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 Specifi cation F1292. There are diff erent
types of surfacing to choose from; whichever product you select, follow
these guidelines:
Loose-fill Materials—Maintain a minimum depth of 23 cm (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 (244 cm) high;
and 23 cm (9 inches) of sand or pea gravel for equipment up to 152 cm (5
feet) high. NOTE: An initial fi ll level of 30 cm (12 inches) will compress to
about a 23 cm (9 inches) depth of surfacing over time. The surfacing will
also compact, displace, and settle, and should be periodically refi lled to
maintain at least a 23 cm (9 inches) depth.
Use a minimum of 15 cm (6 inches) of protective surfacing for play
equipment less than 122 cm (4 feet) in height. If maintained properly, this
should be adequate. (At depths less than 15 cm (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.
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 fi ll surfacing material. To
maintain the right amount of loose fi ll materials, mark the correct level
The maximum fall height for this product is 236,2 cm (93 in).
We recommend using a minimum depth of 23 cm (9 in) of wood mulch.

**Shredded/recycled rubber loose-fi ll surfacing does not compress in the same manner as other loose-fi ll materials. However, care should be
taken to maintain a constant depth as displacement may still occur. This information has been extracted from the CPSC publication "Public
Playground Safety Handbook". A copy of this publication can be obtained at www.cpsc.gov or calling the toll-free hotline: 1-800-638-2772.
Protective surfacing requirements can be found in ASTM F1292, Standard Specifi cation for Impact Attenuation of Surfacing Material within
the Use Zone of Playground Equipment. These standards can be ordered from ASTM International at www.astm.org.
on play equipment support posts. That way you can easily see when to
replenish and/or redistribute the surfacing.
Do not install loose-fi 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 fi ll
materials – like rubber tiles or poured-in-place surfaces.
Installation of these surfaces generally requires a professional and is not
a"do-it-yourself" project.
Review surface specifi 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 F1292 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.
Check the protective surfacing frequently for wear.
Placements—Proper placement and maintenance of protective surfacing is
essential. Be sure to:
Extend surfacing at least 2 m (6.6 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 2 m (6.6 feet) in all directions.
