Which factor is identified as the highest risk for illness, injuries, and fatalities among firefighters?

• A. Motor vehicle accidents
• B. Structural collapses
• C. Cardiac arrest as a result of overexertion
• D. Rapid changes in fire development

Answer: (C)

The main idea is that the biggest risk to firefighters in terms of illness, injuries, and deaths is cardiac arrest triggered by overexertion. Firefighting demands intense physical effort in heat, smoke, and stress, which puts a severe strain on the heart. For many firefighters, especially those with underlying heart disease or risk factors, the surge in heart rate and blood pressure during or after strenuous work can precipitate a heart attack or sudden cardiac arrest. This pattern has been seen repeatedly in fire service data, making exertional cardiac events the leading cause of line-of-duty deaths. Structural collapses, motor vehicle accidents, and rapid changes in fire development are all serious hazards and do cause injuries and fatalities, but they do not occur as frequently as cardiac events do across the population of firefighters. Emphasizing cardiovascular fitness, medical screening, proper pacing, hydration, heat management, and early recognition of chest pain or abnormal fatigue can help reduce this top risk.
