A fire suppression apparatus for a vehicle includes a sensor for detecting a condition of an object mounted in the vehicle, a controller configured to determine whether the condition of the object mounted in the vehicle, which is detected by the sensor, satisfies a predetermined criterion for determining outbreak of fire and to output a control signal for suppression of the fire when the condition of the object satisfies the predetermined criterion, and a spread bag apparatus mounted in the vehicle, which is configured to unfold a collapsed spread bag toward the object in response to the control signal from the controller such that the unfolded spread bag hermetically covers the object, thereby suppressing fire at the object.

The present invention discloses a fire extinguishing sheet which is used in places, facilities, devices, tools, structures and the like where a fire may break out, and which makes initial fire extinguishing possible. This fire extinguishing sheet contains at least a potassium compound as a fire extinguishing chemical that is thermally decomposed upon reaching a predetermined temperature and generates a fire extinguishing component; and this fire extinguishing sheet is arranged in places, facilities, devices, tools, structures and the like where a fire may break out. If a fire breaks out, aerosols containing potassium radicals (a potassium compound) are generated from the fire extinguishing sheet, and the chain of combustion is interrupted by a negative catalytic effect, thereby quickly extinguishing or suppressing the fire.

An apparatus for inerting a space includes a metal-air battery, a feed channel for the introduction of air from an air source to the metal-air battery, and a discharge channel for the discharge of air from the metal-air battery to a volume of the space. A control unit controls an electrochemical reaction of the metal-air battery as a function of a fire situation within the space. A method for inerting a space, an inerting system, an inerting method and an aircraft or spacecraft are also provided.

A system and method for inerting a protected space is disclosed. Process water is delivered to an anode of an electrochemical cell comprising the anode and a cathode separated by a separator comprising a proton transfer medium. A portion of the process water is electrolyzed at the anode to form protons and oxygen, and the protons are transferred across the separator to the cathode. Process water is directed through a process water fluid flow path including a gas outlet and a gas discharge valve in operative fluid communication with the gas outlet. Air is delivered to the cathode and oxygen is reduced at the cathode to generate oxygen-depleted air, and the oxygen-depleted air is directed from the cathode of the electrochemical cell along an inerting gas flow path to the protected space.

A system for preventing and/or extinguishing a fire in an enclosed target area in a vehicle. The system having a central compressed air source for supplying compressed air to a load circuit. A supply of compressed air is provided in a compressed air buffer tank is supplied to a gas separation device from the compressed air buffer tank. A nitrogen-enriched gas mixture is provided at an outlet of the gas separation device, and introduced into the target area. An inlet of the compressed air buffer tank is at least temporarily fluidically connected to an outlet of a central compressed air source, wherein compressed air can be supplied to the compressed air buffer tank. A fluidic connection is provided between the central compressed air source and the compressed air buffer tank if a load circuit is not drawing any compressed air from the central compressed air source.

The invention relates to a method for inertizing an oxygen-containing first gas present in a protective housing (4) surrounding a fuel cell (1), wherein a prescribed amount of a hydrogen-containing second gas is introduced into the protective housing (4) and at least part of the oxygen present in the first gas is reduced by cold combustion.

A fire suppression system includes a Coolant Infusion Spray Nozzle (CISN) and a Coolant Introduction Adapter Cap (CIAC). The CISN includes a water inlet and a coolant inlet. The CISN also includes a coolant infuser with infusion aperture(s) for injecting coolant into the water as it is bypassing the coolant infuser. This CISN generates a fire suppressing stream of coolant and water mixture. The CIAC supplies water and coolant to the CISN. The CIAC is coupled to a water source, and is also coupled to the CISN via hoses. The CIAC can includes an elbow for directing coolant toward the CISN.

A fire suppression system according to an embodiment of the present invention comprises: a detection unit for detecting a particular change due to a fire and transmitting a particular change value as a measurement value; a fire extinguishing unit for spraying a fire extinguishing substance; a control unit for receiving the measurement signal and transmitting an execution signal to the fire extinguishing unit; and a management unit enabling a user or a manager to confirm whether or not there is a fire, and for remotely, operating the fire extinguishing unit, wherein the control unit transmits a notification signal to the management unit only when a measured measurement data value exceeds a threshold value, and transmits the execution signal only when an operation command is received from the management unit, thereby enhancing convenience and safety and reducing the initial cost.

A system and method for providing dried inert gas to a protected space is disclosed.

An onboard inert gas system has an electrochemical and a membrane gas separator. The electrochemical separator includes an electrochemical cell including a cathode and anode separated by an electrolyte separator. An electrical power source provides power to the electrical circuit at a voltage that electrolyzes water at the anode and forms water at the cathode, or reduces oxygen at the cathode and forms oxygen at the anode. Oxygen is consumed at the cathode, providing nitrogen-enriched air. Nitrogen-enriched air from the cathode is connected by a flow path to the membrane gas separator, which comprises a membrane having a greater permeability to oxygen or water than to nitrogen. Nitrogen-enriched air from the membrane gas separator that is further enriched in nitrogen, reduced in water content, or both, is connected by a flow path to a fuel tank, a fire suppression system, or both a fuel tank and a fire suppression system.
