BRIEF DESCRIPTION OF ACCIDENT At the time of the accident, two 18-foot, elevator bales weighing 2,600 pounds each were being lifted onto the rig floor using the air hoist. A braided wire rope sling consisting of a hook and eye was run through the eye of the bales to lift them onto the floor. As the bales were lowered to the rig floor, two employees maneuvered them into position using their hands and bodies. The bales struck the rig floor, causing the cable sling to come off resulting in the bales falling to the floor striking two employees, fatally injuring one.
