Steps
Identify the maximum fall height of the tallest equipment component in the use zone.
Reference the current CPSC Public Playground Safety Handbook's surfacing depth guidance (or an ASTM F1292-certified product's rated critical fall height) to pick a compliant material and depth.
Install loose-fill material at the recommended starting depth, accounting for expected compression over time.
Set a recurring schedule to measure and top off depth, since loose-fill materials compress with use and weathering.
Re-measure depth at multiple points across the use zone, not just the center, since displacement from digging and traffic is uneven.
Known gotchas
Loose-fill depth compresses meaningfully over time (materials like wood chips/mulch settle notably); compliant-at-installation does not mean compliant months later without top-offs.
Depth-to-fall-height figures vary by exact material (sand, pea gravel, wood mulch/chips, engineered wood fiber) — confirm current figures in the CPSC handbook table rather than a generic rule of thumb.
