methods, apparatuses, and systems for harvesting inert gas exhausted from an engine and using the harvested inert gas to prevent an ignition event and/or extinguish an ignition event. The temperature of the harvested inert gas may need to be lowered. Unwanted components may be removed from the harvested inert gas. Combustion components may be completely burned from the harvested inert gas prior to providing the harvested inert gas to a fire protection system. The fire protection system uses the harvested inert gas to extinguish an ignition event and/or to provide a purge flow to prevent an ignition event. The fire protection system may be on an aircraft. Sensors may be used to detect an ignition event. Pressure sensors may be used to monitor the pressure of the harvested inert gas as well as to monitor the purge pressure of areas receiving a continuous purge flow of harvested inert gas.

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.

The present invention provides a fire extinguisher capable of easily installing a thinly molded fire extinguishing agent. A fire extinguisher of the present invention comprises a fire extinguishing agent layer that generates aerosol by combustion, a first plate covering a first surface of the fire extinguishing agent layer and having a blowout aperture for the aerosol, and a second plate covering a second surface of the fire extinguishing agent layer, which is opposite to the first surface. An edge of the first plate and an edge of the second plate may be connected to each other. And, a peripheral wall extending toward the second plate may be provided at the edge of the first plate.

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.

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.

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.

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.

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.
