What is the leading cause of firefighter fatalities on duty?

• A. Smoke inhalation
• B. Cardiac arrest
• C. Drowning
• D. Burns

Answer: (B)

Firefighting places extreme stress on the heart. When responders move quickly in heavy personal protective gear, deal with heat, smoke, and dangerous environments, the cardiovascular system is asked to deliver a lot of blood to working muscles for extended periods. If a firefighter has underlying heart disease, is poorly conditioned, or becomes dehydrated or overheated, that demanding exertion can trigger a fatal cardiac event, such as cardiac arrest. For this reason, sudden cardiac events are the most common on-duty fatalities among firefighters, more so than injuries from smoke inhalation, drowning, or burns. The emphasis on fitness, medical screening, proper hydration, and controlled exertion helps reduce this risk.
