Watch Frontline Season 26 Episode 3 Online

Five years ago, FRONTLINE and The New York Times joined forces to investigate death and dismemberment in one of America's most dangerous industries -- the iron pipe foundry business. One company stood out, the McWane Corporation. It had more health and safety violations than all of its competitors combined, and there were a number of environmental violations as well. In the five years since our original broadcast, federal prosecutors obtained indictments against and juries convicted the company in five cases in four states. Today McWane says it has made a dramatic turnaround and that worker safety and environmental protection are now high priorities. FRONTLINE revisits its original broadcast with correspondent Lowell Bergman who then reports on what has changed at McWane and whether the company has become a less dangerous business.
