Problems of Fire Extinguishing in Buildings of the Transport Transit Hubs Using Carbon Dioxide and Gaseous Chladones

Abstract

Emergence of the fire inside the transport transit hub (TTH) leads not only to injury and death of passengers and transport workers, but also to destruction of transport facilities. Therefore, solving of such problems as localization and extinguishing fires in TTH buildings is actually. As a result of conducted analysis of the indoor flame suppression process we have received quantitative ratios for calculation of the time and the specific consumption depending on flow rate of extinguishing agent. It is shown that in case of application of gaseous compounds, as well as other extinguishing agents, dependence of the specific consumption on the flow rate passes through the minimum point that allows defining optimum flow rate during extinguishing of combustible materials of different nature.
