The correct choice emphasizes the critical importance of maintaining the integrity of evidence at an incident scene. Security personnel must avoid altering or contaminating any evidence, as this can compromise the investigation and the potential for legal proceedings. By not touching or sizing evidence, security personnel help ensure that anything that could be crucial for understanding what happened remains as it is, preserving its original state for law enforcement investigation. This is a fundamental principle in evidence handling, as any modifications or mishandling could lead to questions about the validity of the evidence in a courtroom.

In contrast, the other actions described could negatively impact the scene and any subsequent investigation. For example, asking for public help to look for evidence could introduce individuals who may unintentionally disturb the scene further. Walking through the area might inadvertently interfere with evidence, and collecting evidence before police arrive risks losing valuable information and proper chain-of-custody procedures. Each of these actions could diminish the effectiveness of the investigation and reduce the chances of resolving the incident conclusively.
