The biggest problem is that the magnets will "quench", which is what happens when a superconducting electromagnet suddenly stops being superconducting.
There's a lot of energy stored in that magnet, and when it quenches the energy all turns to heat in a very short time. Any remaining helium will flash boil, turning into an explosive expansion of gas, and the thermal shock will seriously damage the machine
Which, in older machines, might happily pump a fuckton of gaseous helium into the room, potentially creating overpressure and squeezing the door shut while people suffocate.
