THE DEFINITION OF FIRE-EXTINGUISHING EFFICIENCY OF INERT FOAM

Abstract

The article deals with the results of inert foam extinguishing. The extinguishing was carried out in 0,7x2,1x0,5 m setting. The efficiency of usage of such extinguishing was established. The results of inert foam extinguishing are better from the results of simple recycling in twice. Inert foam extinguishing is quicker in time. Maximal temperature reduction form 700°C to 400 °С is occurred in the first minute of inert foam extinguishing. The high percentage of CO2 is kept in this process for a long time for environment inertisation. Foam delivery must be carried out despite the disappearance of a flaming fire and continue to lower the temperature below 150 0 C in the combustion zone, at least 3 minutes.
