Introduction
Regrettably, there is a concealed hazard that many homeowners are unaware of: carbon monoxide poisoning from blocked heating system vents. Winter in Ontario is characterized by picturesque snow-covered landscapes and cozy indoor evenings. Although the majority of individuals are cognizant of the significance of installing carbon monoxide detectors in their residences, a smaller number comprehend the rapidity with which a severe snowfall can result in a life-threatening situation.
What Is Carbon Monoxide, and Why Is It So Dangerous?
When fuel burns incompletely, it produces carbon monoxide (CO), a gas that has no smell, colour, or taste. Furnaces, water heaters, gas dryers, and any other equipment that burns natural gas, propane, oil, or wood are all common sources. Under normal circumstances, these appliances safely send dangerous gases outside your home through exhaust pipes or chimneys. Carbon monoxide is dangerous since you can't see it.
People commonly call it the "silent killer" because you can't see, smell, or taste it. When you breathe in CO, it stops your blood from transporting oxygen to your organs and tissues. Even a little bit of exposure can trigger flu-like symptoms like headaches, dizziness, nausea, and confusion. Higher levels can cause unconsciousness and death in just a few minutes.

How Snow Blocks Your Vents
Modern high-efficiency water heaters and furnaces employ PVC pipes that vent horizontally through the outside walls of your home, usually just a few feet above the ground. These vents let out exhaust gases and bring in fresh air for burning. These low vents might get entirely buried when it snows a lot or when the wind blows snow against your house.
When snow builds up around vents, it causes two major concerns. First, the exhaust vent gets blocked, which keeps harmful gases from leaving your house. Second, the air intake vent is blocked, which cuts off the oxygen your heating system needs to burn fuel properly. This dual obstruction creates an ideal scenario: your furnace produces more carbon monoxide due to incomplete combustion, and this deadly gas can only return to your home.
When it's really chilly outside and your furnace runs all the time, things get much worse. The longer your heating system runs with blocked vents, the more carbon monoxide builds up in your home. Many things happen at night while families are sleeping, and it's tougher to see the signs.
Real-World Consequences
Every winter, clogged vents in Canada cause carbon monoxide emergencies that emergency services must handle. Many cases necessitate the hospitalization of entire families. Regrettably, some incidents result in fatalities. These incidents are especially sad since they could have been avoided with just a little knowledge and action.
One common situation is when people who own homes sweep their driveways and sidewalks after a winter but forget about the vents on the side of their property. Another is when snow from shovelling or plowing is piled up right against the foundation of the house, blocking the vents. Even snow rolling down the roof and landing near vents on the ground might cause serious blockages.

How to Keep Your Family Safe
Please locate the positions of your vents.
Take a walk around your house and find all of the vents on the outside. Most high-efficiency furnaces include two PVC pipes on the outside wall: one for intake and one for exhaust. Some equipment, including water heaters and gas dryers, may have their vents. Before winter comes, take pictures or write down where they are. " Beyond keeping vents clear, schedule annual furnace maintenance before winter begins. For a comprehensive guide to preparing your home for winter, check out our
Get rid of snow right away after every snowfall.
As part of your snow removal routine, clear the vents. After you've cleared your driveway and walkways, check around your house to make sure all the vents are clear. Take away at least three feet of snow from each vent in all directions. This leaves enough room for air to flow freely and stops snow from blowing back against the vents.
Be Careful When You Pile Snow
When you shovel or blow snow, don't put it against your home's foundation or near vents. Pick places to throw things out that are far away from the house. Please inform the snow removal provider about the location of your vents and kindly request that they avoid piling snow in specific areas.
Put in and take care of carbon monoxide detectors.
It's important to keep vents clear, but carbon monoxide detectors are a crucial backup safety device. Put detectors on every level of your home, especially near where you sleep. Once a month, check them and change the batteries every six months. According to the manufacturer's instructions, you should replace the whole device every five to seven years.

Be on the lookout for warning signs.
If your carbon monoxide detector goes off, pay attention. Get out right away and contact 911 from outside. Be on the lookout for symptoms even if there isn't an alarm. These include headaches, dizziness, nausea, confusion, or flu-like symptoms that get better when you leave the house. If you see condensation on your windows, soot around your furnace, or a yellow (instead of blue) flame on your burner, these could be signs of combustion problems.

Some homeowners paint the area around ground-level vents a bright colour so people can see it.
If you're repairing or installing new heating equipment, ask your contractor where to put vents. To lower the possibility of snow building up, put vents higher on walls or employ vertical venting whenever you can. isn't always possible with current systems, but it's something to think about for new installations.
