Non-exempt rides must be inspected annually by a professional engineer or qualified inspector who certifies the ride meets state standards and NDT is up to date. State officials inspect fixed-site rides at permanent parks every 6 months; portable rides at every setup. Large parks (over 1000 employees) are exempt from public safety inspections of their rides.
State officials have authority to investigate serious accidents at carnivals and non-exempt permanent parks. Accidents at exempt facilities (large parks, trade shows) are not investigated by public safety authorities.
Non-exempt parks and traveling carnivals are required by law to report ride-related death or injury requiring immediate transport to a medical facility. Exempt facilities (large parks and trade shows) are exempt from mandatory reporting. In 2001, Disney, Universal and Busch voluntarily agreed to report medical symptoms of patrons who die or are immediately admitted to the hospital after riding their thrill rides.
Rides operated amusement parks with more than 1000 employees, or at trade shows, are exempt from state safety regulation.
