Trucks Many fire departments have several different types of fire trucks.
Engines have a large pump that takes water from a fire hydrant or other source.
The pump boosts the pressure of the water and forces it through hoses. Engines carry several sizes of hoses and nozzles. Many also have a small-diameter hose called a booster line, which is wound on a reel. The booster line is used chiefly to put out small outdoor fires. Engines used for fighting grass or brush fires carry a tank of water and such tools as shovels and rakes.
