On March 4 at 1:09pm crews from Mt. Penn and Lower Alsace (CO 4) were dispatched to 13 Butter Lane for a report of a carbon monoxide/smoke detector activation.
Upon entering the structure readings of 300+ parts per million (PPM) carbon monoxide (CO) were registered with the occupant indicating some symptoms of exposure. Crews then checked the neighboring residence with readings of 120+ PPM and that occupant also indicating exposure symptoms. Doing additional investigation revealed that the furnace at #13 was the source of the problem and it was shut down.
The occupants were evaluated and transported by Lower Alsace and Exeter ambulances to a local hospital as a precaution. Both buildings were ventilated and checked again with the assistance of UGI personnel who determined that both buildings were now clear and could be turned over to the owners.
