Struck By Hook - Fatality (KV 105)


What Happened?

At 11:48 p.m. on July 28, 2017, an employee was moving the crane up to get the alloy steel chain sling out of the way when one of the hooks on one of the legs caught on a low platform edge. After tension on the leg had tilted the hook, it slipped off the edge of the platform and sprung up into the employees face. The employee received severe facial injuries for which he was hospitalized.

Contributing Factors

Having a spotter in place would have alerted the operator that the hook was caught on the low platform edge.

What Can We Learn?


If the crane operator would have used Questioning Attitude, he could have identified the error likely situation that the lower platform presented. 

A Peer Check would have had a co-worker check to see that the actions taken were correct through verbal confirmation.


The employee was certified in the crane hoisting operation and was comfortable in the daily operations of it. This lead to the trap of Overconfidence.
