Which action listed after an attack involves removing or restricting access to contaminated areas to protect people?

• A. Clearance
• B. Search and Rescue
• C. Decommissioning
• D. Public messaging

Answer: (A)

The action focuses on preventing exposure by keeping people out of or limiting access to areas that may be contaminated. This is clearance: establishing exclusion zones, posting entry restrictions, and controlling who can enter based on safety precautions and contamination levels. By physically restricting access, you protect both responders and the public while you assess and address the hazards inside. Other options don’t fit as well. Search and Rescue is about finding and helping people in danger, not about restricting access. Decommissioning means taking equipment or systems out of service, not specifically about protecting people from contamination in an area. Public messaging informs people about risks but doesn’t by itself restrict access to the contaminated space.
