What is one of the additional responsibilities of a lifeguard?

The documentation of every rescue is a vital responsibility for a lifeguard. This task ensures that detailed records are kept for accountability and analysis of incidents. Documenting rescues helps in reviewing what went well and what could be improved, contributing to ongoing training and safety measures. Additionally, this information can be crucial for legal purposes, providing a clear history of incidents that occur while on duty.

In contrast, while managing the snack bar, conducting swimming lessons, and cleaning the pool area may involve a lifeguard's skills or functions, they are not primary responsibilities directly associated with the core duties of a lifeguard focused on safety and rescue operations. These tasks can often be handled by other staff or be seen as additional duties rather than essential components of lifeguard responsibilities.
