I had an MRI scan recently, and the room had a very, very heavy steel
door that appeared air tight. I assume that was to protect the rest of
the building if the helium boiled?


If this was the door through which you entered it may have been just to
maintain RF shielding. They don't plan on the patient being left to
suffer if quenching leads to increased pressure in the scan room, or for
any window to the control room to blow out explosively.
