On February 1, 2023, an employee and co-workers were performing maintenance on a board stacker by replacing the chain. They removed some slats to help guide the boards and pulled a pin on the coupling to the dual sprocket drive. The weight of the remaining slats then caused the chain to move up on the inside as the slats moved down on the outside. The employee's ring then became caught on the chain, resulting in the amputation of his left ring finger above his first knuckle.
