CPSI Rotating Equipment and Rocking Equipment Standards 5

Question 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?

Accepted Answer

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

Answer

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.

Question 2

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

Accepted Answer

Do not present protrusions exceeding 8 mm that could catch clothing

Answer

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

Question 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:

Accepted Answer

Remove from service immediately until the cover is replaced

Answer

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.

Question 4

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

Accepted Answer

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

Answer

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.

Question 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:

Accepted Answer

Bearing friction and entrapment risk

Answer

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