What incident in March 1911 resulted in the loss of 146 lives and significant changes in fire safety legislation?

The Triangle Shirtwaist Factory fire, which occurred in March 1911, is a pivotal event in the history of fire safety legislation due to its tragic outcome and the subsequent public outcry for reform. The fire broke out on the top floors of the factory located in New York City, where young immigrant women worked under hazardous conditions. The building had inadequate fire safety measures and exits were locked to prevent theft, which severely limited escape options for the workers.

Consequently, when the fire ignited, many were trapped, leading to the horrific loss of 146 lives. The sheer scale of the tragedy raised awareness about workplace safety and the need for fire safety regulations. In the aftermath, the incident sparked widespread reform, resulting in stronger building codes and fire safety laws designed to protect workers. It catalyzed the establishment of organizations and regulations focused on ensuring better safety standards in workplaces across the United States.

This reform movement fundamentally shaped modern fire safety practices and labor rights, setting a precedent that emphasized the importance of safety measures in preventing future tragedies.
