The driller sustained severe bruising to his body and back and could have been seriously injured or killed.

1. A risk assessment should be conducted to develop a risk management strategy for all drilling activities that are conducted with the use of high-pressure air or water. Risk assessments should consider controls to prevent high-pressure hoses and associated equipment moving in an uncontrolled manner following a failure in a high-pressure hose or pipe...
