Which of the following is NOT a safety measure at a crime scene?

Using cell phones freely at a crime scene is not considered a safety measure. In fact, it can pose risks both to the integrity of the evidence and to the safety of those present. Cell phones can potentially introduce contamination to the scene, as information about the crime or evidence could be inadvertently shared or compromised. Additionally, distractions caused by cell phone use can lead to unsafe handling of evidence or the overlooking of hazards present at the crime scene.

On the other hand, avoiding eating or drinking helps prevent contamination of evidence, wearing gloves protects both the investigator and the evidence from contamination, and avoiding sharp objects is essential for personal safety when navigating a potentially hazardous scene. These practices are integral to maintaining a secure and sterile environment during an investigation, ensuring that the evidence remains intact and the safety of all personnel is prioritized.
