Certified Playground Safety Inspector (CPSI) Practice Exam

What is the minimum radius requirement on corners and edges for suspended members, such as rings, on upper body equipment?

1. .15 inches

2. .25 inches

3. .35 inches

4. .45 inches

The correct answer is: .25 inches

Corner and edge radius requirements for suspended members, such as rings, on upper body equipment are typically based on safety and ergonomics considerations. These requirements aim to prevent any sharp or uncomfortable edges and corners that could potentially cause injury or discomfort during use. In this case, the minimum radius requirement is .25 inches as it provides a balance between safety and functionality. Option A (.15 inches) may be too small and potentially cause discomfort in the hands and fingers while performing exercises. Option C (.35 inches) and D (.45 inches) may be too large, resulting in a bulkier or less stable design for the equipment. Thus, option B is the most suitable choice for this scenario. However, it is important to note that specific radius requirements may vary depending on the type of equipment and intended use.
