Early on the morning of September 3, 2009, Nicholas Adrian Revetta left the Pittsburgh, Pennsylvania, suburb of Pleasant Hills and drove 15 minutes to a job at US Steel's Clairton Plant, a soot-blackened industrial complex on the Monongahela River. He never returned home.
Revetta was working as a laborer for a US Steel contractor that had employed his father, at the same plant that employed his brother. Shortly before 11:30 a.m., gas leaking from a line in the plant's Chemicals and Energy Division found an ignition source and exploded, propelling him backward into a steel column and inflicting a fatal blow to his head. Thirty-two years old, he left behind a wife and two young children.
