hree employees of Robert Forepaugh Inc., a Bensalem, Pa.-based demolition contractor, were killed Aug. 21 when a wheeled crane’s boom became entangled in a 7,200-volt power line while demolishing a cement batch plant at a JDM Materials cement plant in Telford, Pa. The incident occurred when Robert Forepaugh, 68, backed the crane up an incline under the energized power line and the boom hit the wires. Forepaugh was thrown or fell from the truck cab. Two other workers, George H. Frederick, 41, and Daniel G. Evans, 29, went to his aid and were electrocuted when one came in contact with the crane. "One witness said they didn’t realize the crane was energized and apparently thought Forepaugh had suffered a heart attack," says Douglas Bickel, Telford police chief. Forepaugh was in the process of cutting and pulling down the batch plant conveyor when the incident occurred. "The power lines were quite a distance from where they were working," says Bickel. The federal Occupational Safety and Health Administration is investigating the incident, according to an OSHA spokeswoman. But it is unclear what actions can be taken as it appears that the three victims were the only employees of the company.
