Incidents at Six Flags parks

The following is a summary of notable incidents at any of the amusement parks water parks operated by Six Flags Entertainment Corporation. In some cases, these incidents occurred while the park was under different management or ownership.

The Prince George's County Fire Department bomb squad and security personnel were deployed around the park and found two unattended backpacks that were determined not to be explosive. The all-clear was announced after a search of the park around 2:45 p.m. Six Flags announced that the park would be open until 8 p.m. that evening.

From 2004 to September 2007, the Occupational Safety and Health Administration (OSHA) inspected Six Flags parks five different times and found a total of four violations. On September 10, 2007, OSHA cited Great America with 38 safety violations, alleging "multiple serious and repeat violations at the amusement park, ranging from defective emergency brakes on an industrial truck to a lack of labeling procedures for preventing inadvertent machine start-ups." OSHA fined the park US$117,700.
