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.
