at the ROM Pad staging area. The vehicle operator discovered the snake coiled on the floor mat when entering the vehicle for the morning shift. The operator exited the vehicle calmly and alerted the site wildlife handler, who safely relocated the snake. No injuries occurred.

Critical — Serious Potential Incident (LOTO — Crusher Maintenance)

During scheduled maintenance on the primary jaw crusher, a maintenance crew began removing a liner plate while the crusher's hydraulic system was still pressurised. The isolation tag board showed the hydraulic system as isolated, but the physical isolation valve had not been turned. The discrepancy was identified by a second fitter who noticed the hydraulic accumulator pressure gauge still reading 200 bar. Work was stopped immediately.
