A mass tort is a civil action involving numerous plaintiffs against one or a few corporate defendants. The tort may involve, for example, personal injuries suffered by numerous plaintiffs as a result of a defective product, or a mass disaster in which there were many injured persons, such as an airplane crash, or exposure of a large group of people to toxic chemicals or pharmaceuticals.
Clairton is a city in Allegheny County, Pennsylvania, United States, along the Monongahela River and is part of the Pittsburgh Metropolitan Area. The population was 8,491 at the 2000 census. Under Pennsylvania legal classifications for local governments, Clairton is considered a third-class city. The city was the setting for the movie The Deer Hunter (1978), although the opening scene featuring the "City of Prayer" sign was not actually filmed there (other mill towns in the Monongahela River Valley and elsewhere in the tri-state area were used). That sign was based on the signs in Clairton, but that footage was actually shot in Mingo Junction, OH. It also is home to Clairton Works, the largest coke manufacturing facility in the United States. The Montour Trail, a recreational rail-trail extends from Clairton to Coraopolis, Pennsylvania.
