The Triangle Shirtwaist Factory fire in New York City on March 25, 1911, was the deadliest industrial disaster in the history of the city of New York and resulted in the fourth highest loss of life from an industrial accident in U.S. history. The fire caused the deaths of 146 garment workers, who either died from the fire or jumped to their deaths. Most of the victims were recent Jewish and Italian immigrant women; the youngest were two fourteen-year-old girls. Many of the workers could not escape the burning building because the managers had locked the doors to the stairwells and exits. People jumped from the eighth, ninth, and tenth floors. The fire led to legislation requiring improved factory safety standards and helped spur the growth of the International Ladies' Garment Workers' Union, which fought for better working conditions for sweatshop workers.
