The Triangle Shirtwaist Fire was the deadliest workplace accident in New York City's history. On March 25th, 1911, a deadly fire broke out in the Triangle Shirtwaist Factory in New York's Greenwich Village. The blaze ripped through the congested loft as petrified workers -- mostly young immigrant women -- desperately tried to make their way downstairs. By the time the fire burned itself out, 146 people were dead. All but 17 of the dead were women and nearly half were teenagers. The ensuing public outrage forced government action. Within three years, more than 36 new state laws had passed regulating fire safety and the quality of workplace conditions. The landmark legislation gave New Yorkers the most comprehensive workplace safety laws in the country and became a model for the nation.
