Fractures

An employee and a coworker were adjusting the stops on the second plate of an 825-ton press. They needed to bring the second plate up for adjustment. The coworker was operating the controls to adjust the height of the second plate and proceeded to turn off the exhaust. The second plate raised while the employee working inside the press had his arm resting on the trip rod. When the second plate raised, it pinned the employee's right forearm between the trip rod and main ejection nut, causing a compound fracture.
