What must be the first consideration before providing treatment during an emergency call?

The primary consideration before providing treatment during an emergency call is ensuring the scene is safe. This is crucial for both the safety of the patient and the healthcare provider. If the scene is not secure, there may be potential hazards such as traffic, fire, or violent individuals that could pose a risk to everyone involved.

By ensuring the scene is safe, emergency medical personnel can focus on delivering effective care without the risk of personal injury or exacerbating the situation. A safe environment allows for a proper assessment and treatment of the patient, making it a foundational step in emergency response protocols. Without this initial assurance of safety, any subsequent actions, such as assessing vital signs or determining medical history, could endanger both the responder and the patient.
