Abstract: On November 8, 2001, Employee #1, a driller's helper, and Employee #2, the drill site supervisor, were using an Ingersoll-Rand TW-4 Waterwell Driller to drill a domestic water well. Employee #2 was acting as a safety observer and directing elevation of the derrick. Employee #1 was raising the derrick using the rear control panel, while relying on hand signals from Employee #2 to maintain safe clearance. Employee #2 gave a "thumbs-up", signaling to elevate the derrick and he then proceeded towards the drill rig. The derrick struck a 21-kilovolt overhead power line and Employee #1 was electrocuted. Employee #2 received an electric shock and sustained serious injuries, for which he was hospitalized. The vertical clearance between the derrick and the overhead line was determined to be 15 ft.
