Free CPSI Core Knowledge Areas Questions and Answers — Questions and Answers
Question 1: What is the recommended maximum height for equipment intended for preschool-age children (2–5 years)?
- 10 feet
- 8 feet
- 6 feet (Correct answer)
- 5 feet
Correct answer: 6 feet
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?
- Sand
- Concrete
- Pea gravel
- Engineered wood fiber (Correct answer)
Correct answer: Engineered wood fiber
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?
- 6 inches
- 9 inches (Correct answer)
- 12 inches
- 15 inches
Correct answer: 9 inches
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?
- Less than 3 inches or greater than 9 inches
- Between 3.5 inches and 9 inches (Correct answer)
- 4 inches or larger
- No smaller than 7 inches
Correct answer: Between 3.5 inches and 9 inches
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?
- The area where playground staff are stationed for supervision.
- The ground-level area beneath and around playground equipment. (Correct answer)
- The space where children gather to play games.
- The designated seating area for parents and guardians.
Correct answer: The ground-level area beneath and around playground equipment.
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.
