Three team members were doing repair work on the bullnose dryer to repair a broken chain on the transfer system. A team member was located on each end of the dryer, with a third team member assisting. They were about 15 to 20 feet apart, trying to get the chain back in place. The team members had completed the proper lock-out/tag-out procedure on the equipment. The injured employee noticed the chain was twisted in the sprocket, so he asked them by radio to stop pulling the chain. While he was unjamming the chain in the sprocket, the team member on the other side pulled the chain, which pulled the injured employee's finger into the pinch point between the sprocket and chain. He suffered an exposure facture of the first phalange of the right index finger.
