CPSI ASTM and CPSC Standards Questions and Answers 4 — Questions and Answers
Question 1: ASTM F1487 defines the 'use zone' as the surface area beneath and around playground equipment where a child falling must be protected. What is the minimum use zone radius required around most freestanding equipment?
- 4 feet
- 6 feet (Correct answer)
- 8 feet
- 10 feet
Correct answer: 6 feet
ASTM F1487 requires a minimum 6-foot use zone extending from any point on the equipment in all directions for most freestanding structures.
Question 2: According to the CPSC Handbook, at what age range are separate design considerations recommended to distinguish between equipment intended for 'toddlers' versus 'preschool age' children?
- 6 months–2 years vs. 2–5 years
- 6 months–23 months vs. 2–5 years (Correct answer)
- 1–2 years vs. 3–6 years
- Under 18 months vs. 18 months–5 years
Correct answer: 6 months–23 months vs. 2–5 years
The CPSC Handbook distinguishes toddlers (6–23 months) from preschoolers (2–5 years) to address their very different developmental capabilities.
Question 3: What does ASTM F1951 evaluate specifically for playground surfacing?
- Impact attenuation under heavy rainfall
- Accessibility and wheelchair maneuverability (Correct answer)
- UV degradation resistance
- Chemical leaching into soil
Correct answer: Accessibility and wheelchair maneuverability
ASTM F1951 measures the accessibility of playground surfacing, determining whether it allows wheelchair users to maneuver to and around equipment.
Question 4: Under ASTM F1487, what is the minimum clearance required between adjacent pieces of equipment to prevent children from being caught between structures?
- 3 feet
- 6 feet (Correct answer)
- 9 feet
- 12 feet
Correct answer: 6 feet
ASTM F1487 requires at least 6 feet of clearance between adjacent play structures to ensure use zones do not overlap in a hazardous way.
Question 5: The CPSC Handbook specifies that protective surfacing must be maintained and inspected on what routine basis at a minimum for high-traffic public playgrounds?
- Daily
- Weekly (Correct answer)
- Monthly
- Quarterly
Correct answer: Weekly
The CPSC Handbook recommends weekly inspections of protective surfacing at a minimum for high-use public playgrounds to ensure adequate depth and coverage.
Question 6: According to ASTM F1487, which of the following handrail diameters falls within the acceptable graspability range for school-age children on playground equipment?
- 0.5 to 0.75 inches
- 0.95 to 1.55 inches (Correct answer)
- 1.6 to 2.0 inches
- 2.1 to 2.5 inches
Correct answer: 0.95 to 1.55 inches
ASTM F1487 specifies that graspable handrails for school-age children must have a diameter between 0.95 and 1.55 inches for secure gripping.
Question 7: Under CPSC guidelines, which surfacing material is NOT recommended for use under playground equipment due to inconsistent impact attenuation performance?
- Engineered wood fiber
- Rubber mulch
- Concrete (Correct answer)
- Pea gravel
Correct answer: Concrete
Concrete is explicitly not recommended by CPSC as playground surfacing because it provides essentially no impact attenuation and dramatically increases injury severity.
