Summary
A mini transponder fell 20 m to a ship’s deck after a faulty crane end stop allowed excessive hoisting, narrowly missing two crew members. The flash describes lifting-area restrictions, toolbox discussions, improved end-stop switches, a formal attachment procedure and a purpose-designed bracket preventing contact with the end-stop block.
