What is the first step in the BLS sequence?

The first step in the BLS sequence involves ensuring that the scene is safe. This step is crucial because it assesses the environment for any potential hazards that could pose a risk to the rescuer or the victim. By confirming the safety of the scene before proceeding, the rescuer can avoid putting themselves in danger, which would hinder their ability to assist the victim effectively.

Once the scene is deemed safe, the rescuer can then move on to checking for responsiveness, calling for help if necessary, and initiating high-quality chest compressions if the victim is unresponsive and not breathing normally. Safety is the foundation of effective emergency response, allowing for timely and appropriate care to be provided.
