Perhaps rather than just causing a black hole, it causes a tear in space-time that expands at the speed of light. By the time you see it, you're already dead.

Of course, there's still the fact that early worlds would be weighted much more heavily, so this is probably about the first instant that you exist. And there's the fact that, if that's true, the LHC wouldn't decrease the expected lifetime of the world by a noticeable amount.
