NRF elements can be implemented at any time for any hazard, including the employment of Emergency Support Function (ESF) mechanisms.

The structures, roles, and responsibilities described herein can be partially or fully implemented in the context of a threat or hazard, in anticipation of a significant event, or in response to an incident.

Implementation of NRF structures and procedures allows for a scaled response, delivery of the specific resources and capabilities, and a level of coordination appropriate to each incident.
