Free CPSI Core Knowledge Areas Questions and Answers

Question 1

What is the recommended maximum height for equipment intended for preschool-age children (2–5 years)?

Accepted Answer

6 feet

Answer

Safety standards for playgrounds, such as those from the CPSC and ASTM, recommend specific maximum heights for equipment based on age groups to minimize injury risk. For preschool-age children (2-5 years), a maximum fall height of 6 feet is recommended. This guideline ensures that potential falls result in less severe injuries, matching equipment design to children's developmental capabilities and risk tolerance.

Question 2

Which of the following surfaces provides adequate impact attenuation for playgrounds?

Accepted Answer

Engineered wood fiber

Answer

Adequate impact attenuation is crucial for playground surfacing to absorb the energy of a fall and reduce injury severity. Engineered wood fiber (EWF) is specifically designed and tested to meet these safety standards, providing a resilient and consistent surface. Unlike sand or pea gravel, EWF typically offers better compaction and drainage while maintaining its shock-absorbing properties, making it a superior choice for safety.

Question 3

What is the minimum required depth of loose-fill surfacing materials like mulch under playground equipment with a critical fall height of 8 feet?

Accepted Answer

9 inches

Answer

The required depth of loose-fill surfacing materials is directly related to the critical fall height of the equipment. For a critical fall height of 8 feet, safety standards like those from the CPSC recommend a minimum of 9 inches of loose-fill material, such as wood mulch, shredded tires, or pea gravel. This depth ensures sufficient impact absorption to prevent serious head injuries from falls.

Question 4

A gap in playground equipment is considered a potential entrapment hazard if it measures within which of the following ranges?

Accepted Answer

Between 3.5 inches and 9 inches

Answer

Gaps in playground equipment that fall within the range of 3.5 inches to 9 inches are considered head entrapment hazards for children. A gap smaller than 3.5 inches is too small for a child's head to enter, and a gap larger than 9 inches allows the head to pass through safely. Gaps within this specific range can allow a child's body to pass but trap their head, leading to strangulation or serious injury.

Question 5

Which of the following best describes a "use zone" in playground safety?

Accepted Answer

The ground-level area beneath and around playground equipment.

Answer

A 'use zone' is the designated safety area around and under playground equipment where a child might fall or exit from the equipment. This zone must be covered with appropriate impact-attenuating surfacing material and kept clear of obstacles. Its purpose is to provide a safe landing space and prevent collisions with other equipment or structures, ensuring children have adequate space to play safely.
