Acorn-clogged heater, CO detector created grave danger

December 7, 2012 (Ramona)--Three people were taken by ambulance to UCSD to be treated for high levels of carbon monoxide yesterday. Fortunately, they were released later and are expected to recover. But their ordeal is a reminder of the importance of inspecting and maintaining furnaces, as well as having a working carbon monoxide detector, County officials warn.

At approximately 9:30 a.m. Thursday, a 911 call was made from the 24000 block of Highway 78 reporting a medical emergency of a patient that was possibly cardiac in nature. Shortly after a second person in the same household became ill, the person making the 911 call became unresponsive to dispatchers.
