Urban search and rescue (US&R or USAR), also referred to as Heavy Urban Search and Rescue (HUSAR), is the location and rescue of persons from collapsed buildings or other urban and industrial entrapments. Due to the specialised nature of the work, most teams are multi-disciplinary and include personnel from police, fire and emergency medical services. Unlike traditional ground search and rescue workers, most US&R responders also have basic training in structural collapse and the dangers associated with live electrical wires, broken natural gas lines and other hazards. While [[earthquake]]s have traditionally been the cause of US&R operations, [[Terrorism|terrorist attacks]] and extreme weather such as [[tornado]]es and [[hurricane]]s have also resulted in the deployment of these resources.<ref name="FEMAAboutUSR">{{cite web|url = http://www.fema.gov/emergency/usr/about.shtm|title = About US&R|access-date = 11 January 2010|last = U.S. Department of Homeland Security|date=May 2009}}</ref>
