On November 4, 2021, at approximately 10:30 AM, an employee connected a chain to a flat railroad car and transfer puller that pulls kiln cars out of a dryer. As the transfer car was pulling the drying car, the chain came loose and the employee reached to grab the moving chain. The chain snagged and became tight, and the employee's thumb was caught between the chain links. The employee was hospitalized for a deep laceration to his thumb that required surgery.
