Abstract: At approximately 2:30 p.m. on October 17, 2008, Employee #1 and a coworker, both tire fitters, drove to the site of an earth moving machine. Their task was to change three of twelve tires on the earth mover. The tires measured approximately 14 in. by 24 in. and stood approximately 52-in. tall. The coworker operated the vehicle, which consisted of a large commercial tractor attached to two earth moving scrapers. Employee #1 was changing out the tires. A store manager arrived to assist with the operation at approximately 6:00 pm. He and Employee #1 finished the task on one of the tires. Employee #1 was laying on the ground when the machine moved backward. It ran over Employee #1's left hip and stomach. Employee #1 fractured his left hip and sustained internal injuries. He was hospitalized.
