A method of delivering an aqueous medium in case of fire hazard, an aqueous medium nozzle for reducing fire hazard and a vehicle for reducing fire hazard

摘要

A method, a nozzle and a firetruck for delivering an aqueous medium such as water in case of fire hazard, wherein - a jet of gas is provided from a gas nozzle aimed towards a target location, - the aqueous medium is provided above the jet of gas. To deliver aqueous medium more effectively to a target location, the aqueous medium is distributed over the jet of gas emanating from the gas nozzle having an elongated aqueous medium outlet opening for aqueous medium as the outlet opening, said elongated aqueous medium outlet opening having a largest thickness T and an effective width W wherein ratio R equals W/T and is at least 1.5, the stream of aqueous medium having a largest thickness divided by an effective width equal to R at said outlet opening.
