An employee was performing an inspection of a bridge crane while working from a 19-foot scissor lift. The employee was going to use a pendant to move the crane to access a different portion of the crane for visual inspection. The scissor lift guard rails were below the girder of the crane to avoid contact. The tow arm for the crane collectors contacted the guardrail of the scissor lift and caused it to tip over. The employee stayed inside the scissor lift basket as he fell to the floor. The employee sustained fractures to the right arm and hip.
