Abstract: On October 27, 2003, Employee #1, a temporary help employee, was driving an articulating dump truck down an eight degree slope when he lost control while making a left turn and the truck overturned. As the articulating dump truck overturned, Employee #1 was ejected from the truck's cab and suffered serious injury requiring hospitalization. Employee #1 suffered fractured ribs, a punctured lung, and a fractured scapula. Employee #1 had previous experience driving an articulating dump truck at another location and the employer had given Employee #1 a practical test to determine competence, which Employee #1 passed. Employee #1 was not trained as to the unique hazards of his new job assignment at this location.
