The present invention discloses a cooling type dry powder fire extinguishing agent and a preparation method and application thereof, which belongs to the technical field of fire control. Through a static mixing technology, an aqueous solution and a solid hydrophobic material are dispersed and mixed efficiently to form a cooling type dry powder fire extinguishing agent. The fire extinguishing agent is a micron solid particle of the aqueous solution wrapped by the hydrophobic material microscopically, and is in a dry powder state macroscopically, which can significantly reduce the electrical conductivity of the fire extinguishing agent. Meanwhile, a field rapid preparation method is adopted, which can realize real-time preparation. The preparation method is simple and efficient. The technology can be used for fighting a battery fire, has significant cooling and anti-reignition effects and can avoid the problem of electrical conduction of a traditional water-based fire extinguishing agent.

Electrical equipment including at least one electrical device and a housing that houses the at least one electrical device, wherein a fire extinguisher is provided to at least part of an inner wall of the housing to face the at least one electrical device; and the fire extinguisher includes a fire extinguishing material obtained by molding a composition that contains a fire extinguishing agent and a binder.

A system includes a pressure vessel defining an interior space with a discharge outlet. A valve or burst disc is connected in fluid communication with the discharge outlet. Discharge piping is included in fluid communication with the valve or burst disc to receive discharge from the interior space. One or more discharge nozzles are in fluid commination with discharge piping for issuing a spray from the discharge piping into the environment external of the pressure vessel. A mixture of liquid Carbon Dioxide (CO.sub.2) and a dry chemical fire extinguishing agent is housed under pressure within the interior space.

Provided are a battery pack and a control method using the same, the battery pack having improved safety so as to prevent fire or prevent fire from spreading even if ignited, thereby reducing the risks which can occur during ignition. The battery pack, according to the present invention, comprises: an electrode assembly comprising an anode, a cathode, and a separator; and a single cell or a plurality of cells having a pouch-shaped battery case for accommodating the electrode assembly, wherein the cell is accommodated and stacked by the module case, the module case comprises a fire suppression agent or a fire extinguishing agent at the inner or outer part thereof such that the fire suppression agent or the fire extinguishing agent is automatically discharged from the module case when cell swelling occurs.

A method of extinguishing or retarding fire can include disposing nano-clay onto the fire to retard or extinguish the fire. The nano-clay can be in the form of a powder. The powder can include nanoparticles having a particle size of about 1 nm to about 50 nm. The nano-clay can be used alone or mixed with water.

The invention relates to a material consisting of a preparation made from a mixture of ferrocene and an inert flameproof material such as plaster, the material being presented in the form of granules and being suitable for spreading over a hydrocarbon fire in a simple and rapid manner such that, under the effect of the heat from the fire, the ferrocene contained in the granulated material is diffused progressively and homogeneously in a vapor phase over the base of the flames, so as to optimize the combustion of the hydrocarbon and to reduce the emission of smoke and unwanted particles.

A fire retardant composition, gel, and a method of delivering a fire retardant, the fire retardant composition including: a polyacrylate polymer, a mixture of minerals of montmorillonite, quartz, and mica; and sodium oxide, and the method of delivering the fire retardant including providing the fire retardant powder composition; mixing water with the fire retardant powder composition in specific ratios; and delivering the fire retardant to a target zone.

A cellular phone case in combination with a flexible packet holding an admixture of water and super absorbent material to provide heat dissipation, heat indication, and fire extinguishment properties.
