Fire suppressant compositions which are substantially free of ammonium nitrate and which comprise potassium nitrate in an amount sufficient to generate at least about 10 wt. % potassium carbonate when combusted. Most preferably, a guanidine salt, such as guanidine nitrate, is used in combination with the potassium nitrate. The compositions employed in the present invention have low pressure exponents, high burning rates and low flame temperatures.

[ What is claimed is:] [1.]1. An ammonium nitrate-free fire suppressant composition consisting essentially of a fire suppressing effective amount of potassium nitrate and at least one guanidine salt selected from the group consisting of aminoguanidine nitrate, quanidine nitrate, triaminoguanidine nitrate, diaminoguanidine nitrate and ethylenebis(aminoguanidinium) dinitrate, said potassium nitrate and guanidine salt, said potassium nitrate and at least one guanidine salt being present in said composition in an amount sufficient to yield, on combustion, water vapor, inert combustion gases, and at least about 10 wt. % of potassium carbonate.
