FREE CPSI Layout and Site Design Requirements (Use Zones) Questions and Answers

Question 1

For a to-fro swing with a pivot point 8 feet above the surfacing, what is the minimum required use zone dimension in front of and behind the swing?

Accepted Answer

16 feet.

Answer

The use zone for a to-fro swing extends a minimum distance of twice the height (2 x H) of the pivot point in front of and behind the swing's at-rest position. In this case, 2 x 8 feet = 16 feet. This large, clear area is necessary to accommodate the full arc of the swing and prevent collisions.

Question 2

What is the minimum use zone required around a piece of stationary play equipment, such as a spring rider?

Accepted Answer

6 feet in all directions.

Answer

ASTM F1487 requires a minimum use zone of 6 feet (72 inches) in all directions from the perimeter of stationary equipment. This provides a clear space for children to circulate around the equipment and a safe fall zone if a child falls off.

Question 3

Under which condition is the overlapping of use zones generally NOT permitted?

Accepted Answer

Between the exit of a slide and the use zone of a swing.

Answer

The use zones for equipment with forced movement, such as swings, slides, and merry-go-rounds, should not overlap with each other or with the use zones of stationary equipment. The unpredictable nature of a user exiting a slide or swinging makes this overlap particularly hazardous.

Question 4

What is the minimum required length of the use zone at the exit of a slide?

Accepted Answer

6 feet from the end of the slide chute.

Answer

The use zone must extend a minimum of 6 feet (72 inches) from the end of the slide's exit chute. This provides adequate space for a child to exit the slide and move away before the next user comes down, preventing collisions and injuries.

Question 5

For a merry-go-round, how far must the use zone extend from its perimeter?

Accepted Answer

6 feet from the perimeter.

Answer

The use zone for rotating equipment like a merry-go-round must extend a minimum of 6 feet from the perimeter of the equipment. This space accounts for children who may fall or be thrown outward due to the rotational force.
