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.
