Under intense summer heat and direct sunlight, the surface of a rainbow slide can indeed become dangerously hot, posing a real safety hazard. Because these slides are typically made from HDPE (high-density polyethylene), the material absorbs heat quickly and retains it, turning into a hidden burn risk in the open sun. When the surface temperature exceeds 50°C (122°F), direct skin contact can easily cause blisters; at 60°C (140°F) and above, even brief contact can result in varying degrees of burns. This risk is especially high for children, whose skin is much more sensitive.

To mitigate this, we strongly recommend that operators install shade structures or use water-spraying cooling systems during peak summer months. Additionally, it is best to schedule rides for the cooler early morning or late afternoon hours. Visitors should always test the surface temperature with the back of their hand before sliding and avoid direct skin contact with the track to prevent accidental burns.
