In the video of The Triangle Shirtwaist Factory Fire, it is clear that the cause of so many deaths is environmental factors because a box of cotton wool caught fire but the hose of the fire bucket was rotten, which made it impossible to extinguish the fire in time, and because there were only one of the four elevators in the building. It can be used, and only 12 people can sit at a time, and because the escape stairs are too narrow to go down, the most annoying thing is that the door of the stairs is locked by the manager. These circumstances resulted in 146 people being crushed to death because they were burned, fell from a building, inhaled heavy smoke, and two holders of this garment factory were charged with manslaughter but were acquitted later in the same year. freed. I think this is very unfair to the family of those 146 people because their negligence might even save money.
