An employee was carrying a couch up the ramp of a moving truck with his partner. The employee was moving forward up the ramp, and his partner was moving backward up the ramp. The partner had reached the top of the ramp and was inside the truck while the employee was approaching the top of the ramp when a sudden gust of wind hit the employee and the couch. The employee fell forward and to the right, landing on his ribs at the top of the ramp. The employee suffered a fractured rib and a laceration to his liver that required hospitalization.
