EMO in my experience is used in the semiconductor manufacturing business to bring everything to a safe condition. I have not seen it used outside the semi industry. It is defined in the SEMI S2 safety standard. I can provide a definition if needed.
Emergency stop and emergency disconnect are, I believe, defined in IEC 60204-1 and NFPA 79.

Subject: [PSES] EMO vs EPO
--All,Is there an official fine point distinction between Emergency Off (EMO), Emergency Power Off (EPO) and Emergency Stop or are they all equivalent and interchangeable terms?To my thinking, if there is a distinction, it would seem that Emergency Stop is related to mechanical hazards or moving parts, EPO is related to electrical hazards and EMO would be a general "catch all" acronym for any type of hazard whether mechanical, electrical, radiation, chemical, etc.Thanks! Doug--
