When Nicholas Adrian Revetta of suburban Pittsburgh died in an explosion at a U.S. Steel plant on Sept. 3, 2009, his death did not make national headlines.
No hearings were held into the accident that killed him. No one was fired or sent to jail.
The 32-year-old contract laborer, who left behind a wife and two young children, was one of the 4,551 people killed on the job in America in 2009 -- a number that eclipsed the total number of U.S. fatalities in the nine-year Iraq war. Combined with the estimated 50,000 people who die annually of work-related diseases, it's as if a fully loaded Boeing 737-700 crashed every day.
