Sažetak
This research paper delves into the studies of the fire extinguishers with the combined supply of the foam-water extinguishing agents in an aerosol state used for the extinguishing simulated fires of "A" and "B" classes. The research was done using a mobile module with a 150-liter water tank and a pumping station equipped with a gasoline engine, and a finely atomized foam-water solution (water + foam concentrate) was used as a fire extinguishing agent, while the concentration of foam concentrate in the fire extinguishing agent was 3%, and that of water 97%. Experimental studies were conducted in three series, and each series of studies included three experiments. Thus, during the studies of the 1st series, the simulated fires of an "A" class were extinguished, and the 2nd and 3rd series of studies dealt with the extinguishing of simulated fires of a "B" class. The research data provided the values of the duration of supply of the fire extinguishing agents and their consumption. Using the method of least squares, the root means square values of the duration of supply of the fire extinguishing agent and the consumption of it when supplied by technical fire extinguishing means were obtained according to the research series and the number of the experiment. It has been established that the duration of supply of the fire extinguishing agents by technical fire extinguishing means depends on such factors as the type of fire extinguishing agent, the percentage and type of impurities in its composition, the tactical and technical characteristics of the fire extinguishing agent, the professional skills of the operator and methodical support.
