What are the most common causes of death in the fire service?

• A. Electrocution and burns
• B. Trauma from vehicle accidents
• C. Cardiac arrests and suicide
• D. Smoke inhalation

Answer: (C)

The main idea here is recognizing what causes the most firefighter fatalities. The most common deaths come from sudden cardiac events and from suicide. Firefighting places extraordinary stress on the heart—extreme exertion, heat, dehydration, and sometimes underlying health issues—so heart-related deaths are the leading cause. Suicide is a major contributor as well because of the high stress, trauma exposure, and mental health challenges that can accompany the job; in recent years it has become a prominent cause of death in the fire service.

Other hazards, like electrocution and burns, fatalities from on-scene trauma (including vehicle crashes), or deaths from smoke inhalation, happen, but they do not occur as frequently as the combination of cardiac events and suicide. This is why cardiac arrests and suicide are the best answer.
