Abstract
Magnesium fires require early fire extinguishment due to impulsive and rapid-fire expansion that makes difficult fire fighting. For this reason, efficient early fire fighting and appropriate prevention of fire spread are considered mainly as significant fire extinction measures. However, there is a limit to developing tools for metal fire fighting, such as devices, facilities, and fire extinguishing agents, due to a lack of regulatory instruments in South Korea. It often generates challenges to early fire fighting implementation by fire responders. Thus, the aim of this study is to investigate a measure for securing the efficiency of early fire fighting in magnesium. This study identified the applicability of the metal fire extinguisher used in the United States for magnesium fire through a performance test of a fire extinguishing agent for metal fire. Moreover, we implemented a free burning experiment using magnesium powder to compare varying combustion and extinction process that could occur during applying metal fire extinguishers. Finally, this study suggests measures of the use and application of metal fire extinguishers for magnesium.
