Abstract: At 7:30 a.m. on November 1, 2021, an employee was delivering products to customers and had arrived overnight and was waiting at the dock. The customer arrived and knocked on the sleeper cab indicating he was ready to receive the load. The employee drove the truck and trailer forward approximately 15 feet so that the trailer doors could be opened. The customer was opening the passenger side door while the driver was opening the driver's side door simultaneously. When the door opened, it swung out forcefully and struck the employee on the forehead. The employee was knocked unconscious, fell backwards, and struck the back of his head on the asphalt. Three boilers, each weighing 222 pounds each fell out of the trailer but did not strike the employee. The boilers had tipped in transit and were likely pressing up against the trailer door which caused the door to forcefully open. The customer called for emergency services and began first aid and CPR on the employee. Emergency response personnel arrived and transported the employee to a local area hospital, where he died one month later.
