What action should a lifeguard take if they witness a swimmer struggling in the water?

When a lifeguard witnesses a swimmer struggling in the water, the appropriate action is to call for help. This ensures that additional trained personnel can respond, which is crucial in emergencies. Alerting others not only allows for a coordinated rescue effort but also helps ensure that the lifeguard's own safety is prioritized.

In many cases, the situation may appear urgent, but jumping in without proper assessment can lead to complications, such as a lifeguard becoming overwhelmed or unintentionally making the situation worse. Using a flotation device is also essential as it allows the lifeguard to assist the struggling swimmer more effectively and safely. Calling for help sets the stage for a more deliberate and safer rescue operation.
