  1. A merry-go-round platform has a measured lip height of 2.5 inches at the outer edge. According to ASTM F1487, what is the maximum allowable lip height to prevent tripping hazards?

    Answer: 2 inches

    ASTM F1487 specifies that platform lips or protrusions on rotating equipment must not exceed 2 inches to minimize tripping and entrapment hazards.

  2. During inspection of a spring rocker, the inspector notices the spring coil has a gap of 35 mm when the equipment is in its rest position. What is the primary concern?

    Answer: Finger and hand entrapment in the coil gaps

    Spring coil gaps between 9 mm and 25 mm (or exceeding maximum limits) create finger and hand entrapment hazards that must be evaluated per ASTM F1487.

  3. When assessing the use zone for a rotating tire swing, the inspector should measure the use zone radius from:

    Answer: The outer edge of the tire at full extension in all directions

    The use zone for a tire swing extends from the outer edge of the tire at its maximum travel point in all directions to ensure adequate clearance.

  4. A spring rocking horse has a maximum displacement angle of 28 degrees from vertical. What does ASTM F1487 specify as the maximum allowable rocking angle?

    Answer: 25 degrees

    ASTM F1487 limits the maximum rocking or gliding angle of rocking equipment to 25 degrees from the vertical rest position to prevent tip-over.

  5. An inspector finds that a merry-go-round's bearings produce a rhythmic grinding noise during rotation. The equipment otherwise passes visual inspection. What is the correct action?

    Answer: Remove from service until bearings are replaced or professionally evaluated

    Grinding bearing noise indicates potential mechanical failure that could cause sudden equipment malfunction; the equipment must be removed from service until repaired.

  6. According to CPSC Handbook guidelines, what minimum ground clearance must be maintained between the underside of a rotating platform and the ground surface?

    Answer: 7 inches

    CPSC guidelines require at least 7 inches of clearance between the lowest moving part of rotating equipment and the ground to prevent crush injuries.

  7. A seesaw has a maximum height of 28 inches at its highest point. Which ASTM F1487 requirement is directly relevant to this measurement?

    Answer: The fall height used to determine required surfacing depth

    The maximum height of the seesaw seat determines the critical fall height, which directly dictates the required depth and type of impact-attenuating surfacing beneath the equipment.
