Water Cannon - Firefighting

Firefighting

Water cannons were first devised for use on fireboats. Extinguishing fires on boats and buildings near the water was much more difficult and dangerous before fireboats were invented. The first fireboat deployed in Los Angeles was commissioned on 1 August 1919. The first fireboat in New York City was Marine 1, deployed 1 February 1891. There may have been other fireboats elsewhere even earlier.

Fire trucks deliver water with much the same force and volume of force as a water cannon, and have even been used in riot control situations, but are rarely referred to as water cannon outside this context.
