Abstract: At 2:50 p.m. on March 9, 2020, an employee working as a machine operator for a plumbing and heating equipment supplier removed a doubled stacked pan from Station #3, the Hold Punch Station. The employee then handed one of the pans to a coworker to place onto Station #4, the Beading Station. The employee placed the other pan on Station #3. The coworker hit the machine reset button causing the hold punch machine to cycle while the employee was lining up the pan on Station #3. The employee caught his left thumb between the punch hole die and pan. The employee amputated his thumb tip and received medical treatment without hospitalization.
