  • Patent number: 6645390
    Abstract: A biodegradable, non-toxic firefighting concentrate composition. The preferred compositions include 4 to 40 parts of a tertiary amine having 2-10 ethoxy or other solubilizing groups per mol selected from the group consisting of one or more of a series of similar homologs or isomers of C16-C18 animal-based tallow amines and coconut amines, 1 to 15 parts of a carboxylic acid having 6 to 16 carbon atoms or homolog thereof; 1 to 6 parts of a C6-C16 alcohol or homolog thereof and 0 to 10 parts of C4 and lower alcohols or homologs thereof, and enough water to create a total of 100 parts by volume. The concentrate is usually diluted up to 100 times (v/v) with water, and is also effective when mixed with foam-forming materials. In addition, the composition is useful with soil bacteria for remediating soil contaminated with hydrocarbon fuel and for facilitating fuel dispersion and degradation within bacterial-action sewage systems.

  • Patent number: 6296781
    Abstract: A novel composition for the control of fire is disclosed. The novel composition can be used as a fire extinguisher or as a fire retardant. The composition is prepared by the admixture of a preferred amount of a selected emollient, a preferred amount of a selected emulsifier, and a preferred amount of a selected dispersant in a water carrier. To the minimal mixture may be added a preferred amount of a selected oxygen competitor, a preferred amount of a selected coolant, a preferred amount of a selected radical scavenger, or a preferred amount of a selected oxygen depleting compound. In the most preferred embodiment all of the foregoing are admixed together in a water carrier. The resulting composition functions well as a fire extinguisher by extinguishing flame. It also acts as an effective fire retardant when applied to a flammable material as a prophylactic procedure.

  • Patent number: 6209655
    Abstract: An original method and products are described for fire quenching in all substrata such as forests, cultivated areas, city areas, industrial units, transport vehicles, etc. Aqueous suspensions of fire quenching special products contain endomolecularly water up to 300 g water/g of polymeric product, and the water is kept very strongly so that pressure is needed to take the water out. These products are used in quantities of 1-3%, and to the quenching water are added complimentary other products such as detergents, emulsifiers, adhesion promoters, and inorganic products such as carbonates, sulfates silicones etc. Quenching fires utilizes the solution containing these or a selection of these products, and the solution is thrown in the fire edges to rapidly extinguish the fires, because the water contained in the special organic products is liberated in the fire edges, where quenching immediately occurs.
