What Are the Indicators of a Carbon Monoxide Leak?

Carbon monoxide (CO) is called the “silent killer” for a reason. It’s colorless, scentless and hard to detect without the right tools. If it collects in your home, it can swiftly pose a danger for you and your family. So, how do you protect yourself against something you can’t find with your senses?

The key is to install carbon monoxide detectors. These alarms are the initial line of defense, warning you about the presence of CO gas before the situation gets dangerous. But aside from a detector going off, how can you tell if there’s a carbon monoxide leak in your home? Below are 10 warning signs to keep an eye on.

Weaker or No Draft from Your Chimney

Staying on the topic of chimneys, a properly working one needs the strong airflow to fully ventilate smoke and other fumes. If you notice a weak draft or even no draft at all, your chimney might be clogged, sending carbon monoxide right back indoors.

Solid Fuel Fires Aren’t Burning as Fast

If your wood or coal stove begins taking longer to burn or has trouble even staying on, it could have a venting problem, increasing the risk of CO buildup.

Condensation on Windows Nearby Appliances

If you see lots of condensation on your windows, particularly near a gas-powered device like a gas fireplace, this could suggest that ventilation isn’t working properly. While condensation by itself may not mean CO, this clue deserves a closer look.

Discolored or Flickering Flames

Most gas-burning appliances should produce a steady blue flame. Whenever the flame is weak and yellow (and it isn’t a decorative gas fireplace), it means the gas isn’t burning properly and might be releasing carbon monoxide.

Discoloration or Soot-Like Stains

Similarly, fuel-powered appliances should have unobstructed ventilation. If you see brownish-yellow or sooty stains around a heater or gas fireplace, it could mean something’s wrong with the combustion process. This can signal a carbon monoxide risk.

Soot in or Around a Gas Fireplace

Your fireplace vent should remove smoke and other gases up and out the chimney. Finding soot inside or around the fireplace is cause for concern, especially if there’s excessive amounts. A clogged chimney could be the reason carbon monoxide is backdrafting indoors.

Exhaust Fumes Appear Indoors

If you start to notice exhaust indoors, you are at risk of carbon monoxide exposure. Gas-burning items like cars, charcoal grills and generators should exclusively be operated outside to avoid the buildup of exhaust fumes indoors.

Preventing CO Leaks and Top Safety Tips

Taking all the proper precautions is key, especially when it comes to carbon monoxide. First, check that there are carbon monoxide detectors in appropriate places. Building codes require them outside every bedroom, on each level of the house and in rooms with gas-powered equipment.

For an additional safety measure, it’s wise to use interconnected detectors so that if one goes off, all of them will raise the alarm. Check your alarms monthly and replace them as needed, generally every five to seven years.

Besides using carbon monoxide detectors, don’t forget these other tips:

  • Work with local Experts to regularly inspect your heating system, gas or wood fireplace, and all other fuel-burning appliances.
  • Never use grills, portable backup generators or similar equipment indoors or in enclosed spaces.
  • Turn on the range hood whenever you’re cooking with a gas-powered oven, and never use these appliances as a heat source.

Symptoms of CO Poisoning

If you don’t catch the other signs of a carbon monoxide leak in time, the next one might come from your health and well-being. Symptoms of CO poisoning may involve:

  • Flu-like symptoms
  • Headaches
  • Dizziness
  • Nausea or vomiting
  • Shortness of breath
  • Confusion
  • And fatigue

If you or anyone in your family suddenly feels sick, especially combined with any of the warning signs listed above, leave the house right away for fresh air before you dial 911.
