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. hospi
tal 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

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

another. However, each material is only effective when
properly maintained. Materials should be checked
periodically and replenished to maintain correct depth

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.
