## Narrative

He was putting a 4 foot bolt up. He put the bolt in the hole and had to bend the bolt back straight, once he did he bumped his rotation and the bolt caught his hand and spun it around the bolt. He thinks he just strained some ligaments to his thumb. He returned to work the next shift, but is doing restricted work.
