Two employees were working in a parked and elevated scissor lift to work on festoon wiring that energized a traversing conveyor system. The conveyor moved and the festoon wiring pushed on the side of the scissor lift. The employees were not able to lower the scissor lift at that point, and when the conveyor moved again, the wiring pushed the scissor lift over. One employee suffered a broken arm and hip and that required surgery and hospitalization. The second employee broke his finger and suffered contusions.
