CPSI Entrapment and Protrusion Hazard Testing Questions and Answers 3 — Questions and Answers
Question 1: Which ASTM F1292 test template is specifically used to check for head entrapment openings on playground equipment?
- Template A (small parts cylinder)
- Template B (torso probe)
- Template C (head entrapment probe) (Correct answer)
- Template D (foot probe)
Correct answer: Template C (head entrapment probe)
Template C, the head entrapment probe, is used to identify openings that could trap a child's head during CPSC/ASTM inspections.
Question 2: A partially bound opening measures 4.5 inches at its narrowest point. How should an inspector classify this?
- Safe — below the 5-inch threshold
- Hazardous — falls within the entrapment zone of 3.5 to 9 inches (Correct answer)
- Acceptable if located more than 18 inches off the ground
- Safe only if the opening has no protrusions nearby
Correct answer: Hazardous — falls within the entrapment zone of 3.5 to 9 inches
Partially bound openings between 3.5 and 9 inches are considered entrapment hazards because a child's head can enter but not exit.
Question 3: When evaluating a protrusion hazard on a climbing structure, what minimum protrusion length triggers a hazard citation under CPSC guidelines?
- Greater than 0.5 inch (Correct answer)
- Greater than 1 inch
- Greater than 2 inches
- Greater than 3 inches
Correct answer: Greater than 0.5 inch
Protrusions extending more than 0.5 inch from a surface can catch clothing or body parts and are cited as hazards by CPSC guidelines.
Question 4: A slide exit has a triangular-shaped opening formed by the slide surface and a support rail. Which testing tool would a CPSI inspector use first to assess entrapment risk?
- The torso probe (Template B)
- The head entrapment probe (Template C) (Correct answer)
- A rigid ruler measuring the shortest side
- A flexible tape measure along the arc
Correct answer: The head entrapment probe (Template C)
The head entrapment probe (Template C) is applied first to determine whether a child's head could become entrapped in the triangular opening.
Question 5: An inspector finds a bolt end protruding 0.75 inch with a rounded cap. Should this be cited as a protrusion hazard?
- No, because the cap makes it safe regardless of length
- Yes, because any protrusion over 0.5 inch is a hazard (Correct answer)
- No, because only sharp protrusions are cited
- Yes, only if located within the fall zone
Correct answer: Yes, because any protrusion over 0.5 inch is a hazard
Any protrusion exceeding 0.5 inch is a hazard under CPSC guidelines regardless of whether it is capped or rounded.
Question 6: A fully bound opening in a deck railing measures 6 inches in diameter. What is the correct CPSI determination?
- Safe — fully bound openings are only hazardous above 9 inches
- Hazardous — falls within the head entrapment range of 3.5 to 9 inches (Correct answer)
- Safe — circular openings under 9 inches are always acceptable
- Hazardous — all openings above 4 inches must be cited
Correct answer: Hazardous — falls within the head entrapment range of 3.5 to 9 inches
Fully bound circular openings between 3.5 and 9 inches in diameter are head entrapment hazards because a child's head can enter but the neck cannot pass through.
Question 7: During a CPSI inspection, an inspector identifies a flexible rope net with openings that measure 8 inches when the net is slack. What is the correct next step?
- Cite immediately as a head entrapment hazard
- Test the openings under tension, as flexible structures are evaluated in their taut position (Correct answer)
- Disregard, because flexible materials cannot entrap a head
- Measure only when a child is actively using the net
Correct answer: Test the openings under tension, as flexible structures are evaluated in their taut position
Flexible structures like rope nets must be evaluated in their most restrictive (taut) position to accurately assess whether openings fall within the entrapment zone.
