Taking a look at the 93 on-duty firefighter fatalities in 2017 reveals similar trends from previous years, with cardiac and health-related issues marking a bulk of the fire service's losses. According to numbers provided by the U.S. Fire Administration, the overwhelming physical stress firefighting has on the body remains at the forefront of modern firefighter health and safety. There were 58 line-of-duty deaths last year related to cardiac or other medical issues while firefighters were either on scene at an incident or within the 24-hour span afterward. Given these incidents, many firefighter organizations across the country continue to stress to need for proper diet and exercise to counter the demanding physical nature of the job.
