What is thermal layering and why is it important in rescue?

• A. Using clothing and blankets to maintain body temperature and prevent hypothermia during rescue
• B. A color-coding system for patient triage
• C. To organize equipment in layers
• D. A signal system based on temperature readings

Answer: (A)

Thermal layering is about keeping the body warm by using multiple clothing layers and blankets to trap air and minimize heat loss in cold or wet conditions during a rescue. It works by combining a moisture-wicking inner layer to move sweat away from the skin, a middle insulating layer to trap heat, and an outer shell to shield against wind and water. This setup helps prevent hypothermia, preserves cognitive function and physical ability, and makes it safer and easier to manage the rescue while waiting for extraction. Layers can be adjusted as conditions change, which is a key advantage. The other choices describe triage color coding, organizing gear, or signals based on temperature readings, but they don’t address keeping someone warm, which is the essence of thermal layering.
