## Narrative

Injured was removing material from a stopped up air pump. He had turned the pump off and stuck his hand down inside of the pump; as he was doing this his knee struck the cut off valve for the air and turned the air on to the pump. This caused the pump piston to move and strike his hand and pinch it between the pump housing and the piston.
