What is the maximum height that the walls of public wading pools can extend above the water line?

The maximum height that the walls of public wading pools can extend above the water line is determined primarily for safety and accessibility reasons. A height of 6 inches is considered appropriate as it allows for ease of entry and exit for users, particularly children and individuals with disabilities, while still providing a barrier to the water. This height ensures that water does not spill over excessively while keeping the pool area safe and manageable.

Given this context, the regulation reflects best practices in pool design, encouraging an atmosphere where wading pools remain enjoyable and safe for all visitors without the risk of unintended hazards.
