CPSI Entrapment and Protrusion Hazard Testing 5 — Questions and Answers
Question 1: Which clothing-related entrapment hazard does CPSC specifically warn about on playground slides and climbing structures?
- Shoe laces longer than 12 inches
- Drawstrings and hood strings on children's outerwear (Correct answer)
- Belt loops on pants
- Velcro closures on footwear
Correct answer: Drawstrings and hood strings on children's outerwear
Drawstrings and hood strings on children's clothing can catch on equipment protrusions and create strangulation hazards on slides and climbers.
Question 2: When testing a flexible net or mesh structure for entrapment hazards, why is the standard rigid probe measurement potentially insufficient on its own?
- Flexible materials are exempt from entrapment standards
- The mesh may stretch or deform under a child's weight, creating larger openings than measured when unloaded (Correct answer)
- Flexible nets cannot create head entrapment hazards
- Rigid probes are only used for metal structures
Correct answer: The mesh may stretch or deform under a child's weight, creating larger openings than measured when unloaded
Flexible and mesh materials can deform under load, potentially increasing opening sizes beyond what the unloaded inspection reveals.
Question 3: What is the CPSI's recommended action when an entrapment hazard is discovered during a routine inspection?
- Document the hazard and schedule repair within 30 days
- Post a warning sign near the hazardous area and continue monitoring
- Remove the equipment from service immediately until the hazard is corrected (Correct answer)
- Restrict access to children under age 5 only
Correct answer: Remove the equipment from service immediately until the hazard is corrected
Entrapment hazards are considered serious safety defects requiring immediate removal from service until corrected, not deferred repair.
Question 4: A compound-angle opening (one that is angled both horizontally and vertically) is found on a climber. How should the CPSI inspector evaluate this for entrapment?
- Only test the horizontal angle since vertical angles are self-draining
- Test only at the steepest angle encountered
- Test at multiple orientations to find the most unfavorable entry angle (Correct answer)
- Exclude compound-angle openings from entrapment testing as they are not addressed by ASTM F1487
Correct answer: Test at multiple orientations to find the most unfavorable entry angle
ASTM F1487 requires testing at the most unfavorable angle, and compound openings require multiple orientations to determine the worst-case entrapment scenario.
Question 5: Which of the following is NOT typically evaluated as part of an entrapment and protrusion hazard inspection under CPSI standards?
- Openings in climber handholds and footholds
- The color of the playground equipment finish (Correct answer)
- Gaps between platform boards
- Protrusion of hardware above the equipment surface
Correct answer: The color of the playground equipment finish
Equipment color is a maintenance and aesthetic consideration, not a factor in entrapment or protrusion hazard assessments under CPSI or ASTM standards.
Question 6: During a CPSI inspection, how often should entrapment and protrusion hazard testing be performed as part of a comprehensive safety inspection?
- Daily as part of operational checks
- Monthly as part of routine maintenance inspections
- Annually as part of a comprehensive or high-level inspection (Correct answer)
- Only after a reported injury incident
Correct answer: Annually as part of a comprehensive or high-level inspection
Comprehensive entrapment and protrusion testing is part of the annual high-level inspection, while routine checks focus on quick visual and functional items.
Question 7: A CPSI inspector finds a guardrail baluster spacing that passes the 3.5-inch minimum test but fails when tested with the 9-inch headform probe in an angled entry. What does this finding indicate?
- The opening is safe because it passed the 3.5-inch test
- The opening is within the head entrapment zone and must be corrected (Correct answer)
- Only the 3.5-inch probe test result is valid for compliance
- The 9-inch probe test is optional for baluster spacing
Correct answer: The opening is within the head entrapment zone and must be corrected
If the 9-inch probe can enter an opening (regardless of angle), the opening falls within the entrapment zone and must be corrected to remove the hazard.
