  1. A newly installed merry-go-round has a deck height of 14 inches. An inspector checks for entanglement hazards at the platform edge. Which condition would most likely create a shear/crush point?

    Answer: A gap of 6 mm between the rotating deck and stationary base ring

    A 6 mm gap between the rotating deck and stationary base ring falls within the entrapment zone (4–12 mm) and creates a shear/crush hazard for fingers.

  2. When inspecting a double-axis spring rocker designed for two riders, the inspector must verify that the footrests:

    Answer: Do not present protrusions exceeding 8 mm that could catch clothing

    ASTM F1487 requires that footrests and all protrusions on play equipment not exceed 8 mm to prevent clothing entanglement that could cause strangulation.

  3. A playground inspector observes that a seesaw's pivot guard cover is cracked but still in place. The seesaw otherwise functions normally. The inspector should:

    Answer: Remove from service immediately until the cover is replaced

    A cracked pivot guard exposes the pivot mechanism, creating entrapment and crush hazards; the equipment must be removed from service until the guard is properly replaced.

  4. Under ASTM F1487, which type of rotating equipment is specifically PROHIBITED on public playgrounds?

    Answer: Equipment that rotates freely without a speed-limiting mechanism only if above 24 inches deck height

    ASTM F1487 prohibits freely rotating equipment (no speed governor) with a deck height above 24 inches, as the combination creates unacceptable fall and ejection risks.

  5. An inspector measures the deceleration of a merry-go-round after a child pushes it. It comes to a complete stop in 8 seconds from full spin. This is MOST relevant to assessing:

    Answer: Bearing friction and entrapment risk

    Deceleration time reflects bearing condition and friction; overly free-spinning bearings increase fall and ejection risk, while excessively resistant bearings may indicate mechanical failure.

  6. A rocking boat designed for 4–5 riders has handholds installed at 36-inch height. An inspector notes one child is standing on the seat. What is the primary hazard classification?

    Answer: Fall hazard due to misuse elevating the effective fall height

    Standing on the seat raises the child's center of gravity above the design fall height, significantly increasing fall severity risk beyond what the surfacing was specified to attenuate.

  7. According to CPSC Handbook guidelines, the use zone around a stationary spring rocking animal must extend at least how far from the equipment's perimeter in all directions?

    Answer: 6 feet

    CPSC guidelines require a minimum 6-foot use zone in all directions around spring rocking equipment to protect children who may fall off during use.
