What is the term for the boundary that surrounds a death scene?

The term for the boundary that surrounds a death scene is referred to as the scene perimeter. This boundary is crucial in the field of death investigation as it marks the area that needs to be preserved and protected to prevent contamination of potential evidence. The scene perimeter is established by investigators to control access to the scene, ensuring that it remains undisturbed while a thorough examination and investigation are conducted. This allows for a systematic collection of evidence, which is essential for legal proceedings and the determination of the circumstances surrounding the death.

The other options do not specifically refer to this established boundary in the context of a death scene. While terms like "investigation margin" and "containment zone" may imply some form of boundaries within investigative contexts, they do not specifically denote the established perimeter that is standard in death scene management. "Safety barrier" also pertains more to access control for safety reasons than to the formal delineation of the investigative area. Thus, scene perimeter is the most accurate term to describe the boundary that surrounds a death scene.
