## Narrative

The employee was beating the cone at the bottom of tank #6 to loosen mud that had accumulated at the bottom of the tank.  The head of the hammer glanced off the side of the tank.  Because of this, he hit his left hand on the guard rail of the catwalk.  This caused severe pain, numbness, and swelling in his left hand.
