A method of preserving a building or similar asset (16) from destruction by a bushfire is disclosed. The method includes the step of shortly prior to the arrival of the bushfire at the asset or building (16), spraying the exterior of said asset or building (16) with a water-based fire retardant (17) ejected from a nozzle (10) located above the asset or building (16) and mounted on a helicopter (1) carrying the water-based fire retardant (17).

An extinguishing system and method for extinguishing fires. The extinguishing system includes-a pump system for pumping extinguishing agent; one or more nozzles connected operatively to the pump system for the purpose of spraying extinguishing agent at a source of fire; a supply or inlet arranged on the pump system for the purpose of supplying extinguishing agent to the pump system; an extinguishing conduit with an extinguishing length arranged on the pump system for the purpose of supplying extinguishing agent to the at least one nozzle; and an extinguishing controller provided with an input system for inputting system data, including data about the extinguishing conduit, the pump system and the at least one nozzle. The extinguishing controller is configured to determine with the system data an operating pressure at or close to the at least one nozzle and thereby control the pump system.

A spray jet discharging device of long range, whose function is based on the production of a powerful air stream with liquid droplets dispersed therein, the maximum velocity of the spray jet being at least 300 km/h. The air stream is produced by a centrifugal fan with a spiral housing (1). The device is mainly used for fire extinguishing. It may be mounted at fixed points or on land vehicles via a suitable support for the fan, which enables both rotation of the spray jet beam in the horizontal plane, and changing of its inclination angle in the vertical plane. It may be remotely controlled (10) or manually operated (60). There is also a version of the device for aerial fire-fighting operations (90), configured to be suspended from an aircraft, e.g. a helicopter, and a device for portable use (1 10), which can be carried by a fireman.

There is provided a mobile firefighting unit comprising a container having a reservoir portion and a utility portion. The reservoir portion comprises a reservoir for storing a fluid. The utility portion comprises a main pumping station in fluid communication with the reservoir, and a mobile pumping station connectable to the main pumping station through a hose extending outside the container. The mobile pumping station is deployable for firefighting purposes. A heating system is also positioned within the container for heating the interior of the container. A lighting system provides lighting for the interior of the container. The mobile firefighting unit is readily and quickly available for rapid deployment in a fire scenario under various climate conditions.

A water station consisting of a large water tank or bag with a plurality of dangling appendages for lowering toward the ground. These appendages include heat sensors and sprayers, and one or more may be capable of connecting to a fire fighting truck, water tank, fire hydrants, or other pieces of equipment. One or more appendages may also include a bag containing fire-fighting safety gear or ground-based hoses for fighting fires. Cameras and other sensors provide constant feedback to the pilot of the aircraft, such as a helicopter, deploying the water station.

Described are portable fire extinguishing systems for efficient and rapid fire suppression.
