Abstract: On August 2, 2004, Employee #1, a laborer with Tollenaar Holsteins, was loading a wagon with bales of hay. He was driving a tractor that was hitched to an open-sided wagon while a coworker was using a "squeeze" forklift to load bales onto the wagon. After the front of the wagon was loaded, Employee #1 moved the tractor and wagon forward. As the wagon rode over a bump in the floor, the loaded hay bales immediately behind Employee #1 shifted and fell forward, striking him. Employee #1 was hospitalized at UC Davis Medical Center in Sacramento for observation and intravenous pain medication, however he sustained no serious injuries.
