Abstract
A fire fighting method for extinguishing an elongated object includes spraying a first water-based spray (1a) and a second water-based spray (2a) with a first spray nozzle (1) and a second spray nozzle (2) to the immediate vicinity of the object in such a way that the first spray is directed towards the underpressure of air generated by the second spray nozzle. To enable efficient extinction with a small number of spray heads without causing high temperature gradients at various points on the surface of the object to be extinguished, the second spray (2a) is sprayed towards the underpressure of air generated by the first spray nozzle, and the first and the second spray are sprayed at least approximately in the direction of a longitudinal axis the of the elongated object in such a manner that the sprays are sprayed mainly in opposite directions and that the first and the second spray form a continuous spray path.
