If you are responsible for a playground — whether at a school, park, daycare, HOA community, or your own backyard — you need to understand the safety standards for playground surfacing. Engineered wood fiber (commonly called playground chips) is one of the most popular and cost-effective options, but not all wood chips are suitable for playground use. Here is what you need to know.
What Makes Playground Chips Different from Regular Mulch?
Playground chips are not just garden mulch dumped in a play area. Genuine ASTM-certified playground chips are specifically engineered for child safety:
- Uniform size: Chips are processed to a specific size range that provides consistent cushioning. Pieces that are too large could cause trips; pieces too small compress and lose shock absorption.
- Clean material: No bark, leaves, twigs, dirt, or foreign objects. Only clean, processed wood.
- No toxic treatments: Made from untreated wood, free of CCA, creosote, and other chemical preservatives.
- Tested impact attenuation: The material is laboratory tested to verify it absorbs falls from specific heights when installed at the correct depth.
ASTM Standards for Playground Surfacing
The key standards you need to know:
ASTM F1292 — Impact Attenuation
This standard tests how well a surfacing material absorbs the impact of a fall. Playground chips must be tested at various depths and demonstrated to reduce head injury criteria (HIC) below 1,000 for the specified fall height.
ASTM F2075 — Engineered Wood Fiber
This standard specifically addresses engineered wood fiber for playground use. It covers material specifications, testing procedures, and quality requirements.
CPSC Guidelines
The U.S. Consumer Product Safety Commission publishes guidelines for public playground safety. These recommend minimum depths for loose-fill surfacing materials based on equipment fall height.
Required Depths for Playground Chips
Depth is critical. Too shallow and the material cannot adequately cushion a fall:
- Equipment up to 7 feet: Minimum 6 inches uncompressed depth
- Equipment up to 10 feet: Minimum 9 inches uncompressed depth
- Equipment up to 12 feet: Minimum 12 inches uncompressed depth
Important: These are uncompressed depths. Playground chips compact over time with use, so initial installation should be 20-25% deeper than the minimum. If your minimum is 9 inches, install at 11-12 inches.
Use Zones
Playground chips must extend beyond the equipment in all directions. CPSC guidelines specify:
- Stationary equipment (climbers, decks): Surfacing extends at least 6 feet in all directions from the equipment perimeter
- Swings: Surfacing extends in front and behind the swing to a distance equal to twice the pivot height
- Slides: Surfacing extends at least 6 feet from the exit of the slide
Where Playground Chips Are Used in South Florida
In the South Florida area, we supply certified playground chips for:
- Schools and daycares: Florida building code requires certified playground surfacing in licensed childcare facilities
- Public parks: Miami-Dade, Broward, and Palm Beach county parks departments maintain hundreds of playgrounds
- HOA communities: Community playgrounds in planned developments throughout South Florida
- Churches and community centers: Any organization with play equipment accessible to children
- Residential backyards: Homeowners with play structures for their children
Maintenance Requirements
Playground chips require regular maintenance to remain effective:
- Monthly raking: Redistribute material to maintain uniform depth, especially in high-use areas under swings and at slide exits
- Quarterly depth checks: Measure depth in multiple spots and add material where it has thinned
- Annual replenishment: Plan to add material annually to maintain required depth as chips decompose and compact
- Debris removal: Remove any foreign objects, trash, or organic debris that lands in the play area
- Drainage inspection: Ensure the area drains properly — standing water accelerates decomposition
Ordering Playground Chips in South Florida
Coco Garden Supply carries ASTM-certified playground chips in both bags for smaller projects and bulk quantities for large installations.
For commercial and institutional orders (schools, parks, HOAs), request a bulk quote with your project specifications. We can help calculate the correct quantity based on your play area dimensions and equipment heights.
For backyard installations, our bagged playground chips are available through our online shop with delivery across Miami-Dade, Broward, and Palm Beach counties.
