Dangerous Incident: shotcrete rig

October 19, 2017 Tara

Summary: An operator using a shotcrete rig was preparing the machine for a maintenance task to repair a fault on the nozzle on the boom. While operating the remote control, a spring return to centre control overshot resulting in the boom moving unexpectedly and the boom / nozzle hit the side of the operator’s head. The operator received treatment in hospital for head injuries.
Recommendations to industry: All mine operators should review procedures for operating and moving machinery to ensure that no-go zones are identified and appropriate for the activities that may be required to be undertaken, including maintenance activities. The risk of injury to an operator from being in the line of fire as a result of an unplanned movement must be considered. The hierarchy of controls must be used to control the hazard.
