During a rescue, the first action upon encountering an unresponsive guest should always be to?

The first action upon encountering an unresponsive guest should indeed be to ensure the scene is safe. This is crucial because approaching an unresponsive individual without ensuring the environment is safe can pose significant risks to both the rescuer and the victim. Hazards in the environment, such as strong currents, nearby moving objects, or other dangers, must be assessed before attempting a rescue. If the rescuer does not prioritize safety, they might become a second victim rather than an effective responder.

Once safety is confirmed, the rescuer can proceed with other vital actions such as assessing the victim's responsiveness and checking for breathing. This sequence helps to prevent further harm and ensures that the rescue can be performed effectively. If the scene is determined to be unsafe, the rescuer should take appropriate measures, such as calling for emergency services or using equipment to assist with the rescue, all of which hinge on prioritizing safety first.
