What is the main cause of firefighter fatalities in structural fires?

Cardiac events are indeed the leading cause of firefighter fatalities in structural fires. This is primarily due to the intense physical demands and stress that firefighting imposes on the body. Firefighters often face extreme heat, heavy gear, and the need for rapid response during emergencies, all of which can place significant strain on the cardiovascular system.

Additionally, the adrenaline rush associated with firefighting can lead to heightened heart rates and increased blood pressure, making individuals more susceptible to heart attacks, especially if they have underlying health issues.

While other factors, such as smoke inhalation, building collapse, and burn injuries, can also pose serious risks and contribute to firefighter fatalities, research consistently shows that cardiac events account for a larger percentage of firefighter deaths in structural fire situations. This underscores the importance of fitness, health monitoring, and proper stress management for firefighters in the line of duty.
