Which roles are typically considered part of the command staff that collaborate with the Incident Commander on the IAP?

• A. Public Information Officer
• B. Safety Officer
• C. Liaison Officer
• D. All of the above

Answer: (D)

The command staff work with the Incident Commander to handle cross-cutting functions that affect how the incident is communicated, how safety is maintained, and how coordination with other agencies happens, all of which shape the IAP. The Public Information Officer is responsible for official communications to the public and the media, making sure information about the incident and the IAP is accurate and timely. The Safety Officer focuses on hazards and safety procedures, advising the IC on risks and any changes needed in the plan to keep responders and the public safe. The Liaison Officer acts as the primary point of contact with other agencies and jurisdictions, smoothing interagency coordination and ensuring external resources and considerations are integrated into the IAP. Because each of these roles directly supports the IC in developing and adjusting the IAP through information sharing, safety oversight, and interagency collaboration, all of them belong to the command staff.
