On December 11, 1984, two workers were electrocuted while guiding a steel structure being lifted into place by a 48 foot telescoping boom crane, and a third worker was severely burned. A steel erection company, in business for less than 1 year, was a subcontractor on the construction of a materials storage shed. Two sets of 23,000 kilovolt overhead power lines were in the work area: one was about 5 feet from the steel section being moved, and the other set was about 10 feet from side of the structure. A telescoping boom crane was being used to move an incorrect roof beam and attached support columns. During the process the horizontal beam came into contact with a 23,000 volt power line. Two of the three workers were electrocuted. The third, who only had one hand in contact with the steel section, received serious electrical burns. Several factors contributed to this fatal accident. Apparently there was insufficient safety awareness on the part of the general contractor prior to issuing a subcontract and during steel erection. The electrical lines were neither deenergized, insulated, nor moved away from the construction activity. The incorrect beam was installed. Nonconductive taglines were not used in the task of lowering the steel structure. The subcontractor had no written safety program nor standardized procedures for working around power lines.
