The National Incident Management System (NIMS) provides a systematic, proactive approach to guide departments and agencies at all levels of government, nongovernmental organizations, and the private sector to work seamlessly to prevent, protect against, respond to, recover from, and mitigate the effects of incidents, regardless of cause, size, location, or complexity, in order to reduce the loss of life and property and harm to the environment. NIMS works hand in hand with the National Response Framework (NRF). NIMS provides the template for the management of incidents, while the NRF provides the structure and mechanisms for national-level policy for incident management. This document was developed through a collaborative intergovernmental partnership with significant input from the incident management functional disciplines, NGOs, and the private sector. Originally published on March 1, 2004, the document was revised in 2008 to reflect contributions from stakeholders and lessons learned during recent incidents.
