In modern society, many materials have been developed for various purposes such as building enlargement, convenience of architecture, and economy. The types of EPS and PUR used in large logistics warehouses are very vulnerable to fire, and it is difficult to know in advance the progress of combustion and the risk of rapid combustion expansion due to external materials. This paper confirmed the generation of flammable vapor due to external sequence of panel types installed in a sealed state, and analyzed the components of mixed gas using gas chromatography. In the mixed gas, gas components such as carbon monoxide, methane, and the like were identified, and it was found that the gas was mixed with oxygen in the air when the external material was deformed by external heat and rapid combustion was expanded. This is to measure the components of smoke generated during fire suppression in large logistics warehouses to identify the combustion status of internal cores and suggest the need to provide information to the safety management of field personnel.
