Safety Notice: Who Should Not Ride the Rainbow Slide?

While the Rainbow Slide is colorful and exciting, it involves high speeds and sudden drops. To ensure everyone's safety, the following individuals are strictly prohibited from riding:

1. Individuals with Pre-existing Medical Conditions
Guests with heart disease, high blood pressure, coronary heart disease, epilepsy, vertigo, cardiovascular or cerebrovascular diseases, cervical spine issues, or psychiatric disorders must not ride. The centrifugal force and acceleration during the descent may trigger sudden medical emergencies.

2. Special Health Conditions & Physical Limitations
Pregnant women are strictly prohibited from riding. Additionally, seniors over 60, individuals recovering from recent surgeries or unhealed fractures, and those under the influence of alcohol, drugs, or certain medications that cause physical discomfort or impaired judgment are not permitted to ride.

3. Guests Not Meeting Height, Weight, or Age Requirements
Safety limits vary slightly by venue, but generally, riders must be at least 1.2m to 1.4m tall and weigh between 30kg and 100kg. Children under 6 are not allowed to ride without direct adult supervision.

Important Reminder: Before riding, please carefully read the park's Passenger Safety Guidelines. Always assess your physical condition honestly. Do not conceal medical conditions or attempt to ride if you do not meet the requirements. Safety always comes first!
