Modern synthetic turf products are tested for fire safety using national standards. The most important is:
ASTM D2859 – The “Pill Test”
This test measures how turf reacts when exposed to a small ignition source (like a lit match or ember). For synthetic turf to pass, the flame must not spread more than one inch from the ignition point. Most premium turf products sold in California meet or exceed this standard.
In some situations—like turf installed on rooftops or near buildings—ASTM E108 (roofing fire test) may also apply, depending on local building codes.
What Makes Synthetic Turf Fire-Resistant?
In high-quality synthetic grass, fire resistance is built into the design:
- Non-flammable infill (such as silica sand) helps suppress flames.
- Polyethylene or polypropylene fibers melt rather than ignite.
- Fire-retardant additives are often included in the backing or fiber composition.
- Many products are self-extinguishing, meaning they stop burning once the heat source is removed.
When properly installed, synthetic turf will not fuel a fire, which makes it a safer alternative to dry vegetation in LA’s fire-prone neighborhoods.
