On May 6, 2002, a 38-year-old male volunteer Fire Fighter (FF) was dispatched by his combination fire department (FD) (he was also a member of another career FD) to a mobile home fire near his home. After responding and assisting with fire suppression, he returned home. At some time during the day, he suffered an unwitnessed sudden cardiac death. He was found by a friend in the evening. No resuscitation measures were initiated and the FF was pronounced dead at the scene by the County Coroner. The death certificate, completed by the County Coroner, and the autopsy, performed by the Medical Examiner, listed “cardiac arrhythmia” as the immediate cause of death due to “stress of fighting fire” and “cardiomegaly with dilatation” as contributing factors.
