Abstract
A method for spraying a medium mist, especially a medium mist used in firefighting, over a large area, in which method at least two sprays of medium mist are formed, of which a first spray (S) is within a second medium mist spray (S) at least at or near the spraying point. During the formation of the sprays (S, S), the medium is set into a swirling motion at least before the discharge opening () of the nozzle used to form each spray (S, S) and/or at least before the sprays (S, S) are mixed with each other, and that the swirling directions of the medium in different sprays (S, S) are opposite to each other, whereby a preferably homogeneous mist spray spread over a large area is achieved.
