Abstract:
A method of firefighting comprising:preparing a biodegradable, non-toxic foamable firefighting concentrate composition comprising, by volume, a mixture of 7 to about 45 parts of a 2 mole (EO) C12-C14 coconut amine, 7 to 45 parts of a 5 mole EO C12-C14 coconut amine, a C6 to C9 carboxylic acid in an amount effective to neutralized said tertiary amine to a pH within the range of from about 6.0 to about 8.0, from about 3 to about 20 parts of an alcohol, a compound having fluorescent properties in an amount effective to permit visualization or tracing of said concentrate composition in low light or no light conditions, and the remainder being water, such that 100 parts by volume are present in the entire composition; Injecting said concentrate composition into an aqueous stream intended for firefighting such that said stream includes said concentrates composition in an amount effective to permit said visualization or tracing; utilizing said stream to form an aqueous foam effective to provide fire resistance to a target; and directing said foam toward said target; wherein said foam is visible when exposed to light in the range of from about 200 to about 700 nanometers.
