Personnel lifting system fatality

We have learned of a fatality when a worker fell from a full body harness boatswain’s chair when ascending on a hoisting system. The initial information from the investigation team indicates that the individual fell when he became detached from the self-locked grip latch hook, similar to that depicted below. The latch on the hook depicted on the right opens outward.

The company involved has implemented a survey of all personnel hoisting and fall arrest systems seeking:

  • verification that all hook components are designed and manufactured and certified for lifting personnel;
  • where such hooks are used, these should be self-locking and self-closing with an inward moving latch.

Examples of such hooks are shown below.
