"Scene preservation" in a security environment refers to the importance of maintaining the integrity of a crime scene to ensure that evidence remains uncontaminated and available for investigation. This process is critical, as any alteration or disturbance at the scene can compromise evidence, making it difficult or impossible for law enforcement to accurately determine what occurred.

This concept emphasizes the need for security personnel to limit access to the area, avoid touching or moving objects, and be vigilant about permitting only authorized individuals to enter the scene. By preserving the scene as it exists immediately after an incident, investigators can collect reliable evidence, such as fingerprints, DNA, and other forensic materials, which are vital in solving the case.

The other options, although related to incident management, do not accurately define scene preservation. Documenting events is important, but it does not relate directly to the physical integrity of the scene. Removing individuals from the scene might be necessary, but it's not the essence of preservation. Changing the positioning of items would inherently disrupt the scene, which contradicts the goal of preserving it for accurate evidence collection.
