Certified Playground Safety Inspector (CPSI) Practice Exam 2025 – All-in-One Guide to Exam Success

The requirement for the radius curvature of the sliding surface in the exit region is foundational for ensuring safety during playground use. A radius curvature of 30 inches or greater is recommended because it helps to minimize abrupt transitions and potential hazards that can lead to injuries. This standard takes into account the physics of how children slide and the necessary deceleration as they exit the slide, which can significantly reduce the risk of falling or colliding with surrounding surfaces.

A larger radius curvature allows for a smoother transition, which is particularly important for maintaining a safe sliding experience. A smaller radius could increase the chances of a child losing control or not exiting safely from the slide. Therefore, the standard of having a curvature of at least 30 inches is designed to safeguard against these potential risks by providing adequate space and gradual curvature for a safe descent from the slide.

This requirement reflects best practices in playground safety design, emphasizing that safety features must accommodate the behavior and movements of the children using the equipment.
