An example apparatus includes a cabinet body and a first storage receptacle at the cabinet body. The first storage receptacle is to temporarily store an electronic device. The apparatus further includes a second storage receptacle at the cabinet body. The second storage receptacle is to temporarily store another electronic device. The second storage receptacle is separate from the first storage receptacle to prevent physical access to the first storage receptacle through the second storage receptacle. The apparatus further includes a fire suppression mechanism to independently suppress a fire in the first storage receptacle or a fire in the second storage receptacle.

A system for fire suppression in an aircraft includes hot and cold coolant lines, a heat exchanger separately coupled to the hot coolant lines and to the cold coolant lines, and spray outlets along the coolant lines. Smoke or fire detectors are disposed at multiple locations of the aircraft. In certain examples, the coolant lines having supercritical carbon dioxide (SCO.sub.2) circulating therein. Regulating valves are coupled to the spray outlets to control flow of the SCO.sub.2 through the spray outlets. A controller manages activation of the regulating valves to spray SCO.sub.2 through the spray outlets.

A fuel break with integral watering system includes watering towers with associated pumps and water supplies that apply water to fuel break vegetation when needed, such as during a drought and/or when a fire is approaching. Water can be delivered by pipes from a remote water source, and/or collected as runoff water in reservoirs below the watering towers. Sensors can monitor water content of the reservoirs, and/or moisture content of surrounding soil, vegetation, and/or air. The towers can be remotely powered by wires, and/or by batteries recharged by solar panels. The watering system can be configured to apply water both to tall vegetation and to ground vegetation. Super-absorbent polymer added to the fuel break can absorb and retain rain water and water from the towers. Reforestation can include planting fire resistant trees in bunches, locating the towers near the bunches, and/or relocating power lines below grade.

A fire suppression system that includes a non-rigid pouch, a quantity of suppressant, a quantity of gas, and a pressurized gas source. The non-rigid pouch that includes an exterior surface and an interior space. The quantity of suppressant, the quantity of gas, and the pressurized gas source is contained within said interior space. The pressurize gas source is configured to increase the internal pressure of the non-rigid pouch by injecting gas into the interior space. The non-rigid pouch is configured to rupture when the internal pressure exceeds a predetermined threshold pressure.

In a method and apparatus for contacting battery cells of a battery module by welding, module of at least two battery cells is inserted into a battery module holder, whereupon electrical connectors of the at least two battery cells are welded together. The battery module holder is in a battery extinguishing container that is open toward the top for access by a welding device and is connected via at least one extinguishing agent line to a liquid extinguishing agent reservoir for transfer of the liquid extinguishing agent from the reservoir into the battery extinguishing container.
