8. The Triangle Shirtwaist Factory Fire
The industrial disaster in New York killed 146 and injured 71 workers on March 25, 1911, when a fire broke out and consumed the Triangle shirtwaist factory. The factory occupied the eight, ninth, and tenth floor, and many were unable to escape because the doors have been locked by the owner to prevent theft. This disaster triggered a mass movement in the United States as people requested safer working conditions.
