At 8:10 a.m. on April 17, 2019, an employee was working as a laborer for a firm that mined construction sand and gravel. He was removing a piece of steel from a model number 1654 Kolberg-Pioneer, Inc. jaw crusher, with serial number 401354. The jaw crusher was powered through an unguarded power transmission belt. The b elt was a V-belt, about 76 millimeters (3 inches) wide. The unguarded belt was l ocated approximately 2.9 meters (9 feet, 7 inches) above the ground level. The j aw crusher was located outside east of the break/office trailer on the site, in an approximately 6.5 hectare (16 acre) lot. The weather was cloudy and dry. The employee was climbing on the outside of the jaw crusher to remove the jam. The w ork crew was trained to use locks to control hazardous energy while removing tra mp metal from the jaw crusher and while performing service and routine maintenan ce on it. The training, however, was not specific to the machine. Employees were not aware of a counterweight on the flywheel. The employee reached over or betw een the unguarded power transmission belt. At that time, the crusher's flywheel rotated due to the counterweight. The employee's left ring finger was caught bet ween the belt and the flywheel. It was amputated to the first knuckle. The emplo yee was hospitalized.
