Which survey technique is used to determine the general dimensions (length and width) of a contaminated area?

• A. Box
• B. Grid
• C. Bounce and Bypass
• D. Trace and Mark

Answer: (A)

To quickly gauge the general size of a contaminated area, you want a simple boundary that contains everything you need to plan the next steps. The Box method does this by creating a rectangular boundary around the area: you locate the outer edges, extend straight lines to form corners, and complete a rectangle that encloses the contamination. Measuring the length and width of that rectangle gives you the rough dimensions you need for initial actions, without the time it takes to map every detail. This approach is faster and sufficient when the goal is a broad estimate of extent. A Grid method, while more precise, requires more time and setup to map contamination point by point. Trace and Mark helps you document boundaries as you go but doesn’t by itself provide a quick, bounding measurement. Bounce and Bypass is about maneuvering around obstacles rather than establishing the footprint.
