What is a 'sweep' in the context of search and rescue?

In the context of search and rescue, a 'sweep' refers to a systematic search of an area to locate missing persons. This procedure is crucial for effectively covering a designated area to ensure that no potential locations where individuals might be found are overlooked. The process typically involves organizing search teams that move through the area methodically, often using a grid pattern or predefined routes, which helps maximize the likelihood of locating anyone in distress. This technique emphasizes thoroughness and coordination among team members to enhance the success rate of recovery efforts. The use of a structured approach is essential in search and rescue operations to ensure all areas are checked systematically.

Other options, while they represent important concepts in firefighting and rescue operations, do not align with the definition of a 'sweep' in this specific context.
