Abstract: At 8:00 a.m. on August 23, 2017, an employee head a clicking noise while running a 500-foot long manure belt in Aisle T of the Manure Shed of House D. The clicking noise indicated that the drive needed an adjustment for timing. The employee gripped a drive chain with his left hand while using a pry bar to adjust a tensioner with his right hand. The chain tension shifted and the chain moved in a counter clockwise direction, catching the employee's left hand middle fingers in the chain and sprocket. The employee suffered a partial amputation of his pinky and middle finger as well as lacerations to his left index finger and ring finger. Hospitalization was not required.
