Which of the following is NOT a method for recognizing guests in distress?

Recognizing guests in distress is critical for lifeguards to ensure safety at swimming facilities. Among the methods for identifying such situations, proactive scanning, facial expressions, and breathing efforts are all effective strategies.

Proactive scanning involves actively monitoring the pool area and paying close attention to guests' behavior and activities, which can help identify those who may need assistance. Facial expressions can show signs of distress, fear, or discomfort, allowing lifeguards to intervene when necessary. Observing breathing efforts can also provide valuable information; for example, if a guest is struggling to breathe or appears to be gasping, this is a clear sign of distress.

In contrast, ignoring unusual behavior is not a method for recognizing distress; rather, it represents a lack of vigilance and can lead to dangerous situations where help is not provided in a timely manner. Therefore, this response correctly identifies the approach that does not align with the responsibilities of a lifeguard in recognizing guests who may be in trouble.
