At about 2:50 p.m. on November 7, 2022, an employee was guiding a backhoe while another person operated it. The operator lost eye contact with the employee and someone yelled at him to stop the backhoe. At the same time, the employee tried to get away from the back of the backhoe, leaned on a handrail around the underground tank they were building, and fell through the rail to the bottom of the tank about 10 feet below. The employee suffered injuries to the spine and left hand.
