Does your lifejacket's operating head moulding look like this one?

Owners of gas-inflated lifejackets are being advised to check the device’s operating head moulding.

Manufacturers United Moulders, who make the Mark 3 Automatic Operating Head used on some lifejackets, have warned there could be a danger of gas releasing from the lifejacket while inflated.

The problem can be caused over time through repeated over-tightening of the CO2 gas cylinder.

The safety warning relates to any Barbour, Cosalt, Crewsaver, Douglas Gill, Fox, Leeda, Musto or Marlin brand automatic lifejacket purchased before 1998 and which is fitted with an operating head as pictured.

A spokesman said: “The remedy is simple and does not require the return of the lifejacket to the manufacturer.”

If the operating head on your lifejacket is identical to that in the photo, go to the page on the Crewsaver website www.crewsaver.co.uk/mk3 for further instructions. Alternatively call Crewsaver. Tel: 023 9252 8621.
