It is considered that the amount of water used to put out fires by the solid stream application is 50 to 200 times the necessary water consumption theoretically calculated.
The fog flow of nozzle pressure 100 psi has been taken as a counter measures to cope with this problem, and it seems to be our urgent need to make good use of the fog application so as to increase the extinguishing efficiency of water and decrease the water damage to property.
We carried on the subject study so as to analyze the extinguishing efficiency of the fog stream on application-range of discharge, angle of discharge, duration of application, etc.
The No.12 Fog nozzle of Tokyo Metropolitan Fire Board Standard was used in our tests, because this nozzle showed the best operational and characteristic features among all the tested nozzles in the last year’s experiments.
