Jefferson City Fire Department officials are reminding residents about the potential dangers of carbon monoxide poisoning after an accident Thursday morning. Three people were treated for non-life-threatening injuries after the Fire Department responded to a carbon monoxide alarm just before 8 a.m. in the 3800 block of Terra Bella Drive, according to JCFD reports. Firefighters were informed while en route that one patient had difficulty breathing, but everyone in the house was sick for some reason. Firefighters found three residents in differing states of distress and a carbon monoxide reading far in excess of safe levels. The apartment was evacuated and ventilated, and adjoining apartments were checked for carbon monoxide. No other problems were found. The occupants were evaluated and transported by EMS as a precaution.
