Abstract
New ozone-friendly fire extinguishing mixtures based on iodinated halons are proposed in the present paper. They act on a flame both chemical inhibitor and diluent. It was obtained that mixture CF3H+CH3I has value of minimum fire extinguishing concentration (MFEC) which is less on 20 % (vol.) or on 16 % (mass.). The new method of determination of fire extinguishing concentrations ("cylinder" method) is proposed in this paper. Adequacy of the new method was confirmed by results of large-scale experiments. Experimental results show that values of MFEC for CF3H, C2F5H and CO2 are less 34, 16, and 30 % respectively, when MFEC was determined according to "cylinder" method.Citation
