Abstract: At 01:15 p.m. on February 23, 2022, an employee was removing a port cover at the point of a rotating valve which produces a suction within a metal tube to move the animal food product throughout the mill handling unit. The employee was trying to identify the source of a squeaking sound within the tube. The employee inserted his hand up into the pipe and then down into the spinning valve as he pulled his hand out. Due to the employee opening the port cover while the machine was in operation and pulling his hand back out of the tube, past the spinning valve, the employee's fingers were caught by the valve. The employee was admitted and treated at the hospital for an amputation to the right index and middle fingers.
