The description relates to battery safety and more specifically to containing battery fires. One example can include displacement sub-systems configured to physically separate an affected battery pack from other battery packs. Another example can include a 3D deployable fire curtain configured to automatically deploy around a battery pack to limit the spread of fire between battery packs. A further example can include a media reservoir positioned over a battery pack that is configured to hold non-combustible smothering media. A media retainer can be interposed between the battery pack and the media reservoir and configured to automatically release the non-combustible smothering media into the battery pack support structure when the battery pack experiences a fire.

A fire suppression system for an enclosed space, such as within a lavatory of a vehicle, includes a first inner gate, a second inner gate coupled to the first inner gate to define one or more air channels therethrough, and a temperature-responsive device coupled to one or both of the first inner gate or the second inner gate. The temperature-responsive device is configured to be in a first state below a predetermined temperature threshold, and a second state above the predetermined temperature threshold. In the second state, the second inner gate is moved relative to the first inner gate to close the one or more air channels.

A system and method for reducing the risk of fire in an oxygen delivery system. The system may include an oxygen delivery device with a controller in communication with a flow control valve to control a flow of oxygen through a tubing from an oxygen source to a patient interface. The controller may be programmed to close the flow control valve for a predetermined time period at a predetermined time interval to cause a periodic oxygen pause, the periodic oxygen pause to remove oxygen that may serve as an oxidizer when a fire is present inside at least one of the patient interface and the tubing.

A flame front in a gas pipeline is extinguished by introducing an extinguishing agent at an overpressure at an extinguishing zone of the pipeline. Using an overpressure provides a better and finer atomization of the extinguishing agent, and permits a greater amount of the extinguishing agent to be provided in the extinguishing zone per unit time. In addition, a sealing fluid is introduced at sealing zone of the pipeline. Gas flowing through the pipeline must flow through the sealing fluid in the sealing zone. Preferably, movement of a flame front from one side of the sealing zone to the other side of the sealing zone is prevented or reduced by the sealing fluid.
