Incident date: 2020-05-12
NAICS industry code: 332612

An employee was approaching the exit end of an automated and fully enclosed shot machine. A spring that was discharging jammed between the discharge pusher and the discharge transfer plate. The spring unjammed suddenly. Due to the excess force created between the discharge pusher and the discharge transfer plate, the spring shot out of the machine to the stop plate, a distance of approximately 8 feet. At that exact moment, the employee's hand was near the discharge table and the spring struck the employee's right arm, catching it between the spring and the stop plate. The employee suffered broken bones to the lower right arm (wrist area) as well as severed tendons and nerves.
