What is the leading cause of firefighter fatalities according to the cited data?

• A. Internal trauma
• B. Sudden cardiac arrest
• C. Thermal burns
• D. Falls

Answer: (B)

Sudden cardiac arrest is the leading cause of firefighter fatalities because firefighting places extreme demands on the heart. Heavy PPE and equipment, extreme heat and dehydration, and high physical exertion push the cardiovascular system to its limits. If a firefighter has underlying heart disease or risk factors, this combination can trigger a fatal heart rhythm disturbance or heart attack during or just after strenuous work. The cited data consistently show cardiac events account for more deaths than traumatic causes like falls, burns, or vehicle incidents, even though those hazards are real. This is why fitness, medical screening, and recognizing early signs of overexertion or chest pain are so important for safety.
