A method of fighting a fire includes aerating a firefighting foam composition to form an areated firefighting foam; administering the aerated firefighting foam to a fire or applying the aerated firefighting foam to a surface of a volatile flammable liquid; wherein: the firefighting foam composition includes a sugar component that includes a monosaccharide sugar and/or a sugar alcohol; an anionic surfactant; a zwitterionic surfactant; an organic solvent including glycol ether and/or glycol solvent; a polysaccharide thickener; and at least about 40 wt. % water; wherein the composition is substantially free of any amine oxide or nonionic surfactants; and the composition is substantially free of fluorinated compounds.

A fire suppressant including technical urea 10-30% (by weight), ammonium sulphate 20-50%, and sodium bentonite 12-26%. The fire suppressant further includes polypropylene glycol (polyglycol), alkyl sulfonic acid, castor oil, guar gum, and/or triethanolamine dodecylbenzene sulfonate. The fire suppressant does not pose any risk to plant or animal life since the product is completely benign and is classified as non-toxic. It does not cause any damage to aquifers or groundwater, and it biodegrades in 30 to 60 days.

The present invention relates to a wetting extinguishing agent composition, comprising a metal carbonate; urea; a freezing point lowering agent; a fluorine-based surfactant; an amphoteric surfactant; and water, wherein the wetting extinguishing agent composition has excellent extinguishing ability not only for Class A fires, which are general fires, and Class B fires, which are oil-based fires, but also for Class K fires, which are kitchen fires.

A system includes an energy storage system (ESS), having battery pods and one or more battery cells disposed within the battery pods. The system also includes an ESS trailer, the ESS mounted on the ESS trailer. Also, the system includes a water spray subsystem. The water spray subsystem includes a plurality of sprinkler nozzles mounted within the battery pods and a first fluid connection fluidly connecting the sprinkler nozzles to a pump package. In addition, the water spray subsystem includes a second fluid connection, fluidly connecting the pump package to a water storage supply. The system includes a dry chemical spray subsystem, which has a dry chemical supply vessel, the dry chemical supply vessel mounted to the ESS trailer and a plurality of dry chemical distribution nozzles mounted within the battery pods, the dry chemical distribution nozzles fluidly connected to the dry chemical supply vessel by dry chemical distribution piping.

The present invention relates to a composition for extinguishing fire, comprising an aqueous solution of a surfactant and a deliquescent anionic salt. A method for extinguishing fire is also disclosed. The method (100) comprises mixing a surfactant and a deliquescent anionic salt in water to form an aqueous solution (110) and spreading the aqueous solution over a burning surface (120).

The fire-escape composition is composed of two components, one consisting essentially of urea, diammonium hydrogen phosphate, ammonium hydrogen carbonate, sodium bicarbonate, fluorocarbon surfactant and water; the other consisting of tartaric acid, potassium citrate and potassium dihydrogen phosphate, wherein the two components are combined before usage. The fire-escaping system comprises the fire-escape composition and a container with a chamber, wherein the container is to be applied to a fire so as to deliver the composition.

Provided is an aqueous fire extinguishing agent, and more particularly, an aqueous fire extinguishing agent which includes a non-electrolyte material, an anti-freezing agent, a silicone surfactant, and water and is adaptable to electrical fires. The aqueous fire extinguishing agent of the present invention is applicable to electrical fires and thus can effectively replace conventional powder fire extinguishers or gas-based fire extinguishers, and is eco-friendly in that it is harmless to the human body and the environment and does not cause secondary pollution due to powder or gas after use.

A forest fire retardant composition contains a retardant compound that includes a potassium salt. The potassium salt may include a potassium salt of an organic acid, a potassium salt of an inorganic acid, or mixtures thereof. The organic acid may include formic acid, acetic acid, propanoic acid, butanoic acid, lactic acid, oxalic acid, malic acid, gluconic acid, tartaric acid, uric acid, malic acid, or citric acid. The inorganic acid may include sulfuric acid, phosphoric acid, carbonic acid, or hydrochloric acid. 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.

An aqueous fire-fighting composition includes a surfactant component that includes an anionic surfactant, a zwitterionic surfactant, a nonionic surfactant, or a mixture of any two or more thereof; and a suspension agent comprising microfibrous cellulose. The suspension agent may include a water-soluble oligosaccharide and/or polysaccharide co-agent together with the microfibrous cellulose. The fire-fighting composition may also include one or more of a sugar component, organic solvent and a polysaccharide thickener, and be substantially free of fluorinated additives.

Firefighting compositions that may be used in onboard firefighting systems of heavy industrial equipment, such as heavy vehicles and other types of heavy equipment used in construction, forestry, mining, and other similar industries, are provided. The firefighting composition are aqueous liquids which include (a) a sodium and/or potassium salt of an organic acid; (b) one or more of an alkylpolyglycoside surfactant, an alkyl sulfate anionic surfactant, an alkyliminodialkylcarboxylate surfactant and a zwitterionic surfactant; (c) an acetylenic diol derivative surfactant and/or a siloxane-based surfactant; and (d) alkylene glycol and/or glycerol. Methods of producing a firefighting foam from the aqueous firefighting composition and using the aqueous firefighting composition to fight a fire, such as fighting a fire using an onboard industrial equipment firefighting system, are also provided.
