CONSUMER INFORMATION SHEET FOR PLAYGROUND SURFACING MATERIALS*
Select Protective Surfacing—One of the most important things you can
do
to reduce the likelihood of serious head injuries is to install shock-absorbing
protective surfacing under and around your play equipment. The protective
surfacing should be applied to a depth that is suitable for the equipment height in
accordance with ASTM Specification F1292. There are different types of surfacing
to choose from; whichever product you select, follow these guidelines:
Loose Fill Materials—Maintain a minimum depth of 9 inches (23 cm)of loose fill
materials such as wood mulch/chips, engineered wood fiber (EWF), or shredded/
recycled rubber mulch for equipment up to 8 feet (244 cm) high; and 9 inches
(23 cm) of sand or pea gravel for equipment up to 5 feet (152 cm) high. NOTE: An
initial fill level of 12 inches (30 cm) will compress to about a 9 inch (23 cs) depth
of surfacing over time. The surfacing will also compact, displace, and settle, and
should be periodically refilled to maintain at least a 9 inch (23 sm) depth.
Use a minimum of 6 inches (15 cm) of protective surfacing for play equipment less
than 4 feet (122 cm) in height. If maintained properly, this should be adequate. (At
depths less than 6 inches (15 cm), the protective material is too easily displaced or
compacted.)
NOTE: Do not install home playground equipment over
concrete, asphalt, or any other hard surface. A fall onto a hard surface can
result in serious injury to the equipment user. Grass and dirt are not considered
protective surfacing because wear and environmental factors can reduce their
shock-absorbing effectiveness. Carpeting and thin mats are generally not adequate
protective surfacing. Ground level equipment – such as a sandbox, activity wall,
playhouse or other equipment that has no elevated play surface – does not need
any protective surfacing.
Use containment, such as digging out around the perimeter and/or lining the
perimeter with landscape edging. Don't forget to account for water drainage.
Check and maintain the depth of the loose fill surfacing material. To
maintain the right amount of loose fill materials, mark the correct level on play
equipment support posts. That way you can easily see when to replenish and/or
redistribute the surfacing.
**The maximum fall height for this product is 63 5/16 in (161 cm).
We recommend using 6 in (15 cm) of Double Shredded Bark Mulch.**

***This data is from tests conducted by independent testing laboratories on a 6-inch depth of uncompressed shredded tire
samples produced by four manufacturers. It is recommended that persons seeking to install shredded tires as a protective surface
request test data from the supplier showing the critical height of the material when it was tested in accordance with ASTM F1292.
Do not install loose fill surfacing over hard surfaces such as concrete or asphalt.
Poured-In-Place surfaces or Pre-manufactured
Rubber Tiles—You may be interested in using surfacing other than loose fill
materials – like rubber tiles or poured-in-place surfaces.
Installation of these surfaces generally requires a professional and are not a"do-it-
yourself" project.
Review surface specifications before purchasing this type of surfacing. Ask the
installer/manufacturer for a report showing that the product has been tested to
the following safety standard: ASTM F1292 Standard Specification for Impact
Attenuation of Surfacing Materials within the Use Zone of Playground Equipment.
This report should show the specific height for which the surface is intended to
protect against serious head injury. This height should be equal to or greater than
the fall height – vertical distance between a designated play surface (elevated
surface for standing, sitting, or climbing) and the protective surfacing below – of your
play equipment.
Check the protective surfacing frequently for wear.
Placements—Proper placement and maintenance of protective surfacing is
essential. Be sure to:
Extend surfacing at least 6.6 feet (2 m) from the equipment in all directions.
For to-fro swings, extend protective surfacing in front of and behind the swing
to a distance equal to twice the height of the top bar from which the swing is
suspended.
For tire swings, extend surfacing in a circle whose radius is equal to the height of the
suspending chain or rope, plus 6.6 feet (2 m) in all directions.
