摘要： A method of fighting a fire includes aerating a firefighting foam composition to form an aerated 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; a surfactant component comprising an anionic surfactant, a zwitterionic surfactant, or a mixture of any two or more thereof; a polysaccharide thickener comprising succinoglycan; and at least about 30 wt. % water.

摘要： 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.

摘要： A method of proportioning a finished foam at or near a hazard comprising proportioning and delivering a first finished foam to the hazard, determining if the first finished foam extinguishes or suppresses the hazard, if not, selecting an amount of a fluorinated additive, and proportioning a foam solution including the selected amount of the fluorinated additive to form a fluorinated finished foam. A foam injection system is also disclosed.

摘要： An aqueous concentrate, which can be diluted with an aqueous diluent to form a foam precursor composition, is provided. The foam precursor composition may be aerated to form a firefighting foam. The present aqueous firefighting concentrates include a surfactant component, which includes one or more of an anionic surfactant, a zwitterionic surfactant and a nonionic surfactant and an aliphatic alcohol-based component. The aliphatic alcohol-based component typically includes at least two alcohols and/or alcohol ethoxylates. The aqueous concentrates contain a substantial amount of water and typically are substantially free of any fluorinated compound.
