An Insulator technician received a cut to the right hand while preparing an insulating end cap in a satellite fabrication shop. The technician was separating a sheet metal seam on a piece of insulating stock to allow assembly of an end cap. While separating the seam with a pulling motion using an awl, the awl slipped out of the seam, and the technician’s hand came in contact with the sharp edge of the sheet metal, resulting in a laceration on the right hand. The worker was not wearing gloves at the time of the injury. Six sutures were required to close the wound.
Incorrect tool for the task - A cutting wheel in lieu of the awl is the preferred tool for this task.
