The Asch Building at the corner of Washington Place and Greene Street in Greenwich Village was a ten-story loft building completed in 1901. Its eighth, ninth, and tenth floors were occupied by the Triangle Waist Company — popularly the Triangle Shirtwaist Company — manufacturing the high-collared white blouses (shirtwaists) that were the standard American women’s office wear of the period. The factory employed approximately 500 workers, predominantly Jewish and Italian immigrant women between 16 and 23 years old. The standard work day was 9 hours; the standard work week was 6 days; the standard hourly wage was about 13 cents (about $4.40 in 2025 dollars).

In November 1909 and February 1910 the Triangle workforce had been a substantial participant in the Uprising of the 20,000 — the New York garment-workers’ strike that had won most New York garment shops a closed-shop union contract with the International Ladies’ Garment Workers’ Union (ILGWU). The Triangle owners Max Blanck and Isaac Harris had successfully resisted the union demand. Their factory continued operating without an ILGWU contract.

Their factory’s safety practices were standard for the unorganised garment shops of the period and substantially below the contracted shops. The most relevant practice for the events of 25 March 1911 was that the exit doors of the eighth and ninth floors were locked from the outside during working hours, with a single keyholder at each floor.

The stated reason was to prevent unauthorised exits during shift breaks (which Blanck and Harris suspected of allowing workers to steal blouses or fabric). The practical effect, during the fire that began on 25 March 1911, was that approximately half of the workers on the affected floors could not reach the staircase.

4:40 p.m.

The fire began at approximately 4:40 p.m. on Saturday 25 March 1911, ten minutes before the end of the shift, in a scrap-cloth bin on the eighth floor against the Washington Place wall. The probable cause was a discarded cigarette or match — both were prohibited but neither rule was enforced. The bin contained approximately two months’ accumulation of fabric scraps, paper patterns, and dust. The fire was burning at full intensity within ninety seconds of ignition.

The eighth floor’s foreman telephoned the warning to the tenth floor (the executive floor where Blanck and Harris worked). He could not reach the ninth floor — the telephone line to the ninth floor was not operating that afternoon.

The eighth-floor workers escaped via the Greene Street staircase, which was unlocked, and via the building’s two passenger elevators, which were operating for about ten minutes after the fire began. Approximately 240 of the 280 eighth-floor workers escaped.

The tenth-floor executives, warned by the telephone, escaped up to the roof and across to the adjacent building. All except one survived.

The ninth floor was not warned. The workers there first knew of the fire when smoke began rising up the stairway and through the floor seams. By that point — approximately 4:43 p.m. — the eighth-floor flames had reached the Washington Place staircase. The Greene Street staircase was the only escape route for the ninth floor and that staircase rapidly became impassable as flames moved up.

Most of the ninth-floor workers ran for the Washington Place door. The door was locked. The keyholder — a foreman named Bernstein — had already left the floor and was on the elevator going down. The crowd at the locked door piled four and five deep and could not push the door open. Other workers ran to the building’s external fire escape, which had been constructed below code and collapsed under the load of approximately twenty bodies, dropping them ninety feet onto the courtyard pavement.

The remaining workers had three options: jump from the ninth-floor windows, wait in the room for the fire to reach them, or try the elevators. The elevators — which had stopped running at approximately 4:50 p.m. when the elevator operators had been ordered out by the building manager — were no longer reaching the ninth floor.

Sixty-two workers jumped from the ninth-floor windows. The fire department’s life-net pulled out in the street below could not hold the impact of two workers landing simultaneously. The first life-net was torn through within ninety seconds of being deployed.

The fire was extinguished at approximately 4:58 p.m. — eighteen minutes after it had begun. The death toll was 146: 123 women and 23 men, between ages 14 and 43. Most of the dead were Jewish or Italian immigrants. The youngest victims were two 14-year-olds — Kate Leone and Rosaria Maltese — and an 11-year-old at a contested age listed in the company records as 15 (Vincenza Cernzone). The oldest was Providence Panno, 43.

What followed

Blanck and Harris were charged with first- and second-degree manslaughter in December 1911. The charge specifically concerned the locked Washington Place door. The trial ran from 4 December to 27 December 1911. The defence argued that the company owners could not be proved to have personally given the order to lock the specific door on the specific day. The jury returned a not-guilty verdict on 27 December 1911 after approximately two hours of deliberation. The owners walked out of the court.

A subsequent civil suit produced a 1914 settlement of $75 per dead worker paid to the families.

The political consequence was substantial. New York State Assembly Speaker Al Smith and Senate Majority Leader Robert Wagner organised the New York Factory Investigating Commission (1911-1915) under the staff direction of Frances Perkins — who had been having tea on Washington Square at 4:40 p.m. on 25 March 1911 and had witnessed the workers jumping. The Commission’s recommendations produced thirty-eight New York state factory-safety laws between 1912 and 1914, including specific requirements for fire-escape design, sprinkler systems, exit door specifications, and child-labour limits. The legislation was the most substantial state-level workplace-safety reform package in any American state to that date.

Frances Perkins went on to become the first United States Secretary of Labor under Franklin D. Roosevelt — appointed in 1933 — and the principal administrative architect of the 1935 Social Security Act and the 1938 Fair Labor Standards Act. She publicly identified the Triangle Shirtwaist fire as the moment that had defined the rest of her career.

The Asch Building still stands. It was renamed the Brown Building in 1929 and was acquired by New York University in 1930. It is now the NYU Department of Biology. A bronze plaque on the Washington Place side records the date and the death toll. New York City fire marshals attend an annual commemoration at the building on 25 March each year. The 113th commemoration was held in 2024.

The locked door had killed 146 people in eighteen minutes. The legislation passed in response saved an unknown but substantial number more over the following century.
