On July 7, 2012, A choker setter was assisting another employee by dragging the yarder cables toward a felled tree. This tree had already been wrapped with a choker and was ready to be pulled out to the landing area.
The two workers were working from opposite ends and the employee located on top of the hill was pulling the cable and hook towards the felled tree. The eye of the cable broke from the yarder.
As a result, the hook the employee was holding came flying loose. It swung down the hill towards employee #2 and struck him in the chest. He was hospitalized for five days but survived.
Proper machine inspection before the start of shift could have helped identify the faulty cable that broke free from the yarder.
What Can We Learn?

Procedures should be in place that requires them to inspect all equipment before the work begins.
The employees fell into the Overconfidence trap by assuming their machines and cables were in good working conditions before performing their work.
