What happened?

The cook received first aid onboard; the incident was classified as a high potential near miss.

Showing earth fault of the electrical heating element
What was the cause?
- There was a an earth fault in the electric heater element of the bain-marie due to a detached earthing wire.
- There had been no recent testing or maintenance of the galley electrical system.
Additionally it was found that:
- There was no planned maintenance schedule for inspection of galley equipment.
- Onboard Risk Assessment for use of portable and other electrical equipment did not include Portable Appliance Testing (PAT ) of galley electrical equipment.
Actions?
- Thorough inspection for and removal of, any damaged or deteriorated electrical equipment.
- Arranged unscheduled testing of all stationary and portable electrical equipment on board vessels fleetwide.
- Added galley electrical equipment inspection and maintenance to planned maintenance system.
- Updated Onboard Risk Assessment for use of portable and other electrical equipment on board to include equipment in the galley and the mess.
Mains electrical safety may be more easily overlooked in areas such as the galley, the mess, the accommodation and on the bridge. The risks involved in improperly maintained electrical equipment are further illustrated in this news story here from 2014 in which a young person was killed in her home: insulation around a mains extension cable had become worn, and a live wire was exposed, causing her death by electrocution.
