Two riggers were helping a mobile crane operator unload steel. One of the riggers paused to talk with a supervisor. Unfortunately, the rigger was standing inside the swing radius created by the movement of the counterweight. Shortly after the discussion ended, the crane swung around and fatally crushed the rigger.
