What happened?

“Recently a fisherman and a workboat crewman died when the inflatable lifejackets they were wearing failed to inflate. We suspect that the gas cylinders may have worked loose since the lifejackets were last inspected.

The following key learning points have been noted:

  • Owners of inflatable lifejackets should have them serviced and inspected in accordance with the manufactures’ instruction.
  • Owners should include the service and maintenance of inflatable lifejackets within their safety management system.
  • Users of inflatable lifejackets should be instructed in their use.
  • Owners should maintain a record of serving, inspection and the training of users of inflatable lifejackets; . Users of inflatable lifejackets should inspect them before putting them on. Inspection should include:
    • Inspection of straps, buckles and outer covers.
    • Inspection of Safety harness, its stitching an buckles.
    • Inspection of the inflatable lung for abrasion damage.
