Outer perimeter location at technical rescue incidents is determined by?

• A. Incident Commander
• B. Safety Officer
• C. Public Information Officer
• D. Operations Chief

Answer: (A)

The person in charge at the scene (the Incident Commander) determines the outer perimeter. Establishing the incident perimeter is part of the overall command function: it defines where access is restricted, where hazards are contained, and how resources and safety controls will be organized to protect both the public and rescue personnel. The Safety Officer can raise safety concerns and suggest boundary adjustments, but the final decision rests with the person directing the operation to ensure a clear, unified plan. The Operations Chief carries out the tactical plan and may manage sectors and movement within that boundary, while the Public Information Officer handles communications. Boundaries can change as the situation evolves, but the authority to set the outer perimeter originates with the Incident Commander.
