Which statement about litter harnesses is correct?

The statement that each type of litter harness serves a specific purpose based on positioning is accurate because various harness designs are crafted to meet distinct operational needs during rescue scenarios. For example, some harnesses are shaped for vertical hauling, while others may be optimized for horizontal transport or to secure patients in different positions. This specialization ensures that the harness not only supports the weight of a patient effectively but also aligns with the positioning required for safe extraction or transport, adapting to various terrains and situations encountered during rescues. This targeted functionality is crucial in ensuring the safety and efficiency of both the patient and the rescuers involved.
