## Narrative

Employee was struck in the right elbow by a piece of the carbide steel while standing 4 to 5 feet from the drill rig. The crew were attempting to tighten the casing hammer with the rig's breakout wrench, when a tooth from the jaw broke off and flew the 4 to 5 feet and passed through their long sleeve shirt and entered their inner right elbow, causing a small puncture wound.
