Information on Playground Surfacing Materials:

Commission's Information Sheet for playground surfacing material Also

X3. CONSUMER INFORMATION SHEET FOR PLAYGROUND SURFACING MATERIALS
X3.1 The U.S. Consumer Product Safety Commission (CPSC) estimates that about 100,000
playground equipment-related injuries resulting from falls to the ground surface are treated
annually in U.S. hospital emergency rooms. Injuries involving this hazard pattern tend to be
among the most serious of all playground injuries, and have the potential to be fatal, particularly
when the injury is to the head. The surface under and around playground equipment can be a
major factor in determining the injury-causing potential of a fall. It is self evident that a fall onto a
shock-absorbing surface is less likely to cause a serious injury than a fall onto a hard surface.
Playground equipment should never be placed on hard surfaces such as concrete or asphalt
and while grass may appear to be acceptable it may quickly turn to hard packed earth in areas
of high traffic. Shredded bark mulch, wood chips, fine sand or find gravel are considered to be
acceptable shock absorbing surfaces when installed and maintained at a sufficient depth under
and around playground equipment.
X3.2 Table X3.1 lists the maximum height from which a child would not be expected to sustain a
life-threatening head injury in a fall onto four different loose-fill surfacing materials if they are
installed and maintained at depths of 6, 9, and 12 in. However, it should be recognized that all
injuries due to falls cannot be prevented no matter what surfacing material is used.
X3.3 It is recommended that a shock absorbing material should extend a minimum of 6 ft in all
directions from the perimeter of stationary equipment such as climbers and slides. However,
because children may deliberately jump from a moving swing, the shock absorbing material
should extend in the front and rear of a swing a minimum distance of 2 times the height of the
pivot point measured from a point directly beneath the pivot on the supporting structure.
X3.4 This information is intended to assist in comparing the relative shock-absorbing properties
of various materials. No particular material is recommended over another. However, each
material is only effective when properly maintained. Materials should be checked periodically
and replenished to maintain correct depth as determined necessary for your equipment. The
choice of a material depends on the type and height of the playground equipment, the
availability of the material in your area, and its cost.
