CPSI Entrapment and Protrusion Hazard Testing 2

Question 1

According to ASTM F1487, what is the minimum opening size that begins the head entrapment hazard zone?

Accepted Answer

3.5 inches (88.9 mm)

Answer

Openings between 3.5 inches and 9 inches are considered the head entrapment zone because a child's head can enter but may not exit.

Question 2

What is the upper boundary of the head entrapment hazard zone per ASTM F1487?

Accepted Answer

9.0 inches (228.6 mm)

Answer

Openings 9 inches or larger allow a child's head to pass through completely without entrapment, so they are outside the hazard zone.

Question 3

Which ASTM standard is the primary reference for public playground equipment safety requirements including entrapment hazards?

Accepted Answer

ASTM F1487

Answer

ASTM F1487 is the Standard Consumer Safety Performance Specification for Playground Equipment for Public Use.

Question 4

When testing an angled opening for head entrapment, the probe must be inserted at what angle relative to the opening?

Accepted Answer

In the most unfavorable angle that allows entry

Answer

Inspectors must test openings at the most unfavorable angle to simulate a child's worst-case head-first entry scenario.

Question 5

An upper-body entrapment hazard exists when a child's torso can enter an opening but cannot:

Accepted Answer

Exit or withdraw from the opening

Answer

Upper-body entrapment occurs when the torso enters but the child cannot reverse the entry due to body geometry differences between entry and exit.
