What should you do first when you arrive at the scene of an emergency?

Ensuring the scene is safe is the first priority when arriving at an emergency because it protects both the rescuer and the victim. If the scene is dangerous, such as in the presence of traffic, fire, or any other hazards, attempting to assist the victim without securing safety could result in additional injuries or complications, including the rescuer becoming a victim themselves.

Once safety is established, the responder can then evaluate the situation and proceed with appropriate actions, whether that's assessing the victim, calling for emergency assistance, or starting CPR if it's warranted. It is crucial to verify that the area is free of obstacles and risks before engaging in any response, as this fundamental step lays the foundation for effective emergency care.
