CPSI Specific Equipment Standards for Swings and Slides 2 — Questions and Answers
Question 1: According to ASTM F1487, what is the minimum use zone clearance in front of and behind a belt swing for children ages 5-12?
- 4 feet (1.2 m)
- 6 feet (1.8 m)
- Twice the height of the pivot point (Correct answer)
- The height of the pivot point plus 6 feet
Correct answer: Twice the height of the pivot point
ASTM F1487 requires the use zone in front of and behind a swing to extend a minimum distance equal to twice the height of the pivot point from directly below it.
The use zone for swings extends in the direction of travel a distance equal to twice the pivot height both in front of and behind the swing seat. This accounts for the arc of travel and the trajectory of a child who might fall or jump from the swing. This requirement often results in large use zones that must be factored into playground layout design.
Question 2: What type of swing seat is specifically prohibited on tot-lot equipment intended for children ages 2-5 under ASTM F1487?
- Belt seats
- Full-bucket seats
- Animal-figure swings (Correct answer)
- Tire swings
Correct answer: Animal-figure swings
Animal-figure swings (also called 'fun' or 'novelty' swings) with rigid animal shapes are prohibited on equipment intended for children ages 2-5 because they present significant impact hazard to other children.
Animal-figure swings have rigid frames that can strike other children in the head with serious force if a child walks into the swing's path. ASTM F1487 restricts these swings because young children ages 2-5 lack the awareness to avoid moving swings. Acceptable seat types for this age group include full-bucket seats and belt seats, which are flexible and lower-impact.
Question 3: ASTM F1487 specifies that the angle of a slide chute relative to the horizontal should not exceed what maximum value for traditional straight slides?
- 20 degrees
- 30 degrees
- 35 degrees (Correct answer)
- 45 degrees
Correct answer: 35 degrees
ASTM F1487 specifies that the angle of a traditional slide chute should not exceed 35 degrees from the horizontal to prevent children from gaining excessive speed during descent.
A slide angle exceeding 35 degrees allows children to reach speeds at the exit that may cause them to be projected forward and land well beyond the slide exit, potentially outside the use zone. The 35-degree limit balances play value with controlled exit speed. Tube and roller slides may have different specifications but must still manage exit velocity.
Question 4: What is the required minimum overhead clearance for a slide exit?
- 16 inches (400 mm) (Correct answer)
- 7 feet (2.1 m)
- It depends on the slide height
- No minimum is specified by ASTM F1487
Correct answer: 16 inches (400 mm)
ASTM F1487 requires a minimum of 16 inches (400 mm) of clearance between the bottom of the slide exit and the protective surfacing to allow for adequate landing space.
The 16-inch minimum exit clearance ensures that children can complete their slide exit without hitting the ground surface while still in the sliding position. The slide exit must also transition to a landing area with protective surfacing meeting ASTM F1292 requirements. Inspectors verify both the clearance measurement and the condition of the exit landing zone.
Question 5: Which of the following is a key safety requirement for swing hangers under ASTM F1487?
- Swing hangers must be painted a bright color for visibility
- Swing hangers must allow independent movement of adjacent swings to prevent entanglement (Correct answer)
- Two swings must share a single hanger for stability
- Hangers must be made of stainless steel only
Correct answer: Swing hangers must allow independent movement of adjacent swings to prevent entanglement
ASTM F1487 requires that swing hangers allow each swing to move independently of adjacent swings, preventing entanglement and chain-wrapping hazards.
Independent swing hanger movement prevents the chains or ropes of adjacent swings from intertwining, which can create entanglement and strangulation hazards, particularly for younger children. Additionally, hangers should be designed to close around the swing suspension to prevent the swing from being lifted off the hanger, which could create a hook-type entrapment hazard.
Question 6: For a composite play structure containing a slide, where is the use zone for the slide measured from?
- From the base of the tallest platform on the structure
- From the slide exit, extending a minimum distance in the direction of the slide's travel (Correct answer)
- From the perimeter of the entire composite structure
- From the slide entrance at the top
Correct answer: From the slide exit, extending a minimum distance in the direction of the slide's travel
The use zone for a slide extends from the slide exit in the direction of travel — typically 6 feet (1.8 m) beyond the exit point — and must be covered with protective surfacing meeting ASTM F1292.
The slide use zone is specifically oriented in the direction of travel from the exit point. ASTM F1487 requires at least 6 feet of clearance beyond the slide exit. This zone must overlap with the general use zone of the composite structure and must have adequate protective surfacing depth rated for the slide's critical fall height. Inspectors must verify both dimensions and surfacing condition.
