Definitions
- the present invention relates to fire suppressing compositions and more particularly to detergent containing suppressant compositions which act as dispersants of oily and hydrocarbon liquids.
- the fire-suppressant detergent and dispersant composition of this invention is a combination of ingredients which produces a foam substance that will extinguish common combustibles and flammable liquid fires as a fire suppression agent.
- the foam substance reacts by covering the fire and flammable liquid surface, by providing a coating which prohibits vapor from being released by fuels, and inhibiting the oxygen supply to the fire.
- the formulation will resist being disrupted by flame, wind, thermal updraft and moat importently hydrocarbon attack.
- the foam system will flow around objects to cover areas which are difficult to reach and is capable of establishing a stable foam blanket which will re-seal itself when its surface is disrupted.
- the foam will achieve a cooling effect because of its water content around the foam bubbles along with its membrane as the substance is applied to heated metal surfaces.
- the foam bubbles retain the water content within the foam, making the formulation more adhesive and resistant to flashback due to deterioration from the fire or heat exposure,
- the low drainage and clingability on curved and vertical surfaces also adds to the favorable characteristics. If foam of this invention is applied to class "A" and to class "B" flammable liquid fires, it has a quick knock down, an exellent vapor seal and unique clingability characteristics.
- the formulation is helon and fluorocarbon free, non-corrosive, and performs equally well with fresh or sea water, The substance then reacts as a dispersant in a process of breaking down the properties of the fuels which it extinguishes.
- the formulation is a colloidal system which works by means of micelles, e.g. a submicroscopic aggregation of molecules such as a droplet in a colloidal system.
- the micelles repel each other in a ceaseless, random movement.
- the colloidal action penetrates into dirts, greases, or oils, each micelle occludes with a particle of the dirt or oil and the individual particles disperse and continue to repel each other so that they loose the ability to recoalesce or redeposit on the surface.
- the formulation penetrates any porous surface to reach any oily mass and breaks it down to smaller size particles, quickly, safely and with no damage to the environment.
- the biodegradable, non-toxic cleaner When used as a detergent, the biodegradable, non-toxic cleaner is applied like any other conventional cleaner, including power spray application, designed for a specific purpose application, and a specific concentrate or super concentrate ratio to water is applied prior to use.
- the detergent is antistatic and contains an antibacteriostat.
- the non-toxic, non-corrosive, non-abrasive, phosphate. ammonia and chloride free cleaner is applied with sponge, cloth or brush.
- the formulation When used as a biodegradable non-toxic oil and flammable liquid dispersant, the formulation is applied by conventional existing oil and flammable liquid spill equipment. The properties of the formulation allow it to be used for a wide variety of such applications.
- the formulation does not contain any caustic material.
- Fire suppressing compositions known in the fire fighting industry are generally divided into chemical foams and mechanical foams.
- the purpose of covering the fire surface by foam is to form a substantially homogenous mask of minute air in an aqueous foam which resist separation and rupture caused by winds, flame, etc;, which is capable of re-sealing itself, and which is liquid enough to flow around objects, reaching and covering areas, which might ignite, or which are on fire.
- the foam blanket ideally prevents oxygen supply to the combustion area, or in the case of a flammable liquid spill, covers the liquid preventing hazardous vapor production, as well as possible ignition of the flammable liquid.
- the benefits of the foam blanket can be attributed, in part, to the fact, that the foam has a high water content, and creates a cooling effect on heated surfaces.
- the amount of moisture contained within the foam is usually measured by the foam drainage time. Foams with a high moisture content drain at a faster rate then foams with a low moisture content.
- Mechanical foams are produced by aeration of an aqueous foam composition to cause entrapment of air in the aqueous phase thus forming the foam bubbles.
- Known mechanical foam systems contain proteins, fluoroproteins, synthetic detergents, aqueous film forming agents (AFFF), polyclycoside detergents, polysaccharide bipolymers, highly fluorinated surfactants, and pectins.
- Synthetic detergent foams are characterized by their significant expansion rate (approx. 20 to 1 as compared to 8 to 1 or 10 to 1 expansion ratios for protein or fluoroprotein foams).
- the synthetic detergent foam has good fluidity but low stability and rapid drainage time, as well as little radiant heat resistance and rapid dissipation.
- Synthetic detergent foam liquids comprise surfactants, foam stabilizers and freezing point depressants.
- the synthetic detergent foams do provide an insulating shield from the heat and allow fire fighters to breath and function, using a mask if necessary.
- Synthetic detergent foam combines the use of fluorocarbon surfactants and suitable foam stabilizers.
