CPSI Entrapment and Protrusion Hazard Testing Questions and Answers 5 — Questions and Answers
Question 1: An inspector evaluates a composite structure where a ladder's top rung creates a partially bound opening with the platform edge measuring 5 inches. What is the correct assessment?
- Safe — partially bound openings are only hazardous below 3.5 inches
- Hazardous — 5 inches falls within the entrapment zone for partially bound openings (Correct answer)
- Safe — ladder rungs are exempt because children must grip them
- Hazardous only if the platform height exceeds 6 feet
Correct answer: Hazardous — 5 inches falls within the entrapment zone for partially bound openings
A 5-inch partially bound opening between a ladder rung and platform edge is within the 3.5–9 inch entrapment zone and must be cited.
Question 2: When inspecting a tire swing, a CPSI discovers that the drainage hole at the bottom measures 1.5 inches in diameter. What hazard does this present?
- None — 1.5 inches is below the entrapment threshold
- Finger or toe entrapment — the hole is large enough to admit a small digit but trap it (Correct answer)
- Head entrapment — 1.5 inches can trap a young child's neck
- Impalement hazard from the hole edges
Correct answer: Finger or toe entrapment — the hole is large enough to admit a small digit but trap it
A 1.5-inch hole can admit a small finger or toe but prevent its removal, creating an entrapment hazard for young children.
Question 3: A CPSI re-inspection follows a repair where a missing bolt was replaced. The new bolt extends 0.45 inch from the surface with a flat head. Should this be cited?
- No — 0.45 inch is below the 0.5-inch protrusion threshold (Correct answer)
- Yes — any protrusion from a repaired area must be cited regardless of length
- No — flat-headed bolts are exempt from protrusion standards
- Yes — the bolt must be countersunk to be compliant
Correct answer: No — 0.45 inch is below the 0.5-inch protrusion threshold
A protrusion of 0.45 inch is below the 0.5-inch threshold and does not meet the criteria for a protrusion hazard citation.
Question 4: A horizontal ladder has rungs spaced 18 inches apart. What entrapment concern, if any, do the spaces between the rungs present?
- None — overhead rungs are not subject to entrapment standards
- Head entrapment — if rung diameter and spacing create an opening within 3.5–9 inches (Correct answer)
- Torso entrapment — children could fall through the spaces
- Protrusion hazard from the rung end caps
Correct answer: Head entrapment — if rung diameter and spacing create an opening within 3.5–9 inches
The combination of rung diameter and spacing on overhead ladders can create partially bound openings that fall within the head entrapment zone.
Question 5: During a CPSI audit, a wood beam has a splinter protruding 0.6 inch at a right angle to the surface. How is this classified?
- Entrapment hazard, because it forms a partially bound opening
- Protrusion hazard, because it exceeds the 0.5-inch threshold (Correct answer)
- Maintenance issue only, not a CPSC-defined hazard
- Acceptable if the splinter is located above 48 inches in height
Correct answer: Protrusion hazard, because it exceeds the 0.5-inch threshold
A splinter or wood protrusion exceeding 0.5 inch is classified as a protrusion hazard under CPSC guidelines regardless of material type.
Question 6: A chain link fence adjacent to a playground structure has diamond-shaped openings that measure 2.5 inches at their widest point. What is the entrapment classification?
- No entrapment hazard — openings are below 3.5 inches (Correct answer)
- Head entrapment hazard — diamond openings always require the head probe test
- Clothing entrapment hazard — the narrow points can snag drawstrings
- Torso entrapment hazard — children can squeeze through diagonally
Correct answer: No entrapment hazard — openings are below 3.5 inches
Openings with a maximum dimension below 3.5 inches fall outside the head entrapment zone and do not present a head entrapment hazard.
Question 7: A CPSI inspector is evaluating a crawl tube with an interior diameter of 18 inches. What is the entrapment concern for this component?
- Head entrapment — 18 inches falls within a secondary entrapment zone
- None related to entrapment — the diameter exceeds 9 inches and children can pass through freely (Correct answer)
- Torso entrapment — the tube may be too narrow for older children
- Protrusion hazard from internal seams of the tube
Correct answer: None related to entrapment — the diameter exceeds 9 inches and children can pass through freely
An 18-inch interior diameter exceeds the 9-inch upper boundary of the head entrapment zone, so the tube does not present a head entrapment hazard.
