A method for reducing the adverse effects of a fire, in which method smoke and combustion gases are removed from a space by spraying through at least one first spray head ( 2 ) a mist of a medium into a duct part ( 1 ) leading away from the space so as to generate a suction from the space into the duct near the orifice ( 4 ) of the duct ( 1 ). In a first step, the first spray head ( 2 ) is activated and, when necessary, a connection is opened from the space into the duct part ( 1 ) via the orifice ( 4 ) of the duct part by opening a shutter element ( 5 ) and, in a second step, the connection from the space into the duct part ( 1 ) is closed by means of the shutter element ( 5 ) at least when the temperature of the combustion gases and/or smoke exceeds a predetermined value in the duct part or in its vicinity and, when necessary, the spraying through the first spray head ( 2 ) in the duct part ( 1 ) is stopped.
