Summary: A collision occurred between a slow-moving haul truck that was passing a stationary grader between the right-hand side of both machines. Seeing the collision about to occur, the grader operator tried to make radio contact with the truck driver, who was on a different channel. No injuries were reported.
Recommendations to industry: Effective communications protocols and procedures should be in place to ensure that positive communication between all operators is be achieved, and the proper use by equipment operators of these protocols is monitored on a continuous basis. Recently, there numerous incidents have been reported to the regulator where a lack of positive communication between operators has occurred. Monitor and assess compliance with site positive communication protocols.
Refer to Safety Bulletin 18-06 Lack of positive communications.
