CPSI ASTM and CPSC Standards 4 — Questions and Answers
Question 1: Under ASTM F1487, what is the maximum allowable slope for a ramp without handrails before handrails become required?
- 1:12 slope (approximately 5 degrees) (Correct answer)
- 1:8 slope (approximately 7 degrees)
- 1:20 slope (approximately 3 degrees)
- 1:6 slope (approximately 9 degrees)
Correct answer: 1:12 slope (approximately 5 degrees)
ASTM F1487 generally aligns with accessibility guidelines requiring handrails on ramps exceeding a 1:12 slope ratio.
Question 2: Which ASTM standard specifically addresses the safety of home playground equipment?
- ASTM F1148 (Correct answer)
- ASTM F1487
- ASTM F2373
- ASTM F1292
Correct answer: ASTM F1148
ASTM F1148 is the consumer safety performance specification for home playground equipment, distinct from F1487 which covers public equipment.
Question 3: The CPSC guideline for use zones states that when two adjacent pieces of equipment are close together, the use zones may overlap under which condition?
- The use zones of stationary equipment may overlap each other but never those of moving equipment (Correct answer)
- All use zone overlaps are permitted as long as the total area is sufficient
- Use zones may never overlap under any circumstance
- Overlaps are allowed only for equipment under 2 feet in height
Correct answer: The use zones of stationary equipment may overlap each other but never those of moving equipment
CPSC guidelines specify that while use zones of stationary equipment may overlap, the use zones of moving equipment (e.g., swings, merry-go-rounds) must never overlap with any other use zone.
Question 4: According to ASTM F1487, the test for entrapment in a 'torso entrapment' scenario uses a template simulating a child's torso of what dimensions?
- 12 inches x 18 inches (Correct answer)
- 9 inches x 14 inches
- 15 inches x 20 inches
- 10 inches x 16 inches
Correct answer: 12 inches x 18 inches
ASTM F1487 uses a 12-inch by 18-inch torso template to evaluate whether openings in equipment could trap a child's body.
Question 5: The CPSC Handbook categorizes playground hazards into which two broad types?
- Mechanical and non-mechanical hazards (Correct answer)
- Design hazards and maintenance hazards
- Structural hazards and fall hazards
- Entrapment hazards and surfacing hazards
Correct answer: Mechanical and non-mechanical hazards
The CPSC Handbook broadly classifies playground hazards as mechanical (relating to moving parts and equipment mechanics) and non-mechanical.
Question 6: According to ASTM F1487, which of the following is a 'designated play surface' that requires consideration of fall height?
- A platform that a child can stand on (Correct answer)
- A climbing rung below 18 inches
- Any decorative element attached to equipment
- A ground-level sand play area
Correct answer: A platform that a child can stand on
ASTM F1487 defines a designated play surface as any elevated surface intended for standing, and fall height is measured from it.
Question 7: What does the Head Injury Criteria (HIC) value of 1000 represent in ASTM F1292 testing?
- The maximum acceptable HIC score below which serious head injury is unlikely (Correct answer)
- The minimum score a surface must exceed to be approved
- The average HIC for wood chip surfacing at 6 inches
- The threshold at which a surface automatically passes inspection
Correct answer: The maximum acceptable HIC score below which serious head injury is unlikely
A HIC value below 1000 is the maximum acceptable threshold indicating the surface can reduce the risk of life-threatening head injury.
