National Mutual Aid System

IAFC's National Mutual Aid System – Request. Locate. Deploy.

The National Mutual Aid System (NMAS) will take mutual aid to the next level, creating a system where all users can access cutting-edge technology to request, geospatially locate and strategically deploy response resources.

NMAS is the evolution of the Intrastate Mutual Aid System (IMAS, 2006-2011) and Mutual Aid Net (2012 to date). It leverages the technical innovation and expertise of WebEOC and Esri, combined with the practical experience of the IAFC and our state and local partners and subject matter experts.

NMAS will provide:
