The Madison Fire Department is examining its health programs and policies as federal officials plan to investigate the death of one of the department’s members earlier this year after a stressful shift. While it’s still unclear seven months later if a taxing 48-hour shift contributed to the sudden heart attack death of firefighter and paramedic Richard Garner, the fire department is looking at whether its wellness programs, fitness testing policies and shift scheduling could better prevent job-related health problems or deaths. The department’s self-examination also comes as the National Institute for Occupational Safety and Health (NIOSH), an arm of the Centers for Disease Control and Prevention, plans to probe Garner’s death to see if there could be a link between its circumstances and several other similar firefighter deaths.
