The invention relates to an installation for fighting fire in a space (5) for transportation of lorries, trailers and the like, the space being bounded by a first longitudinal side wall (3); the installation comprising at least two spray heads (1, 2) whereof the first spray head (1) is placed in the space close to the first longitudinal side wall (3) and obliquely directed downwards at an angle ( alpha 1) of 40 to 70 DEG in relation to a vertical plane and the second spray head (2) is placed in the space close to a second longitudinal side wall (4) of the railway carriage opposite the first side wall and obliquely directed downwards at an angle ( alpha 2) of 40 to 70 DEG in relation to the vertical plane, and a drive source (50) for feeding extinguishing medium to said at least two spray heads. In order to fight a fire efficiently in a trailer or the like, the drive source is a high pressure drive source (50) for feeding the extinguishing medium at a pressure of at least 15 bar; the extinguishing medium is a water-based extinguishing medium; and said two spray heads (1, 2) are placed at a height of 3,2 to 4 m above the floor (11) of the space (5) and arranged to spray water-based extinguishing medium at a spread angle ( beta 1, beta 2) of 45 to 120 DEG and comprise at least two nozzles (20, 21) which are placed and directed in such a way that the spray heads at high pressure provide, in the direction in which the spray heads are directed, a mist-like spray with strong penetration power, and a suction at the respective spray head for sucking in flue gases into the spray of extinguishing medium and for enhancing the vaporization of the extinguishing medium.
