Triangle Shirtwaist Factory fire The Triangle Shirtwaist Factory fire in Manhattan, New York City on March 25, 1911 was the deadliest industrial disaster in the history of the city, and one of the deadliest in US history. The fire caused the deaths of 146 garment workers – 123 women and 23 men – who died from the fire, smoke inhalation, or falling or jumping to their deaths. Most of the victims were recent Jewish and Italian immigrant women aged 16 to 23; of the victims whose ages are known, the oldest victim was Providenza Panno at 43, and the youngest were 14-year-olds Kate Leone and "Sara" Rosaria Maltese. ... Because the owners had locked the doors to the stairwells and exits – a then-common practice to prevent workers from taking unauthorized breaks and to reduce theft – many of the workers could not escape and jumped from the high windows. The fire led to legislation requiring improved factory safety standards and helped spur the growth of the International Ladies' Garment Workers' Union (ILGWU), which fought for better working conditions for sweatshop workers.Whenever the current GOP rails against intrusive government regulation of the "free market", this is the example I cite. I WANT my government to protect me from rapacious, predatory capitalism!
