What should lifeguards do at the first sign of thunder or lightning?

At the first sign of thunder or lightning, lifeguards should take immediate action to ensure the safety of all patrons by clearing everyone from the water. Lightning poses a significant risk, as water is a good conductor of electricity, making individuals in or near it highly vulnerable during a storm. Lifeguards are trained to recognize that even the early signs of a storm warrant immediate attention to protect the health and safety of everyone present.

This proactive response prevents potential accidents and injuries that could occur if patrons were allowed to remain in the water. Clearing the water area allows lifeguards to focus on ensuring that everyone is safely out of the reach of lightning and other storm hazards, thereby affirming their responsibility to maintain a safe environment. After clearing patrons from the water, lifeguards should then follow facility protocols, which may include seeking shelter and monitoring the situation.
