Abstract (en)
The invention relates to a method for firefighting using compressed air foam (CAF), comprising the following steps - detecting a fire, - feeding a pressure actuated valve (6) with CAF, - opening said pressure actuated valve to a known extent, - projecting said CAF on the fire, - measuring a pressure exerted by the CAF downstream of said valve (6), - controlling a degree of opening of said valve (6) on the basis of the measured values of said CAF flow pressure.
