Abstract: At 07:54 a.m. on August 06, 2019, an employee, a supervisor, was changing out a conveyor belt on a long conveyor. The employee was working with three coworkers to replace the conveyor belt. The employee was working off the side where the railing access was located. The new belt was sitting on a support structure approximately 13 feet off the ground. The method used to replace the old belt and install the new belt involved having a round bar run through the center of the new belt which sat atop a support structure. The support structure had arms on both sides of the conveyor system. The employee had moved to free up the new conveyor belt that was to be replaced by jumping across the conveyor to the side without railings. A coworker, a crane operator, was asked by the employee to pickup the roll which moved, swinging out, knocking the employee 12 to 15 feet to the ground. The employee was hospitalized to treat a fractured pelvis.
