Brooklyn at one time had it's own Fire Department.
The Brooklyn Fire Department ( B.F.D.) was organized on September 15, 1869 
with 13 Engines and 6 Ladders,which were Engines 1 (Engine 201 today) 
through 13 and Ladders 1 (Ladder 101today) through 6.

There were two major reorganizational dates that involved the Brooklyn and 
Queens engine and ladder companies.

January 28, 1898 merged with the FDNY

January 1, 1913 The second major reorganization 

Brooklyn and the Long Island City Fire Depts. merged with the FDNY on 
January 28, 1898. To avoid confusion with the companies in Manhattan 
and the Bronx, the companies in Brooklyn and Queens were renumbered 
on October 1, 1899. 
One hundred numbers were added to the engines and fifty number were 
added to the ladder companies. The second major reorganization came 
on January 1, 1913. Again one hundred numbers were added to the 
engines and fifty numbers were added to the ladder companies. 
Ladder 8 became Ladder 58 which became Ladder 108. 
Engine Company 16 of the Brooklyn Fire Department became Engine 116
