CPSI Surfacing Requirements and Impact Attenuation Testing 4

Question 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?

Accepted Answer

Two drops, use the second result

Answer

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

Question 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?

Accepted Answer

6 feet

Answer

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

Question 3

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

Accepted Answer

Firm and stable surface allowing wheelchair access

Answer

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

Question 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?

Accepted Answer

12 inches

Answer

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

Question 5

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

Accepted Answer

Immediately close the area and restore or replace surfacing

Answer

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