Certified Playground Safety Inspector (CPSI) Practice Exam

The correct minimum width for footrests on Spring Rockers is 3.5 inches. Option A, 2.5 inches, is too narrow and would not provide enough support for the feet. Option B, 3 inches, may also be too narrow and could potentially cause discomfort for the user. Option D, 4 inches, is wider than the minimum requirement and may not be as comfortable for all users. Therefore, option C, 3.5 inches, is the best choice for both comfort and safety.
