When should a lifeguard call for emergency services?

A lifeguard should call for emergency services when the situation exceeds their training because this ensures that victims receive the appropriate level of care that the lifeguard is not equipped to provide. Lifeguards are trained to handle a range of emergencies, but there may be incidents involving severe injury or medical conditions that require specialized medical assistance. By recognizing the limits of their training and involving emergency services, lifeguards act in the best interest of the victim's health and safety.

Calling for help when the situation exceeds one's training is also aligned with the emergency response protocols and helps ensure that the rescue and care are handled effectively. Timely alerts to emergency services can drastically improve outcomes, especially in critical situations where every moment counts.

The other options focus on personal feelings, routine processes, or authority directives, which do not adequately address the immediate need for professional medical assistance.
