EE was lifting a piece of metal plate flooring, approx 4'x5', weighing approx 100# to access work area. As EE slid the plate, EE lost grip & it dropped onto the fingers of EE's right hand. EE snatched EE's hand out from under the metal plate which caused the skin of EE's right forefinger to tear back, requiring 4 stitches. EE was not wearing any gloves at the time.
