I would just like to point out that this is a particle accelerator. It's a really big one... but that's it. There is certainly a chance of quantum particles fluctuation in such a way that could be catastrophic, but that's always a risk. In fact you're much more likely to:
Be killed by an albino ferret.
Get hit by lightning, survive, get hit again, and then as your getting up get his a third time which does you in.
Have a lead pipe that it in particle fluctuation suddenly appear inside of you.
Spontaneously combust while getting dressed.
And I'm totally serious, by the way. This particle accelerator is no more dangerous than the 12 or so albino ferrets running around so maybe we should eliminate them first.
