A control mechanism of a vehicle-mounted system for electromagnetic launch of fire extinguishing bombs for high-rise buildings is provided. A stress wave amplifier is fixedly connected to a secondary coil, a primary coil is fixedly connected to a coil base, a guide shaft passes through a central hole in the primary coil and the coil base, and a head of the guide shaft is fixedly connected to the secondary coil. A step-up transformer TM1 boosts a 380-V alternating current and changes it to direct current to charge a pulse capacitor C1 and store energy in the pulse capacitor C1. A discharge thyristor M3 is triggered, and the pulse capacitor C1 releases the energy instantaneously. A stress wave is generated between the primary coil and the secondary coil. The stress wave is transmitted to a fire extinguishing bomb through the stress wave amplifier, to launch the fire extinguishing bomb.

A fire extinguishing device comprising liquid nitrogen filled canister-tank attached to a device to release the LN contents; wherein, the release mechanism comprises a small explosive to tear open the canister and rapidly disperse the LN. The bombs are opened at desired locations and are delivered by any means comprising the aerial, vehicle, drone, robotic systems and hand operated by firemen. The device is used for the purpose of extinguishing forest fires or structure fires.

The fire-escape composition is composed of two components, one consisting essentially of urea, diammonium hydrogen phosphate, ammonium hydrogen carbonate, sodium bicarbonate, fluorocarbon surfactant and water; the other consisting of tartaric acid, potassium citrate and potassium dihydrogen phosphate, wherein the two components are combined before usage. The fire-escaping system comprises the fire-escape composition and a container with a chamber, wherein the container is to be applied to a fire so as to deliver the composition.

[Problem] To provide a fire-extinguishing liquid agent in which a fire-extinguishing agent is contained in a desirable balance and is satisfactorily dissolved in a solvent, that is easy to use, and that can be used against normal fires and oil fires, as well as fire-extinguishing equipment loaded with said fire-extinguishing liquid agent. [Solution] A fire-extinguishing liquid agent is sealed in an impact breakable container B that is molded by using a polystyrene resin material in which a general-purpose polystyrene and a styrene-butadiene copolymer are mixed and that has a hand-throwable size, wherein the fire-extinguishing liquid agent is formed: by containing 68-76 parts of sodium bicarbonate (NaHCO.sub.3) relative to 100 parts by weight of ammonium chloride (NH.sub.4Cl); by being treated by passing through a magnetic field having a magnetic flux density of 3000-10000 G; by being dissolved in hot water (magnetic water) in which the temperature thereof is adjusted to 30-50 C.; and by being adjusted to have a pH in a range of 7.5-10.

An aqueous fire extinguishing agent and a preparation method thereof are provided, which are used for making a throw-type fire extinguisher. The aqueous fire extinguishing agent is composed of two compositions of A and B. The composition A is a fortified water added with a flame retardant (e.g., one or more of ammonium chloride, diammonium hydrogen phosphate and ammonium polyphosphate), a wetting agent (e.g., alkyl polyglycoside) and a colloid (e.g., polyacrylamide solution). The composition B is a regulator. After the composition A and the composition B are mixed, a discharge rate/speed of fire extinguishing substances is increased, so that an escape passage/route can be opened up quickly.
