What health issue remains the leading cause of firefighter fatalities?

• A. cancer
• B. obesity
• C. hearing loss
• D. cardiovascular disease

Answer: (D)

Cardiovascular disease, including sudden cardiac events, is the leading health issue behind firefighter fatalities. The job’s extreme physical and thermal stress—high heart rates during calls, heavy gear, heat, and strenuous activity—can trigger fatal cardiac events, especially in firefighters with risk factors like age, obesity, high blood pressure, or smoking. Because these cardiac events can occur during or after intense activity, they have historically accounted for more on-duty deaths than other health problems. Efforts to reduce fatalities emphasize cardiovascular fitness, regular medical evaluations and clearance, and managing risk factors. While cancer, obesity, and hearing loss are important concerns, cardiovascular events have consistently been the most common cause of fatal incidents.
