Which of the following is NOT a signal to help recognize an emergency?

Recognizing signals of an emergency is crucial for a lifeguard to respond appropriately. Unusual sights, odors, and noises are all indicators that something may be wrong. These can include things like someone in distress, unexpected behavior, or even equipment failure, which necessitates immediate attention.

In contrast, regular behaviors do not suggest an emergency. They represent what is considered typical or expected activity in a given environment, such as a calm swimmer or children playing safely. In a lifeguard context, understanding these norms helps to identify deviations that may signify an emergency situation. Recognizing regular behaviors is important, as it provides a baseline that can help lifeguards spot when something is off and may warrant further investigation or action.
