Which of the following actions can help preserve scene safety?

Verifying the presence of emergency personnel is crucial for preserving scene safety because their training and presence can significantly enhance the safety of both the responders and the victims involved. When emergency personnel are present, they can help manage the scene, provide additional support, and ensure that proper protocols are followed for maintaining safety. This collaboration reduces the risk of secondary accidents and ensures that the response is coordinated and effective.

In contrast, ignoring the environment, proceeding without checking for hazards, and acting alone without a plan can all lead to unsafe situations. Neglecting to assess the surroundings may result in exposure to dangers, such as traffic or hazardous materials, whereas moving forward without a safety check could put responders at risk of injury. Acting alone without a plan can also lead to confusion and increased risks when dealing with emergencies.
