The present invention provides a fire suppressant system for vehicles and method for preventing fire outbreak within a vehicle's fuel tank or expulsion thereof.

A multi-function tank tool including a body, an internal passageway, an upper end and a lower end. The lower end is configured to connect a hose so that a fluid travels in the internal passageway. The upper end includes at least one opening communicating with an interior of the tank. A first hose can be connected to a lower end of the body. The tank may have oil, vapor and an oil/vapor interface. The tank tool can perform at least one of the following: grounding an interior of the tank using at least the tank tool and the first hose; agitating one or more fluids traveling through the internal passageway to mix the one or more fluids traveling through the internal passageway; directing a hot oil adjacent the oil/vapor interface using at least the tank tool and the first hose; and, attaching the tool to a floating tank roof.

The invention relates to an inertization apparatus for inerting a working volume in a chemical production plant by flushing with inert gas, where the chemical production plant comprises a plant-wide inert gas distribution system having pipes for distributing the inert gas and at least one inert gas offtake position which can be connected to a connecting conduit. According to the invention, it is provided that the connecting conduit between inertization apparatus and working volume is connected, at its end nearest the working volume, in a not reversibly detachable manner to an intermediate piece, where the intermediate piece can be connected in a reversibly detachable manner to a counterpiece provided on the working volume.

A fuel tank inerting module, a fuel tank inerting system for an aircraft, and a method of providing fuel tank inerting systems for aircraft are disclosed. The module includes an inlet for ullage gas from a fuel tank, a catalyst, an outlet for the ODA, sensors, filters and valves. The module is sized and shaped to fit in a range of positions near to fuel tanks in various aircraft. The inerting system includes one or more modules connected to the fuel tanks and a controller to control passage of ullage and ODA between the fuel tanks and the modules. The method includes providing an inert gas generation module compatible with any suitable aircraft, positioning one or more modules in an aircraft at locations near to a fuel tank to be inerted.

Fixed systems and method for extinguishing large scale industrial tank fires, with and without fixed roofs, and featuring aerated foam projecting nozzles and including fixed center directed nozzles.

An ignition-suppressing tape for sealing cut edges of polymer panels, the tape having a backing strip and a sealant strip that is disposed on a portion of a surface of the backing strip, and a pressure sensitive adhesive is disposed on other portions of the same surface of the backing strip.

A system. The system includes one or more self-sealing panels and a cap member. The one or more self-sealing panels substantially cover an exterior surface of a liquid container. The cap member covers at least one of the following: one or more portions of the exterior surface of the liquid container; and an exterior surface of at least one of the one or more self-sealing panels.

A method of fire suppression may include injecting a reactive agent into a reaction zone to produce a catalytically active species for fire suppression and conveying the catalytically active species to a fire to catalytically interfere with flame chemistry of the fire. Fire in a fuel tank may be suppressed by injecting the reactive agent into a convective flow of a mixture of fuel and oxidizer in a fuel tank, the reactive agent reacting in the fuel tank to release a species which catalytically interferes with flame chemistry to suppress fire in the fuel tank. Fire at an airplane crash may be suppressed by releasing the reactive agent from the container at the crash site to produce an active species to catalytically interfere with a fire at the crash site.

A foam production method includes mixing liquid nitrogen with a foaming material to produce foam. A gas is produced in situ from liquid nitrogen. As the ratio of the volume of the gas produced by gasification of liquid nitrogen to the volume of the liquid nitrogen is relatively high, when a large gas supply flow is needed to generate a large foam flow, a liquid nitrogen storage device of a small volume can be used instead of bulky air supply devices such as high-pressure gas cylinders, air compressors, air compressor sets and the like, reducing the volume of the air supply device. In addition, the liquid nitrogen used in foaming will release nitrogen gas after the foam blast, such that the nitrogen is also able to inhibit combustion on the surface of burning materials, accelerating the extinguishing of the fire.

A system is disclosed for providing inerting gas to a protected space, and also providing electrical power. The system includes an electrochemical cell comprising a cathode and an anode separated by a separator comprising a proton transfer medium. Inerting gas is produced at the cathode. A fuel source comprising methanol or formaldehyde or ethanol and a water source are each in controllable operative fluid communication with the anode. A controller is configured to alternatively operate the system in a first mode of operation where water is directed to the anode fluid flow path inlet and electric power is directed from a power source to the electrochemical cell, and in a second mode of operation in which the fuel is directed from the fuel source to the anode fluid flow path inlet and electric power is directed from the electrochemical cell to the power sink.
