CPSI Core Knowledge Areas Questions and Answers 3 — Questions and Answers
Question 1: According to ASTM F1292, what is the maximum acceptable impact attenuation expressed as HIC (Head Injury Criterion) for playground surfacing?
- 500
- 1000 (Correct answer)
- 700
- 1500
Correct answer: 1000
ASTM F1292 sets the HIC threshold at 1000; surfacing that produces a HIC value above 1000 is considered inadequate for fall attenuation.
Question 2: What is the minimum depth of unitary rubber surfacing required to meet fall-height standards when installed over a hard surface such as asphalt?
- The manufacturer's tested depth for the intended fall height (Correct answer)
- Always 6 inches regardless of fall height
- Always 12 inches regardless of fall height
- Depth is irrelevant for unitary surfacing
Correct answer: The manufacturer's tested depth for the intended fall height
Unitary surfacing must be installed at the manufacturer's tested and certified depth corresponding to the equipment's critical fall height.
Question 3: Under CPSC guidelines, what minimum clearance zone (use zone) is required around a single-axis swing on each side in the direction of swing travel?
- Twice the height of the pivot point above the ground (Correct answer)
- 6 feet
- The height of the pivot point above the ground
- 8 feet minimum
Correct answer: Twice the height of the pivot point above the ground
The CPSC Handbook specifies that the use zone in front of and behind a swing must extend a distance equal to twice the height of the pivot point above the protective surfacing.
Question 4: Which ASTM standard specifically governs performance requirements for impact-attenuating surfacing materials used under playground equipment?
- ASTM F1292 (Correct answer)
- ASTM F1148
- ASTM F2373
- ASTM F1951
Correct answer: ASTM F1292
ASTM F1292 is the standard specification for impact attenuation of surfacing materials within the use zone of playground equipment.
Question 5: A CPSI finds that a steel slide has a surface temperature of 165°F on a sunny summer day. What is the primary standard concern this raises?
- Thermal burn hazard to children (Correct answer)
- Structural fatigue risk
- Slip resistance failure
- Entrapment hazard
Correct answer: Thermal burn hazard to children
Elevated surface temperatures on metal slides and other equipment components can cause serious contact burns, making thermal hazard a primary safety concern.
Question 6: What is the maximum allowable opening size in a guardrail or platform barrier to prevent head entrapment according to CPSC and ASTM F1487?
- Less than 3.5 inches or greater than 9 inches (Correct answer)
- Less than 2 inches or greater than 10 inches
- Less than 4 inches or greater than 8 inches
- Less than 3 inches or greater than 7 inches
Correct answer: Less than 3.5 inches or greater than 9 inches
Openings must be either smaller than 3.5 inches (too small for a child's head to enter) or larger than 9 inches (too large to trap a head) to avoid the entrapment zone.
Question 7: Which organization publishes the Handbook for Public Playground Safety that serves as a primary reference document for CPSI candidates?
- U.S. Consumer Product Safety Commission (CPSC) (Correct answer)
- National Program for Playground Safety (NPPS)
- ASTM International
- National Recreation and Park Association (NRPA)
Correct answer: U.S. Consumer Product Safety Commission (CPSC)
The CPSC publishes the Handbook for Public Playground Safety (Publication #325), which is a key reference for playground safety inspectors.
