## Narrative

Employee had finished drilling a hole and had inserted a tube of resin and a bolt into the hole. As EE was pushing the bolt up to set it, the hinge pin for the drill mast fell out allowing the mast to lower and tilt to one side. The drill mast contacted a drill steel in the steel tray and flipped it up and struck the EE in the left ear, requiring stitches.
