A fire suppression system (20) has a gas source (22) and at least one vessel (60) containing a liquid suppressant (62). A respective flowpath extends from each said vessel to one or more associated first outlets (73). A respective propellant flowpath extends from the gas source to each said vessel and is coupled to a headspace (70) of the vessel. At least one first pressure reducing device (30) and at least one second pressure reducing device (44) are in series along the propellant flowpath between the gas source and the at least one vessel.

A system of reducing the spread of wildfires is provided. The system includes a fire retardant delivery system comprising one or more reservoirs containing a fluid under pressure and one or more distribution devices in fluidic communication with a single reservoir. One or more sensors for sensing characteristics of a fire may be configured in operable communication with the reservoirs and/or the distribution devices, such that upon direction from the sensors the fluid can be delivered to ambient surroundings. In addition, the system may include one or more conduits between the reservoir of fluid and the distribution devices, such that the conduits can elevate the distribution devices above surrounding buildings and vegetation to provide that the fluid is distributed about the reservoir without the surrounding building or vegetation interfering therewith.

An automated and remotely-controllable wildfire ember misting-type suppression system and method that employs an electronic wildfire ember detection device using infra-red (IR) and other thermal-imaging sensors, and relative humidity sensors, to automatically detect the presence of a wildfire in the vicinity of the wood-framed building and automatically generate a cloud of wildfire ember suppressing mist consisting of microscopic droplets of clean anti-fire (AF) liquid that (i) instantly evaporates into vapor when contacting a flying wildfire ember and (ii) breaks and/or interferes with free-radical chemical reactions supported on the surface of each combusting wildfire ember flying in the wildfire storm moving about the wood-framed building.

A fire suppression system is disclosed. The system comprises a housing having one or more ports to receive a nozzle of a fire extinguisher. The fire extinguisher itself includes a container to house a fire-extinguishing fluid, the container being fluidly linked with the nozzle. Actuation of the nozzle allows fire-extinguishing fluid to exit the container via the nozzle, whereby insertion of a nozzle into a port actuates the nozzle. The or each port is in fluid linkage with a distribution head by means of a pipe to distribute fire extinguishing fluid, the port and the distribution head being fluidly linked.

A safety assembly provided with an automatic fire extinguisher system includes an engagement member, a blocking member, and an extension member. The engagement member is slidably received within an outlet port of a valve housing. A blocking member having a first blocking member portion and a second blocking member portion is at least partially received within a cavity defined by the valve housing. The extension member extends between the engagement member and the blocking member.

A metering cargo fire inerting assembly is activated to supplement an initial release of fire extinguishing fluid into a cargo hold of an aircraft when a fire is detected during flight. The metering components of the fire inerting assembly control the temperature and pressure of the fire extinguishing fluid within a metering container. A heater element within the metering container controls temperature and pressure. A flow control metering orifice is immersed in a portion of the fire extinguishing fluid sealed by a hermetically sealed disc downstream of the metering orifice. A cutter with an internal fluid flow passageway can pierce the disc to release the fire extinguishing fluid under control of a timer attached to the metering container that can activate a pyrotechnic charge to drive the cutter for releasing the fire extinguishing fluid such as Halon 1301 to a discharge outlet for delivery to the cargo hold.
