What Are the Signs of a Carbon Monoxide Gas Leak?
Carbon monoxide (CO) is known as the “silent killer” for a reason. It’s invisible, odorless and tough to detect without proper tools. If it builds up in your home, it can quickly become a serious threat for you and your family. So, how do you stay safe against something you can’t see, smell or taste?
The key is to use carbon monoxide detectors. These small alarm systems are the first line of defense, warning you about the presence of CO gas before the situation becomes life-threatening. But other than a detector going off, how can you tell if there’s a carbon monoxide leak in your home? Here are 10 clues to watch out for.
1. Condensation on Windows Near Appliances
If you spot lots of condensation on your windows, namely near a fuel-burning appliance like a gas fireplace, this could mean that there’s an issue with ventilation. While condensation alone isn’t always CO-related, this clue deserves a closer look.
2. Discoloration or Soot-Like Stains
Combustion-based appliances should always have clear exhaust. If you find brownish-yellow or sooty stains around a heater or gas fireplace, there may be combustion issues. This can be a sign of a carbon monoxide leak.
3. Exhaust Fumes Are Inside
If you start to smell exhaust fumes inside the house, you are in danger of carbon monoxide symptoms. Fuel-burning appliances like cars, charcoal grills and generators should exclusively be used safely outside the home to prevent an accumulation of exhaust fumes indoors.
4. Soot in or Around Your 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 leaking back into your home.
5. Increasingly Weak or No Draft from the Chimney
Staying on the topic of chimneys, a properly working one needs the steady pull to fully remove smoke and other fumes. If you find weak airflow or even no draft at all, the chimney may be clogged, sending carbon monoxide back into your home.
6. Yellow or Inconsistent Flames
Most gas-burning appliances should have a clear blue flame. When the flame is yellow or flickering (and you don’t have a decorative gas fireplace), it means the gas is burning inefficiently and may be releasing carbon monoxide.
7. Solid Fuel Fires Burn More Slowly
In situations where your wood or coal stove is taking longer to burn or has trouble maintaining a flame, it could have a ventilation issue, increasing the risk of CO buildup.
Symptoms of CO Poisoning
If you miss the other signs of a carbon monoxide leak in time, the next clue might come from your health and well-being. 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 home experiences these symptoms, especially combined with any of the warning signs listed above, get fresh air immediately and call 911.
Prevention and Safety Tips
Prevention is always better than a cure, especially when it comes to carbon monoxide. For the most basic safety, make sure you have carbon monoxide detectors in appropriate places. Building codes require them outside every bedroom, on each level of your home and in rooms with appliances like a gas stove or water heater. For an additional safety measure, it’s wise to set up interconnected detectors so that as soon as one goes off, all of them will alarm you as well. Perform monthly testing and swap them out when necessary, usually every five to seven years.
Along with having enough carbon monoxide detectors, keep these safety precautions in mind:
- Work with local Experts to regularly inspect your heating system, gas or wood fireplace, and all other fuel-burning appliances.
- Avoid using grills, portable generators or similar equipment inside, especially in small spaces.
- Use your stove vent when cooking with a gas stove, and avoid using these appliances for home heating.
