The weather is getting colder, which means that more and more people are turning on their heaters. But, with the use of heaters comes the risk of carbon monoxide (CO) exposure and poisoning. Learn why the risk of carbon monoxide exposure increases during the winter months, how to recognize signs of carbon monoxide poisoning, and how Huge Heating & Cooling can help keep you and your family safe from carbon monoxide this winter. 


What is Carbon Monoxide?

The University of Utah defines CO as an “odorless, invisible gas that is produced when gasoline, natural gas, propane, kerosene, and other fuels are not completely burned during use.” Carbon monoxide can also be caused by 


  • Automobile exhaust
  • Small gas engines
  • Camp lanterns
  • Stoves
  • Charcoal grills
  • Gas ranges
  • Furnaces 


The University of Utah further asserts that carbon monoxide is essentially created when anything that is capable of producing it, including furnaces, are “improperly adjusted and used in poorly ventilated areas.”


Why Carbon Monoxide Exposure Risk Increases in the Winter

According to the Centers for Disease Control and Prevention (CDC), “carbon monoxide (CO) exposures and poisonings occur more often during the fall and winter, when people are more likely to use gas furnaces and heaters.” Plus, in the winter, people tend to keep their windows closed, which limits the amount of fresh air they get inside their homes. 


Why Carbon Monoxide is so Dangerous

According to Mayo Clinic, CO exposure is so dangerous because it can build up in your bloodstream. When you are exposed to too much CO, it actually replaces the oxygen in your body with it, which can lead to serious health issues, including death by asphyxiation.


Signs of Carbon Monoxide Poisoning

According to Mayo Clinic, signs and symptoms of carbon monoxide poisoning may include:


  • Dull headache
  • Weakness
  • Dizziness
  • Nausea or vomiting
  • Shortness of breath
  • Confusion
  • Blurred vision
  • Loss of consciousness


If you think you or anyone in your household has been exposed to carbon monoxide, please call 911 right away.


How to Prevent Carbon Monoxide Poisoning

The good news is that there are several things you can do to prevent exposure to CO in your home. 


  1. Get a furnace tune-up. 

One of the best things you can do to prevent CO from getting into your home is to have your furnace serviced by a technician at least once a year. Not only will a technician inspect your furnace for any issues, but they can also run a carbon monoxide test to ensure that your furnace is not producing this dangerous gas. 


  1. Use CO monitors.

Ideally, you should have a CO monitor on every level of your home. If they are battery operated, make sure you check the batteries at least every six months. 


  1. Don’t let snow build up near outside vents.

If you are in an area that gets heavy snowfall, make sure you clear off the snow that may be near any outside vents.


  1. Don’t run your car in an attached garage.

If you have a garage that is attached to your home, don’t let your car run while inside the garage. If you need to warm it up before you drive it, pull it out into the driveway. 


  1. Make sure your fireplace vent is open.

If you have a fireplace, make sure the vent is open before you use it.
