What is one of the responsibilities of a lifeguard during an emergency?

Providing clear instructions and assistance is a fundamental responsibility of a lifeguard during an emergency. In critical situations, effective communication can save lives and ensure the safety of all individuals involved. Lifeguards are trained to assess emergencies quickly and convey necessary actions to swimmers, such as moving to safety or following evacuation procedures. This clarity helps reduce panic and confusion, allowing for a more organized and effective response to the emergency.

The other choices, while they may have some relevance in certain contexts, do not align with the immediate responsibilities of a lifeguard during an emergency. Documenting incidents is important for future training but is not a primary action during a live situation. Retreating and waiting for authorities could compromise the safety of swimmers who may need immediate assistance. Finally, gathering swimmers for a fun activity is inappropriate and could be dangerous if there is an ongoing emergency that requires attention and resolution first.
