Final answer:
The personnel designated to support the Incident Commander by handling public information, safety, and liaison services in incident response management are known as the Command Staff.
Step-by-step explanation:
Within the structure of incident response management, the personnel designated to provide information, safety, and liaison services are collectively known as the Command Staff. This group plays a crucial role in supporting the Incident Commander by handling tasks such as public information dissemination, maintaining safety protocols, and coordinating among various authorities and organizations involved in the incident. These roles include the Public Information Officer, responsible for communications with the media and public; the Safety Officer, who ensures the safety of all incident response operations; and the Liaison Officer, who provides a point of contact for agency representatives and assists in the coordination of efforts. Particularly in large or complex incidents, the efficiency and effectiveness of the Command Staff are vital for a well-managed response.
