COMMISSION’S OUTDOOR HOME PLAYGROUND SAFETY
HANDBOOK

X3.1 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 Specifi cation F 1292. There are
diff erent types of surfacing to choose from; whichever product
you select, follow these guidelines:

X3.1.1 Loose-Fill Materials:
X3.1.1.1 Maintain a minimum depth of 9 inches of loose-

fi ll materials such as wood mulch/chips, engineered wood fi 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 fi ll level of 12 inches will compress
to about a 9-inch depth of surfacing overtime. The surfacing will
also compact, displace, and settle, and should be periodically
refi lled to maintain at least a 9-inch depth.

X3.1.2 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.)

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
eff ectiveness. 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.

X3.1.3 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.

X3.1.3.1 Check and maintain the depth of the loose-

fi ll surfacing material. To maintain the right amount of loose-fi 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.

X3.1.3.2 Do not install loose-fi ll surfacing over hard

surfaces such as concrete or asphalt.

X3.1.4 Poured-In-Place Surfaces or Pre-Manufactured

Rubber Tiles — You may be interested in using surfacing other
than loose-fi ll materials – like rubber tiles or poured-in-place
surfaces.

X3.1.4.1 Installations of these surfaces generally require

a professional and are not “do-it-yourself” projects.

X3.1.4.2 Review surface specifi cation 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 Specifi cation for Impact
Attenuation of Surfacing Materials within the Use Zone of
Playground Equipment. This report should show the specifi 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

X3.1.4.3 Check the protective surfacing frequently for

wear.

X3.1.5 Placement — Proper placement and maintenance

of protective surfacing is essential. Be sure to:

X3.1.5.1 Extend surfacing at least 6 feet from the

equipment in all directions.

X3.1.5.2 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.
