What does the acronym PLS stand for in rescue operations?

In rescue operations, the acronym PLS stands for "Point Last Seen." This term refers to the last known location of an individual before they went missing or encountered difficulties, especially in environments like swiftwater or wilderness settings. The significance of identifying the Point Last Seen is crucial for search and rescue teams as it helps establish a primary base from which search efforts should be initiated. The farther the search moves from this point, the higher the level of uncertainty and difficulty in locating the subject increases.

Understanding the context of PLS aids responders in planning and executing an effective search strategy, including determining search patterns and resource allocation. While the other phrasing options might seem valid, they do not align with the accepted terminology used by rescue professionals. "Point Last Seen" encapsulates the essence of the phrase in a concise manner, making it the standard term in rescue operations.
