In sample mounted CBRN reconnaissance and surveillance procedures, which STEP is listed?

• A. Establish Perimeter
• B. Evacuate
• C. Decontaminate
• D. Clear Area

Answer: (D)

The action being tested is the crew’s priority to ensure the working space is safe before proceeding with reconnaissance. In mounted CBRN reconnaissance and surveillance, clearing the area means actively verifying that the immediate environment around the vehicle and along the planned route is free of hazards and contamination so you can operate without exposing personnel or spreading contaminants. The sample procedure explicitly lists this step, reflecting the need to establish a safe, controllable area as a prerequisite for subsequent actions like observation, reporting, or decontamination if needed. While other steps such as establishing a perimeter or triggering decontamination are common in CBRN operations, the given sample emphasizes clearing the area as the stated step to confirm safety before moving forward.
