Technicians must undergo medical monitoring and operations, because working in full body protective clothing put them at higher risk of developing ____________, which is a potentially deadly condition.

• A. Hyperthermia
• B. Dehydration
• C. Heat stroke
• D. Cardiovascular collapse

Answer: (C)

When you wear full-body protective clothing, your body has a harder time getting rid of heat. The suit and equipment trap heat and moisture, so your core temperature can rise faster during work. In this context, the most dangerous outcome is heat stroke—the body's heat-regulation system fails, leading to a dangerously high core temperature and central nervous system dysfunction (such as confusion, seizures, or loss of consciousness). That combination is life-threatening and requires immediate cooling and medical care, which is why medical monitoring during operations in PPE is essential.

Dehydration is common but not the specific deadly condition described, and hyperthermia is a broad term that can lead to heat stroke but doesn’t specify the severe, immediate danger. Cardiovascular collapse can occur in extreme cases but is not the particular risk highlighted by this scenario.
