What is a sign for a lifeguard to be alert regarding swimmer safety?

A sign for a lifeguard to be alert regarding swimmer safety is the presence of struggling swimmers. This indicates that an individual may be in distress, which requires immediate attention from lifeguards. Recognizing signs of struggle, such as a swimmer who is unable to keep their head above water, indicates that they may require assistance, signaling the lifeguard to intervene promptly to prevent potential drowning or injury.

The inability to swim effectively or remaining in the water without safety can escalate quickly if not addressed. Lifeguards are trained to identify such situations quickly and act decisively to safeguard those in the water. Maintaining vigilance for struggling swimmers is crucial because timely intervention can make a significant difference in emergency situations.

While laughter, chatting, and jumping off slides may not immediately indicate danger, they do not demonstrate signs of distress or risk that would alert a lifeguard to take immediate action regarding swimmer safety.
