A fire extinguishing chimney bomb is disclosed herein. The device may include a flexible plastic receptacle and a fire extinguishing payload contained therein. The device is dropped down from the top of the chimney into the base of the fire. As the device enters the fire, heat from the fire melts the plastic, thereby releasing the extinguisher agent, which smothers the fuel and extinguishes the fire.

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 pilot and burner apparatus is provided for use in firefighting training. The apparatus includes a main fuel conduit and a main fuel valve. The apparatus includes a pilot tube and a pilot fuel conduit configured to deliver fuel from the main fuel conduit to the pilot tube. The apparatus includes main and pilot fuel valves to respectively control a flow of fuel in the main and pilot fuel conduits. In a pilot phase, the valves direct fuel to the pilot tube. An ignition component is configured to ignite fuel in the pilot tube to generate a pilot flame. In a burn phase, the pilot flame generates a controllable flame out of a main burner pipe by igniting fuel exiting the main fuel conduit. The controllable flame can be delivered to a training structure for training purposes.

A wind pressure type of haptic firefighting nozzle interface that is interworked with virtual reality (VR) content for virtual firefighting training is provided. The wind pressure type of haptic firefighting nozzle interface includes: a flow controller for adjusting a spraying intensity of water sprayed on the VR content; a stream shaper for adjusting a spray shape according to a radiation angle of the water sprayed on the VR content; and at least one first haptic device for providing haptic feedback corresponding to the spraying intensity and the spraying shape determined according to control through the flow controller and the stream shaper using wind pressure.

A fire suppression system includes a transport refrigeration unit configured to cool a transport container. Also included is a tubular container having a fire suppressant stored therein, the tubular container disposed within the transport refrigeration unit. Further included is a predetermined fracture location of the tubular container, wherein the predetermined fracture location is configured to rupture upon reaching a critical temperature to expel the fire suppressant.

The invention relates to a component of a gaseous fire suppression system. A concealed extendable nozzle for gaseous fire suppression systems is mounted on a distribution pipe of a gaseous fire suppression system. The nozzle consists of a body with discharge openings and a cap. A rod of a nipple is mounted inside the body of the nozzle. The nipple rod has a variable outside diameter: at one end, the rod narrows and ends in a connecting thread, whereas at the other end, the rod widens. Meanwhile, the body has an opening of variable diameter, which permits movement of the nipple rod inside the body; the body of the nozzle has a widening on the outside. A cap is fastened to the body of the nozzle, and this connection is tightly sealed by a washer. The technical result is the even dispersal of a gaseous fire extinguishant inside a room.

A fire extinguisher apparatus that consists on a loading lever network that gets built in the transport equipment allowing manipulation of the device that is directly introduced to the fire to compress it and by this, stopping the combustion process. Simultaneously, the said extinguishing apparatus will inject a series of substances over the flames, drastically reducing temperature of the fire zone, avoiding reignition when the device collapses on the different interventions these have.

The Main Lever of such network is originally built in to the transport equipment and one end will branch different tips which will form a net of smaller lever which will hang the TFI device. A tension cable will go across the upper part of the Main lever to bring more resistance and provide much more strength by preventing arcing of the lever when handling very heavy loads. A pipeline network that extends and is supported over and through the lever network, transports the cooling substances from the fluid deposits until the injecting sprinklers are arranged in the upper part of the attack devices.

An onboard electrochemical system of an electrochemical cell including a cathode and an anode separated by an electrolyte separator is selectively operated in either of two modes. In a first mode of operation, water or air is directed to the anode, electric power is provided to the anode and cathode to provide a voltage difference between the anode and the cathode, and nitrogen-enriched air is directed from the cathode to an aircraft fuel tank or aircraft fire suppression system. In a second mode of operation, fuel is directed to the anode, electric power is directed from the anode and cathode to one or more aircraft electric power-consuming systems or components, and nitrogen-enriched air is directed from the cathode to a fuel tank or fire suppression system.

Some embodiments and methods described herein relate to fire training systems and to fire simulators or fire training apparatus. In some embodiments, an apparatus includes a housing with a surface and an interior volume. A smoke generator is disposed within the interior volume of the housing and is configured to selectively generate smoke. A port is extended between the smoke generator and the surface of the housing and is configured to permit at least a portion of the smoke to be discharged through the port from the smoke generator to an exterior of the housing. A light emitter is coupled to the housing and configured to emit a light. The light and the portion of smoke are collectively configured to simulate a flame or electric arc above the surface of the housing such that the simulated flame or electric arc is viewable from more than 180 degrees about the surface of the housing. A logic controller is disposed within the interior volume of the housing and is configured to modulate the light and the smoke based on receipt of an extinguishing agent by a predetermined portion of the housing.

A system including an imaging device having a first image capture device configured to detect longwave infrared electromagnetic radiation and a second image capture device configured to detect near infrared electromagnetic radiation. The system further includes a display configured to display a visible representation of the detected infrared longwave electromagnetic radiation and the detected near infrared electromagnetic radiation.
