Unified Command (UC)
The Unified Command (UC) is an Incident Command System (ICS) structure used when multiple agencies, jurisdictions, or organizations share responsibility for managing an incident. This situation often occurs during large or complex emergencies such as hazardous materials releases, natural disasters, transportation accidents, or incidents that affect multiple jurisdictions or regulatory authorities. In these situations, no single agency has complete authority, so representatives from the involved organizations work together within a unified management structure.
Under Unified Command, each participating agency designates an authorized representative to serve as part of the command structure. These representatives collaborate to establish common incident objectives, develop response strategies, and coordinate the use of available resources. Although several agencies share leadership, Unified Command ensures that the incident is managed through a single, coordinated action plan rather than separate or conflicting efforts.
The Unified Command approach helps improve communication, coordination, and efficiency during emergency response operations. It allows agencies with different legal, geographic, or functional responsibilities—such as fire departments, law enforcement, environmental agencies, and public health organizations—to work together effectively while still maintaining their individual authorities and responsibilities.
Command Staff
The Command Staff is responsible for public affairs, health and safety, and liaison activities within the Incident Command System (ICS).
The IC/UC remains responsible for these activities or may assign individuals to carry out these responsibilities and report directly to the IC/UC.
- The Information Officer develops and releases information about the incident to the news media, incident personnel, and other appropriate agencies and organizations.
- The Liaison Officer serves as the point of contact for assisting and coordinating activities between the IC/UC and various agencies and groups. Persons contacted may include Congressional personnel, local government officials, and criminal investigating organizations and investigators arriving on the scene.
- The safety officer is knowledgeable in the operations implemented at the emergency response site. Safety officer specific responsibilities are to:
- identify and evaluate hazards, and
- provide direction concerning the safety of operations for the emergency at hand.
When activities are judged by the safety officer to be an IDLH and/or to involve an imminent danger condition, the safety officer shall have the authority to alter, suspend, or terminate those activities. The safety official shall immediately inform the individual in charge of the ICS of any actions needed to be taken to correct these hazards at the emergency scene.
