What describes a passive search in water rescue scenarios?

In water rescue scenarios, a passive search refers to a situation where rescuers initiate a search without having definitive information about where the victim was last seen. This approach is typically employed when there is uncertainty regarding the last known location of the individual, making it imperative to cover a broader area rather than following precise leads. The passive search strategy generally involves a more methodical and observational stance, as rescuers may look for signs of the victim’s presence, such as personal effects or patterns in the water, rather than acting on immediate, specific witness accounts or leads.

This differs from other search strategies where clear, specific information from witnesses can direct the effort more effectively towards where the victim might be found. Therefore, the focus of a passive search is on collection and assessment of information rather than direct engagement or rapid action based on strong leads.
