An employee was stepping down from an elevated platform, that is 30 inches above the floor, onto two stacked pallets that had two pieces of cardboard stacked on top of each other on the surface of the top pallet. The employee placed his right foot on a piece of cardboard that was not aligned with the pallet. His left foot slipped and he fell backwards, hitting his head on the concrete floor. The employee sustained head injuries including hemorrhagic contusions with associated subarachnoid hemorrhage, subdural hematomas, and a fracture of the occipital bone.
