And deadlier, since most work safety deaths are single death, no additional injury situations.  Here at least 5 are dead, and 12 severely injured, and likely more as they dig out the explosion.  It also blew out windows, and shook towns miles away.  

But the likely newsworthy part is going to be the strengthening of the paranoia and the NIMBY action against power generation.  After Three Mile Island you couldn't get a neighborhood to accept nuclear power plants.

Right, most work safety deaths are onesies or twosies.  But here we're talking about an explosion at a natural gas facility.  Think a major refinery fire and I think you'll find the body count goes up quite a bit.  Possibly the only thing that reduced the number of dead was the fact that the facility was still under construction therefore a full production crew wasn't on the site.
