An employee was working upstairs in the bourbon barrel finishing department. Barrels are transported from a lower floor up an incline to a chain conveyor in the bourbon barrel finish department. When barrel supply was interrupted, the employee placed his hand on the chain conveyor to lean over and look down the line. The line started and his fingertip, extending down against the chain, was caught in a chain and sprocket. The incident resulted in medical amputation of the fingertip.
