Healthier Workers. Safer Workplaces. A Stronger America.


As OSHA celebrates 40 years of protecting workers, we also remember the labor pioneers, safety advocates, community leaders and ordinary workers whose vision for a stronger America laid the foundations for the laws that keep workers safe and healthy today. The 100th anniversary of the Triangle shirtwaist factory fire, which killed 146 workers in a New York City garment factory, marks a century of reforms that make up the core of OSHA's mission. Use this page to learn more about a tragic event that led to a "general awakening" that continues to drive OSHA's commitment to workers.

"The worst day I ever saw"

One hundred years ago on March 25, fire spread through the cramped Triangle Waist Company garment factory on the 8th, 9th and 10th floors of the Asch Building in lower Manhattan.

The building had only one fire escape, which collapsed during the rescue effort. Long tables and bulky machines trapped many of the victims. Panicked workers were crushed as they struggled with doors that were locked by managers to prevent theft, or doors that opened the wrong way.
