Summary
A crew member escaped without injury when a vessel’s propeller shaft began rotating during monthly carbon-brush maintenance beneath the shaft generator. The flash examines absent isolation and permits, inadequate supervision, and failures to communicate a change in vessel operations. Lessons address work authorisation, isolation, coordination and stopping unsafe tasks.
