Abstract: At 6:00 a.m. on September 7, 2017, an employee was giving direction to another employee who was turning off the site lamps used for overnight work. As the employee turned to walk away after providing the directions to employee at the field lights, he was struck by a John Deere 850K WLT Bulldozer that was backing up. The roughly 45,000 pound bulldozer backed up over the employee crushing numerous bones in the body. Backup alarms were audible and the operator turned around to view in the direction of travel, but did not observe the employee who may have been standing in a blind spot. The employee received fractures to face, orbital fractures, numerous fractures to the legs and hips, and inevitably death.
