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 (S1) IS WITHIN A SECOND MEDIUM MIST SPRAY (S2) AT LEAST AT OR NEAR THE SPRAYING POINT. DURING THE FORMATION OF THE SPRAYS (S1, S2), THE MEDIUM IS SET INTO A SWIRLING MOTION AT LEAST BEFORE THE DISCHARGE OPENING (5, 13) OF THE NOZZLE USED TO FORM EACH SPRAY (S1, S2) AND/OR AT LEAST BEFORE THE SPRAYS (S1, S2) ARE MIXED WITH EACH OTHER, AND THAT THE SWIRLING DIRECTIONS OF THE MEDIUM IN DIFFERENT SPRAYS (S1, S2) ARE OPPOSITE TO EACH OTHER, WHEREBY A PREFERABLY HOMOGENEOUS MIST SPRAY SPREAD OVER A LARGE AREA IS ACHIEVED.
