A surface mine’s safety and health management system must provide for the following safety features for an operator-attended dredge at the mine—
(a) an alarm system to warn the operator when the minimum freeboard for the dredge is breached;
(b) a watertight door or cover on each hatch or opening on a hull that is essential for floating the dredge;
(c) barriers and handrails fitted to or around the dredge to minimise the risk of a person falling overboard.
