What is the Cold Exposure Survival Model (CESM) used for?

• A. A model used in cases involving PIW and where persons are at risk of hypothermia when not immersed
• B. A model used for predicting avalanche risk
• C. A model used for assessing heat stroke
• D. A model used to estimate fuel consumption

Answer: (A)

The Cold Exposure Survival Model is used to estimate how long a person can survive in cold conditions and how quickly hypothermia might develop, especially in situations where there is potential immersion in water. It combines environmental factors like water and air temperature, wind, and clothing insulation with personal factors such as body size, metabolic rate, and activity level to produce an estimate of time to hypothermia and overall survival probability. This helps guide rescue planning, priorities, and protective decisions in cold-water or cold-air exposure scenarios. It’s specifically focused on cold exposure and hypothermia risk, not on avalanche risk, heat-related illnesses, or fuel consumption.
