Abstract

A liquid composition includes as a major component thereof a detergent mixture of linear alkylate sulfonate, non-ionic detergent and lauric superamide. Depending upon the particular use of the composition, it also includes effective amounts of other components. In use for fighting Class D (burning metal) fires, the composition includes alfalfa, vitamin B-6, sodium chloride, and bicarbonate of soda and the amount of water is minimized so that it is only enough to properly mix the other components together before they are added to the detergent mixture. When used for fighting Class A and B fires, the composition includes alfalfa, vitamin B-6, bicarbonate of soda, water, and optionally bovine urine. When used for extinguishing burning coal fires, the composition includes alfalfa, vitamin B-6, and water. When used as an oil dispersant, the liquid composition includes vitamin B-6, bicarbonate of soda, water, and lemon or lime juice. The application rate of liquid composition depends upon its particular use, for instance for extinguishing Class D fires it is applied at 100% concentration, and for fighting Class B fires it is applied at a dilution rate of about 0.5-6% with water.

Claims

1. A method of formulating a Class D firefighting agent which includes a detergent mixture comprising an alkylate sulfonate, non-ionic detergent and lauric superamide, comprising the steps of:

adding amounts of, vitamin B-6, sodium chloride and bicarbonate of soda effective when, in formulation, to put out a Class D fire, to a minimum amount of water sufficient to facilitate mixing of the components;

mixing the, vitamin B-6, sodium chloride, bicarbonate of soda, and water together so that substantially no lumps exist and a generally homogeneous slurry is provided; and

then

mixing the slurry with the detergent mixture so as to provide a homogeneous Class D firefighting agent.

2. A method of formulating a Class B firefighting agent by formulating a Class D firefighting agent as recited in claim 1;

and then

before application to a fire, diluting the firefighting agent with water at a dilution rate of about 0.5-2% agent to water.

3. A method of extinguishing a combustible metal fire comprising the step of:

applying directly to the fire a liquid composition comprising a major part of detergent mixture of linear alkylate sulfonate, non-ionic detergent and lauric superamide, and amounts of materials effective when, in formulation, to put out a combustible metal fire, for;

slowing down the detergent mixture and emulsification rate;

densifying and increasing the heat absorption capability of the detergent mixture;

agitating and stabilizing the detergent mixture; and

densifying and preventing separation and detonation of the detergent mixture when exposed to burning metal.

4. A method as recited in claim 13 wherein said applying step is accomplished by spraying the liquid composition, without significant water addition, directly onto the burning metal.

5. A method as recited in claim 4 wherein in the liquid composition the detergent mixture comprises about 39-67% of the total mass;

and wherein the other components consist essentially of;

alfalfa in an amount of about 3-7% by weight of the detergent mixture;

vitamin B-6 in an amount of 0.5-3% by weight of the detergent mixture;

sodium chloride in an amount of about 25-41% by weight of the detergent mixture; and

bicarbonate of soda in an amount of about 1-18% by weight of the detergent mixture;

with small amounts of non-toxic, relatively low flammability, coloring and perfuming agents as desired.

9. A method as recited in claim 4 wherein in the liquid composition the detergent mixture comprises about 39-67% of the total mass;

and wherein the other components consist essentially of;

vitamin B-6 in an amount of 0.5-3% by weight of the detergent mixture;

sodium chloride in an amount of about 25-41% by weight of the detergent mixture; and

bicarbonate of soda in an amount of about 1-18% by weight of the detergent mixture;

with small amounts of non-toxic, relatively low flammability, coloring and perfuming agents as desired.

6. A formulation for use as a Class D firefighting agent and comprising a mixture of:

a linear alkylate sulfonate, non-ionic detergent and lauric superamide detergent mixture comprising about 39-67 percent of the total mass of the formulation;

vitamin B-6 in the amount of 0.5-3 percent by weight of the detergent mixture;

sodium chloride in the amount of about 25-41 percent by weight of the detergent mixture;

bicarbonate of soda in the amount of about 1-18 percent by weight of the detergent mixture; and

a volume of water large enough only to provide effective mixing of the other components of the formulation and insufficiently large to interfere with the use of the formulation as an effective Class D firefighting agent.

7. A formulation as recited in claim 6 further comprising alfalfa in the amount of about 3-7% by weight of the detergent mixture.

8. A formulation for use as a Class B firefighting agent, for application with water at a dilution rate of about 0.5-2 percent to water, the mixture comprising:

a linear alkylate sulfonate, non-ionic detergent and lauric superamide detergent mixture comprising about 39-67 percent of the total mass of the formulation;

alfalfa in the amount of about 3-7 percent by weight of the detergent mixture;

vitamin B-6 in the amount of about 0.5-3 percent by weight of the detergent mixture;

sodium chloride in the amount of about 25-41 percent by weight of the detergent mixture; and

bicarbonate of soda comprising about 1-18 percent by weight of the detergent mixture.

10. A method of extinguishing a Class B fire comprising the steps of:

mixing with water a liquid composition comprising a detergent mixture of alkylate sulfonate, non-ionic detergent and lauric superamide, in an amount of about 39-67 percent of the total mass of the liquid composition;

alfalfa in the amount of about 3-7 percent by weight of the detergent mixture;

vitamin B-6 in an amount of 0.5-3 percent by weight of the detergent mixture;

sodium chloride in an amount of about 25-41 percent by weight of the detergent mixture; and

bicarbonate of soda in an amount of about 1-18 percent by weight of the detergent mixture;

adding the liquid composition to water at a dilution rate of about 0.5-2 percent to water; and

spraying the liquid composition and water directly onto a Class B fire.
