Dangerous incident | IncNot0040901

Coal processing
Summary: A team of fitters were replacing a hydraulic cylinder above a conveyor. A hired elevated work platform (EWP) was required to access the cylinder. The EWP basket was moved into position to allow removal of the old cylinder. After releasing the joystick (while the operator’s foot was still on the deadman switch), the basket moved up approximately 200 millimetres. The safety bar contacted the cylinder support structure, which activated and stopped the EWP.  The fitters were standing beside the cylinder support structure.  No personnel were injured during this incident.
The investigation found the boom control joystick locking collar was not functioning correctly. The locking collar requires the operator to lift the collar before selecting a function to prevent accidental activation. The grub screw that secures the top of the joystick was missing, allowing the mechanism to partly unscrew. As a result, the function could be activated without lifting the locking collar, resulting in an unplanned movement. 
Comments to industry: Mechanical engineering control plans must set out the control measures for the unintended operation of plant. This must include function testing as part of the introduction of plant to site process and pre-use inspections by operators. Refer to:
SB15-04 Collisions of mobile elevated work platforms increase

Dangerous incident | IncNot0040868

Underground coal mine
Summary: A high voltage cable supplying a conveyor starter in an underground coal mine was found to have impact damage. The PVC outer sheath was damaged and the armouring distorted, exposing the internal lead sheath. It was discovered hanging from the roof about one metre from the rib. A duckbill carrying an air track was sitting underneath the cable.
Comments to industry: When developing control measures to manage the risks associated with roads or other vehicle operating areas, the placement of services that may be exposed to risk of damage such as cables and pipelines must be considered. Factors for consideration include: 
  • roadway height and width 
  • height and width of loads that are required to be transported in the roadways, including the effect of bumps and dips with overhanging loads
  • positioning of cables and other services suspended from the roof
  • effect of roadworks that may alter the effective roadway dimensions over time.

Dangerous incident | IncNot0040899

Underground coal mine
Summary: An operator was installing rib support using the continuous miner. The worker was on the same side as the ventilation tubes.  Whilst inserting a rib bolt, the operator's cap-lamp and helmet were sucked into the ventilation duct. Earlier in the day the auxiliary fan speed was increased from 12.5 m3/sec to 19.5 m3/sec to assist dust management due to the continuous miner cutting stone.
Comments to industry: Mine operators should ensure that appropriate control measures are in place to protect operators working near open-ended ventilation tubes. Guarding should be installed on the most inbye tube to prevent objects being sucked into the tube. Operators should use cap-lamp pouches with retaining straps. Mine operators should review their auxiliary fan operational risk assessments (for each type of auxiliary fan in use at each site) to identify and control the risks to health and safety for people working in close proximity to ventilation ducts. Refer to:
SA20-05 Worker sucked into auxiliary fan ventilation tube

Safe use of quick hitches on excavators – Safety alert #398
A worker was seriously injured while performing maintenance work on the bucket of a 30-tonne excavator. The bucket suddenly detached from its quick hitch, swinging about 1.5 metres before it fell to the ground. The worker was knocked over by the bucket, hitting their head on the concrete floor and sustaining a crush injury to their leg.

*While the majority of incidents are reported and recorded within a week of the event, some are notified outside this time period. The incidents in this report therefore have not necessarily occurred in a one week period. All newly recorded incidents, whatever the incident date, are reviewed by the Chief Inspector and senior staff each week and summarised in this report.
