5. Rana Plaza Collapse
One of the most tragic disasters ever, and on our list of worst construction accidents in history, that took 1,100 lives and injured 2,500 people took place on April 24, 2013, in Bangladesh. The tragedy occurred when the eight-storey Rana Plaza factory, which was dangerously built in the first place, collapsed. It was a garment factory and the event drew attention to the terrible working conditions in this country where a great number of brands produce their clothes. The event led to an increase in salaries afterward, as well as safety inspections.
