In respond to this incident the Regulator commented: Mines should ensure all employees working around equipment with high-pressure hydraulic systems are fully aware of the dangers of fluid injections entering the body and the damage they can cause.

Cut out distances need to be reviewed and changed in different geological conditions in order to minimise the accumulation of stone in the working area. Excessive build-up of material around hoses should be avoided, inspected and cleaned prior to operating bolting rigs. Operators need to maintain situational awareness in relation to hoses contacting sharp edges.
