When should a lifeguard call for additional help during an emergency?

A lifeguard should call for additional help as a preventive measure before initiating any rescue because this ensures that assistance is on the way while the lifeguard is immediately addressing the situation. In emergencies, time is of the essence, and having additional resources available can be crucial to the safety and effectiveness of the rescue operation.

By calling for help before starting the rescue, the lifeguard can focus on the individual in distress without the distraction of potentially needing to do so later in a more urgent scenario. This proactive approach helps to create a safer environment not only for the victim but also for the lifeguard and any other individuals involved in the situation.

In contrast, waiting for the situation to escalate, providing aid first, or completing a rescue before seeking help may lead to delays that can exacerbate the emergency and increase the risk to all parties involved.
