1. A method for fire fighting, comprising the steps of:
- delivering extinguishing liquid using pressure charged energy;
spraying said extinguishing liquid in the form of concentrated fog sprays with strong penetrating power from spray heads and a high operating pressure of about 100-300 bar in order to at least suppress a fire; and
thereafter spraying said extinguishing liquid in the form of spread fog-like sprays from said spray heads and a lower operating pressure that is lower than said high operating pressure in order to effect effective heat absorption and control of said fire.

Abstract
The object of the invention is to provide a new method for extinguishing fires. The method is advantageously used for fighting fires in engine rooms and similar spaces. According to the method, the fire is extinguished or at least suppressed by means of concentrated fog sprays with strong penetrating power, by utilizing high operating pressure, which is gradually decreased for the provision of spread fog-like liquid spraying providing for effective heat absorption and control of fire. The extinguishing liquid is preferably delivered to spray heads (43, 44, 45) by using hydraulic accumulators (41, 41a).

-
delivering extinguishing liquid using pressure charged energy; spraying said extinguishing liquid in the form of concentrated fog sprays with strong penetrating power from spray heads and a high operating pressure of about 100-300 bar in order to at least suppress a fire; and thereafter spraying said extinguishing liquid in the form of spread fog-like sprays from said spray heads and a lower operating pressure that is lower than said high operating pressure in order to effect effective heat absorption and control of said fire; wherein said delivering uses a number of hydraulic accumulators connected in parallel and discharged in cycles; wherein said hydraulic accumulators are charged between said cycles; and wherein said extinguishing liquid is delivered from a pressure of 5 to 10 bar through said spray heads during said charging of said hydraulic accumulators.
