CPSI - Certified Playground Safety Inspector Equipment and Site Design Requirements 1 — Questions and Answers
Question 1: What is the minimum use zone extension required beyond the exit point at the bottom of a playground slide?
- 4 feet
- 6 feet (Correct answer)
- 8 feet
- 10 feet
Correct answer: 6 feet
CPSC guidelines require a minimum 6-foot use zone extending from the bottom exit of a slide chute to protect children as they exit. This is the same standard minimum use zone distance applied around most stationary playground equipment.
Question 2: According to CPSC guidelines, what is the maximum recommended platform height for playground equipment designated for children ages 2–5?
- 24 inches
- 28 inches
- 32 inches (Correct answer)
- 36 inches
Correct answer: 32 inches
CPSC recommends a maximum platform height of 32 inches for preschool-age equipment (ages 2–5) to limit fall height and reduce the severity of injuries, reflecting the smaller stature and developmental stage of young children.
Question 3: To eliminate head entrapment hazards, openings in playground equipment must be either smaller than ___ or larger than ___.
- 3 inches and 8 inches
- 3.5 inches and 9 inches (Correct answer)
- 4 inches and 10 inches
- 3.5 inches and 12 inches
Correct answer: 3.5 inches and 9 inches
CPSC and ASTM F1487 require openings to be either less than 3.5 inches (too small for a child's head to enter) or greater than 9 inches (large enough for a head to pass through freely), eliminating the dangerous entrapment zone between these two dimensions.
Question 4: At what minimum platform height must guardrails or protective barriers be provided on equipment designed for children ages 5–12?
- 20 inches
- 25 inches
- 30 inches (Correct answer)
- 36 inches
Correct answer: 30 inches
CPSC guidelines require guardrails or barriers on platforms 30 inches or higher for school-age (5–12) equipment to prevent unintentional falls from elevated surfaces. Note that the threshold is lower (20 inches) for preschool-age equipment.
Question 5: What is the minimum use zone required around the outermost reach of rotating playground equipment such as a merry-go-round?
- 4 feet
- 6 feet (Correct answer)
- 8 feet
- 10 feet
Correct answer: 6 feet
CPSC guidelines require a minimum 6-foot use zone measured from the outermost reach of rotating equipment in all directions when the equipment is in motion, accounting for children who may be ejected or fall near the structure.
Question 6: According to ASTM F1487, bolt ends and other hardware protrusions must not extend more than how far beyond the fastening device (nut)?
- 1 thread length
- 2 thread lengths (Correct answer)
- 3 thread lengths
- 5 millimeters
Correct answer: 2 thread lengths
ASTM F1487 limits exposed hardware protrusions — such as bolt ends — to no more than 2 thread lengths beyond the fastening nut. Protrusions exceeding this create impalement risks and clothing entanglement hazards that can trap or injure children.
