## Narrative

EE was helping two other employees tension cable bolts using a hydraulic tensioner. The cable was bent and had bound inside the tensioner. A 4 lb hammer was being used to the knock down on the top of the tensioner as EE pulled downward on the tensioner handles. On the 3rd or 4th hit, the hammer deflected off and struck the employees finger.
