No apology necessary.

There are emergencies that could happen anywhere, including in an MRI room. Dealing with emergencies, ease of ingress and egress is paramount.

The proposed solutions would hamper access to these rooms during emergencies, putting patients and techs in harms way (the non idiots), in the name of preventing a moron from giving themselves a Darwin award.

I think it would be a net negative, ie. more people would die/get hurt trying to make an idiot proof enclosure.
