The unification of the Fire Department, which took place in 1898, would pave the way for many changes. In 1909 the Fire Department received its first piece of motorized fire apparatus. On March 25, 1911 a fire in the Triangle Shirtwaist Company killed 146 workers, most of whom were young female immigrants. Later the same year the fire college was formed to train new fire fighters, and in 1912 the Bureau of Fire Prevention was created.
