What Are the Warning Signs of a Carbon Monoxide Gas Leak?
Carbon monoxide (CO) is known as the “silent killer” for a reason. It’s colorless, scentless and difficult to recognize without the right tools. If it collects in your home, it can rapidly turn into a serious hazard for you and your family. So, how do you guard against something you can’t see, smell or taste?
The key is to have carbon monoxide detectors. These safety devices are the first line of defense, alerting you to the presence of CO gas before the situation becomes life-threatening. But other than a detector going off, how can you recognize if there’s a carbon monoxide leak in your home? These are 10 warning signs to keep an eye on.
1. Condensation on Windows Nearby Appliances
If you see heavy condensation on your windows, especially near a gas-powered device like a gas fireplace, this could suggest that ventilation isn't working properly. While humidity or condensation itself doesn't always mean CO, this clue warrants investigation.
2. Discoloration or Soot-Like Stains
Combustion-based appliances should have clean, clear exhaust. If you see brownish-yellow or dark stains around a heating system, fireplace or boiler, there may be combustion issues. This can be a sign of a carbon monoxide leak.
3. Exhaust Fumes Are in the House
If you start to smell exhaust fumes inside the house, you are at risk of carbon monoxide leaks. Gas-burning items like cars, charcoal grills and generators should only be used outdoors to avoid the buildup of exhaust fumes indoors.
4. Soot in or Around the Fireplace
Your fireplace should vent 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 coming back indoors.
5. Weak or No Draft in Your Chimney
Speaking of chimneys, a properly working one should have the strong airflow to fully remove smoke and other fumes. If you detect weak airflow or even no draft at all, the chimney might be blocked, pushing carbon monoxide right back indoors.
6. Discolored or Weak Flames
Gas-powered appliances should produce a distinct blue flame. When the flame is weak and yellow (and it's not a decorative gas fireplace), it can mean the gas has combustion issues and could be releasing carbon monoxide.
7. Solid Fuel Fires Burning Slowly
When your wood- or coal-fired stove is burning slower than usual or has trouble even staying on, it could have a venting problem, raising the risk 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 clue might come from your health and well-being. Symptoms of CO poisoning can be:
- Flu-like symptoms
- Headaches
- Dizziness
- Nausea or vomiting
- Shortness of breath
- Confusion
- And fatigue
If you or anyone in your family starts getting sick, especially combined with any of the above signs, move outdoors immediately and contact emergency services.
Preventing CO Leaks and Top Safety Tips
Prevention is always better than a cure, especially in the case of CO gas exposure. For the most basic safety, make sure you have carbon monoxide detectors in appropriate places. Building codes require them close to any bedrooms, on each level of your home and in rooms with gas-powered equipment. For an additional safety measure, it’s wise to install interconnected detectors so that whenever one goes off, all of them will raise the alarm. Test these detectors monthly and change them when required, about every five to seven years.
Besides using carbon monoxide detectors, follow these safety tips:
- Work with local Experts to regularly inspect your heating system, fireplace and all other fuel-burning appliances.
- Never use grills, portable generators or similar equipment inside the house or garage.
- Run the kitchen exhaust fan if you're cooking with a gas-powered oven, and avoid using these appliances for home heating.
