Gravity-laid inorganic fiber webs and methods of making and using are disclosed. The gravity-laying process comprises mechanically separating inorganic fibers and collecting the fibers as a web, and may comprise blending of multiple types of inorganic fibers and/or blending of inorganic particulate additives with the fibers.

A control system for use with a fire-fighting device connected to a pump includes a user interface configured to receive a user-requested parameter of fluid, and a base component in communication with the user interface. The base component includes a programmable logic controller having predefined logic stored thereon. The base component automatically controls operation of the pump based on the predefined logic, the user-requested parameter of fluid, and at least two of: a first actuation state of a first valve configured to control a first flow of liquid from a storage tank at the fire-fighting device, a second actuation state of a second valve configured to control a second flow of liquid from a remote water source, a third actuation state of a third valve configured to control a third flow of liquid to a nozzle, a volume of water stored at the storage tank, and a water pressure associated with the remote water source.

A fire extinguisher includes one or more sound waves fire extinguishers. Additionally, the fire extinguisher includes processing circuitry configured to receive output from one or more sensors, determine if a fire related event is detected based on the output from the one or more sensors, and activate the one or more sound waves fire extinguishers in response to detection of the fire related event to minimize the fire related event via mechanical pressure waves.

Noise and room air overpressure on discharge of a gas extinguisher system is reduced. During the discharge, an extinguishing fluid is conveyed from a pressurized container via a container valve and line system to an extinguishing nozzle. At the beginning of the discharge the extinguishing fluid is predominantly present in the line system in liquid phase and after discharge it assumes a predominantly gaseous phase. In a phase transition period, which is accompanied by a significant reduction in the extinguishing fluid mass flow and a significant increase in the noise and the room air pressure, the mass flow is then reduced or stopped. Due to the reduction of the mass flow, the sound level of the noise arising is advantageously reduced to a value of a maximum of 100 dB and the room air pressure to an overpressure value ranging from 200 to 1000 Pa.

Embodiments of the present invention are directed towards fire blocking apparatuses. A fire blocking apparatus for a solar panel is mounted to an underlying mounting surface. The fire blocking apparatus includes a panel support structure sized and shaped to be mounted between a solar panel and the mounting surface thereby supporting and creating a gap between at least a portion of the solar panel and the mounting surface, where at least a portion of the panel support structure comprises a heat or fire sensitive material configured to melt, deform, or warp at a predetermined temperature such that when the structure is mounted between the solar panel and the mounting surface and heated at or above the predetermined temperature, the panel support structure collapses to reduce the gap between the at least a portion of the solar panel and the mounting surface.

A method for efficiently treating spontaneous ignition of the remaining coal in a large area goaf of a shallow-buried coal bed, which method integrates leaking stoppage, airflow control and fast inerting and cooling so as to efficiently prevent and treat the spontaneous ignition of the remaining coal in the large area goaf of the shallow-buried coal bed.

A method for fire prevention and/or fire fighting on board an aircraft comprises the steps detecting a fire event, leading an extinguishant to a fire source through a cooling-system piping system (12) which serves, in the normal operation of the aircraft, to supply a refrigerant to a cooling station (14a, 14b) and/or discharge a refrigerant from a cooling station (14a, 14b), and flooding the fire source with the extinguishant.

The present disclosure relates to a broadhead cutter activation mechanism and system inside of a fire extinguisher. The broadhead cutter device may be attached to a cutter shaft which is driven downward when the elastic potential energy is released form a spring system. The broadhead cutter device may be configured to pierce and open a burst disc to release the flow of an extinguishing agent under pressure.

An enhanced shipping container apparatus that maintains packages is described having integrated fire suppression. The apparatus has a container base supporting the packages, multiple container walls coupled to the container base, and a container top coupled to each of the container walls. A fire suppression panel is integrated as part of one or more of the walls and top portion, and has a support sheet of fire resistant material; an interior exposed sheet of temperature sensitive material; a sealed boundary connecting the support sheet and interior exposed sheet on peripheral edges (where the sealed boundary, support sheet and interior exposed sheet define a holding cavity), and integrated fire suppression material in the holding cavity. The temperature sensitive material of the interior exposed sheet releases the integrated fire suppressant material from within the holding cavity when the temperature sensitive material of the interior exposed sheet is exposed to a threshold temperature.
