A fire extinguishing equipment with improved characteristics which includes a pressure-resistant storage body with an internal space that houses a fire extinguishing composition. A monitoring unit is connected to the storage body to measure and regulate one or more physical characteristics. At least one discharge outlet is in communication with the internal space of the storage body and is configured to discharge the fire-extinguishing composition from the internal space to a use location. A charging inlet is disposed within the storage body and is configured to fill the internal space with the fire-extinguishing composition. An extinguishing-launching part-unit is inserted into a pipe section between the use location and the discharge outlet.

Disclosed is a firefighting composition of the surfactants below and water. The values of m, n, x, and y are independently selected positive integers. R is an organic group. R′ is a siloxane group.

An anti-sinking and anti-fire safety system for boats includes inflatable devices, is installed in a first deflated configuration and assumes a second irreversibly inflated configuration, with a volume considerably greater than the first deflated configuration. Each inflatable device is connected to at least one dispenser expanding a predetermined quantity of non-inflammable foam within the corresponding inflatable device to assume the desired volume in the second inflated configuration. Each dispenser is connected to an activator to activate the corresponding dispenser by remote control of the user, sent by a control system. The emergency system also includes dispensers, connected to the activator expanding non-inflammable foam between the free spaces present between the inflatable devices already inflated, and in any other fire risk space. The non-inflammable foam sublimates after a known time. The control system includes a processor and a communication interface.

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.

A method of manufacturing a self-expanding fire-fighting foam solution is disclosed. Here, the method can include purging air from a container, wherein the purging is performed via flowing an inert gas into the container, such that substantially inert environment is created within the container. In addition, the method can further include dispensing or filling a pre-determined amount of foam concentrate into a container, dispensing or filling a pre-determined amount of water into the container, and mixing the foam concentrate and water within the container, wherein the mixed foam and water within the inert container provide the self-expanding fire-fighting foam solution and having a pH ranging from about 6.8 to 7.8 moles per liter.

A pump combination guard and methods of use thereof, having an inner housing or guard configured to cover mechanical seal assembly and the motor coupling housed between a drive motor and a fluid pump to enable foam spray nozzles to be directly inserted into the coupling guard housings for fire suppression and an outer “Air scoop” housing or guard configured to direct motor induced airflow over the mechanical seal assembly thereby enabling fire protection and cooling to extend seal life and to protect mechanical seals from pre-mature failure.

A method of fighting a fire includes aerating a firefighting foam composition to form an aerated firefighting foam; administering the aerated firefighting foam to a fire or applying the aerated firefighting foam to a surface of a volatile flammable liquid; wherein: the firefighting foam composition includes a sugar component; a surfactant component comprising an anionic surfactant, a zwitterionic surfactant, or a mixture of any two or more thereof; a polysaccharide thickener comprising succinoglycan; and at least about 30 wt. % water.

A method of fighting a fire includes aerating a firefighting foam composition to form an areated firefighting foam; administering the aerated firefighting foam to a fire or applying the aerated firefighting foam to a surface of a volatile flammable liquid; wherein: the firefighting foam composition includes a sugar component that includes a monosaccharide sugar and/or a sugar alcohol; an anionic surfactant; a zwitterionic surfactant; an organic solvent including glycol ether and/or glycol solvent; a polysaccharide thickener; and at least about 40 wt. % water; wherein the composition is substantially free of any amine oxide or nonionic surfactants; and the composition is substantially free of fluorinated compounds.

An explosion suppression insert for a fuel tank includes a hollow body having an inner surface and an outer surface, the hollow body being made of an explosion suppressing material; and a plurality of perforations defined in the outer wall. In some embodiments, a nonwoven explosion resisting insert for a fuel tank includes a body including a plurality of interconnected non-woven fibrous struts being made of an explosion suppressing material, the body having a first end and a second end; and a plurality of voids defined by the plurality of struts, the voids being configured such that the body has a porosity of between 5 pores per inch and 50 pores per inch. Methods of manufacturing explosion resisting inserts are also provided.

A fire-fighting foam stock tank includes a stock solution tank, a bladder set inside the stock solution tank, and a liquid collecting pipe installed inside the bladder. The stock solution tank has a first end tank wall provided with a first maintenance hole and a first hole cover. There is a hole plug on the inner surface of the first hole cover, so that the hole plug extends into the first maintenance hole until it is close to the inner wall surface of the stock solution tank, so that the inner wall surface is kept flat. The liquid collecting pipe is a T-shaped pipe composed of a first pipe section and a second pipe section. The bladder fits the liquid collecting pipe shape.
