Where Carbon Monoxide Comes From at Home

Someone warms up the car in the garage on a cold morning. A furnace kicks on overnight while everyone’s asleep. Or maybe someone used the fireplace, and the flue didn’t quite open all the way. Nothing dramatic. Nothing that feels super dangerous. But carbon monoxide is the kind of danger that shows up quietly. 
The good thing is that many of these situations are preventable. When you understand where CO comes from, you’re much more likely to catch a problem early — or avoid one altogether. 

Where CO Can Show Up 

Carbon monoxide doesn’t usually come from something unusual. Most of the time, it’s produced by  appliances & equipment you use all the time — especially anything that burns fuel:

• Dryers 
• Water heaters, furnaces and boilers 
• Fireplaces (wood-burning & gas) and wood stoves 
• Gas stoves and ovens 
• Motor vehicles and boats 
• Grills, camp stoves and fuel-burning lanterns 
• Generators 
• Power tools and lawn equipment

Proper installation, ventilation and regular maintenance matter. When everything is working the way it should, you can use these things safely.  

Simple Steps Makes a Big Difference

Knowing the sources is the first step. The next is making sure your home is set up to catch carbon monoxide. Installing CO detection on every level of your home and outside sleeping areas is a smart move to help ensure the first sign of CO is an alarm — not symptoms.
