On the afternoon of March 25, 1911, a fire at the Triangle Shirtwaist Company that began in a rag bin swept through the eighth, ninth, and tenth floors, too high for fire ladders to reach. The fire chief of New York had said that his ladders could reach only to the seventh floor. But half of New York's 500,000 workers spent all day, perhaps twelve hours, above the seventh floor. The laws said factory doors had to open outward. But at the Triangle Company the doors opened in. The law said the doors could not be locked during working hours, but at the Triangle Company doors were usually locked so the company could keep track of the employees. And so, trapped, the young women were burned to death at their work-tables, or jammed against the locked exit door, or leaped to their deaths down the elevator shafts. The New York World reported:
.. . screaming men and women and boys and girls crowded out on the many window ledges and threw themselves into the streets far below. They jumped with their clothing ablaze. The hair of some of the girls streamed up aflame as they leaped. Thud after thud sounded on the pavements. It is a ghastly fact that on both the Greene Street and Washington Place sides of the building there grew mounds of the dead and dying. .. .From opposite windows spectators saw again and again pitiable companionships formed in the instant of death-girls who placed their arms around each other as they leaped.
When it was over, 146 Triangle workers, mostly women, were burned or crushed to death. There was a memorial parade down Broadway, and 100,000 marched.
