You know what a panic bar looks like. Usually it’s the big horizontal bar across a door in an office or school. Panic bars are also known as exit devices or crash bars. The purpose of a panic bar is to allow a quick exit from a building in the event of a fire or another kind of emergency. Panic bars are required on buildings in several countries. The panic bar was invented by Carl Prinzler with his neighbor Henry DuPont. The idea came from the Iroquois Theater Fire in Chicago in 1903. The blaze took nearly 600 lives in 20 minutes. Those who attempted to escape through the fire exits had to try to open unfamiliar doors that impeded their exit. Prinzler devoted himself to the panic bar to make sure the disaster would never happen again. The panic bar was sold by the Von Duprin Company and remains in use today.
