What happened?
An articulated dump truck (ADT) operator fell asleep while travelling to the hard rock dump area to offload.
He drove into the safety berm separating the two haul roads, causing the ADT bucket to overturn on its side.
The operator was not injured. The ADT and berm were damaged.
The site was cleared, and the incident was reported as a ‘minor operational incident’ with a low potential to be investigated by the contractor’s management team.
After a photo emerged, it became clear it was a very serious incident and a full investigation was launched.
