Two employees were installing aluminum siding on a farmhouse when it became
necessary to remove a 36-foot high metal pole CB antenna. One employee stood
on a metal pick board between two ladders and unfastened the antenna at the top
of the house. The other employee, who was standing on the ground, took the
antenna to lay it down in the yard. The antenna made electrical contact with a
7200-volt power transmission line 30 feet 10 inches from the house and 23 feet 9
inches above the ground. The employee handling the antenna received a fatal
shock and the other employee a minor shock. What precautions might have
prevented this accident?
