Which guideline must be followed regarding lifeguard supervision during classes?

Maintaining dedicated lifeguard supervision during classes is essential for ensuring the safety of all participants. This guideline is in place to provide a responsible individual specifically trained to recognize and respond to emergencies in the water, which is critical in any aquatic environment.

Lifeguards have specialized training that equips them with the skills to monitor participants, recognize signs of distress, and execute emergency interventions if needed. Having dedicated lifeguard supervision ensures that there is constant vigilance focused on the safety of swimmers, which cannot be guaranteed if instructors or untrained participants take on this role.

The effectiveness of lifeguard supervision is heightened by having someone whose sole responsibility is to oversee safety, allowing instructors to focus on teaching and ensuring that participants get the most out of the class while still being watched by someone with the proper training and authority to act in emergencies.
