This popped in my head on my way home for work the other day. I guess I'm worried about some scientist somewhere accidentally creating a black hole.
How long will it take for the Earth to be destroyed by a black hole created in a lab?

I don't think man yet has the ability to create a sustainable gravitational force so strong that even light itself cannot escape. And, because I'll die if it happens, I'm not really going to think/worry about it. 
I really don't think it will ever happen, as there isn't even enough matter in the planet to create a black hole.
If an artificial "black hole" were made in a lab, it would just involve stopping light and not the catastrophic gravitational effects. That's about as plain english as I can put it.
This is called an optical black hole. It's artificial, not exactly the same as the real thing (collapsed star).

I remeber a few years ago about the fear of a blackhole being created by the relativistic heavy ion collider, unfounded but cool nontheless. As to what would happen to the earth...umm it would be bad....really really bad. Imagine an empty aluminum can, then fold it on itself over and over again while twisting and stretching it. Thats what would happen to the planet in an instant from our perspective.
Assuming our estimates of the strength of gravity is correct, there is a slight chance the new Large Hardon Collider could produce a sub atomic sized `black hole` that would last for about a trillionth of a second. If ya want to start tinkering with the physics of gravity across extremely short distances, then you wouldnt need as much mass crammed into the confined space to create a black hole. But, the laws of gravity are well formed theories and the short distance schemes are only proposals, not even theory yet....
Some people are also under the impression that a blackhole has infinite gravity, and that a blackhold created here would have anywhere near the same amount of gravity as say, Sagittarius A (BH at center of galaxy). If the sun were to turn into a blackhole right now, it would have the exact same gravitational effect on us. We wouldn't notice a difference in orbit at all. To create a traditional blackhole would require an enormous amount of matter, which we can't simply create out of nothing.

But they stop at the event horizon.

HAHA! Alas, you are correct.
Optical black hole is something different than a traditional one it is just a substance that slow light those super cooled gases or a Bose-Einstein condensate. Light is slowed and the substance is swirled inward faster than the light travles in the substance. There is an event horizon but this is not a black hole in the gravitational sense.
Another "risk" is the negatively charged strangelet (clump of strange quarks) this won't happen either for a number of reasons frequency of creation compared to other positive up down quarks mainly.
