Which of the following is NOT a required logbook entry for lifeguards?

A lifeguard's logbook serves as an important tool for documenting essential information regarding the safety and operation of the aquatic facility. Required logbook entries typically include weather conditions, staff attendance, and water quality measurements, as these elements are crucial for ensuring that the environment remains safe for patrons.

Weather conditions need to be recorded because they can affect the safety and operational decisions made by lifeguards, particularly during activities like swimming or opening and closing the facility. Staff attendance is equally important for ensuring adequate supervision and accountability, making it easy to track who is on duty at all times. Water quality measurements are vital for maintaining health standards and ensuring that the pool water is safe for swimmers.

In contrast, personal notes are not categorized as a required logbook entry. While lifeguards may choose to include personal observations or notes for their reference, these do not pertain to the operational safety and health standards that require formal documentation. This distinction highlights the difference between critical, regulated data that must be logged for compliance and operational purposes versus subjective entries that might be useful on an individual basis but are not mandated.
