What can result from ‘Extreme cold’ as defined in the thermal hazards?

• A. Hypoxia due to oxygen displacement
• B. Frostbite or hypothermia
• C. Long-term emotional distress
• D. Cancer due to radiation exposure

Answer: (B)

Extreme cold is characterized by conditions where the air temperature drops significantly, leading to the risk of serious bodily harm. Frostbite occurs when skin and underlying tissues freeze, often affecting extremities like fingers and toes, while hypothermia happens when the body loses heat faster than it can produce it, resulting in a dangerously low body temperature. These conditions arise directly from exposure to extreme cold and can be life-threatening if not addressed promptly. Understanding the physiological impacts of extreme cold is crucial in hazardous materials situations where individuals may be exposed to such conditions, making it an important topic for safety training and awareness in emergency response contexts.
