INNOVATIVE DEVELOPMENTS AND MODERN METHODS FOR ENHANCING THE EFFICIENCY OF WATER-BASED FIRE EXTINGUISHING SOLUTIONS USING INHIBITORS
Abstract
Problem. The advancement of modern technology has led to the emergence of new materials with heightened fire hazards, such as lithium-ion batteries, biofuels, and explosive mixtures, which pose challenges for extinguishment using traditional water-based agents due to water’s low viscosity, poor wettability, and rapid evaporation, complicating firefighting efforts for classes A, B, C, D, and F by emergency response services. Purpose. The purpose of the study is to analyze the current state of water-based fire extinguishing agents (WFEA) with inhibitors, elucidate methods to enhance their efficiency, evaluate their potential for suppressing modern fires, and provide recommendations for improving fire suppressants. Research methods. The study employs an analytical method involving the processing of scientific publications, experimental data, and patent documentation on the effectiveness of WFEA with inhibitors, including a comparative analysis of their physical and chemical properties. Research results. Based on the review of scientific papers, it was found that the addition of inhibitors such as potassium chloride (KCl, 3–5 %), olighexamethylene guanidine (OMMG, 5 %), sodium chloride (NaCl, 5–10 %), ammonium phosphates (5–10 %), bicarbonates (5–35 %) and nanoparticles (SiO2, Al2O3, 2–5 %) increases the efficiency of the ERS: extinguishing time is reduced by 20–60 %, substance consumption is reduced by 10–40 %, and re-ignition is prevented within 5–24 hours due to cooling, oxygen isolation and chemical combustion suppression; an innovative approach is the development of new formulations (e.g., “dry water” with bicarbonates, WWA with nanoparticles) and technologies for their preparation (ultrasound, mixing). Conclusions. WFEA with inhibitors is a promising solution for extinguishing modern fires, providing environmental friendliness, economy and adaptability, but further research is needed to optimize the compositions and implementation technologies for extinguishing fires of different classes.
