How did the 1911 triangle shirtwaist factory fire promote the argument for worker safety?

The 1911 Triangle Shirtwaist Factory Fire was one of the deadliest fires in US history, as building owners closed the doors to prevent unauthorized breaks or theft; the 146 garment workers were killed by the fire. The owners of the company, Max Blanck and Isaac Harris, were tried and a commission was set up in New York to investigate conditions at the factory; in addition, 200 factories with similar conditions were discovered, reason why 38 new laws were created that regulated the work, in the state of New York; and by 1913 more than 60 protection laws were approved. Fire protection, fire extinguishers, alarm systems and automatic sprinklers became requirements; making New York one of the safest states in terms of fire protection.
