A fire engine (also known in some territories as a fire apparatus, fire truck, or fire appliance) is a vehicle designed primarily for firefighting operations. In addition, many fire departments/fire services often employ their vehicles for various other uses including emergency medical services and rescue purposes. The terms "fire engine" and "fire truck" are often used interchangeably but in North America represent different types of vehicles.
The primary purposes of a fire engine include transporting firefighters to an incident scene, providing water with which to fight a fire, and carrying other equipment needed by firefighters. A typical modern vehicle will carry tools for a wide range of firefighting and rescue tasks, with common equipment including ladders, a self-contained breathing apparatus, ventilating equipment, first aid kits, and hydraulic rescue tools.
Many fire vehicles are based on standard vehicle models (although some parts may be upgraded to cope with the demands of the vehicles' usage). They are normally fitted with audible and visual warnings, as well as communication equipment such as two-way radios and mobile computer technology.
The standard fire engine is an apparatus designed primarily for firefighting operations. The primary purpose of the engine is transporting firefighters to the scene, providing a limited supply of water with which to fight the fire, and carrying tools, equipment, and hoses needed by the firefighters. The tools carried on the fire engine will vary greatly based on many factors including the size of the department and what sort of terrain the department must handle. For example, departments located near large bodies of water or rivers are likely to have some sort of water rescue equipment. Standard tools found on nearly all fire engines include ladders, hydraulic rescue tools (often referred to as the jaws of life), floodlights, fire hose, fire extinguishers, self-contained breathing apparatus, and thermal imaging cameras.
