Below lists the maximum height from which a child would not be expected to sustain a life-threatening
head injury in a fall on to four different loose-fill surfacing materials if they are installed and maintained at
depths of 150mm, 225mm and 300mm.
Fall height in millimeters from which a life-threatening head injury would not be expected
However, it should be recognized that all injuries due to falls cannot be prevented, no matter what surfacing
material is used.
It is recommended that a shock absorbing material extend a minimum of 1800mm in all directions from the
perimeter of stationary equipment such as climbing frames 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 twice the height of the pivot point measured from a point directly beneath the
pivot on the supporting structure.
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 the equipment in question. The choice of a material depends on the type
and height of the playground equipment, the availability of the material in a particular area, and its cost.
This information has been extracted from the CPSC publications “Playground Surfacing — Technical
Information Guide” and “Handbook for Public Playground Safety”.
