Don't worry! Though black holes may sound scary, microscopic black holes, the type that could hypothetically be produced by high-energy particle collisions such as this, would pretty much instantaneously (in approximately 10-27 seconds) evaporate due to the emission of Hawking radiation, before they could "suck up" anything. Cosmic rays of far higher intensities than what we could produce routinely collide with atoms in Earth's atmosphere, so microscopic black holes could be happening daily in our atmosphere, we just never see them because they're far too small and evaporate instantly.
