Prince George’s County firefighters and medics have been on the scene of a carbon monoxide emergency at a church since about 6:30 this evening. The location is Saint Bernard Catholic Church in the Riverdale Park area.

In a press release, PGFD Chief Spokesman Mark Brady said that the original call was for a person feeling faint and dizzy. When the first EMS unit arrived other reported similar symptoms.

Here’s more from Brady’s press release sent just before 8:00 PM:

Additional Firefighters and the Departments Hazardous Materials Team, Mass-Casualty Support Unit and Mobile Ambulance Bus were called to the scene to assist. One person reported that work on the church’s boiler had been performed earlier in the day. A gas meter detecting the level of CO in the atmosphere showed levels at 1300. A normal CO level should be around 0 – 30 parts per million (ppm). The building was evacuated and the utilities were shut off. CO levels have started to decrease.

At this point 3 patients have been transported to area hospitals, an adult female and two children, both around 10 years of age. As many as 10 additional patients are receiving oxygen, being monitored by paramedics on the scene and are being prepared for transport on-board the Departments Mobile Ambulance Bus.
