Abstract: Employee #1 was in the process of setting chokers off the butt rigging from a high lead, South Bend logging system. The company was engaged in side hill logging. Employee #1 attempted to set a choker on a 36 inch diameter by 27 foot long Douglas fir log on a hill with a grade of 30 to 32 degrees. The log was unstable in that the butt end was resting on a tree stump 3 feet above the ground, and the other end was resting on two other logs. Employee #1 was on the downhill side of the log when it slipped off the tree stump, rolling on top of him and pinning him against another log approximately 10 feet down the hill. Employee #1 was killed almost instantly.