- Protein foam is primarely manufactured by alkaline or acid hydrolysis of either vegetable or animal proteins, including hydrolysed protein solutions of soybean, peanut, feather meal, hoof meal, horn meal, blood, or fish scales. Iron salts are always added to provide heat resistance and mechanical stability to the foam bubbles. Freezing point depressants and viscosity control agents are also incorporated.
- Protein foams contain various iron salts and other specialized ingredients which cause them to be both toxic and corrosive.
- Fluoroprotein foam combines the use of regular protein foam base with certain proprietary fluorinated surfactants to resist breakdown by dry chemical agents. Fluoroprotein film forming foam contains fluorocarbon surfactants,
- Aqueous film forming foams use both hydrolysed protein and fluorinated surfactant base plus stabilizing additives.
- United States Patent 4,594,167 discloses a foam fire extinguishing composition containing protein hydrolysate and a fluorine containing surfactant.
- United States Patent 4,713,182 discloses a fire suppressant foam composition containing citrus pectin and fluorine substituted thioether.
- United States Patent 5,207,932 discloses fire fighting foam which includes a polyglycoside to enhance perfluoroalkyl surfactants.
- United States Patent 5,061,383 discloses a detergent type mechanical foam containing surfactants derived from fatty acids.
- CA-A-1 337 011 discloses a liquid formulation for use as a Class "D" firefighting agent and which comprises a mixture of:
- AFFF aqueous film forming foams
- fluoroprotein foams contain fluorocarbon surfactants. These fluorocarbons will release gaseous halocarbon compounds that work to deplete the ozone layer and contribute to the "Greenhouse Effect".
- polysaccharide polymers The principal drawback of the use of polysaccharide polymers is the need to use high amounts of polysaccharide (between 1 and 2% in the foam concentrate) to obtain a foam having good extinguishing properties on polar solvent fires. This polymer concentration increases to a very high level the foam compound viscosity. The delivery of such a viscous foam is difficult, and becomes impossible below 5 degree celsius, even at the lowest polyester concentrations usable.
- AFFF aqueous film forming foam
- Fluoroprotein foam and aqueous film forming foam all contain fluorocarbon surfactants. These foams are both toxic, especially to marine life forms, and can cause corrosion to unpainted and unprotected metal surfaces, especially to aircraft engines. While these surfactants in themselves do not harm the ozone layer, they will release gaseous halocarbon compounds that do work to deplete the ozone layer and contribute to the " Greenhouse Effect ".
- Fire suppression agencies are not allowed to practice with them unless they have specialized containment and collection equipment and systems where runoff can be collected and treated. Even when collected, they are toxic to the bacteria within the collection and treatment system, and as a result most fire training schools test specific brands on their bacteria strains before they are allowed to be used in their training exercise.
- This invention relates in general to a biodegradable non-toxic fire foam, a biodegradable emulsifying oil and flammable liquid dispersant, and a biodegradable non-caustic, non-corrosive, non-abrasive, phosphate, chlorine and ammonia free, all purpose cleaning agent, and more particularly to a newly developed formulation of a homogenous blend of colloids, sterilants, bacteriostatics, sequesterants, surfactants, fatty acids, freezing point depressant and hyperwetting agents applied as a class "A" and "B" fire suppressant, oil and flammable liquid spill remediation dispersant, general oil and grease clean up agent, all purpose industrial and household cleaner.
- the fire suppressant foam of the present invention has positive qualities of a fluoroprotein or fluoropolysaccharide film forming foam while eliminating fluorocarbon for environmental reasons. It was found that 3 - 14% concentrations of the fire suppressant composition of this invention, converted mechanically into a water based foam, was effective as a fire suppressant although other concentrations would be used effectively depending on the type of fire.
- the invention includes a fire suppressant foam concentrate tailored for utilization on flammable liquid fires, capable of being used on hydrocarbon fires, or on polar solvent fires, and specifically formulated to meet the requirements of an international treaty signed in Montreal, Canada on September 16, 1987, known as the Montreal Protocol, to phase out halogenated fire supression agents.
- Alternate fatty acids for use in the composition include; coconut fatty acid, Ethofat, Kort Acid C60, Kort Acid C70 and Kort Acid G70.
- Useful surfactants include Cyclo 21, Cyclo 4221, Lauric Acid Diethanolamide, Linear Alkyl Sulfate Sodium Salt, Rhodapon SB-8208, Rhodaper ES, Rhodapex N70, Sodium Dioctyl Sulfosuccinate and Tergitol NP-9.
