Assignee:

FRS Group, LLC - Rocklin CA

International Classification:

A62D 1/00
A62C 3/02
C01F 5/40

Abstract:

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(HO), 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.

A62D 1/00

Abstract:

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.

Abstract:

A forest fire retardant composition is substantially free of ammonium and includes an organophosphate derived from (i) a phosphorylation agent and (ii) an organic molecule comprising at least two hydroxyl groups. The organophosphate may contain at least one phosphate ester bonded to an organic molecule, wherein the organic molecule comprises at least one monomer unit of about 2 to 40 carbon atoms. Preferably, at least 90% of the functional groups of the organophosphate is a phosphate ester group. The composition may also include a salt, including magnesium salt and/or calcium salt. The anion in the salt may be hydroxide, carbonate or phosphate. The salt may be an anhydrous salt, a salt hydrate, or a combination of both. The composition is effective in suppressing, retarding, and controlling forest fires while exhibiting corrosion resistance and low toxicity.
