Read the first 7 Surfacing Requirements and Impact Attenuation Testing flashcards as text

  1. When performing a portable field Gmax test on loose-fill surfacing, how many drops are required at each test location according to ASTM F1292?

    Answer: Two drops, use the second result

    ASTM F1292 field testing protocol requires two drops at each location; the result from the second drop is used as the valid measurement.

  2. A playground has a composite structure with a highest accessible platform at 8 feet. What is the minimum required unobstructed surfacing zone extending from the structure's perimeter?

    Answer: 6 feet

    CPSC guidelines require a minimum 6-foot use zone extending from the perimeter of any play structure regardless of height.

  3. Which characteristic makes rubber tiles superior to loose-fill materials for playgrounds serving children with mobility impairments?

    Answer: Firm and stable surface allowing wheelchair access

    Rubber tiles provide a firm, stable, and slip-resistant surface that meets ADA accessibility requirements for wheeled mobility devices.

  4. At what minimum depth must engineered wood fiber (EWF) be installed to provide adequate fall protection for equipment with a fall height of 8 feet?

    Answer: 12 inches

    CPSC guidelines and ASTM F1292 testing data indicate that 12 inches of engineered wood fiber is required for fall heights up to 10 feet.

  5. A Gmax value is measured at 295 during a routine inspection of an in-use playground. What action is required?

    Answer: Immediately close the area and restore or replace surfacing

    A Gmax exceeding 200 g indicates the surfacing has failed to provide adequate impact attenuation and the area must be closed immediately until corrected.

  6. Which of the following loose-fill surfacing materials poses the greatest risk of becoming a health hazard if it retains moisture?

    Answer: Engineered wood fiber

    Engineered wood fiber can harbor mold, insects, and pathogens if it retains excessive moisture, requiring proper drainage and regular inspection.

  7. According to ASTM F1951, which test evaluates whether playground surfacing is accessible for children using mobility aids?

    Answer: Work of Propulsion test

    ASTM F1951 measures the Work of Propulsion required to traverse surfacing in a wheelchair, determining if it meets accessibility standards.
