FREE CPSI Surfacing Requirements and Impact Attenuation Testing Questions and Answers

Question 1

What does the 'critical height' of a playground surfacing material represent according to ASTM F1292?

Accepted Answer

The fall height below which a life-threatening head injury would not be expected to occur.

Answer

The maximum height a child can fall from without any injury.

Answer

The minimum required depth of the surfacing material.

Answer

The height at which the surfacing material was tested in the laboratory.

Question 2

During an impact attenuation test following ASTM F1292, what are the maximum allowable values for G-max and Head Injury Criterion (HIC)?

Accepted Answer

G-max of 200 and HIC of 1000

Answer

G-max of 100 and HIC of 500

Answer

G-max of 150 and HIC of 750

Answer

G-max of 250 and HIC of 1200

Question 3

For a stationary piece of equipment with a designated play surface 6 feet high, what is the minimum required extent of the protective surfacing in the use zone?

Accepted Answer

6 feet in all directions.

Answer

4 feet in all directions.

Answer

5 feet in all directions.

Answer

8 feet in all directions.

Question 4

An inspector notes that the engineered wood fiber (EWF) surfacing under a slide has been displaced, creating a 'dished out' area where the depth is only 4 inches, while the required maintained depth is 9 inches. What is the most appropriate action?

Accepted Answer

Recommend raking the existing EWF from other areas to restore the 9-inch depth and increase inspection frequency.

Answer

Close the entire playground until new surfacing can be installed.

Answer

Add 5 inches of sand on top of the EWF to bring it to the correct depth.

Answer

Measure the fall height of the slide to see if 4 inches is acceptable.

Question 5

ASTM F1292 requires impact attenuation testing to be performed at what temperature conditions?

Accepted Answer

At three different temperatures representing cold, ambient, and hot conditions.

Answer

Only at the ambient temperature on the day of the test.

Answer

Only in a controlled laboratory environment at 70°F (21°C).

Answer

At the coldest and hottest temperatures expected for the playground's geographic location.

Question 6

When inspecting a poured-in-place (PIP) rubber surface, what is a common hazard that can develop at the edges or seams?

Accepted Answer

The edges curl or separate from the substrate, creating a trip hazard.

Answer

The surface becomes too bouncy.

Answer

The color fades, creating an aesthetic issue.

Answer

The material releases a harmless but unpleasant odor.
