An improved system and method for detection and suppression of fire that addresses the elements of the fire tetrahedron (e.g., heat, oxygen, fuel-rich smoke) to detect and suppress fires is described. Embodiments are comprised of a processor in communication with a detector, a fan, and a number of dampers. Upon detection of a triggering condition by the detector, the processor causes signals to be transmitted to the fan and dampers. Resulting changes to dampers and fans redirects airflow to evacuate heat, oxygen, and fuel-rich smoke through one or more vents in the compartment in which the triggering condition was detected. Advantages of described embodiments include utilizing existing HVAC systems, removing elements of the fire tetrahedron to suppress fires, and reducing unnecessary damage that may be caused by prior art suppression systems (e.g., sprinklers).

Apparatus and method for disposing of hot coals, e.g. charcoal briquettes after barbecuing or coals from a campfire. Sand and rain water are provided in a double-chamber device to cool it below ignition temperature. By strategically deploying the apparatus in campgrounds and forest preserves, park rangers may provide campers and hikers with a more effective tool for ensuring the fire is fully extinguished. Sand and rain water are provided in a double-chamber device to cool it below ignition temperature.

Described herein are zonal fire suppression systems and methods of using such systems for suppressing fires in cargo aircraft. A system is configured to individually monitor the temperature in each of multiple cargo zones in the cargo area. The system is also configured to selectively activate one or more of multiple zone distribution components to distribute a fire suppressant material, based at least on the temperature monitoring. The zonal approach to the temperature monitoring and to the fire suppressant material distribution allows reducing the fire suppressant material amount needed on the cargo aircraft, which, in turn, reduces the aircraft load. Furthermore, in some examples, the zonal approach eliminates unnecessary contact between the cargo (e.g., in the zones unaffected by fire) and the fire suppressant material. In some examples, this fire suppression involves depressurizing of the cargo area, in addition to or instead of the fire suppressant material distribution material.

The invention relates to an inertization apparatus for inerting a working volume in a chemical production plant by flushing with inert gas, where the chemical production plant comprises a plant-wide inert gas distribution system having pipes for distributing the inert gas and at least one inert gas offtake position which can be connected to a connecting conduit. According to the invention, it is provided that the connecting conduit between inertization apparatus and working volume is connected, at its end nearest the working volume, in a not reversibly detachable manner to an intermediate piece, where the intermediate piece can be connected in a reversibly detachable manner to a counterpiece provided on the working volume.

An electronic detection extinguisher system detects and extinguishes a fire which starts at the interaction of a fuel nozzle and the fuel inlet. The electronic detection extinguisher system is comprised of at least one controller which detects and sends signals, at least one sensor which sends signals to the encoder, at least one encoder which extends the signals provided by the controller or the sensor, at least one valve which is electronically controlled that releases the extinguisher solution or gas, at least one relay which provides direct current from the power supply to the electronically controlled valve, at least one relay which cuts the direct current of the fuel pump which stops the fuel from pumping, at least one extinguisher line which provides the gas or extinguisher solution to the tip of the extinguisher, at least one data cable which connects the encoder to the sensor, at least one source of extinguishing solution or gas, at least one regulator to regulate the pressure of the gas or extinguisher solution.

An oxygen-reducing installation and method include a compressed gas storage having a container for storing a compressed gas, which can be an oxygen-reduced gas mixture or an inert gas, and having a fluid connection to an enclosed area via a line system to feed at least a portion of the compressed gas to the enclosed area. A gas separation system provides an oxygen-reduced gas mixture and includes an outlet for delivery of the oxygen-reduced gas mixture produced in the gas separation system to the compressed gas storage and/or to the enclosed area as required.

A fire extinguishing system for a battery of a vehicle includes: a gas discharge part installed in a battery pack to discharge a gas inside the battery pack; a gas passage part through which a gas flow, the gas generated inside the battery pack when a fire occurs and discharged through the gas discharge part; a controller, which outputs a control signal for fire extinguishment when a fire occurs inside the battery pack; a vacuum pump installed in a gas passage part to operate according to the control signal outputted from the controller and to perform smothering extinguishment of fire inside the battery pack by sucking gas and air from inside the battery pack during operation; and a closed space part provided in the vehicle so that the gas and air sucked by the vacuum pump can be moved and stored thereto through the gas passage part.
