Abstract
A pump operator/truck driver was electrocuted when the boom on the concrete pump he was operating contacted a 7600 volt power line. The man worked for a family owned and operated business which was involved in the construction of concrete footers and foundations for light construction. The truck in use by the driver that day was 28 feet long, and had a concrete pump mounted to the bed. A four inch steel reinforced rubber hose was mounted on the boom. The back section of the boom could extent 24 feet and the entire boom could extend 72 feet upwards or forwards. The victim lowered the outriggers on the truck and rotated the pump perpendicular to the bed of the truck after parking the vehicle at the job site. He then elevated the boom and rubber hose to reach the foundation that was to be poured. Apparently the victim was using the pendant controller with a 50 foot cable to elevate the boom while standing on the passenger side of the truck about 8 feet away from the rear of the vehicle. The pendant controller was supposed to be electrically insulated from the pump. The rubber hose mounted on the boom contacted the overhead power line, 33 feet above ground. The cause of death was listed as accidental electrocution. Recommendations arising from this accident included enforcement of existing regulations concerning crane operations in the vicinity of overhead power lines, electrically insulating all boomed vehicles able to contact overhead power lines, and emphasizing safety concerns to all employees.
