Belinda Coble, 61, was being administered oxygen at her home in Nash County, while she was smoking. The cigarette ignited the tank, sparking a small explosion and fire. Coble’s husband was asleep in a separate room at the time of the incident. The sound of the explosion woke him up and he quickly extinguished the fire. He called 911 but when responders arrived at the scene, Coble was dead.
