Which term describes the process of safely lowering a subject in a rescue operation?

The term that describes the process of safely lowering a subject in a rescue operation is "descent." This term specifically refers to the controlled movement of a person downward, typically using ropes, harnesses, and other technical equipment designed to ensure safety during the lowering process.

In rescue operations, managing the descent effectively is crucial to minimize risks to both the subject being rescued and the rescuers involved. It incorporates various techniques and safety measures to prevent accidents, ensuring the subject is lowered steadily and without undue stress or danger.

The other terms, while related to different aspects of rescue operations, do not specifically capture the act of lowering a subject. "Evacuation" refers to the process of removing individuals from a dangerous situation, "extraction" pertains to the act of removing a person from a hazardous environment, and "transportation" involves moving a person from one location to another after they have been evacuated. Each of these terms plays a role in the broader context of rescue operations, but "descent" precisely defines the controlled lowering process.
