Common Sources of CO
Common sources of potentially dangerous levels of CO are:
• Poorly maintained furnaces, gas heaters, or fireplaces.
• Dirty or plugged chimneys, or flue exhausts.
• Poorly maintained gas, oil, or kerosene appliances.
• Internal combustion engines (e.g ., automobiles, lawnmowers, blowers).
