A forest fire retardant composition contains a retardant compound that includes a halide salt, a non-halide salt, a metal oxide, a metal hydroxide, a sulfate salt, or combinations thereof. The forest fire retardant composition may include at least one anhydrous salt and at least one hydrate salt. The sulfate salt may be magnesium sulfate. The magnesium sulfate hydrate has a formula MgSO.sub.4(H.sub.2O).sub.x, where x is about 1 to about 11. For example, x may be equal to at least one of 1, 2, 3, 4, 5, 6, 7, 9, 10 or 11. The composition may be in the form of a dry concentrate, a liquid concentrate, or a final diluted product. The final diluted product is effective in suppressing, retarding, and controlling forest fires while exhibiting corrosion resistance and low toxicity.

A multi-layer fire-resistance treatment (FRT) panel for use as structural sheathing. The wood structural panel may be OSB or plywood, coated or treated during the manufacturing process with a product that provides fire resistance. The treatment may be integrated with the material forming the wood structural panel, or may be a coating layer applied to the mat or mat layer. A burn-through layer also may be applied. A protective layer comprising a resin-impregnated paper overlay may be applied on one or both sides of the panel.
