What Are the Warning Signs of a Carbon Monoxide Leak?
Carbon monoxide (CO) is called the “silent killer” for a reason. It’s invisible, scentless and difficult to detect without proper tools. If it collects in your home, it can rapidly turn into a serious threat 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 small alarm systems are the first line of defense, alerting you to the presence of CO gas before the situation gets dangerous. But other than a detector going off, how can you tell if there’s a carbon monoxide leak in your home? Below are 10 warning signs to be aware of.
1. Condensation on Windows Closest to Appliances
If you notice lots of condensation on your windows, especially near a combustion-based system like a gas fireplace, this could suggest that there’s an issue with ventilation. While humidity or condensation itself doesn’t always mean CO, this clue warrants investigation.
2. Yellow or Brown Stains
Combustion-based appliances should always have clear exhaust. If you find brownish-yellow or sooty stains around a heater or gas fireplace, combustion isn’t happening as it should. This can signal a carbon monoxide leak.
3. Exhaust Fumes Appear Indoors
If you can notice exhaust inside the house, you are at risk of carbon monoxide leaks. Gas-burning items like cars, charcoal grills and generators should always be operated outside to prevent an accumulation of exhaust fumes indoors.
4. Soot in or Around a Gas Fireplace
Your fireplace vent should remove smoke and other gases through the chimney. Noticing more soot or grime is cause for concern, especially if there’s excessive amounts. A blocked chimney vent could be why carbon monoxide is backdrafting indoors.
5. Weak or No Draft from the Chimney
Speaking of chimneys, a properly working one should have the steady pull to fully ventilate smoke and other fumes. If you find weak airflow or even no draft at all, your chimney may be obstructed, pushing carbon monoxide right back indoors.
6. Discolored or Inconsistent Flames
All appliances that use gas should have a clear blue flame. When the flame is weaker and yellow (and it’s not a decorative gas fireplace), it can mean the gas isn’t burning properly and could be emitting carbon monoxide.
7. Solid Fuel Fires Aren’t Burning as Fast
If your wood or coal stove begins struggling to burn all the way through or has trouble staying lit, it could have a problem with airflow, increasing the risk of CO buildup.
Common Health Symptoms of CO Poisoning
If you don’t catch the other signs of a carbon monoxide leak in time, the next one could come from your health. Symptoms of CO poisoning include:
- Flu-like symptoms
- Headaches
- Dizziness
- Nausea or vomiting
- Shortness of breath
- Confusion
- And fatigue
If you or anyone in your household suddenly feels sick, especially together with any of the above signs, leave the house right away for fresh air before you dial 911.
Prevent CO Poisoning and Gas Leaks with These Safety Tips
Prevention is always better than a cure, especially regarding carbon monoxide. For the most basic safety, check that there are carbon monoxide detectors in appropriate places. Building codes mandate them in hallways near all bedrooms, on each level of the house and in rooms with fuel-burning appliances. For extra safety, it’s smart to set up interconnected detectors so that if one detects CO, all of them will raise the alarm. Perform monthly testing and change them when required, about every five to seven years.
In addition to installing and maintaining carbon monoxide detectors, follow these safety tips:
- Hire a professional to regularly inspect your heating system, fireplace and all other fuel-burning appliances.
- Don’t allow anyone to use grills, backup generators or similar equipment inside, especially in small spaces.
- Use your stove vent whenever you’re cooking with a gas stove, and avoid using these appliances to try and heat your home.
