Abstract: At 3:10 p.m. on November 19, 2019, an employee working as a truck driver for a farm products warehousing company was loading feed into his truck. The employee had parked his truck under the overhead auger spout in preparation to load feed. He attempted to run the auger, but it was jammed and wouldn't operate. The employee and a coworker climbed on top of the truck and removed the guard from the belt and pully mechanism on top of the auger. The employee was using a 36-inch pipe wrench to turn the shaft in order to unjam the auger. As the employee was using the wrench on the shaft in an attempt to turn it the wrench slipped. The employee lost his balance and fell approximately eleven feet from the top of the truck to the ground below. Fall protection was not used. The employee sustained broken bones in his left hip, legs and arms and was hospitalized.
