Horizontal ladders intended for school-age children require a take-off/landing platform height above the protective surface of no more than?

This is because it is important for children to have easy access to the ladder without the risk of falling from a high platform. Having a take-off/landing platform height above the protective surface of no more than 36 inches meets safety standards and reduces the potential for injuries. Options A and B are incorrect as they provide a lower platform height, which may be too low for older children to safely use the ladder. Option D is incorrect as it exceeds the recommended height, increasing the risk of injury from a fall. It is important to adhere to these standards when designing playground equipment for children.
