How do firefighters from one state end up on a fire in another state?
If a wildfire grows to an extent that local firefighting personnel and equipment can’t handle it alone, fire managers can request more equipment, personnel and logistical support through a local dispatch center. If necessary these requests are sent to a Geographic Area Coordination Center (GACC) and even to the National Interagency Coordination Center (NICC) in an attempt to locate and send available resources. In some cases, wildland firefighters are even shared between the United States and Canada, Australia, and New Zealand..
