At the national level, FEMA leads the development and maintenance of NIMS resource typing definitions that are national in scope.

States should inventory their assets to determine if national resource types are in the State. If they are, the State should maintain an inventory of these national resource types for use in the event of an incident. States that do not have any national resource types in their inventories are not required to purchase them.

Urban Search and Rescue Task Forces are an example of a resource that is national in scope and should be inventoried.

These NIMS resource typing definitions can serve as a useful guide for States when developing their own definitions for resource types that are not included in the NIMS resource typing definitions.
