Certified Playground Safety Inspector (CPSI) Practice Exam – Prep Guide & Practice Test

The maximum height of the standing/sitting surface of a Merry-Go-Round platform for preschool-aged children should NOT be too high as it may be difficult for them to climb onto it or potentially cause them to fall off. Option A, 10 inches, may be too low for children to hold onto the railings comfortably. Option C, 18 inches, and D, 22 inches, are too high and may be unsafe for young children. Therefore, the most suitable option is B, 14 inches, as it provides a moderate height that young children can easily access and safely enjoy the Merry-Go-Round.
