## Narrative

Employee was tightening a bolt on small vibrator mounted on the gypsum hopper. He used two adjustable wrenches to tighten the bolt, one on the top and one on the bottom to prevent the bolt from moving while tightening. He used both hands to push on the bottom wrench when it slipped off. This caused his hand to jerk forward striking metal hopper with top of hand.
