Safety alert 03/2011 - Elevating work platform fatal accident
Two people were carrying out maintenance work from an elevating work platform. Both had completed the required training and held the appropriate high risk work licence.
The elevating work platform was being operated on a flat grassed area and the boom of the elevating work platform was extended to approximately 20 meters. While crossing the grassed area, the wheel of the elevating work platform travelled over a concealed septic tank. The concrete lid of the tank collapsed, causing the elevating work platform to abruptly lean to one side. The movement caused the telescopic boom to flex and the operator and co-worker fell out of the basket.
Both men were wearing harnesses at the time of the incident, however it is not clear if the operator had the harness connected to the anchor point located in the basket. The operator was killed and the operator’s co-worker, who was clipped to the basket anchor point, had to be rescued by emergency services.
- The elevated work platform was being operated off-road.
- Underground services had not been identified.
- The operator may not have secured the safety harness to an anchor point.
- Consultation and planning of the proposed work must occur with all people involved in the work.
