High potential incident | SinNot 2018/01095
Summary: During a routine service on a load haul dump vehicle, the machine failed to shut down on low scrubber water. An investigation found the safety circuit had been intentionally bypassed.
Recommendations to industry: Multiple incidents have occurred recently across different mines in which bypassed safety circuits have been identified. Mines should have a process in place to appropriately manage bridging and forcing of safety circuits.
Workers need to be made aware of the hazards and potential consequences of unauthorised bridging.
