An employee was painting from a mobile scaffold that was 6 feet by 3 feet and three frames high. The scaffold had railings on three sides and no railings at the wall side. The employee was cleaning his painting trail when other employees moved the scaffold about 2 to 3 feet from the wall. At that point, the employee lost his balance and fell about 16 feet to the concrete floor, fracturing both ankles. He was hospitalized and had surgery.
