National Interagency Fire Center (United States)

Last Updated: June 13, 2022, 7:47 pm

The National Interagency Fire Center (NIFC) in Boise, Idaho is the physical facility which is the home to the National Interagency Coordination Center (NICC), and the National Multi-Agency Coordination group (NMAC or MAC). NIFC is responsible primarily for the interagency co-ordination of wildland firefighting resources in the United States, but also for other emergencies such as floods, hurricanes, and earthquakes.

NIFC maintains the National Incident Radio Support Cache (NIRSC) to support these incidents. Communications assets and frequency usage are assigned as needed on an incident-by-incident basis.

These assets are generally known and can be heard referred to on the air as the "NIFC System."

Frequencies found in the National Interoperability Field Operations Guide (NIFOG) may also be used at these incidents.
