Described are inerting systems that may be used on board an aircraft or other passenger transportation vehicle to reduce a risk of fire due to electronic components or to other elements in a compartment and to assist in preventing or extinguishing any fire or hazardous condition that may occur. The systems include a source of inert gas such as oxygen depleted air generated from a fuel cell on board the aircraft. The oxygen depleted air or other inert gas is conveyed through ducts to compartments that house the electronics, thus changing the conditions in the compartment to be less conducive to fire.

A gas-generating pyrotechnic composition has a high gas yield while having reduced generation of condensable species and a limited combustion temperature.

Invention relates to fire suppressing gas generating devices, especially to a gas outflow management in the fire suppressing gas generating devices. A fire suppressing gas generating device comprising a cylindrical housing (1) having at least one discharge opening (13); a plurality of gas generating grains (2); an ignitor (5) associated with the gas generating grain (2) for ignition of said gas generating grain (2); a filter (6) encompassing the plurality of the gas generating grains (2); and at least one gas discharge channel (7) connected to the discharge opening (13). The gas discharge channel (7) further comprises at least two nozzles (17) opposed to each other creating thrust neutrality of discharged gas.

Disclosed herein is a solid aerosol detonator capable of generating a fire extinguishing gas by vaporizing an internal solid fire extinguishing agent in order to extinguish a fire which may be generated in a place to live or an industrial place and a fire extinguishing apparatus using the same. The solid aerosol detonator and the fire extinguishing apparatus using the same can be detonated using only a fire extinguishing agent of a solid form without using an electronic match or an ignition agent, that is, a material coated on an electrical percussion. Accordingly, the combustion action of a solid aerosol can be stably generated because the solid aerosol detonator and the fire extinguishing apparatus using the same are not sensitive to a change in the physical properties and a change in the temperature even after a lapse of a specific time.

A combustible aerosol composition is disclosed including an oxidizer including potassium bromate, a fuel including potassium cyanurate, and a hydrated mineral composition including potassium hydromagnesite.

Fire protection and suppression apparatus, materials, systems, and methods of use thereof are disclosed. In fire extinguishing applications, aerosol extinguishing agent in sheets, panels or other forms can be placed in a variety of implementations, including one or more of, but not limited to, inside an enclosure that contains a fire hazard, in an interior of a fire hazard itself, incorporated into a structure of a fire hazard. Once initiated, the aerosol extinguishing material will burn to create and directly disperse the aerosol particulate that can extinguish the fire. Initiation of the aerosol agent can be by flames or heat from an unwanted fire. Alternative methods of initiation include electric initiators that are signaled by automatic fire detection systems, electric manual methods, or mechanical/thermal initiators.

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 triggering of the ignition means and closes a switch when the ignition means is released.

A device for suppressing and/or extinguishing a fire associated with a container may include a housing defining a hollow sleeve and a column configured to be received within the hollow sleeve. The column may define a first chamber, a second chamber, at least one aperture, and a piercing end configured to pierce a barrier. The first chamber may be configured to receive an expansion agent, and the second chamber may be configured to receive a fire extinguishing agent. The device may be configured such that upon activation of the expansion agent, the column extends from the housing so as to enable the piercing end to penetrate the container and to enable the fire extinguishing agent to be delivered into an interior of the container via the at least one aperture.

The present disclosure discloses a battery casing, a method for manufacturing the same, and a device including a battery casing. A battery casing includes a casing body, a plurality of battery cells accommodated in the casing body, and a fire protection plate which is disposed inside the casing body at least corresponding to the plurality of battery cells and includes a thermal aerosol fire protection layer which includes an aerosol generating agent, wherein a total mass A of the aerosol generating agent in the casing body and a free space volume B of the casing body satisfy a relationship as represented by 0.03 g/L≤A/B≤8 g/L.

Fire protection and suppression apparatus, materials, systems and methods of use thereof are disclosed. In fire extinguishing applications, a convergent-divergent nozzle is incorporated into a pyrotechnic aerosol generator to improve the discharge characteristics when combined with air induction, reduced quantity of cooling media, and re-shaped agent/combustion chamber for longer discharge duration. In fire extinguishing applications, aerosol extinguishing agent in sheets, panels or other forms can be placed inside an enclosure that may have a fire. Once initiated, the aerosol extinguishing material will burn to create and directly disperse the aerosol particulate that can extinguish the fire. Initiation of the aerosol agent can be by flames or heat from an unwanted fire. Alternative methods of initiation include electric initiators that are signaled by automatic fire detection systems, electric manual methods, or mechanical/thermal initiators.
