EE WENT INTO STORAGE TRAILER TO GET WIRE CLIPS TO FIX BROKEN HEADLIGHT ON ROCK TRUCK THAT HE WAS DRIVING. WHEN HE REACHED INTO THE METAL BOX THAT WAS UP ON A SHELF TO GET THE CLIP, HE DROPPED THE BOX THAT ALSO CONTAINED A TEST LIGHT. THE BOX WAS HEAVY, BENDING HIS WRIST & THUMB BACK & THE TEST LIGHT PUNCTURED HIS RIGHT HAND BETWEEN THE THUMB & INDEX FINGER.
