What should you do if no victim is spotted in moving water?

When no victim is spotted in moving water, interviewing witnesses to determine the Point Last Seen (PLS) and the time lapsed is essential for several reasons. Understanding the PLS helps rescuers to narrow down the search area and focus their efforts effectively. Knowing where the victim was last seen allows for a more targeted approach rather than randomly searching the entire river, which can be inefficient and potentially dangerous given the dynamics of moving water.

Additionally, gathering information about the time lapsed since the victim was last seen can greatly influence search strategies. In rescue operations, time is a critical factor, and every minute counts when dealing with potential drowning scenarios. This information allows responders to assess the urgency of the situation and organize their response accordingly. By combining both the point and timeframe, rescuers can create a more strategic and effective plan, improving the chances of locating the victim within a critical timeframe.

Other options present less effective strategies in this scenario. Searching the entire river may waste valuable time and resources without concrete information to direct the search. Waiting for more information could cause delays that may jeopardize the victim's chances of survival. Leaving the area would be counterproductive, as it would remove responders from a location where they can gather vital information and coordinate an effective response.
