Entrapment and Protrusion Hazard Testing Flashcards

Which clothing-related entrapment hazard does CPSC specifically warn about on playground slides and climbing structures?

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.

When testing a flexible net or mesh structure for entrapment hazards, why is the standard rigid probe measurement potentially insufficient on its own?

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.

What is the CPSI's recommended action when an entrapment hazard is discovered during a routine inspection?

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.

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?

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.

Which of the following is NOT typically evaluated as part of an entrapment and protrusion hazard inspection under CPSI standards?

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.

During a CPSI inspection, how often should entrapment and protrusion hazard testing be performed as part of a comprehensive safety inspection?

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.

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?

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.
