True or False: Guests can be at risk without being visibly distressed.

The statement that guests can be at risk without being visibly distressed is true. Lifeguards are trained to recognize that a person's potential need for assistance may not always be apparent through physical signs of distress. Various factors can lead to a swimmer in trouble that may not manifest in visible ways, such as panic, fatigue, or medical conditions.

Environmental conditions, such as strong currents or water temperatures, can affect a guest's ability to swim safely without showing obvious signs of distress. Additionally, individuals may hesitate to call for help or may not show distress until it is too late. Thus, a vigilant lifeguard must maintain awareness of all guests and the surrounding environment to detect any potential hazards or risks, regardless of whether they are visible. Recognizing that danger can exist even in the absence of overt signs of distress is crucial for effective lifeguarding and ensuring the safety of all guests in the pool or aquatic facility.
