<p>The invention relates to a method of extinguishing fires in closed or open spaces using water and foam. The method is characterized in that water mist is first produced with the air available in the space without air supply from outside until the temperature in the combustion gases has fallen below a predetermined level or during a predetermined period of time, whereupon foam is produced with the air available in the space without air supply from outside and with a suitable speed for filling the space and extinguishing the fire. The invention also includes a means for performing the method comprising units for producing water mist and foam in the space and a closing or controlling valve (33) which, in dependence upon the temperature in the combustion gases or period of time elapsed from the start of the water mist production, controls the amount of foam liquid added to the water.</p> |
