Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is highly toxic to humans and pets in both low and high concentrations. It is a byproduct of burning natural gas, propane, diesel fuel, charcoal, wood, and other combustible materials.

For decades, we have assumed CO poisoning was the result of inhaling CO in high concentrations (30-50 parts per million). Research is now telling us that long term, low level (5-15ppm) CO inhalation is every bit as dangerous. We now know that low levels of CO inhalation over time can affect heart rhythms, cause strokes, mental decline, and Parkinson’s like conditions.

CO is a microscopic molecule. It can freely migrate through any openings and has been known to migrate through drywall and other porous wall materials.  

What you can do:

1. Have your CO producing appliances properly installed, vented, and periodically inspected to ensure the appliance is working efficiently and any CO is being vented away from living spaces.

2. Ensure if you are operating a generator to make sure it is at least 20’ away from any structure, and never operated inside.

3. When barbecuing or making an outdoor fire (e.g., fire pit, chiminea, etc.), be sure to be 20’ away from any living spaces.

4. Never run your vehicle or any other hydrocarbon motor powered device indoors.

5. Buy, install and properly maintain a CO detector.

6. If your CO detector goes off, do not ignore it. Call 911 and get outside to fresh air.

7. If you experience flu-like symptoms, do not ignore the possibility that you might be experience CO poisoning. Many CO poisoning events are misdiagnosed.

8. When in doubt, call 911
