Sometimes the rules of business change only after tragedy forces the issue.

On March 25, 1911, a fire broke out at the Triangle Shirtwaist Factory in New York City. Within minutes, the blaze trapped hundreds of garment workers inside the upper floors of the Asch Building. Locked doors, narrow stairways, and inadequate fire escapes turned the factory into a deadly trap. By the time the fire was over, 146 workers had died.

The disaster shocked the public and drew national attention to the working conditions inside rapidly expanding industrial factories. Investigations revealed widespread safety failures that were common across many workplaces at the time.

In response, New York created a factory investigation commission that led to sweeping new safety regulations. Over the following years, these reforms influenced building codes, fire safety standards, and labor protections across the United States.

The Triangle fire did more than expose dangerous conditions. It accelerated the creation of workplace safety rules that still shape American business today.
