The Triangle Shirtwaist Company always kept its doors locked to ensure that the young immigrant women stayed stooped over their machines and didn’t steal anything. When a fire broke out on Saturday, March 25, 1911, on the eighth floor of the New York City factory, the locks sealed the workers’ fate. In just 30 minutes, 146 were killed.
