Read the first 7 Entrapment and Protrusion Hazard Testing flashcards as text

  1. Openings in guardrails and platforms must be checked for entrapment hazards. Which location on a guardrail is most commonly cited for head entrapment during CPSI inspections?

    Answer: Openings between vertical balusters or rail members

    Vertical balusters or rail members frequently create openings in the 3.5–9 inch hazard zone, making them a primary entrapment concern on guardrails.

  2. A child's leg becomes trapped in a ladder rung opening. This is classified under which CPSI hazard category?

    Answer: Leg entrapment

    Leg entrapment is a distinct hazard category where a child's leg (particularly the foot and ankle) can become trapped in an opening.

  3. When inspecting a sliding pole, which entrapment risk does a CPSI inspector specifically evaluate?

    Answer: The gap between the pole and any surrounding structure or decking opening

    The opening around a sliding pole where it passes through a platform deck can be a head entrapment hazard if the gap falls in the 3.5–9 inch zone.

  4. A triangular opening is found in a climber structure. Under CPSI standards, this opening is considered hazardous if a 9-inch diameter probe can enter but the opening cannot accommodate which secondary test?

    Answer: A 9-inch diameter probe rotated 90 degrees

    For triangular and irregular openings, the entrapment probe must be tested in the most unfavorable orientation, including rotation, to assess true entrapment risk.

  5. Neck entrapment is MOST likely to occur in which type of playground structure opening?

    Answer: V-shaped or angled openings where a child's neck but not head can fit

    Neck entrapment occurs when an opening allows a child's neck to pass but the head is too large to follow, which is most common in V-shaped or angled openings.

  6. When a CPSI inspector tests openings near the top of climbing structures (at and above the 20-inch fall height threshold), what additional concern is prioritized?

    Answer: Fall through combined with entrapment leading to suspension-type injuries

    At elevated heights, entrapment combined with a fall can result in a child being suspended, making strangulation and crushing injury risks significantly higher.

  7. Which of the following platform edge conditions would a CPSI inspector flag as a potential entrapment concern?

    Answer: Openings between decking boards measuring 4 inches wide

    Openings between decking boards measuring between 3.5 and 9 inches fall within the head entrapment hazard zone and must be addressed.
