Safety Surfacing Chart
Table – Critical heights (in feet) of Tested Materials
These directions are written based upon a depth of 12” of
resilient surfacing.
Do not forget to calculate the compressed resilient surfacing
depth needed and adjust your “dirt grade height” accordingly.
Chart taken from The Handbook for Public Playground Safety
written by the U.S. Consumer Product Safety Commission
(CPSC) page 5 (www.cpsc.gov).
