Employee (EE) was delivering 16' jumbo steel to the 3520 ORD9 using an Integrated Tool Carrier (IT). Once parked, EE offloaded two pieces of steel. While lifting both pieces of steel under their right shoulder, EE began walking forward. As the steel came off the IT, the imbalanced weight caused EE to fall to ground. As EE was drug to the ground, pain was felt in the right ankle.
