| 20080245538 | Automatic Stove Top Fire Extinguisher - A fire extinguishing system for use with gas or electric range stove top to automatically deploy and energize an audible alarm. The system includes a pressurized supply of inert gas within an inflatable bag. A grease fire on the stove top breaks the fusible cord and allows the case to open, releasing the inert gas supply. The inert gas inflates a flame resistant bag to cover the burners of the stove top. The bottom of the flame resistant bag is a specific temperature sensitive material that will decompose on contact with the grease fire. As the bottom decomposes, the flame resistant material surrounds the cooking container containing the grease fire. The grease fire becomes isolated by flame resistant materials and inert gas. The bottom two layers of the bag have an additional layer of non-flammable absorbent fiber between the two layers of the decomposing bottom. The decomposing bottom layer releases the non-flammable absorbent fiber into the cooking container containing the extinguished grease fire to absorb the cooking grease and prevent the cooking grease from re-igniting. | 10-09-2008 |
| 20090078433 | Method of Controlling Mine Fires with Polymeric Gel - A method is disclosed for controlling a mine fire by delivering a water-absorbent polymeric composition to a rock structure involved in a fire and infusing the polymeric composition into the rock structure.

| 20100243281 | Method for controlling and putting down woodland fires - The present invention relates to a method for controlling and putting down woodland fires, said method comprising the steps of collecting earth at a region encompassing the fire region and projecting the collected earth to the combustion region as well as adjoining regions thereof. | 09-30-2010 |
| 20120118591 | Water, foam and compressed air protection against fire, in or associated with structures - The method of suppressing fire in a structure, that includes providing a motor driven air compressor and water pump fixed position system operable to produce a pressurized source of fluid flow including water, foam and compressed air, installing an elongated duct or ducts to extend in fixed position or positions to a source fluid delivery location or locations at or within that structure, installing a fire or smoke detector or detectors at or within the structure, to produce a signal or signals in response to fire detection at or near the monitoring detector or detectors, and operating the system to deliver the fluid to the duct or ducts to be accurately and controllably delivered to a location or locations, in response to a detector signal or signals, for suppressing the fire, as via different nozzles to which fluid is controllably delivered. | 05-17-2012 |
| 20130269958 | FLUORINATED OXIRANES AS FIRE EXTINGUISHING COMPOSITIONS AND METHODS OF EXTINGUISHING FIRES THEREWITH - Fire extinguishing compositions and methods for extinguishing, controlling, or preventing fires are described wherein the extinguishing agent includes a fluorinated oxirane alone, or in admixture with a co-extinguishing agent selected from hydrofluorocarbons, hydrochlorofluorocarbons, perfluorocarbons, perfluoropolyethers, hydrofluoroethers, hydrofluoropolyethers, chlorofluorocarbons, bromofluorocarbons, bromochlorofluorocarbons, iodofluorocarbons, hydrobromofluorocarbons, fluorinated ketones, hydrobromocarbons, fluorinated olefins, hydrofluoroolefins, fluorinated sulfones, fluorinated vinylethers, and mixtures thereof. Also described are methods of preventing or extinguishing fires by introducing these compositions into an air-containing enclosed area and maintaining the composition in an amount sufficient to suppress combustion of combustible material in that enclosed area. | 10-17-2013 |
| 20140202720 | Method and Device for Suppressing Electrical Fires in Underground Conduit - A method and device for suppressing an electrical fire within an electrical wire carrying conduit. The device is a flexible receptacle containing an admixture of super absorbent polymer and water having substantially superior fire suppression and extinguishing properties that does not provide an electrically conductive environment. The receptacle is drawn though a conduit either before or after wires have been placed in the conduit, and the filled with the admixture. A sleeve may be placed over the receptacle to prevent breaching of the receptacle during installation. Once the receptacle and admixture is positioned within the conduit, should arcing or a buildup of heat occur, the receptacle will rupture and the admixture will cover the specific area. These particular properties and ratios of the admixture will enable electrical fires to be extinguished more rapidly and not flare back up. The admixture further encapsulates noxious and toxic gases associated with electrical fires. | 07-24-2014 |

A storage container includes a fire suppression agent and a first pressurized gas at least partially dissolved within the fire suppression agent. At least one canister contains a second pressurized gas. A piping system is configured to fluidly couple the at least one canister to the storage container and to fluidly couple the storage container to the at least one nozzle. When the fire suppression system is inactive, the fire suppression agent within the storage container is pressurized to a storage pressure. The storage pressure is greater than a vapor pressure of the fire suppression agent such that first pressurized gas dissolves into the fire suppression agent. When the fire suppression system is active, propellant pressure in the piping system exceeds the storage pressure of the fire suppression agent. | 03-03-2016 |
