Effective actions during Phase 1 may mean the difference between a successfully managed incident and one in which effective incident management is achieved slowly or not at all. Phase 1 focuses on initial actions that must take place prior to the first operational period.
While many important tasks must be accomplished during this initial period, efforts focus on gaining an understanding of the situation and establishing initial incident priorities. Gaining an understanding of the situation includes gathering, recording, analyzing, and displaying information regarding the magnitude, complexity, and potential impact of the incident. This is essential to develop and implement an effective IAP.
This is also when the initial IMAT meeting is conducted to ensure that incident management personnel understand Unified Coordination Group (UCG) expectations for the incident and initial strategies, and plans for integrating other UCG members into the IMAT.
Establishing initial incident priorities is generally done by high level authorities such as the Governor of the affected State and the FEMA Regional Administrator (RA).
