CPSI Equipment and Site Design Requirements Questions and Answers 4 — Questions and Answers
Question 1: Under ASTM F1487, what is the minimum required clear height above protective surfacing beneath climbing components?
- The component's highest climbing point
- The component's critical height (Correct answer)
- 6 feet regardless of equipment height
- The manufacturer's stated fall height plus 6 inches
Correct answer: The component's critical height
The critical height of the equipment determines the minimum depth of protective surfacing, not a fixed clearance above it.
Question 2: ASTM F1487 requires guardrails to prevent accidental falls on elevated platforms. At what platform height must guardrails be provided for equipment intended for ages 5–12?
- Above 18 inches
- Above 20 inches
- Above 24 inches (Correct answer)
- Above 30 inches
Correct answer: Above 24 inches
Guardrails are required on elevated surfaces more than 24 inches above the ground for equipment intended for school-age children (5–12).
Question 3: What is the maximum permitted protrusion (bolt extension) beyond a nut on playground equipment per ASTM F1487?
- 1/16 inch
- 1/8 inch (Correct answer)
- 1/4 inch
- 1/2 inch
Correct answer: 1/8 inch
Bolt ends must not protrude more than 1/8 inch beyond the nut to minimize clothing snag and laceration hazards.
Question 4: According to ASTM F1487, what is the minimum overhead clearance required above any play component to prevent head impact on overhead obstacles?
- 6 feet
- 7 feet
- 7.5 feet (Correct answer)
- 8 feet
Correct answer: 7.5 feet
ASTM F1487 requires a minimum clearance of 7.5 feet above any component where a child could stand or be elevated.
Question 5: What is the primary purpose of an 'accessible route' requirement on a playground per the ADA and ASTM F1487?
- To allow maintenance vehicles to reach equipment
- To ensure children with disabilities can access play components (Correct answer)
- To provide emergency egress paths
- To separate age groups within the playground
Correct answer: To ensure children with disabilities can access play components
Accessible routes connect accessible parking and entries to accessible play components so children with disabilities can participate.
Question 6: Per ASTM F1487, what type of surface material is NOT considered an acceptable unitary protective surface for playgrounds?
- Poured-in-place rubber
- Rubber tiles
- Concrete (Correct answer)
- Bonded rubber mulch
Correct answer: Concrete
Concrete has no impact attenuation and is explicitly prohibited as a protective surfacing material under ASTM F1487.
Question 7: Under ASTM F1487, what is the minimum angle at which a ladder rung must be oriented relative to horizontal to prevent a foot from slipping off?
- Exactly horizontal (0 degrees) (Correct answer)
- Tilted back at 5 degrees
- Tilted back at 10 degrees
- Tilted back at 15 degrees
Correct answer: Exactly horizontal (0 degrees)
Ladder rungs must be horizontal (0 degrees) so feet land flat and evenly, minimizing slip-off risk.
