CPSI Rotating Equipment and Rocking Equipment Standards 4

Question 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?

Accepted Answer

2 inches

Answer

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

Question 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?

Accepted Answer

Finger and hand entrapment in the coil gaps

Answer

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.

Question 3

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

Accepted Answer

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

Answer

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.

Question 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?

Accepted Answer

25 degrees

Answer

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

Question 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?

Accepted Answer

Remove from service until bearings are replaced or professionally evaluated

Answer

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