Improvements in extinguishing fire

... 319,083. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). June 27, 1928. Chemicals.-A process of extinguishing fires, particularly of finely divided combustibles, consists in spraying on to the combustibles a dilute aqueous solution of a highly active wetting agent not in the form of a foam. Such wetting agents referred to include soaps or saponin, the sulphonation products of organic compounds, such as Turkey red oil or the mixtures produted by the sulphonation of mineral oils or tars or fractions thereof. One example consists of one to two parts of the sodium salt, of a nahthalene sulphonic acid, containing one or more propyl or butyl groups, in one hundred parts of water. For extinguishing fires in closed compartments, wet steam loaded with a wetted agent may be used. In a modification of the process, combustible matter is sprayed with the wetting agent so that, in case of fire, water which is then sprayed on will quickly penetrate the matter. Specification 289,630 is referred to.

Process for substantially suppressing phosgene-formation when extinguishing fires with carbon tetrachloride

... 319,320. I. G. Farbenindustrie Akt.- Ges. Sept. 20, 1928, [Convention date]. Chemicals. - The known process wherein ammonia and a hydrocarbon are added to carbon tetrachloride to suppress the formation of phosgene when the carbon tetrachloride is used for extinguishing fires is modified in that aryl or alkyl phosphates, or mixtures thereof, are added in place of the hydrocarbon. Alternatively, the phosphates may be added as well as the hydrocarbon. A very small amount of ammonia may be used, or sufficient to serve as a propelling agent for the extinguishing liquid. In the former case, compressed air or nitrogen may be used as the propelling agent. Amongst examples given of suitable additions to the carbon tetrachloride are the following : ammonia and three per cent of tricresylphosphate; ammonia, two per cent of petroleum, and one per cent of tricresylphosphate.

Flame Suppression Agent, System and Uses

Aqueous droplets encapsulated in a flame retardant polymer are useful in suppressing combustion. Upon exposure to a flame, the encapsulated aqueous droplets rupture and vaporize, removing heat and displacing oxygen to retard the combustion process. A polymer encapsulant, through decomposition, may further add free radicals to the combustion atmosphere, thereby further retarding the combustion process. The encapsulated aqueous droplets may be used as a replacement to halon, water mist, and dry powder flame suppression systems. In one embodiment of the invention, the aqueous droplets include a gelling agent, such as sodium alginate, and are encapsulated in an alginate-based material. 1. A method of suppressing a flame comprising:applying to the flame a flame suppression agent including an aqueous droplet containing water encapsulated in a non-toxic material, wherein said flame suppression agent is non-toxic and has a size of approximately 5-250 microns, andrupturing said flame suppression agent using said flame to release water from the aqueous droplet in the form of water vapor.2.

Use of a surfactant comprising at least one substituted or unsubstituted carbohydrate or carbohydrate derivative and at least one oligosilane as an addition to fire-extinguishing foams and/or concentrates. The present invention relates to the field of fire-extinguishing foams or foam concentrates.Particularly in fires of larger liquid amounts of organic chemicals such as fuels usually special foam concentrates are added to the extinguishing water. These have surfactant properties and in contrast to conventional fire-extinguishing foams enable the independent wetting of the surface of the burning material. Therefore, such so-called AFFF (Aqueous Film Forming Foams) extinguishing foams as a specific feature form a water film on the surface of the burning liquid. The thus resulting vapor barrier makes it difficult that the flammable liquid transits into the gas phase and thus maintains the fire or forms gas mixtures capable of ignition or explosion. The characteristic wettability of the AFFF foams also allows the foam to slide on the surface of the burning liquid, such that even positions are attained onto which the extinguishing foam cannot be applied directly. In addition, the foam surface closes self-dependently after disturbance (e.g. by falling objects). Furthermore, the film even flows and acts in areas which are not attained directly by foam.For a long time perfluorooctyl ...

Field of the InventionThe invention relates generally to firefighting products and methods and more particularly to fire and smoke prevention compositions and the processes of making them.2. Description of the Related ArtIn United States, a home fire occurs every 85 seconds. On average, and depending on the area and department, the fire department takes about 3-5 minutes to respond to a fire. In 2012, a total of 2,405 lives were lost in and a total of 13,175 injuries reported from residential fires. An estimated 50%-80% of fire deaths are from smoke inhalation. Too much smoke inhalation puts too much carbon monoxide into the lungs and could possibly cause brain damage because the carbon monoxide prohibits red blood cells from transferring oxygen into your body and carbon dioxide out of your body. On average, it would take 15 minutes of straight smoke, with no oxygen, to kill ...

BIODEGRADABLE FIRE-FIGHTING FORMULATION

A firefighting gel and uses thereof. 225-. (canceled)2747-. (canceled)4959-. (canceled) This application draws priority from U.S. Provisional Patent Application Ser. No. 61/417,227, filed Nov. 25, 2010, which application is incorporated by reference for all purposes as if fully set forth herein.The invention, in at least some aspects, relates to the field of fire-fighting formulations and methods, and more particularly, to ambiently degradable formulations and methods for fighting fires, particularly forest fires.Fire is the rapid oxidation of a material in the chemical process of combustion, releasing heat, light, and various reaction products. Fires start when a flammable and/or a combustible material, in combination with a sufficient quantity of an oxidizer such as oxygen gas or another oxygen-rich compound, is exposed to a source of heat or ambient temperature above the flash point for the fuel/oxidizer mix, and is able to sustain a rate of rapid oxidation that produces a chain reaction.Forest fires are uncontrolled fires occurring in combustible vegetation. A forest fire differ from other fires by its extensive size, the speed at which it can spread from its original source, its potential to change direction unexpectedly, and its ability to jump gaps such as roads and rivers.Water is currently the most frequently used fire-fighting medium. The extinguishing properties of water are based mainly on its effect in cooling the combustible material to a temperature below the ignition point of the material, by absorbing heat through conversion of water to water vapor.Use of water as an extinguishing agent has a number of disadvantages. For example, during the extinguishing process, large quantities evaporate or flow away unused and may cause unnecessary water damage.Use of water is particularly disadvantageous in fighting forest fires, because such fires are frequently preceded by a period of drought, and, accordingly, the ground has a particularly high water ...
