At about 9:45 a.m. on March 10, 2025, an employee was using a 5-ton overhead crane to move a right-hand check fixture, weighing 5,150 pounds, in a coordinate-measuring machine lab. As the crane lifted the fixture, the metal sling securing the fixture slipped over the employee's left thumb. The thumb was crushed between the metal slip and fixture, and the last joint was amputated.
