What is the highest risk factor among firefighters for illness, injuries, and fatalities?

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

Answer: (C)

The key point is that heart-related events from heavy exertion are the greatest risk to firefighters. Firefighting is extremely demanding: workers don full protective gear, endure heat, carry heavy loads, and perform strenuous tasks in challenging environments. This combination places a huge demand on the heart, and if a firefighter has underlying cardiovascular disease or isn’t in good cardiovascular shape, exertion can trigger a heart attack or sudden cardiac arrest during or after a call. Over years of data, sudden cardiac death has been the leading cause of on-duty firefighter fatalities, outpacing fatalities from vehicle crashes, structural collapses, or rapid changes in fire conditions. So the most serious and frequent risk factor is cardiac events due to overexertion. Good fitness, medical screening, proper pacing on scenes, hydration, and recognizing warning signs like chest pain or dizziness are essential protections.
