This report concerns the death of a 20 year old male truck driver and a 70 year old company president who were electrocuted when the boom of a truck mounted crane contacted an overhead powerline. The employer was a concrete products company that had been in business for about 11 years, employing 14 workers, three of whom were truck drivers. The truck driver who died had been with the company for 8 months. The driver was attempting to unload concrete blocks at a residential construction site. The truck was parked at an angle on a steep slope. Two other men, one the president of the company, watched as the driver used a hand held remote control unit. The tip of the crane boom contacted one of the conductors of the 7,200 volt overhead line, completing a path to ground through the truck, the remote control unit and the driver. The driver fell backward in flames. The company president, running to help instantly, apparently came into contact with the truck as well and was pronounced dead at the scene. The driver died from third degree electrical burns over 98% of his body. It is recommended that employers ensure that workers comply with standards for safe use of cranes near overhead powerlines, that alternative work procedures be evaluated to address site specific hazards, and that employers consider retrofitting cranes with electrically isolated control systems.
