Hydrogen is getting more and more because of protection and prevention for global warming, the bigger and wider the usage. Hydrogen is a key enabler for achieving carbon neutrality, it will predicts a six-fold increase from today by 2050. Much amount, new process and new usage of Hydrogen, however, many result new concept of safety hazards in all handling-manufacturing, storing, using even in the H2FS(Hydrogen reFueling Station). In this study, we will present example to compressor(diaphragm type) of H2FS and consider ways to improve safety in order to prevent hydrogen explosion accidents and improve safety. The Ex-HAC(Explosion Hazardous Area Classification) of hydrogen facilities is not only fundamental but also highly critical, aimed at preventing accidents in advance and improving unstable situations. Based on this, it is hope to be useful to experts in related fields who are interesting with the preventing explosion accident.
