A fire engine (or pumper) is the apparatus that carries hose and water to a fire. An engine carries over 3,000 feet of fire hose in various sizes, a 2,000 gallons per minute pump and 500 gallons of water in a tank. Once the tank water is used (which usually takes less than 2 minutes of firefighting), the engine must be connected to an external water source (a fire hydrant).
A fire truck (or hook and ladder) is essentially a giant toolbox. It carries specially trained personnel and tools, which are used for search and rescue, vehicle extrication, structural collapse rescue and several 100 feet of ladders including a 100-foot hydraulic aerial ladder. At fires, a truck’s primary function is to ventilate the structure and perform search and rescue inside the structure.
