Rules Written in Blood

The safety features we take for granted, like unlocked exits and sprinklers, were born from a horrific tragedy. The 1911 Triangle Shirtwaist Factory fire trapped and killed 146 workers, mostly young immigrant women, behind doors their bosses had locked. This single event sparked public outrage, exposing the deadly reality of unregulated workplaces. It directly forced historic changes in labor laws, creating the foundation for the safe working conditions we expect today.
