Free CPSI Entrapment and Protrusion Hazard Testing 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?

Accepted Answer

Test the opening with the large head probe (9.0").

Answer

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?

Accepted Answer

A head or neck entrapment.

Answer

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?

Accepted Answer

Entanglement of clothing drawstrings.

Answer

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?

Accepted Answer

The 0.5" diameter gauge.

Answer

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?

Accepted Answer

The 'A' section of the head probe template, then the 'B' section.

Answer

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.
