Free CPSI Entrapment and Protrusion Hazard Testing Questions and Answers — Questions and Answers
Question 1: The small torso probe (3.5" x 6.2") is used to test a completely bounded, rigid opening. If this probe passes entirely through the opening, what is the immediate next step in the testing procedure?
- Test the opening with the fish probe.
- Test the opening with the large head probe (9.0"). (Correct answer)
- The opening is considered compliant and no further testing is needed.
- Measure the angle of the opening's interior surfaces.
Correct answer: Test the opening with the large head probe (9.0").
The testing sequence for a completely bounded, rigid opening is to first see if the small torso probe passes through. If it does, you must then test with the large head probe (9.0") to ensure a child's head can also pass through. If the large head probe is stopped, it signifies a head entrapment hazard.
Question 2: An inspector identifies an angle formed by two accessible adjacent surfaces on a play structure that is less than 55 degrees. What specific hazard does this condition present?
- A clothing toggle entrapment.
- A finger crush hazard.
- A head or neck entrapment. (Correct answer)
- A protrusion hazard.
Correct answer: A head or neck entrapment.
An angle of less than 55 degrees can create a V-shaped opening that could entrap a child's head or neck. This is a specific type of entrapment hazard that is identified by its angle rather than the standard head probes.
Question 3: The 'fish probe' is a specialized tool designed to simulate a child's finger and test for which type of hazard?
- Entrapment of the torso.
- Entanglement of clothing drawstrings. (Correct answer)
- Entrapment of the head.
- Protrusion hazards in the slide exit area.
Correct answer: Entanglement of clothing drawstrings.
The fish probe is used to test for potential entanglement hazards, particularly from clothing drawstrings. It is inserted into openings to determine if they can catch a drawstring toggle, which could lead to a strangulation hazard.
Question 4: When testing for protrusions on a moving component, such as a chain on a suspension bridge, which protrusion gauge should be used?
- The 3.5" diameter gauge.
- The 1.5" diameter gauge.
- The 0.5" diameter gauge. (Correct answer)
- The 0.12" thickness gauge.
Correct answer: The 0.5" diameter gauge.
Protrusions on moving components are tested with the smallest protrusion gauge, which has a 0.5" inside diameter. The movement of the equipment increases the risk of entanglement or injury from even small projections, necessitating a more stringent test.
Question 5: An inspector is testing a partially bounded opening, such as the space between a platform and an arched barrier. What is the correct sequence of tools to use for this test?
- The small torso probe, then the large head probe.
- The 'A' section of the head probe template, then the 'B' section. (Correct answer)
- The fish probe, then the toggle probe.
- The large head probe only.
Correct answer: The 'A' section of the head probe template, then the 'B' section.
Partially bounded openings are tested using the two-template head probe set. The 'A' section, representing the chin and front of the head, is inserted first, followed by an attempt to insert the 'B' section, representing the back of the head. If both templates can be inserted, it is a head entrapment hazard.
Question 6: The toggle test gauge is used to assess entanglement hazards primarily associated with what type of equipment?
- Enclosed tube slides.
- Climbers with rungs.
- Swings with chains.
- Slides, specifically at the top and along the bedway. (Correct answer)
Correct answer: Slides, specifically at the top and along the bedway.
The toggle test is specifically designed to check for entanglement hazards on slides. It is used to test any gaps or openings along the sliding surface, side rails, and exit area where a clothing toggle could become caught as a child slides down.
