Which survey technique is used to locate the general boundaries of a CBRN contaminated area?

• A. Bounce-and-Bypass
• B. Lane Locate Technique
• C. Grid Search
• D. Area Sweep

Answer: (B)

Locating general boundaries quickly requires a method that yields fast, broad delineation with limited exposure. The Lane Locate Technique accomplishes this by moving through the area in defined parallel lanes and using detectors to mark where contamination begins at the lane edges. As readings are collected, the boundary is sketched on a map, providing a workable perimeter for immediate actions and planning. This approach is preferred when you need a quick perimeter because it focuses on finding the outer limits, not every detail of contamination. In contrast, a full grid search or area sweep aims to locate all contamination and map its extent in greater detail, which takes more time. Bounce-and-bypass involves movement around obstacles and doesn’t establish contamination boundaries.
