GRM was in area 345 working on #2 secondary cooler when EE attempted to use a wedge & pry bar to get the cooler off the studs. When cooler came free, it lifted slightly and upon coming back down on the studs it smashed right index finger. Brought to local ER afternoon of 12/20/15 & was given prescription meds, then seen by ortho specialist on 12/21/15. Had surgery on 12/22/15.
