Abstract: On August 4, 2020, an employee was working for a chain of discount variety stores that sold inexpensive items. He was working as a maintenance technician in a warehouse or distribution center. He and two coworkers, also maintenance technicians, were repairing a motorized mobile conveyor belt. The employee was working in an electrical enclosure attached to the infeed end of the conveyor. The store's management indicated that the source of electric power inside the panel had been deenergized. The disconnect switch, though, was not locked out. A coworker discovered the employee in a kneeling position in front of the electrical enclosure. The employee had suffered trauma to the back of his head. He was unresponsive and had blood on the back of his head. Several first responders performed CPR, but all efforts failed. The employee was declared dead at a local hospital.
