Employees were moving an electrical box weighing approximately 200 pounds from a forklift onto a pallet. The electrical box was on the forks of the forklift and the forks were tilted down. The forklift pulled back to have the electrical box slide off the forks. On the other end, employees were bracing the electrical box from tipping over. The box then fell forward, the injured employee slipped while evading the box, the box hit his lower leg and torso, and he fell fell backward. The employee was hospitalized with a fractured T12 vertebra.
