A forest fire retardant composition contains a retardant compound that includes a phosphate salt. The phosphate salt may include diammonium phosphate, diammonium orthophosphate, monoammonium phosphate, monoammonium orthophosphate, monosodium phosphate, disodium phosphate, disodium phosphate hydrate, sodium ammonium phosphate, sodium ammonium phosphate hydrate, sodium tripolyphosphate, trisodium phosphate, or dipotassium phosphate, and combinations thereof. The forest fire retardant composition may include an ammonium source. 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 fire extinguishing agent comprising a metallocene and a dispersion medium, the metallocene being dispersed in the dispersion medium.

A non-aqueous liquid concentrate includes starch, an acrylic acid homopolymer salt, vegetable oil, and clay. The non-aqueous liquid concentrate forms an aqueous dispersion when added to water and is capable of clinging to a surface.

The present application provides a method for preventing wildfire in a target, the method comprising providing an aqueous composition comprising fire retardant and fibrillar cellulose and applying the aqueous composition to the target. The present application also provides an aqueous composition comprising fire retardant and fibrillar cellulose, and a container comprising the aqueous composition. The present application also provides use of the aqueous composition for preventing wildfire.

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.

The forest fire retardant composition may include at least one anhydrous salt and at least one hydrate salt. The halide salt may be magnesium chloride, calcium chloride, or both. The magnesium chloride hydrate has a formula MgCl.sub.2(H.sub.2O).sub.x, wherein x is at least one of x=1, 2, 4, 6, 8, or 12. The calcium chloride hydrate has a formula CaCl.sub.2(H.sub.2O).sub.x, wherein x is at least one of 1, 2, 4, or 6. 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.

Disclosed is a fire suppressant material for controlling or extinguishing a combustion process, the fire suppressant material comprising zeolite particles with an internal porous structure, wherein molecules of a fire extinguishing substance are contained within the internal porous structure of the zeolite material.
