Quenching MRI magnets can suffocate people in the room they quench, and potentially the entire floor. I don’t know about a whole building, but just because something can dissipate doesn’t mean it can’t do damage in the meantime.

Not true - the whole point of burst discs etc in MRIs is so that if a quench happens, the patients and any technicians in the room survive

Venting even a full MRI's worth of LHe (~1500l) as most will make you a little lightheaded for a few minutes

The risk of death from quench events is effectively non-existent
