"Resource typing is one of the five components of the National Incident Management System (NIMS). Resource typing is the categorization and description of response resources that are commonly exchanged in disasters through mutual-aid agreements. By using standardized typing and terminology for all incidents and events, smoother interoperability will exist for multiagency/ multijurisdiction incidents and events. The National Integration Center (NIC) has developed and published over 120 resource typing definitions. Resource typing definitions can give emergency responders the information they need to make sure they request and receive the appropriate resources during an emergency or disaster. Ordering resources that have been typed using these definitions makes the resource request and dispatch process more accurate and efficient."
