Free CPSI Equipment and Site Design Questions and Answers — Questions and Answers
Question 1: A designer is planning a new playground for a community park that will serve both toddlers (ages 2-5) and school-aged children (ages 5-12). Which of the following site design choices is MOST critical for minimizing injuries and conflicts between the different age groups?
- Placing the swing sets for both groups next to each other for easier supervision.
- Using a single, large sand play area for all children to encourage interaction.
- Creating distinct play areas for each age group, separated by a buffer zone. (Correct answer)
- Installing the tallest slide in the center of the playground to act as a focal point.
Correct answer: Creating distinct play areas for each age group, separated by a buffer zone.
CPSC and ASTM guidelines strongly recommend separating play areas for different age groups to prevent injuries caused by inappropriate use of equipment by younger children and to minimize conflicts arising from the more vigorous play of older children. A buffer zone, such as a pathway or landscape feature, enhances this separation.
Question 2: When inspecting a vertical rung ladder on a piece of equipment intended for children ages 5-12, what is the maximum allowable vertical distance between the centerlines of adjacent rungs according to ASTM F1487?
- 9 inches
- 12 inches (Correct answer)
- 15 inches
- 18 inches
Correct answer: 12 inches
According to ASTM F1487, the vertical distance between the centerlines of rungs on a ladder used for access or egress shall not exceed 12 inches. This spacing is designed to be manageable for the intended age group without creating a potential head entrapment situation.
Question 3: Which of the following is a primary requirement for an accessible route WITHIN a public play area, according to the 2010 ADA Standards for Accessible Design?
- The route must connect the playground entry/exit points to the accessible play components. (Correct answer)
- The route must be constructed entirely of engineered wood fiber to ensure impact attenuation.
- The running slope of the route must not exceed a 1:12 ratio.
- Handrails must be present on both sides of the entire accessible route.
Correct answer: The route must connect the playground entry/exit points to the accessible play components.
The fundamental purpose of an accessible route within a play area is to provide a continuous, unobstructed path that connects the site arrival points with the accessible play components. While factors like surface material and slope are critical aspects of the route's compliance, the essential requirement is the connection it provides for users with disabilities.
Question 4: An inspector is measuring the use zone for a standalone, single-occupancy spring rocker. What is the minimum required use zone dimension that must surround this piece of equipment?
- A 4-foot clear area in all directions from the equipment's perimeter.
- A 6-foot clear area in all directions from the equipment's perimeter. (Correct answer)
- A 6-foot clear area in the front and back, with 4 feet on the sides.
- A 9-foot clear area in all directions from the equipment's perimeter.
Correct answer: A 6-foot clear area in all directions from the equipment's perimeter.
According to the CPSC Handbook and ASTM F1487, stationary equipment like spring rockers requires a minimum use zone of 6 feet (72 inches) in all directions, measured from the perimeter of the equipment. This provides a clear space to prevent impact with other equipment or users if a child falls or dismounts unexpectedly.
Question 5: A CPSI is inspecting the footings of newly installed playground equipment set in concrete. What is the MOST critical safety requirement regarding the top of the concrete footing within a use zone?
- It must be painted with a weather-resistant coating.
- It must be at least 24 inches in diameter for stability.
- It must be located below the top of the required protective surfacing. (Correct answer)
- It must be stamped with the installation date for record-keeping.
Correct answer: It must be located below the top of the required protective surfacing.
To prevent a trip hazard and ensure that a child falling onto the surface is protected from impact with a hard object, all footings must be installed so that their tops are below the level of the required protective surfacing. An exposed footing creates a significant and dangerous impact hazard.
Question 6: Which of the following design elements is explicitly identified as a potential entanglement hazard on playground equipment according to ASTM F1487?
- A chain with links that have openings smaller than 0.19 inches.
- A vertical grab bar with a diameter of 1.5 inches.
- An S-hook on a swing chain that has been closed to a gap of 0.04 inches.
- A bolt end that projects perpendicular from a post with no threads showing. (Correct answer)
Correct answer: A bolt end that projects perpendicular from a post with no threads showing.
ASTM F1487 identifies certain projections as potential entanglement hazards. A bolt end that projects from a surface, even without threads, can catch a drawstring or an item of clothing, posing a serious risk. S-hooks must be closed (gap no greater than 0.04 inches) to prevent entanglement, and small chain links and properly sized grab bars are generally not considered entanglement hazards.
