## Narrative

Employee stated that he had installed a bolt close to the rib and had let the pressure off his canopy to swing his boom over toward the center. The canopy didn't come down, it was hung on the rib so he released his floor jack to swing the boom over, not realizing what could happen. The canopy when he started swinging, free fell and struck him in the head, neck and back.
