An environmentally-clean aqueous-based fire extinguishing biochemical liquid concentrate to be mixed with a proportioned quantity of water, to produce a fire extinguishing water stream that produces good immediate extinguishing effects when applied to extinguish a burning or smoldering fire, and good long-term fire inhibiting effects when being proactively applied to protect combustible surfaces against the threat of fire. The environmentally-clean aqueous-based fire extinguishing biochemical liquid concentrate includes: a dispersing agent realized in the form of a quantity of water, for dispersing potassium ions dissolved in water; a fire inhibiting agent in the form of at least one alkali metal salt of a nonpolymeric saturated carboxylic acid, specifically potassium citrate, for providing potassium ions dispersed in the quantity of water when the potassium citrate is dissolved in the quantity of water; and a dispersing agent in the form of triethyl citrate, an ester of citric acid, for dispersing the potassium ions in the quantity of water, and lowering the surface tension of the liquid solution formed when the potassium citrate is dissolved in the quantity of water, forming of a fire extinguishing liquid solution, for mixing with a proportioned amount of water, to produce a fire extinguishing water stream having good immediate extinguishing effects when applied to extinguish a burning or smoldering fire, and good long-term fire inhibiting effects when applied proactively to protect combustible surfaces against the threat of fire ignition and flame spread of an incident fire.

A method for the suppression of coal seam fires provides for the location and determination of the boundaries of a coal seam fire, directing access to the coal seam, preparation of the coal seam prior to suppression and the suppression of the fire within the coal seam using a foam mixture, the method providing minimal impact and disruption to the surface above the coal seam fire.

Described herein is a firestop system for marine or off-shore applications comprising a foam layer comprising at least one fire-stopping additive and a non-porous structural sealant layer.

The installed fire fighting apparatus has one or more forwarding pipelines to transfer a fire extinguishing substance composition to a place of use, and one or more spreading devices connected to the output end of the forwarding pipeline, serving for directed discharge of the fire extinguishing substance composition and designed to be fixed to a flammable object. The apparatus includes a storage pipeline to store the fire fighting substance composition, comprising a pipeline with a cross-section exceeding the cross-section of the forwarding pipeline and closed at its ends or closed into itself like a loop, where the storage pipeline is equipped with a feeder pipe end with a pressure-tight shut-off device, a valve on the feeder pipe end, as well as a device to measure pressure in the interior space of the storage pipeline and a safety fitting, preferably a safety valve. The storage pipeline has a forwarding branch-off, to which branch-off the forwarding pipeline is connected by its input end. The forwarding pipeline has a flow control valve inserted both beside the branch-off location and at a distance therefrom, and a pressure release branch-off is fitted between the two flow control valves, where such pressure release branch-off is equipped with a shut-off valve. There is a fire extinguishing substance composition filled in the storage pipeline, which is a mixture of a fire fighting substance and a pressurized gas. The apparatus is fitted with at least two individual fire sensors designed to be located at various places of the flammable object and capable to distinguish fires according to extinguishing output demand.

An Aerosol Fire Extinguisher with Trigger Sprayer that can be easily held in one hand that contains in one embodiment of the invention the fire extinguishing agent in a a bag under pressure in an aerosol can and can only be released by pulling the tab of the trigger assembly. In another embodiment of the invention the Aerosol Fire Extinguisher with Trigger Sprayer does not have a bag but utilizes traditional aerosol technology with unique gases. The trigger sprayer is open when the tab is pulled. The Aerosol Fire Extinguisher with trigger sprayer is cylindrical canister housing and a valve for directing the product flowing out of the can. Pulling the tab of the trigger assembly allows pivoting member of the trigger assembly to be able to press down on the stem of the mounting cup of the aerosol can which then allows the pressurized gas in the aerosol can to force the fire extinguishing liquid through the dip tube up through the direction hole into the direction chamber with pressure out the nozzle toward the fire. The user then sprays the fire with the extinguishing agent until the fire is out.

A suppression system for use in a safety railcar may include a source of pressurized water connected to at least one foam tank containing a suppression foam. A controllable valve mediates flow of pressurized water from the source of pressurized water to the at least one foam tank. The controllable valve is controllable to permit flow of pressurized water to the at least one foam tank in response to detection of a hazardous event. A spray nozzle is connected to the foam tank via a rupture disc that is configured to rupture and permit flow of suppression foam from the spray nozzle when pressure within the foam tank exceeds a predetermined threshold.

A fire suppression system for a fire zone including a first tank containing a first liquid component of a two-part foam and a second tank containing a second liquid component of the foam. The system includes at least one liquid component release device configured to be selectively capable of releasing the first and second components from their respective containers upon receipt of a signal from a fire detector upon detection of a fire. The two-part foam components are propelled through the system by a pressurized propellant that, upon release of the release device, causes the exit of the foam components from their respective tanks, through a mixing conduit to at least one nozzle. The nozzle is configured to spray the liquid component foam mixture into the fire zone wherein the foam cures into a substantially semi-rigid, closed cell foam that is substantially impermeable and may have charring and/or intumescence properties.
