Notice to all Ship-owners, Ship Operators, Masters and Officers of Ships, Ship Designers, Shipbuilders and Manufacturers of Marine Electrical Equipment. This MGN highlights potential hazards of arc flash associated with high and low voltage electrical equipment onboard vessels.
Key Points:
– The best approach for electrical safety to prevent an arc flash incident is to only perform work on de-energised equipment that has been placed into an electrically safe condition.
– After control measures to reduce the risk of an arc flash have been investigated/ implemented, protective clothing and PPE requirements should be carefully selected.
– One of the major hazards associated with an arc flash is burn injury from the exposure to the thermal energy from an arc flash.
