Accident Description:

8-yo boy mistook a staging stop for the final stop and started to exit the car. When the vehicle starting up again, his foot was crushed and caught between the side of the car and the unload platform. DOSH found that five other children, ages 5-8 had suffered foot entrapment accidents on the ride since it's opening a year prior. In response to the earlier accidents, Knott's decided to modify the ride, reducing the gap from 50mm to 8mm in the hopes of eliminating the entrapment hazard. Instead, the smaller gap increased the magnitude of injury. DOSH ordered Knott's to make a number of changes, including widening the gap back to 50mm+ and adding sensors that will perform a station stop if they detect something entering the gap.

Injury Description:

Degloving of skin on top of foot, torn tendons and fractures requiring in-patient hospitalization, skin grafts, and physical therapy.
