## Narrative

Employee was rib bolting in #1.  EE was bringing the steels out of the rib to add the bolt wrench to finish drilling the hole.  EE put hand near the steels to grab the bottom steel.  The drill pot and steel was in a bind. When the bottom steel came out of the chuck, it sprung towards the bolter mast, pinching EE's left thumb between the steel and the steel guide.
