If a lifeguard cannot quickly locate a submerged victim, what should be their next step?

The best course of action when a lifeguard cannot quickly locate a submerged victim is for at least two guards to begin a search of the area where the victim was last seen. This answer is correct because a coordinated and immediate response maximizes the chances of locating and rescuing the victim quickly. When multiple lifeguards search together, they can cover more ground effectively and support each other in the search process. Additionally, having more than one lifeguard involved means that one can focus on searching while the other can maintain communication with emergency personnel or keep an eye on the surface for any signs of the victim, if necessary.

Acting swiftly and collaboratively is crucial in emergency situations, especially in a drowning scenario, where every second counts. The involvement of at least two lifeguards also ensures that the search remains organized, which is vital in managing the situation effectively and ensuring the safety of others in the area.

While waiting for a supervisor could potentially delay the response, sounding an alarm and evacuating the pool area without searching first might unnecessarily alarm the patrons and take time away from the critical search. Having only one lifeguard continuing the search is less effective, as the search could benefit greatly from multiple perspectives and additional resources.
