Environmentally-clean fire-inhibiting chemical compositions are used to biochemically treat wood furnish material and polymer resin binder material during composite wood product manufacture so that alkali metal (i.e. potassium) ions and/or micro-particles associated with the fire inhibiting biochemical treatment compositions are freely available throughout the entire composite wood product so as to inhibit fire ignition, flame spread, smoke development, as well as optionally, inhibit mold, mildew, microbial life and/or moisture. By embodying the environmentally-clean fire inhibiting biochemical compositions of the present invention into the lignocellulosic-based wood furnish material of a composite wood product, and preferably its polymeric resin binder material, during composite product manufacture, it is now possible to safely treat substantially the entire physical structure of the finished composite wood product and its structural components, with environmentally-clean fire inhibiting biochemical composition(s). By doing so, it is possible to provide the entire finished composite wood product with alkali metal ions and/or micro-particles thereof, that are freely available to inhibit fire ignition, flame spread and smoke development in accordance with ASTM Class-A fire-protected standards, as well as, optionally, inhibit metal corrosion, mold/mildew and moisture in a significantly new and improved manner.
