The federal Occupational Safety & Health Administration is investigating a trench collapse that briefly trapped a worker in Pittsburgh.
Authorities say 50-year-old Robert Reynolds, of Pittsburgh, was able to dig himself out as crews arrived at the scene Wednesday afternoon.
Crews initially though Reynolds was buried up to his chest while standing in the trench installing sewer lines for an apartment. Instead, Reynolds was knocked down by the moving muck and was able to dig himself out because he was actually in a sitting position and not buried as deeply as it appeared.
Reynolds works for a private contractor in the city, Stadterman Plumbing
