The Large Hadron Collider (LHC), a 27 kilometer (17 mile) long particle accelerator straddling the border of Switzerland and France, is nearly set to begin its first particle beam tests. The European Organization for Nuclear Research (CERN) is preparing for its first small tests in early August, leading to a planned full-track test in September - and the first planned particle collisions before the end of the year. The final step before starting is the chilling of the entire collider to -271.25 C (-456.25 F). Here is a collection of photographs from CERN, showing various stages of completion of the LHC and several of its larger experiments (some over seven stories tall), over the past several years.

Seems their first injector tests were/are being done August 9/10. Ahh found the schedule........
*****************
Schedule Outline
* End of July: The LHC is expected to be cooled down. The experiments are requested to have their beam pipes baked out.
* Early August: The experimental caverns will be closed after the caverns and tunnel have been patrolled. Safety tests will then be performed. From then on the controlled access system will be fully activated. At this stage an Injection Test into sector 23 is planned.
* Early September: First particles will be injected, and the commissioning with beams will start.
* It is expected that it will take about 2 months to have first collisions at 10 TeV centre of mass energy.
* Energy of the 2008 run: Agreed to be 10 TeV. The machine considers this to be a safe setting to optimize up-time of the machine until the winter shut-down (starting likely around end of November). Therefore, simulations can now start for 10 TeV.
* The winter shut-down will then be used to commissioning and train the magnets up to full current, such that the 2009 run will start at the full 14 TeV design energy.
The 450 GeV Calibration Run planned for November 2007 which aimed to establish first beam collisions at a centre of mass energy of 0.9 TeV has been put on ice. However, collisions at 450 GeV are planned as we go for 7 TeV in 2008 and the requisite commissioning described above is still valid. (Discussion and potential performance.)
The sector test is due to be performed 9/10 August.

I believe they state 'small chance of a black hole developing' and other than that it's much like the nuclear bomb... they weren't really sure exactly what would happen when they set it off.

The main purpose of this facility is to produce antimatter and black holes. A terrorist would need only half of a gram of antimatter to be equally destructive as the Hiroshima bomb. If CERN’s antimatter factory were to blow up today it would only affect the regions bordering France and Switzerland. But if CERN were to produce just one stable black hole , it could destroy the world. Surprisingly, the United States of America, through the National Science Foundation and the Department of Energy, will be funding over $1 Billion Dollars towards this French experiment into creating potentially devastating black holes.
These black holes, the densest matter in the universe, will plummet to the very core of the earth, then, slowly at first, growing one particle, one quark at a time, but at an ever accelerating rate. Scientists have estimated that a stable black hole at the center of the earth could consume not only France but the whole planet in the very short time span of between 4 minutes and 30 seconds and 7 minutes.
That age-old question: Will our planet disappear in the twinkling of an eye? - Now becomes a probability if and when the CERN facility is allowed to go on-line in 2008.

According to this review by 'neutral' scientists there is no risk beyond the everyday normal things which nature presents us.

IMPORTANT NOTE: On Tuesday, March 27, 2007, there was a devastating explosion deep in the tunnel at the CERN particle accelerator complex that actually blew a 20 ton magnet right off its mountings. The explosion filled the tunnel with helium and forced a mass evacuation of the facility.
While the facility was supposed to go online during the summer of 2007, the new startup is tentatively summer of 2008 after 17 miles of magnets have been repaired or replaced. This explosion, to those of us who count ourselves among the worried masses, appears to be an ominous foreshadowing of what could eventually become the Second-Coming of the Big Bang...
Even Dr. Lyn Evans, who heads the accelerator project at CERN, said the explosion had been potentially very dangerous. "There was a hell of a bang, the tunnel housing the machine filled with helium and dust and we had to call in the fire brigade to evacuate the place," he said. "The people working on the test were frightened to death but they were all in a safe place so no-one was hurt."
An investigation by the researchers found that basic math flaws had caused the explosion -- which gives one pause in contemplating how much faith can bestowed upon 6,000 scientists who can overlook basic math mistakes. Not only was this mistake made in the original design phase, but it was also missed on four engineering reviews carried out over a period of four years. The director of Fermilab, Pier Oddone, blithely wrote about the disaster stating that they had caused "a pratfall on the world stage". A pratfall ? Should these Keystone-scientists be entrusted with the fate of the world in their hands?
