An airport crash tender is a specialised fire engine designed for use at aerodromes and airports in aircraft accidents.Airport Crash Tenders are extremely powerful machines. They offer relatively good acceleration, are able to negotiate rough terrain outside the runway and airport area, carry large capacities of water, and fire fighting foam, are fitted with powerful high-capacity pumps, and water/foam cannons and capable of delivering firefighting media over long distances.Newer ARFF vehicles also incorporate Twin Agent nozzles/injection systems to inject a stream of Purple-K dry chemical into the AFFF foam stream "knocking-down" the fire faster. Some also have Halotron tanks with handlines for situations that require a clean agent to be utilized. These features give the airport crash tenders a capability to reach an airplane rapidly, and rapidly put out large fires with jet fuel involved.Some tenders have an elevated extended extinguishing arm, giving a possibility to raise a water/foam cannon into the height of approx. 10 - 20 meters. that can puncture through superficial structures of an aeroplane to fight a fire inside the fuselage.
