A hardware bolt on a climber has a hex head that protrudes 0.6 inch but is recessed inside a countersunk hole. How should the inspector measure protrusion?
Answer: From the surface of the equipment to the top of the bolt head
Protrusion is always measured from the equipment's outer surface to the tip of the hardware, not from the recess floor.
What is the primary reason the CPSC specifies a lower bound of 3.5 inches for the head entrapment hazard zone?
Answer: Openings smaller than 3.5 inches are too small for a young child's head to enter
The 3.5-inch lower bound reflects the minimum head breadth of young children — openings smaller than this cannot be entered by the head.
An inspector observes an S-hook on a swing chain with a gap measuring 0.04 inch. What is the correct determination?
Answer: Hazardous — S-hook gaps must be completely closed (0 inch) to be safe
S-hook openings must be completely closed (0-inch gap) to prevent clothing entanglement and entrapment; any measurable gap is a hazard.
A slide handrail has an exposed pipe end with a flat cut (not capped). The pipe wall thickness is 0.1 inch and the inner diameter is 1 inch. What is the primary hazard?
Answer: Finger entrapment inside the pipe bore
Uncapped pipe ends with small inner diameters can trap a child's finger inside the bore, making finger entrapment the primary concern.
During a post-installation inspection, a CPSI finds that a deck board gap measures exactly 3.5 inches. Which action is correct?
Answer: Cite as a hazard — the opening equals the lower boundary of the entrapment zone
An opening that equals 3.5 inches is at the boundary of the entrapment zone and must be cited as a hazard because it can admit a child's head.
What does a CPSI inspector check when using the torso probe (Template B) on a platform opening?
Answer: Whether the opening allows a child to fall through feet-first
The torso probe checks whether an opening is large enough for a child to fall through feet-first, which is the primary fall and entrapment risk for platform openings.
A ring climber has circular handholds with inner diameters of 4 inches. What type of hazard, if any, do these present?
Answer: Head entrapment hazard — 4 inches falls within the 3.5–9 inch zone
A 4-inch inner diameter falls squarely within the 3.5–9 inch head entrapment zone, making these ring handholds a potential entrapment hazard.
