Provided are novel compositions for producing foam comprising a water-soluble polymer that is capable of self-hydrating. The present invention is also directed to methods for producing foam from compositions comprising a water-soluble polymer that is capable of self-hydrating.

The present invention relates to compositions for use in refrigeration, air-conditioning, and heat pump systems wherein the composition comprises a fluoroolefin and at least one other component. The compositions of the present invention are useful in processes for producing cooling or heat, as heat transfer fluids, foam blowing agents, aerosol propellants, and fire suppression and fire extinguishing agents.

Aqueous film forming firefighting composition concentrates are provided that contain an effective amount of a monomelic zwitterionic or anionic C.sub.6 perfluoroalkyl surfactant having a molecule weight less than 800 daltons. The compositions also contain an effective amount of a foam stabilizing agent, and an effective amount of at least one non-fluorinated surfactant. The composition has less than 0.8% F, and is substantially free of any surfactant containing a perfluoroalkyl group containing more than 6 carbon atoms. The composition meets Military Specification MIL-F-24385F.

The present disclosure relates to systems and methods for collecting batteries and other devices for disposal or recycling and suppressing fires during storage and/or transportation. In particular, in one or more embodiments, the disclosed systems provide a battery collection and fire suppression system comprising a battery collection bin with side vents in one or more sides of the battery collection bin. Also, in some embodiments, disclosed systems may include modular inserts configured to be inserted into the battery collection bin. Further, in some implementations, the disclosed systems may include fire suppressant configured to be inserted into the battery collection bin about the modular inserts that automatically is deployed during a thermal event.

The present disclosure provides a method for firefighting by use of a firefighting foam. The present disclosure also provides a firefighting system comprising a water supply line, a foaming concentrate dispenser unit and a polymer dispenser unit.

A fire extinguishing liquid is described comprising (a) one or more of a phosphate, hydrogen phosphate, dihydrogen phosphate or polyphosphate salt; (b) a carbonate or hydrogen carbonate salt; (c) a sulphate salt; and (d) an intumescent component. Methods of manufacturing the fire extinguishing liquid and fire extinguishers containing the liquid are also described. The liquid is useful for extinguishing fires, in particular lithium-ion battery fires.

A fire suppression composition includes starch, a pseudo-plastic, high yield, suspending agent, and agglomerating material.

A novel flame retardant and fire extinguishing product for preventing and fighting fires in liquids is disclosed herein. The product comprises water, one or more flame retardants, one or more polymers, one or more surfactants, one or more emulsifiers, one or more preservatives, and one or more firming agents. In some embodiments, the product may further comprise one or more stabilizers, one or more binders, and/or one or more fining agents. The product may be used as a fire extinguishing agent in active firefighting and as a flame retardant to prevent fires. The product may be biodegradable in a natural environment, may be readily cleaned off equipment and materials to which it has been applied using water, and may also provide other features which render it safe for the environment as compared to other commonly used products in fire prevention and firefighting.

The present specification discloses nontoxic fire extinguishing agent compositions, devices, methods and uses of same that are safe for both users and the environment. In particular examples, the nontoxic fire extinguishing agent comprises a microbial supernatant.

The compound below may be used in a fire-fighting formulation along with a poly(glucoside)-alkane, a poly(ethylene glycol) monoalkyl ether, and water. The value n is 2 or 3, R is a C3-C9 alkylene group, X is O or N(COCH.sub.3), and c is a positive integer. It may be made by reacting a polysaccharide with acetic anhydride, propargyl alcohol, and an azidoalkyltris(trimethylsiloxy)silane or an azidoalkylbis(trimethylsiloxy)methylsilane. Alternatively, it may be made by reacting a polysaccharide with propargylamine, acetic anhydride, and an azidoalkyltris(trimethylsiloxy)silane or an azidoalkylbis(trimethylsiloxy)methylsilane.
