How often should instructors check the pool for safety hazards during lessons?

Instructors should check the pool for safety hazards before each lesson and continuously during lessons to ensure a safe environment for all participants. This proactive approach allows instructors to identify and address any potential risks immediately, thus preventing accidents and ensuring that safety protocols are followed throughout the entire duration of the lesson. Continuous monitoring enables instructors to adapt to changes, such as weather conditions or the behavior of swimmers, which could introduce new hazards. By being vigilant and responsive, instructors can maintain a safe and secure swimming experience for everyone involved.
