Abstract: At 5:50 p.m. on January 29, 2020, an employee helped move a large electrical panel into place using a winch, tow strap, and plastic furniture moving strips. This panel was part of a control room that was being set up in a portable type trailer. While being pulled by the winch, the panel turned and went over a floor opening that was not covered, then the panel tipped over. The employee moved from the back end of the panel and attempted to prevent the panel from hitting the wall. The employee's head got caught between the panel and the wall of the trailer. The employee sustained a hinge fracture at the base of the skull from the impact of a falling panel and the employee's head caught between the panel and wall. The employee was killed by this incident.
