The appropriate answer is that emergency back-up coverage protocols take effect when a lifeguard enters the water for a rescue. This is important because the lifeguard's primary responsibility is to ensure the safety of the patrons, and when they commit to a rescue, their ability to monitor the entire facility is compromised. Therefore, activating back-up coverage at this moment is crucial for maintaining safety and ensuring that the area remains supervised while resources are focused on the rescue effort. This ensures that other patrons continue to receive oversight and assistance as needed during an urgent situation.

While other scenarios, such as lifeguard absences or exceeding capacity, are important considerations for overall safety management, they do not specifically trigger emergency back-up coverage protocols like entering the water for a rescue does. Activating the emergency action plan might involve various procedures but does not specifically relate to back-up coverage for a lifeguard currently engaged in a rescue.
