A panel (10) for use as a fire suppressing system which comprises a substrate (12) and an exothermic gas producing charge (14) wherein the exothermic gas producing charge (14) is integral with the substrate.

A fire suppression system includes at least one spray nozzle for expelling a fire suppression agent into a space; a first container at least partially filled with a first fire suppression agent. The first fire suppression agent within the first container has a first pressure. A conduit extends from the first container to at least one spray nozzle. A second container is at least partially filled with a second fire suppression agent and is arranged in fluid communication with the conduit. The second fire suppression agent within the second container has a second pressure less than the first pressure. A mixture of the first fire suppression agent and the second fire suppression agent is movable through the conduit to the at least one spray nozzle via the first pressure.

A system for mixing fire-suppressant gel with water on board an aircraft includes a gel reservoir mounted in the aircraft, a pump for injecting gel into a flow of water into an aircraft-mounted payload tank, and a control system for controlling gel-water mix ratios. The control system monitors water volume flowing into the water tank, and regulates the gel pump to inject gel in appropriate amounts to produce gel-water emulsions having precise gel-water ratios. Settings for the control system are set by the pilot before water flow water is initiated. Once the aircraft is in flight, the gel-water mixing process is automatically controlled through a trigger on the pilot's control stick. The aircraft may be a helicopter or fixed-wing aircraft adapted to load water from a lake or other source while in flight, or a fixed-wing aircraft adapted to load water on land from a pressurized water source.

A system and method for providing inerting gas to a protected space. Oxygen is directed from an oxygen source to a motive port of an ejector, and air is introduced to a suction port of the ejector. A gas mixture of oxygen and air is directed from an outlet port of the ejector to a reactor, and a reactant is directed from a reactant source to the reactor. Oxygen in the gas mixture is reacted with the reactant to incorporate the oxygen into a non-combustible compound, and an inerting gas comprising the non-combustible compound is directed to the protected space.

A forest fire retardant composition is substantially free of ammonium and includes an organophosphate derived from (i) a phosphorylation agent and (ii) an organic molecule comprising at least two hydroxyl groups. The organophosphate may contain at least one phosphate ester bonded to an organic molecule, wherein the organic molecule comprises at least one monomer unit of about 2 to 40 carbon atoms. Preferably, at least 90% of the functional groups of the organophosphate is a phosphate ester group. The composition may also include a salt, including magnesium salt and/or calcium salt. The anion in the salt may be hydroxide, carbonate or phosphate. The salt may be an anhydrous salt, a salt hydrate, or a combination of both. The composition is effective in suppressing, retarding, and controlling forest fires while exhibiting corrosion resistance and low toxicity.

Fire-fighting device with at least one generator arranged for discharging fire-fighting agent, an electrically triggerable ignition means arranged in the generator, the ignition means being controllable via an at least two-pole control connection. A bypass circuit electrically arranged at the control connection detects a tiggering of the ignition means and closes a switch when the ignition means is released.

Fire fighting apparatus using a single pressurizing pump and an improved eductor venturi to enable the in-line eduction of a long term fire retardant concentrate into a pressurized diluting water flow stream downstream of the water pressurizing pump so that the resulting mixture of water and liquid concentrate is accurately proportioned to meet a specification dictated by the concentrate vendor and is thus instantly available for application to fire threatened structures and vegetation.

Invention relates to a fire suppressing gas generating device. The device comprises a housing with an array of discharge openings. The device further comprises a plurality of gas-generating grains disposed within the housing; a multi-layer filter; an ignition device associated with the gas generating grains for ignition of said the gas-generating grains; and a foil section disposed over said discharge openings.

Disclosed is a fire suppressant system for an aircraft having: a source of a fire suppressant; a tubing system for delivering the fire suppressant to one or more predetermined locations; and a discharge nozzle disposed in the one or more predetermined locations, the discharge nozzle connected to the tubing system for distributing the fire suppressant in the one or more predetermined locations during a fire, the discharge nozzle including a plurality of nozzle heads including a first nozzle head with a first flow area and a second nozzle head with a second flow area that differs from the first flow area.

An aerial jet engine fire extinguishing methodology includes: identifying an undesired fire; providing an airplane with at least one jet engine with an exhaust that may be directed toward the fire; flying the airplane in the proximity of the fire with the exhaust directed toward the fire, the flying being at an altitude sufficient to deliver carbon dioxide and other exhaust gases from the exhaust to the fire to at least partially deprive the fire of oxygen and to thereby snuff out at least a portion of the fire. The airplane may be manned or an unmanned drone.
