Environmentally-clean fire inhibiting and extinguishing compositions and products for sorbing flammable liquids while inhibiting ignition and extinguishing fire
Environmentally-clean fire inhibiting and extinguishing dry powder compositions and products for sorbing flammable liquids while inhibiting ignition and extinguishing fire involving flammable hydrocarbon liquids such as, oils, fuels and non-polar solvents such as ketones and alcohols. The dry powder chemical compositions are made by mixing, blending and milling to suitable powder particle sizes, the following components: a fire extinguishing agent in the form of at least one alkali metal salt of a nonpolymeric saturated carboxylic acid; a powder fluidizing agent to help provide the dry powder composition with excellent fluid flow characteristics; and an oleophilic/hydrophobic composition for absorbing liquid hydrocarbons, while repelling water. A surfactant may be added to promote the formation of anhydrous semi-crystalline metal mineral salt film onto the surface of flammable hydrocarbon liquids involved in fire outbreaks to be extinguished and preferably absorbed by the dry powder chemical compositions.
1. Apparatus for dispensing environmentally-clean dry powder chemical material on flammable hydrocarbon liquid for absorbing the flammable hydrocarbon liquid, inhibiting fire ignition of the absorbed flammable hydrocarbon liquid and/or extinguishing an active fire involving the absorbed flammable hydrocarbon liquid, said apparatus comprising:
a container, storing a quantity of environmentally-clean dry powder chemical material, wherein said environmentally-clean dry powder chemical material consists of components comprising
a major amount of tripotassium citrate (TPC) powder,
a major amount of liquid hydrocarbon sorbent powder material having oleophilic/hydrophobic absorption properties, and
a minor amount of powder fluidizing agent for promoting said tripotassium citrate powder and liquid hydrocarbon sorbent powder material to flow like a fluid during application,
wherein each said component is mixed, blended and milled into said environmentally-clean dry powder chemical material stored in said container; and
an applicator in fluid communication with said container, for applying said environmentally-clean dry powder chemical material over flammable hydrocarbon liquid for absorbing the flammable hydrocarbon liquid, and inhibiting fire ignition of the flammable hydrocarbon liquid, and/or extinguishing an active fire involving the absorbed flammable hydrocarbon liquid.
2. The apparatus of claim 1 , wherein said applicator comprises a robot system for dispensing said environmentally-clean dry powder chemical material.
3. The apparatus of claim 1 , wherein said applicator comprises powered equipment for dispensing said environmentally-clean dry powder chemical material over flammable hydrocarbon liquid spilled into a body of water, or a ground surface.
4. The apparatus of claim 1 , wherein said applicator comprises a powered equipment for blowing said environmentally-clean dry powder chemical material over a distance and onto flammable hydrocarbon liquid that has been spilled (i) on the surface of a body of water, (ii) on a ground surface, or (iii) from a burning object such an automobile.
5. The apparatus of claim 1 wherein said applicator comprises a mobile vehicle for dispensing said environmentally-clean dry powder chemical material over said active fire.
6. The apparatus of claim 1 , wherein said applicator comprises a mobile backpack unit for dispensing said environmentally-clean dry powder chemical material over said active fire.
7. Apparatus for dispensing environmentally-clean fire inhibiting/extinguishing dry powder chemical material over Class A and/or Class B fuels, for inhibiting fire ignition of said Class A and/or Class B fuels, and extinguishing an active fire involving said Class A and/or Class B fuels-, said apparatus comprising:
a container, storing a quantity of environmentally-clean fire inhibiting/extinguishing dry powder chemical material, wherein said environmentally-clean fire inhibiting/extinguishing dry powder chemical material consists of components comprising
a major amount of tripotassium citrate (TPC) powder, and
a minor amount of powder fluidizing agent for promoting said tripotassium citrate powder to flow like a fluid during application,
wherein each said component is mixed, blended and milled into said environmentally-clean fire inhibiting/extinguishing dry powder chemical material stored in said container; and
an applicator in fluid communication with said container, for applying said environmentally-clean fire inhibiting/extinguishing dry powder chemical material over Class A and/or Class B fuels, for inhibiting fire ignition of said Class A and/or Class B fuels, and extinguishing an active fire involving said Class A and/or Class B fuels.
8. The apparatus of claim 7 wherein said applicator comprises a robot system for dispensing said environmentally clean fire inhibiting/extinguishing dry powder chemical material over flammable hydrocarbon liquid spilled into a body of water, or a ground surface.
9. The apparatus of claim 7 , wherein said applicator comprises powered equipment for dispensing said environmentally-clean fire inhibiting/extinguishing dry powder chemical material over flammable hydrocarbon liquid spilled into a body of water, or a ground surface.
10. The apparatus of claim 7 , wherein said applicator comprises a powered equipment for blowing said environmentally-clean fire inhibiting/extinguishing dry powder chemical material over a distance and onto flammable hydrocarbon liquid that has been spilled (i) on the surface of a body of water, (ii) on a ground surface, or (iii) from a burning object such an automobile.
11. The apparatus of claim 7 wherein said applicator comprises a mobile vehicle for dispensing said fire inhibiting/extinguishing dry powder chemical material over said active fire.
12. The apparatus of claim 7 , wherein said applicator comprises a mobile backpack unit for dispensing said fire inhibiting/extinguishing dry powder chemical material over said active fire.
