An [[airport crash tender]] is a specialized fire engine designed for use at [[aerodrome]]s in [[aircraft]] accidents.<ref name="new-arff">{{cite journal|last1=Petrillo|first1=Alan|date=29 August 2014|title=Protecting Airports with New ARFF Designs and Equipment|url=http://www.fireapparatusmagazine.com/articles/print/volume-19/issue-9/features/protecting-airports-with-new-arff-designs-and-equipment.html|url-status=dead|journal=Fire Apparatus & Emergency Equipment|volume=19|issue=9|archive-url=https://web.archive.org/web/20141228185946/http://www.fireapparatusmagazine.com/articles/print/volume-19/issue-9/features/protecting-airports-with-new-arff-designs-and-equipment.html|archive-date=December 28, 2014|access-date=17 March 2015}}</ref> Some of the features that make the airport crash tender unique are its ability to move on rough terrain outside the [[runway]] and airport area, large water capacity as well as a [[firefighting foam|foam]] tank, a high-capacity pump, and water/foam [[Fire monitor|monitors]]. Newer airport crash tenders also incorporate [[Twin agent fire extinguishing system|twin agent]] nozzles/injection systems that add dry chemical [[fire retardant]] (such as [[Purple-K]]) to create a stream of [[firefighting foam]] which is able to stop the fire faster.<ref name="fr-arff">{{cite journal|last1=Vaccaro|first1=Bob|date=31 July 2008|title=Latest ARFF Apparatus Technology|url=http://www.firefighternation.com/article/apparatus-innovations/latest-arff-apparatus-technology|url-status=dead|journal=FireRescue|issue=August 2008|archive-url=https://web.archive.org/web/20140529020848/http://www.firefighternation.com/article/apparatus-innovations/latest-arff-apparatus-technology|archive-date=May 29, 2014|access-date=17 March 2015}}</ref> Some also have [[gaseous fire suppression]] tanks for electrical fires. These features give the airport crash tenders a capability to reach an airplane rapidly, and rapidly extinguish large fires with [[jet fuel]] involved.
