,GENERAL & DEFINITIONS
1. What is the minimum height of the upper guardrail for children 2–5 years old?
A) 29"
B) 32"
C) 35"
D) 25"
Correct Answer: A) 29"
Rationale: ASTM F1487 and CPSC guidelines require the upper guardrail for preschool-
,aged children (2–5) to be a minimum of 29 inches high to prevent falls while allowing
visibility and access.
2. What is the minimum use zone of the slide exit region?
A) 60"
B) 48"
C) 84"
D) 72"
Correct Answer: D) 72"
Rationale: The slide exit use zone must be a minimum of 72 inches and can extend up to
96 inches. It is measured from the end of the slide chute and must not overlap with other
equipment use zones.
3. For completely bounded non-rigid openings, how many pounds of force to push
through an opening?
A) 50#
B) 100#
C) 75#
D) 30#
Correct Answer: A) 50#
Rationale: Non-rigible openings (e.g., netting or flexible materials) must resist a 50-
pound force to prevent head or limb entrapment. If 50# of force pushes through, the
opening is considered a hazard.
4. What is the minimum diameter of rungs on a rigid climbing apparatus?
A) 1.10"
, B) 0.95"
C) 1.25"
D) 0.75"
Correct Answer: A) 1.10"
Rationale: Rungs must be at least 1.10 inches in diameter to provide a secure grip for
children and prevent small hands from slipping through or becoming entrapped.
5. The common cause of injury is caused by:
A) Distance between the top of the walking surface to fall material.
B) PS 12" max SA 18" max.
C) PS (2–5 yo) min 9"–12" max SA (5–12 yo) min 9"–15" max.
D) Impact 11% 8% by stationary 3% moving equip.
Correct Answer: D) Impact 11% 8% by stationary 3% moving equip.
Rationale: Impact injuries (falls onto surfaces) are the most common mechanism of
playground injury. Stationary equipment accounts for 8% and moving equipment for 3%
of impact-related injuries.
6. Define Impact Attenuation.
A) The ability of a surface to reduce and dissipate the energy of a falling body.
B) The ability of a surface to enhance the energy of a falling body.
C) The capacity of a surface to increase the force of impact.
D) The property of a surface to amplify the energy of a falling object.
Correct Answer: A) The ability of a surface to reduce and dissipate the energy of a
falling body.
Rationale: Impact attenuation is a measure of how well a surfacing material absorbs
shock to reduce injury severity during a fall.
