The invention comprises a fire extinguisher and method, wherein the fire extinguisher has a sealable high-pressure container that forms a hollow interior connected by a valve to an environment external to the said container. The said container holds at a high pressure at room temperature a composition of liquid carbon dioxide and a non-hydrate, hydrophobic, cyclic organo-siloxane compound, the said compound further having a freezing point of at least −20° C. at one atmosphere. Upon release of the combination to the environment external to the container, the compound further produces a clathrate. In at least one embodiment of the invention, both the clathrate and the non-hydrate, hydrophobic, cyclic organo-siloxane compound have firefighting conductive properties.

A system including a plurality of display panels, each display panel being configured to display a portion of a simulated fire such that together the plurality of display panels display a composite fire image. Each display panel has a display portion configured to display the portion of the simulated fire and at least one sensor configured to detect an extinguishant directed at the display portion. Each display panel also includes a display panel controller operatively coupled to the display portion, the at least one sensor, and the display panel controller of at least one other display panel. The display panel controller is configured to at least partially determine qualities of a modeled fire; and determine changes of the modeled fire based upon inputs received from the at least one sensor. The display panel controller is also configured to cause the display portion to display the portion of the simulated fire based upon data or properties of the modeled fire. The display panel controller is configured to provide data relating to the modeled fire, at or adjacent to an outer edge of the display portion, to at least one adjacent display panel, and the display panel controller is configured to receive data relating to a modeled fire, at or adjacent to an outer edge of the at least one adjacent display panel.

A firefighting training system for use in training firefighters in the extinguishment of a simulated fire. The system includes a burn area disposed in a pit structure. The burn area includes a multitude of individual burn zones such that each of the individual burn zones can support a fire there within. The system further includes a control system to control the fire in each individual burn zone and a multitude of thermal imaging devices positioned to monitor the multitude of individual burn zones and to report the temperature of each individual burn zone to the control system.

A fire-fighting virtual reality simulator allows the trainee to move in a virtual space in various complex virtual fire disaster situations and perform a suppression of a virtual fire and a confrontation training. An experience interactive simulator for providing a trainee with a floor movement that may occur in a fire disaster situation so that the trainee wearing HMD in a virtual fire-fighting training has the same sense of feeling as that in an actual fire-fighting training is provided. For the realistic content experience, a physical floor movement, such as tilting, falling, and shaking of the floor is reproduced using a base motion, thereby providing a floor movement that enables a sense of feeling similar to a fire disaster situation.

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.

In one structural arrangement the fire fighting nozzle (18) is connected to the compressor (7) of a gas-turbine engine (4). In the second structural arrangement the fire nozzle (18) is connected to a screw compressor (50) connected to a diesel engine (47). Both types of fire extinguishing equipment have the same fire nozzle (18), whose mixing chamber (19) for the generation of a high-speed two-phase dispersive stream (21) of a bubble structure is made in the form of a block of mixers (35) with front and rear partitions (36,37), in between which pipe mixers (38) are located. Each mixer (38) is equipped with a confusor (43) and a diffusor (44). On the outlet from the fire nozzle (18) the high-speed dispersive stream (21) contains droplets of sizes 100-300 μm. The fire nozzle (18) has a mixing chamber (19), divided by partitions (36, 37) to a water supply chamber (40), air supply chamber (41) and dispersing chamber (39). The dispersing chamber (39) narrows into a gas-dynamic propelling nozzle (20), from which a high-speed dispersive stream (21) comes out. The fire nozzle (18) is connected to a rotating mechanism (22) which rotates it vertically and horizontally. The control unit (2) is equipped with a remote control (34) and connected to an generator (3).

A tile system for a burn room includes a plurality of interlocking surface tiles, each surface tile having an upper portion and a lower portion. The lower portion extends beyond at least a portion of a perimeter of the upper portion to define a flange. The system further includes a plurality of interlocking corner tiles configured to interact with at least one of the plurality of surface tiles; and a bracket system for securing the plurality of surface tiles and the plurality of corner tiles to a surface.

The present disclosure relates to methods and apparatus for launch and recovery of a remote inspection device within a liquid storage tank. In one embodiment, the tank is accessed by opening an entrance hatch and then injecting a vapor suppression foam across a surface of a stored liquid mass to form a foam layer. A launching system having a remote inspection device is attached to the entrance hatch to define a launch and recovery space sealed from an external environment and isolated from the stored liquid mass in the tank via a valve and the foam layer. The launch and recovery space is purged of hazardous vapors by injection of an inert gas prior to launch and recovery of the remote inspection device. Prior to removal of the launching system, the surface of the stored liquid mass is re-coated with vapor suppression foam.

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.
