Question 2

What does HIC stand for in the context of playground surfacing testing?

Accepted Answer

Head Injury Criterion

Answer

Hazard Identification Code

Answer

Height Impact Check

Answer

Hardness Index Coefficient

Question 3

According to CPSC guidelines, what minimum depth of engineered wood fiber (EWF) is required to provide fall protection at a fall height of 10 feet?

Accepted Answer

12 inches (30 cm)

Answer

6 inches (15 cm)

Answer

9 inches (23 cm)

Answer

It must be verified by field impact testing

Question 4

When testing surfacing in the field using the ASTM F3012 method, what condition of the surfacing should the inspector attempt to replicate?

Accepted Answer

The worst-case in-use conditions, including areas of maximum compaction and displacement

Answer

Brand new, freshly installed conditions

Answer

Average conditions across the entire use zone

Answer

Dry conditions only, since wet testing is not standardized

Question 5

What is the primary maintenance action required to keep loose-fill surfacing performing adequately over time?

Accepted Answer

Regular raking to redistribute displaced material and periodic replenishment to maintain depth

Answer

Adding chemical hardeners to prevent compaction

Answer

Covering the surface with a tarp when not in use

Answer

Replacing the entire surfacing annually

Question 6

Which factor is most likely to cause engineered wood fiber to FAIL an impact attenuation test unexpectedly?

Accepted Answer

Excessive moisture causing the material to clump and compact, reducing its shock-absorbing capability

Answer

The material being too light in color

Answer

The use zone being too large

Answer

Mixing EWF with pea gravel for aesthetic purposes
