Which of the following actions can increase the safety of swimmers?

Conducting regular safety drills is a key action that can significantly enhance the safety of swimmers. These drills enable lifeguards to practice and refine their emergency response skills in various scenarios. By simulating situations such as a swimmer in distress or a medical emergency, lifeguards become more prepared to react quickly and effectively when real incidents occur.

Additionally, safety drills foster teamwork among lifeguards, ensuring that everyone understands their roles during an emergency. This not only builds confidence but also helps to create a safer environment for swimmers, as lifeguards are more adept at managing risks and responding to potential hazards. Regular drills also serve as a reminder to all staff about the importance of vigilance and continuous improvement in safety practices.

Other options, while they might seem beneficial on the surface, do not directly improve swimmer safety in the same manner. Creating stricter rules might enforce discipline, but if lifeguards are unprepared, such rules may not prevent emergencies. Reducing surveillance and limiting the number of lifeguards on duty negatively impact the overall safety of swimmers, as fewer eyes on the pool can lead to undetected incidents and slower response times.
