A fire engine is a vehicle that is designed to help in fighting fires by taking firefighters to the scene and giving them access to the fire, water or other 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.
A turntable ladder (TL) is perhaps the best-known form of special purpose aerial apparatus, and is used to gain access to fires occurring at height using a large telescopic ladder, where conventional ladders carried on conventional appliances might not reach. The name is derived from the fact that the large ladder is mounted on a turntable on the back of a truck chassis, allowing it to pivot around a stable base. To increase its length, the ladder is telescopic. Modern telescopic ladders are either hydraulic or pneumatic. These mechanical features allow the use of ladders which are longer, sturdier, and more stable. They may also have pre-attached hoses or other equipment
