As the display manufacturing site has grown to the size of about 400 soccer fields, it has become more sophisticated and high-rise, and fire fighting pipes are also being constructed through various designs. Recently, an explosion accident occurred while discharging fire extinguishing water from S Electronics in Pyeongtaek, and the physical and chemical characteristics of the generated mechanism and piping material were studied through the investigation of the cause. Currently, there is no standard for discharge of digestive water by law, and the standard for use of piping is less than 1.2 Less than. White pipes, which are galvanized pipes made of SPP, can be used, and STS 304 pipes can be constructed at 1.2 Less higher. This study investigated the conditions under which hydrogen gas is generated when zinc and stagnant firewater react for a long time in an air pocket inside the white tube. It was studied that it was a definite factor through the reproducibility verification of the experiment, and the reaction time for water and zinc could be predicted through chemical analysis. In addition, there was a delay in emergency dispatch because there was no system or other prevention that could detect accidents in advance. It was also known through research whether rapid detection was possible through the installation of a hydrogen detection system at the digestive water outlet. Through this, it could be suggested to reflect the previous design of the gas leakage detector. It is hoped that this study will allow workers at manufacturing sites and related firefighting to understand the mechanism of hydrogen gas generation in fire extinguishing water pipes, so that there will be no casualties or property damage caused by explosions.
