CPSI ASTM and CPSC Standards Questions and Answers 5 — Questions and Answers
Question 1: ASTM F1487 identifies 'crush and shear points' as a specific mechanical hazard. Which of the following best describes this hazard?
- Sharp edges on cut metal components
- Moving parts that can catch and compress body parts (Correct answer)
- Rough surfaces that abrade skin on contact
- Pinch points created only when equipment is misassembled
Correct answer: Moving parts that can catch and compress body parts
Crush and shear points under ASTM F1487 involve moving parts — such as merry-go-round mechanisms — that can catch and compress fingers, hands, or other body parts.
Question 2: According to the CPSC Handbook, what is the recommended maximum height for climbing equipment intended for children ages 2–5 years (preschool age)?
- 4 feet (Correct answer)
- 5 feet
- 6 feet
- 7 feet
Correct answer: 4 feet
The CPSC Handbook recommends that equipment intended for preschool-age children (2–5 years) have a maximum height of 4 feet to limit fall severity.
Question 3: Which ASTM standard provides the specification for engineered wood fiber (EWF) used as playground surfacing material?
- ASTM F1292
- ASTM F2075 (Correct answer)
- ASTM F1951
- ASTM F3012
Correct answer: ASTM F2075
ASTM F2075 establishes the specification for engineered wood fiber used as playground protective surfacing, covering particle size, composition, and contamination limits.
Question 4: Under ASTM F1487, what is the maximum allowable gap between the bottom of a platform guardrail and the platform surface for equipment designed for children 5 years and younger?
- 2 inches
- 3.5 inches (Correct answer)
- 4 inches
- 6 inches
Correct answer: 3.5 inches
ASTM F1487 limits the bottom gap of guardrails to 3.5 inches on equipment for children 5 and under, preventing small children from sliding under the rail.
Question 5: The CPSC Handbook recommends that swings with full-bucket seats (designed for infants) have what type of use zone separation from tot and school-age swings?
- No separation required if color-coded
- Separated by a physical barrier or significant distance (Correct answer)
- Separated only by signage
- They must be installed at least 3 feet apart on the same bay
Correct answer: Separated by a physical barrier or significant distance
CPSC recommends that infant bucket swings be physically separated from tot and school-age swings to prevent older children from colliding with infants.
Question 6: According to ASTM F1487, what is the minimum height above a platform at which a guardrail is required for school-age children (5–12 years)?
- 18 inches
- 20 inches
- 24 inches (Correct answer)
- 30 inches
Correct answer: 24 inches
ASTM F1487 requires guardrails on platforms higher than 30 inches for preschoolers and higher than 48 inches for school-age children, but the standard guardrail height minimum is 24 inches above the platform surface.
Question 7: Which of the following correctly describes how the CPSC Handbook addresses 'tripping hazards' in playground surfacing installation?
- Edging borders must be flush with or below the surrounding grade (Correct answer)
- Edging must protrude at least 1 inch to retain loose fill
- Concrete borders are preferred for durability
- Tripping hazards are only regulated by ASTM, not CPSC
Correct answer: Edging borders must be flush with or below the surrounding grade
The CPSC Handbook specifies that containment borders and edging must be flush with or below the surrounding grade so they do not create tripping hazards for children.
