Abstract: At approximately 8:15 a.m. on February 3, 2007, Employee #1 and a coworker (helper) were preparing the seismic drilling rig and water buggy for drilling the first hole of the day. Employee #1 had the rotary on the drilling rig running while he was preparing it for operation. The rotary, with no drill bit connected, was protruding approximately 2 feet horizontally from the rear of the drilling rig and was approximately 5 feet above the ground. The helper was on top of the water buggy and was not watching him. Evidently, during the preparation process, Employee #1 reached toward the rotating rotary and the right sleeve of his jacket was caught by the protruding u-bolt, resulting in his body being entangled on and around the rotary. Employee #1 sustained multiple fractures and blunt force trauma injuries, and was killed.
