CPSI Core Knowledge Areas 3 — Questions and Answers
Question 1: A head entrapment opening is defined as one that allows a 9-inch probe to pass through but does NOT allow a probe of what minimum diameter to pass through?
- 7 inches
- 9 inches
- 11 inches (Correct answer)
- 13 inches
Correct answer: 11 inches
Head entrapment risk exists when an opening allows a 9-inch probe to pass but prevents an 11-inch probe from passing, trapping a child's head.
Question 2: What type of inspection involves a detailed hands-on examination of structural integrity, hardware, and surface conditions typically performed every 1–3 months?
- Routine operational inspection
- High-frequency visual inspection
- Periodic maintenance inspection (Correct answer)
- Annual comprehensive inspection
Correct answer: Periodic maintenance inspection
Periodic maintenance inspections are detailed hands-on checks of structural integrity, hardware, and surfacing typically performed every 1–3 months.
Question 3: What is the minimum depth of loose-fill wood chips or engineered wood fiber required under equipment with a 10-foot fall height?
- 6 inches
- 9 inches
- 12 inches (Correct answer)
- 15 inches
Correct answer: 12 inches
CPSC guidelines recommend a minimum of 12 inches of loose-fill wood chips or engineered wood fiber for equipment with up to 10 feet of fall height.
Question 4: Which ASTM standard specifically addresses safety performance specifications for playground surfacing materials?
- ASTM F1292 (Correct answer)
- ASTM F1487
- ASTM F2223
- ASTM F2075
Correct answer: ASTM F1292
ASTM F1292 establishes impact attenuation performance specifications for playground surfacing materials, measuring HIC and g-max values.
Question 5: A 'trip hazard' on a playground is most commonly defined as a vertical elevation change greater than:
- ¼ inch
- ½ inch (Correct answer)
- 1 inch
- 1½ inches
Correct answer: ½ inch
A vertical elevation change greater than ½ inch in a pedestrian pathway or use zone is generally considered a trip hazard.
Question 6: When assessing play value, a CPSI should recognize that challenging equipment is important because:
- It reduces maintenance costs over time
- It meets ADA compliance requirements
- It supports children's physical and cognitive development through managed risk (Correct answer)
- It reduces the number of required use zone inspections
Correct answer: It supports children's physical and cognitive development through managed risk
Challenge is an intentional aspect of playground design that supports children's physical, cognitive, and social development through age-appropriate managed risk.
Question 7: Under ASTM F1487, which component requires a guardrail or protective barrier on elevated platforms for children ages 5–12 at heights above 30 inches?
- All elevated platforms require full enclosure at any height
- Platforms between 20–30 inches require guardrails only
- Platforms above 30 inches require guardrails or barriers to prevent unintended falls (Correct answer)
- Only platforms above 48 inches require protective barriers
Correct answer: Platforms above 30 inches require guardrails or barriers to prevent unintended falls
ASTM F1487 requires guardrails or protective barriers on elevated platforms above 30 inches for school-age children (5–12) to prevent unintended falls.
