An employee was cleaning coal build-up inside pulverizers that were 10 feet 3 inches wide and contained three stationary rollers. After dislodging a piece of coal, the employee exited the pulverizers when the converging floor moved and their left leg was caught between one of the three rollers. The employee suffered injuries including a laceration to the lower left thigh and multiple fractures to the lower left leg. The motor to the converging floor was not in place at the time of the incident.
