Abstract
A forest fire retardant composition includes a retardant compound that includes at least one anhydrous salt and at least one hydrate salt. The anhydrous salt is magnesium chloride, calcium chloride, or both. The hydrate salt is magnesium chloride, calcium chloride, or both. The magnesium chloride hydrate has a formula MgCl2(H2O)x, wherein x is at least one of 1, 2, 4, 6, 8, or 12. The calcium chloride hydrate has a formula CaCl2(H2O)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.
