  • Patent number: 9216308
    Abstract: A unique method for suppressing the spread of and extinguishing underground electrical fires in confined areas such as tunnels and conduits. A super absorbent polymer is mixed with water to form a hydrated super absorbent polymer and this admixture is applied to an electrical fire. The admixture has superior fire suppression and extinguishing properties than the fire suppression and extinguishing properties of plain water. The admixture has the ability to cling to the object(s) to which it has been applied and both cool down the object(s) and block the fire from reaching the object(s). The super absorbent polymer and water admixture also encapsulates the noxious and toxic gases produced by electrical fires and prevents the release of these toxic gases into the atmosphere. Finally, the super absorbent polymer and water mixture retains the ash, particulates, and other byproducts of the electrical fire to enable a thorough cleanup.

  • Publication number: 20140183400
    Abstract: Disclosed is a fire extinguishing composition of copper salts, which comprises a compound of copper salts and a fire retardant component with the content of 30 wt %--95 wt % for the former and 5 wt %-70 wt % for the latter respectively. A pyrotechnic agent in the composition serves as heat source and power source, and through being ignited, the pyrotechnic agent is burnt to generate high temperature to enable the composition to perform decomposition reaction so that a large quantity of the resulting fire extinguishing substances can be spouted out with the pyrotechnic agent to achieve an object of fire extinguishing. The fire extinguishing composition of copper salts can decrease the quantity of heat released by combustion of the pyrotechnic agent rapidly and efficiently, thus greatly reducing the nozzle temperature of a fire extinguishing apparatus and a sprayed substance, avoiding use of a complicated cooling system of the fire extinguishing apparatus, and also eliminating the danger of a secondary fire.

  • Publication number: 20140183399
    Abstract: The disclosure relates to a fire-extinguishing composition comprising an organic acid compound, wherein the fire-extinguishing composition comprises an organic acid compound. The content of the organic acid compound is 50% by mass or more, and preferably 70% to 90% by mass. The organic acid compound according to the disclosure may absorb heat and be decomposed at a high temperature, and release a fire-extinguishing substance. The fire-extinguishing substance may react, by means of free radicals, with one or more of O., OH., H. free radicals that are necessary for chemical-looping combustion, thus cutting off the chemical-looping combustion, or may reduce the oxygen partial pressure by physical action to inhibit the flame, or achieve the fire-extinguishing effect by both the physical and chemical inhibition effects.

  • Patent number: 8757280
    Abstract: A unique method for suppressing the spread of and extinguishing underground electrical fires in confined areas such as tunnels and conduits. A super absorbent polymer is mixed with water to form a hydrated super absorbent polymer and this admixture is applied to an electrical fire. The admixture has superior fire suppression and extinguishing properties than the fire suppression and extinguishing properties of plain water. The admixture has the ability to cling to the object(s) to which it has been applied and both cool down the object(s) and block the fire from reaching the object(s). The super absorbent polymer and water admixture also encapsulates the noxious and toxic gases produced by electrical fires and prevents the release of these toxic gases into the atmosphere. Finally, the super absorbent polymer and water mixture retains the ash, particulates, and other byproducts of the electrical fire to enable a thorough cleanup.

  • Publication number: 20140138105
    Abstract: An aqueous fire sprinkler fluid containing low carbon number carboxylate salts for freezing point depression is described. The salts may be used in conjunction with glycols. The salts decrease the combustibility of the glycol containing fluids and give lower viscosity than higher glycol fluids, both benefitting fire sprinkler systems. These salt solutions are friendly to metal and CPVC pipes and are thus useful for fire sprinkler systems by not causing environmental stress cracking of the CPVC components and not being corrosive to the metal parts.

  • Patent number: 8715540
    Abstract: The present invention provides combined property, dual-action aqueous and dry compositions for application to a material, such as conventional Gypsum Wall Board, ceiling tiles, joint compounds, concrete and other interior building materials, prior to an exposure of the material to fire, or prior to, during or after exposure of the material to conditions favorable to the growth of microbes, and related methods. When compositions within the present invention are properly applied to a material prior to the material being exposed to fire, or prior to, during or after the material being exposed to conditions favorable to the growth of microbes, these compositions have the effect of reducing the amount of burning that occurs to the material, and/or reducing the amount or density of smoke and associated toxic gases produced by the material, when the material is exposed to fire.
