A way to establish perimeters is to ensure that initial perimeters are larger than necessary for investigators.

• A. outer boundaries
• B. initial perimeters
• C. secondary zones
• D. inner limits

Answer: (B)

When addressing a scene, you establish boundaries to control access, protect people, and preserve evidence. The key idea being tested is that the first boundary set around the scene is intentionally larger than what you might ultimately need. This initial perimeter provides a safety margin and gives investigators room to work while they assess conditions. The term that fits this practice is initial perimeters—the first boundaries established at the scene, which are often oversized and can be narrowed later if needed. Outer boundaries might describe the edge, but it doesn’t specify that this is the initial, oversized boundary; secondary zones and inner limits refer to areas inside the main edge or separate zones, not the initial boundary itself.
