The composition may be in the form of a dry concentrate, a liquid concentrate, or a final diluted product. The final diluted product is effective in suppressing, retarding, and controlling forest fires while exhibiting corrosion resistance and low toxicity.

A preparation method for a composite fire extinguishing agent with a cooling function is provided, comprising the steps of conducting refining and hydrophobic treating on heat-absorbing material; and mixing the treated heat-absorbing material and a fire extinguishing agent proportionally to obtain a composite fire extinguishing agent with a cooling function. The present invention enhances the cooling performance of the fire extinguishing agent by adding the heat-absorbing material on the basis of the existing fire extinguishing agent, wherein the heat-absorbing material can absorb the heat released by batteries through phase transition (solid-liquid) heat absorption and decomposition heat absorption.

Disclosed is a fire suppressant material for controlling or extinguishing a combustion process, the fire suppressant material comprising zeolite particles with an internal porous structure, wherein molecules of a fire extinguishing substance are contained within the internal porous structure of the zeolite material.

A system includes an energy storage system (ESS), having battery pods and one or more battery cells disposed within the battery pods. The system also includes an ESS trailer, the ESS mounted on the ESS trailer. Also, the system includes a water spray subsystem. The water spray subsystem includes a plurality of sprinkler nozzles mounted within the battery pods and a first fluid connection fluidly connecting the sprinkler nozzles to a pump package. In addition, the water spray subsystem includes a second fluid connection, fluidly connecting the pump package to a water storage supply. The system includes a dry chemical spray subsystem, which has a dry chemical supply vessel, the dry chemical supply vessel mounted to the ESS trailer and a plurality of dry chemical distribution nozzles mounted within the battery pods, the dry chemical distribution nozzles fluidly connected to the dry chemical supply vessel by dry chemical distribution piping.

An apparatus for applying carbon dioxide (CO.sub.2) in solid form to a target comprises an aggregated body production chamber for producing individual solid bodies of CO.sub.2 with defined shape using an endless type conveying member which carries a plurality of receptacles for receiving CO.sub.2 snow and allowing the same to harden therein to form the individual bodies during movement of the receptacles along the upper run before being discharged upon transition to the lower run. The apparatus includes a snow production chamber for producing CO.sub.2 snow, which is in communication with a discharge of the aggregated body production chamber and which comprises its own downstream outlet such that the CO.sub.2 snow acts to convey the individual bodies released from the discharge of the aggregated body production chamber and towards the target.

Dry powder chemical compositions for extinguishing fires involving flammable hydrocarbon liquids such as, oils, fuels and non-polar solvents such as ketones and alcohols. The dry powder chemical compositions are made by mixing, blending and milling to suitable powder particle sizes, the following components: a fire extinguishing agent in the form of at least one alkali metal salt of a nonpolymeric saturated carboxylic acid; a powder fluidizing agent to help provide the dry powder composition with excellent fluid flow characteristics; and a surfactant that promotes the formation of anhydrous semi-crystalline metal mineral salt film onto the surface of flammable hydrocarbon liquids, involved in the fire outbreaks to be extinguished and preferably absorbed by the dry powder chemical compositions.

A solid composition, which may be in the form of pellets, comprising at least two biopolymeric thickening agents, such as polysaccharides, wherein said solid composition is capable of forming hydrogels in the presence of water or an aqueous solution. The hydrogel is a water-enhancing, fire-suppressant that is useful for one or more of fire-fighting, fire-suppression, or fire-prevention and exhibits non-Newtonian fluidic, pseudoplastic or thixotropic behaviour.

The disclosure relates to firefighting measures, and in particular, to firefighting compositions for preventing, retarding and extinguishing fire in a combustion zone that comprises a combination of at least one cooling component, at least one fire-isolation component comprising, at least one oxidizer diluting component, and at least one flame retarding component.
