3. Importance of Inherent Safety in Human Machine Interface Environment Yutaka Ishida l 2 Alfred Neudorfer 2 Koichi Futsuhara 2 Toshihiro Fujita 1 Abstract In HMI Human Machine Interface environment where operators control various machines on the factory floor there always exist risk for the operators to encounter dangerous situations In order to avoid such risks International Safety Standards such as IEC ISO clearly state that inherent safety design is of prime Importance Especially at tmes when operators need to be interactimg with machine operations such as setting up teaching process changeover failure treatment repairing and maintenance ergonomic cons1deration should be fully implemented This paper describes the importance of inherent safety by the study of actual operational flow of machines Keywords Inherent safety Risk assessment HMI Enabling device ISO12100 ISO14121 1 FA Factory Automation HMI Human Machine Interface
