According to the National Incident Management System (NIMS), and the Incident Command System (ICS), the Incident Command Post (ICP) is one of five predesignated temporary facilities and signifies the physical location of the tactical-level, on-scene incident command and management organization. It typically comprises the Incident Commander and immediate staff and may include other designated incident management officials and responders from Federal, State, local, and tribal agencies, as well as private-sector, nongovernmental, and volunteer organizations.
