Our member took the following actions:

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.
