MRI facility

[mshields]

I've done a fair amount of electrical designs for MRI's in hospitals. I'm now being asked to do one in a facility that is to have no generator and further being informed that I don't need it.

I agree that the equipment itself doesn't need it and that it doesn't meet the criteria of chapter 4 of NFPA 99 for a Cat 1 or 2 system. Lighting can be via battery packs.

What about exhaust fans that come into play in the event of a helium gas leak?

What about an alarm panel associated with same?

Helium isn't poisonous. It's no more deadly than FM-200 or Halon. The only thing wrong with it is that it isn't oxygen. We don't have to put in generators for those fire suppression systems either.
