The purpose of this study is to identify the fire danger of the electric radiant heating system and check the way how to use it and the problems that could be possible through a actual case. We carry out an experiment to identify the possibility of the fire in the similar condition of the actual fire case. The results of this study are as follows. It is a possible condition to fire if the air blast of the electric radiant heating system is blocked by some combustible materials such as plastic bags continuously. A temperature sensor and a residual current device are necessary to disconnect the power source. It is also necessary to attach a notice in front of the electric radiant hearing system that shows users the fire danger to forbid the possible fire. Fires could be happened by internal defects of the electronic products. However, we can also find many external reasons to happen fires. Therefore, we need to check all reasons to make fires in the scene of a fire.
