## Narrative

Per employee ""I was assisting with opening and closing the clamp as needed. The jaws of the clamp seem to have been worn resulting in not enough grip on the drill pipe. This caused the pipe to slip into the hole, hitting the tip of my left thumb against the clamp, resulting in an injury.""
