What does fireman do with water?
Using water is one common method to extinguish a fire. Water extinguishes a fire by cooling, which removes heat because of water’s ability to absorb massive amounts of heat as it converts to water vapor. Without heat, the fuel cannot keep the oxidizer from reducing the fuel in order to sustain the fire.
Who is responsible for water hydrants?
Statutory fire hydrants are owned, installed and maintained by the water companies. Private fire hydrants found on private water mains are not the responsibility of the Local Water Company or the Fire and Rescue Service.
