A truck operator parked and checked that the truck was fundamentally stable. The operator then climbed down from the truck and the truck started to roll forward. The operator climbed back up the ladder and entered the cabin where the operator used the foot brake to stop the truck. The operator then moved the truck to another, flatter location before reporting the incident.
Recommendations to industry: Mine operators should:
- review ‘park-up’ procedures in relation to what is considered ‘fundamentally stable’. This should also include ensuring the machine’s park brake is on
- retrain mobile plant operators on parking ‘fundamentally stable’
- conduct periodic site audits on site park-up procedures.
Where possible, consideration should be given to means to automatically apply the park brake when the operator leaves the control position.
