What steps should a First Responder take when arriving at an emergency scene?

The correct choice emphasizes the foundational protocol that first responders must follow when arriving at an emergency scene. The focus on assessing scene safety is paramount because it ensures the responder's safety and that of any bystanders before any further action is taken. A safe scene allows for effective intervention without risking additional injuries.

Calling for help immediately is crucial as it ensures that more resources are on the way, which is vital in emergencies where multiple victims may require assistance or when specialized medical care is needed. The primary assessment is a systematic approach to identify life-threatening conditions, enabling responders to prioritize care based on the severity of injuries.

This sequential approach aligns with established emergency response protocols, which empower first responders to act confidently and effectively in high-pressure situations. It also sets the foundation for further medical interventions and interactions with other emergency services.
