Abstract: Employees #1 and #2 and a coworker were picking up trash in a residential area. Employees #1 and #2, the trash attendants, were behind a rear-loading trash truck (a Freightliner with a Heil Formula 5000 refuse collection unit). The driver, who was not aware that they were there, backed over them. Employees #1 and #2 were hospitalized for injuries including a broken arm, severe burns on the legs and upper body, abrasions, cuts, and lacerations. Neither the driver nor Employees #1 and #2 were trained in safe backup procedures. As a result, the driver had continued backing up even though he had lost sight of Employees #1 and #2 and did not know their whereabouts.
