What should a lifeguard do before entering the water to perform a rescue?

Before entering the water to perform a rescue, a lifeguard's primary action should be to assess the scene for safety and potential hazards. This step is crucial because it ensures the lifeguard’s own safety before attempting to assist someone in distress. By evaluating the environment for dangers such as rough waves, strong currents, the presence of debris, or overcrowded areas, the lifeguard can make an informed decision on whether it is safe to proceed with the rescue.

Assessing the scene not only protects the lifeguard but also ensures the safety of the victim and any bystanders. It allows the lifeguard to identify the best approach for the rescue, including contingency plans should conditions change or if additional help is needed. Ultimately, prioritizing the assessment of the scene helps maintain a safer environment for everyone involved during a critical time.
