Advantages of Water Fog Use as a Fire Extinguisher

Abstract

Due to the consequences of global climate change and complex impacts of civilization, the Earth’s drinking water reserves have started to decrease or become so seriously contaminated in some areas that it is inadequate for human consumption. International research groups and organizations are calling the countries to greater environmental and security awareness. Severity of environmental protection regulations made the usage of environmental friendly fire-fighting materials (water, among others) more important again. In Hungary, fire brigades use drinking water in approximately 90% of their fire-fighting operations. Some recently developed water fog fire extinguisher apparatuses have made special utilization of water available, as their use is friendly to the environment, effective and economical and in comparison with the conventional fire-fighting techniques consume a considerably less amount of water. In my paper I am going to demonstrate and summarize the advantages of water fog fire extinction based on the physical and chemical properties of water.
