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 Specication F 1292. There are different types of surfacing to choose from; whichever product you select, follow these guidelines:
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.
Loose-Fill Materials:

Maintain a minimum depth of 9 inches of loose- ll materials such as wood mulch/chips, engineered wood ber (EWF), or shredded/recycled
rubber mulch for equipment up to 8 feet high; and 9 inches of sand or pea gravel for equipment up to 5 feet high. NOTE: An initial ll level of
12 inches will compress to about a 9- inch depth of surfacing over time. The surfacing will also compact, displace, and settle, and should be
periodically relled to maintain at least a 9- inch depth.

Use a minimum of 6 inches of protective surfacing for play equipment less than 4 feet in height. If maintained properly, this should be
adequate. (At depths less than 6 inches, the protective material is too easily displaced or compacted.)

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. U.S Consumer Product Safety Commission, Washington, D.C., 20207 or call the toll-free hotline :[phone]

Check and maintain the depth of the loose-ll surfacing material. To maintain the right amount of loose-ll materials, mark the correct level on
play equipment support posts. That way you can easily see when to replenish and/or redistribute the surfacing.

Do not install loose ll 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-ll materials – like rubber tiles or poured-in-place surfaces.

Installations of these surfaces generally require a professional and are not "do-it-yourself" projects.

Review surface specications 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 F 1292 Standard Specication for Impact Attenuation of Surfacing Materials within the
Use Zone of Playground Equipment. This report should show the specic 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.
Placement
Proper placement and maintenance of protective surfacing is essential. Be sure to

Extend surfacing at least 6 feet 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 feet in all directions.
