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.

The present invention discloses a fire extinguishing system for a battery pack, including a detection control apparatus, a fire suppression apparatus, and a hydrant water extinguishing apparatus. The detection control apparatus is disposed inside or outside a battery pack. The fire suppression apparatus and the hydrant water extinguishing apparatus are disposed outside the battery pack. The detection control apparatus is connected to the fire suppression apparatus. The hydrant water extinguishing apparatus is connected to the fire suppression apparatus. Beneficial effects: It is ensured that initial fire can be suppressed and later reignition can be resolved, so that fire extinguishing is adequate. Fire is directly extinguished at a core position inside the battery pack. An exhaust filter device gains valuable time after initial fire extinguishing.

The invention includes an air mover device used for fire mitigation and protection. The core component is an air mover unit whose discharge airstream can be positioned using air rudders to provide air flows in optimum directions and capacity to counter unwanted fire progression or to promote fires in cases of back-burns. Additional support components include a power supply, its fuel source, a speed control mechanism for the air mover, an air mover inlet protective screen, a sparger unit to impart suppressant or retardant into the airstream, and instrumentation and controls to ensure function and safety of equipment and personnel. This device can be on a static or mobile platform, towed or self-propelled and can be locally or remotely controlled.

The technology relates to a submersible water lifting assembly and automatic fire fighting system for unmanned platforms having said system (1) that is efficient yet simple to install, energy saving, noise free and economical. The submersible water lifting assembly can comprise a High flow Ratio ejector Pump (30/30A) that utilizes under water arrangements of unmanned platform and enables the fire-fighting system to efficiently lift water from the sea water; using the force of existing water injection system; eliminating the requirement of diesel engine driven pump, for lifting the water. It avoids fire risk of the safety system itself, even in conditions of a large fire, unlike that of the prior art.

An apparatus for containing fires including a fire containment pouch that includes an upper portion and a lower portion, the fire containment pouch is a flame-resistant material. The upper portion includes a pouch section that is coated with an intumescent material and the lower portion including a cuff section. The upper portion and the lower portion juxtaposed one against each other to define an outer containment portion of elongate length from a top of the pouch section and a bottom of the cuff section. The fire containment pouch is adaptable to be pulled inside out thereby transforming the outer containment portion to an inner containment portion and a fastener secured to the bottom of the cuff section to seal an object within the inner containment portion after the fire containment pouch has been pulled inside out.

An additively manufactured article is described. The additively manufactured article comprises a body, a plurality of channels integrated in the body, and an inlet fluidically coupled to at least one of the channels. The additively manufactured article further comprises pressurized fire suppressant in at least one of the channels.

Disclosed herein is a system and process for monitoring and controlling fire suppression systems in commercial kitchens. Repeatedly various components of the fire suppression systems are tested for faults. When a fault is detected in a particular component, the fault is communicated through a communications module associated with the commercial kitchen via the internet to one or more remote servers. Upon receiving information indicating a particular fault, the one or more remote servers acts to alert interested parties of the default.
