## Narrative

A screen panel was being replaced in a triple-deck screen by two mechanics.  One mechanic was working inside the screen loosening the fasteners with a battery impact and ratchet wrench.  While ratcheting, the mechanic felt and heard a pop in his right shoulder.  A medical evaluation revealed a strained/sprained tendon, and the mechanic was placed on restricted duty for healing.
