The injured employee was using a rope to pull a 3-inch hose to the top of a railcar manway so the railcar could be loaded. He was positioned within the handrail/fall protection system on top of the railcar. Another employee was positioned at ground level and was manually lifting/guiding the hose as it was pulled by the injured employee. The injured employee swung his left arm toward the rope to grab it and his left ring finger struck against the railcar's metal handrail/fall protection. The employee was hospitalized for a dislocated finger.
