EE and partner were setting up a jig to assist in fit up of the ring to the duct work. EE was holding the piece low to assist in getting the jig welded to the duct. EE's partner stuck EE's weld rod to tack up the piece and rod got stuck. When EE went to remove the rod, the piece fell and landed on EE's pinky fingertip which caused a laceration. EE did have gloves on.
