What Are the Signs of a Carbon Monoxide Gas Leak?
Carbon monoxide (CO) is called the “silent killer” for a reason. It’s invisible, odorless and difficult to recognize without proper tools. If it accumulates in your home, it can swiftly pose a serious threat for you and your family. So, how do you guard against something you can’t find with your senses?
The key is to use carbon monoxide detectors. These safety devices are your initial line of defense, notifying you of 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? These are 10 clues to be aware of.
1. Condensation on Windows Closest to Appliances
If you notice heavy condensation on your windows, particularly near a fuel-burning appliance like a gas fireplace, this could indicate that there’s an issue with ventilation. While condensation by itself may not mean CO, this still should be checked out.
2. Discoloration or Soot-Like Stains
Fuel-powered appliances should have clean, clear exhaust. If you see brownish-yellow or sooty stains around a furnace, fireplace or water heater, there may be combustion issues. This may point to a carbon monoxide risk.
3. Exhaust Fumes Indoors
If you can smell exhaust fumes indoors, you are at risk of carbon monoxide symptoms. Gas-burning items like cars, charcoal grills and generators should always be used outdoors to reduce the risk of exhaust fumes indoors.
4. Soot in or Around a Natural Gas-Burning Fireplace
Your fireplace vent should remove smoke and other gases up and out the chimney. Seeing soot buildup around your fireplace is a red flag, especially if there’s more than usual. A blocked chimney vent could be the culprit for why carbon monoxide is leaking back into your home.
5. Increasingly Weak or No Draft in the Chimney
Speaking of chimneys, a properly working one should have the strong airflow to fully ventilate smoke and other fumes. If you detect a weak draft or even no draft at all, your chimney could be blocked, sending carbon monoxide back into your home.
6. Discolored or Weak Flames
Gas-powered appliances should have a clear blue flame. When the flame is weak and yellow (and it’s not a decorative gas fireplace), it can mean the gas is burning inefficiently and could be producing carbon monoxide.
7. Solid Fuel Fires Burning Slowly
If your wood- or coal-fired stove begins burning slower than usual or has trouble maintaining a flame, it could have a problem with airflow, heightening the possibility of CO buildup.
Symptoms of CO Poisoning
If you fail to notice the initial warning signs of a carbon monoxide leak in time, the next one might come from your body. 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 family experiences these symptoms, especially alongside any of the previously mentioned clues, get fresh air immediately and call 911.
Prevent CO Poisoning and Gas Leaks with These Safety Tips
Prevention is always better than a cure, especially in the case of carbon monoxide. To start, ensure you’ve installed carbon monoxide detectors in appropriate places. Building codes require them in hallways near all bedrooms, on each floor of the house and in rooms with fuel-burning appliances. For extra safety, it’s best to install interconnected detectors so that if one detects CO, all of them will raise the alarm. Perform monthly testing and change them when required, approximately every five to seven years.
Along with having enough carbon monoxide detectors, keep these safety precautions in mind:
- Schedule a certified technician to regularly inspect your heating system, gas or wood fireplace, and any other fuel-burning appliances.
- Avoid using grills, portable generators or similar equipment indoors or in enclosed spaces.
- Run the kitchen exhaust fan when cooking with a gas-fired oven or stove, and avoid using these appliances for home heating.
