Incident on May 27, 2009: Employees foot is fractured when run over by excavator

On May 27, 2009, a crew consisting of an employee, a Hauling Truck Operator, a M ini Excavator Operator and Foreman, and two other laborers were working on Holla day Avenue. The pipes had already been installed and the trench backfilled. The work involved removing additional 10 inches of dirt to provide the necessary dep th for resurfacing the street. The dirt was being removed by a CAT 304 CR Mini E xcavator moving in backward direction and placing the dirt into a 10-wheeler tru ck which was moving parallel to the Excavator, approximately 5 feet apart. At ap proximately 1:00 p.m., the job at that location was almost completed. The Excava tor Operator signaled the employee to stop. The employee then stepped out of his truck and walked toward the excavator to talk to the foreman; however, he walke d in the path of the Excavator at the time. The Excavator operator resumed his o peration. The employee tried to run away, but he slipped and fell and his left f oot was trapped under the rubber track of the excavator, fracturing three metata rsal bones on his left foot. The foreman transported the employee to San Francis co General Hospital, where he was hospitalized for two days. The employee had su rgery on his left foot two weeks later.
