  • Publication number: 20130112439
    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.

  • Patent number: 7533734
    Abstract: A fire suppression device characterized by a plunger that is extendible from a housing for delivery of a fire suppressant foam. The plunger may be equipped at its outer end with a puncture tip that can penetrate through the wall of a container or cargo cover for delivery of the fire suppressant foam directly to the cargo, preferably after full or almost full extension of the plunger. The plunger may be driven outwardly under high force by a pressurized gas that may also be used as a propellant for mixing with a liquid foaming agent, preferably within a foaming chamber carried by the piston. Provision may also be made for connection to a source of pressurized fluid to effect retraction of the plunger.

  • Patent number: 7530404
    Abstract: A system for a firefighting vehicle including a single compressor, driven by the engine of the firefighting vehicle, which generates a compressed fluid supply for operation of both the compressed air foam system and air brakes of the firefighting vehicle. The system can include a fluid storage tank that receives compressed fluid generated by the compressor. The storage tank can be in fluid communication with a dryer and a foaming system. The dryer dries a portion of the compressed fluid and supplies the dry fluid to one or more brake system tanks, which further provide a fluid supply to one or more air brakes of the vehicle to provide a braking force to stop the vehicle. An optionally undried portion of the fluid in the fluid storage tank can be in communication with a conduit which is further in communication with a foam supply and a liquid supply which mix with the compressed fluid to create a compressed fluid foam firefighting material.

  • Patent number: 7476346
    Abstract: The invention relates to compositions that prevent expansion of a fire, suppress existing fire, as well as methods of preparing and using such compositions. The composition is comprised of water, pseudo-plastic high yield suspending agent and starch. Compositions may contain additional functional agents, such as rheological, wetting, foaming, coloring, chelating, antimicrobial and stabilizing agents. In the description of the present invention, all composition modifications are referred to as compositions. The composition, an augmentation of water, exhibits the characteristics of a sag resistant aqueous gel in the tank, but has shear thinning capacity, allowing the composition to be pumped or sprayed as easily as water. At the point of impact, when the sprayed composition is again at rest, it instantly reverts to a sag resistant aqueous gel. The composition also forms an intumescent, surface char layer upon contacting a fire.

  • Publication number: 20080135263
    Abstract: A method of combining a first fluid from a first source (1) with a second fluid from a second source (16) in a de-sired ratio, by measuring the flow rate and pressure of the first fluid (at 12 and 14) prior to combining (at 10), and determining from this the desired flow rate and pressure at which the second fluid should be added to achieve the desired ratio. The pressure and flow rate of the second fluid is measured (at 6 and 8) and provides a feedback loop to ensure that the second fluid is being added at the desired flow rate and pressure to achieve the desired ratio. The pressure and flow rate of the second fluid may be controlled by multiple pumps 2 of different power.
