Which statement correctly describes the inner perimeter at a hostage barricade?

• A. An outer buffer protecting the public
• B. A zone where investigators set up command post
• C. A sterile zone-cleared of all civilians and non-essential personnel
• D. A secure area where media can operate

Answer: (C)

The inner perimeter is a controlled, sterile area immediately around the incident where only essential personnel are allowed. It’s cleared of civilians and non-essential staff to protect responders, prevent contamination of evidence, and reduce risk. This is distinct from the outer perimeter, which is the broader buffer protecting the public; the command post is typically set up at the edge to coordinate operations; and media operations occur outside, not inside, the inner perimeter. So describing the inner perimeter as a sterile zone cleared of civilians and non-essential personnel best fits the concept.
