What is the first step in a first aid approach when you arrive at a scene?

The first step in a first aid approach when arriving at a scene is to ensure the scene is safe. This is crucial because responding to an emergency without assessing the safety of the environment can put both the rescuer and the victim at further risk of harm. Hazards such as traffic, fire, or unstable structures need to be identified to prevent additional injuries.

When the safety of the scene is established, the rescuer can then safely approach the victim and provide assistance. This step prioritizes safety and allows for effective intervention without compromising the rescuer's well-being. Following this, the rescuer can then check for responsiveness, call for help if necessary, and proceed with any required first aid measures such as checking for a pulse or beginning CPR, depending on the situation.
