Fire hoses are commonly used to convey water in order to stop a fire from spreading and douse the flames. Attack fire hoses convey water from a fire pump to a fire. Supply line fire hoses bring large volumes of water from a hydrant or other pressurized source to a fire pump so it can be conveyed to an attack hose. Booster fire hoses are primarily used to fight small fires. Pin rack and reel fire hoses are commonly installed in buildings to provide the buildings' occupants with fire hoses for initial fire response in an emergency. Wildland fire hoses are designed for firefighting applications where the hoses will need to be carried long distances over steep or rough terrain to reach a fire.
