Flammability – The materials utilized in recycling plastic lumber are flammable but not combustible, HDPE is difficult to ignite and the flame will normally self extinguish. Accepted extinguishing method: DRY CHEMICAL, CO2, WATER FOG/SPRAY, and FOAM. Emissions from combustion are carbon dioxide, carbon monoxide, H2O, nitrogen and organic vapors.
