Key Takeaways
- Carbon monoxide can quickly accumulate when fuel-burning appliances, vehicles, or machines are used improperly or without proper ventilation.
- You can reduce the risk of CO poisoning by installing detectors in key areas of your home and keeping all fuel-burning appliances well-maintained.
- Arlo Secure adds extra protection by detecting CO alarm sounds and sending instant alerts to your phone, even when you’re away.
In the United States, more than 100,000 people visit the emergency department each year due to accidental carbon monoxide (CO) poisoning. Luckily, there are a number of steps you can take to reduce the risk of carbon monoxide poisoning for you and your family. From knowing how CO poisoning happens to having the best safeguards in place, learn all about preventing carbon monoxide poisoning.
What is carbon monoxide (CO)?
Carbon monoxide, also known as CO, is often called the “invisible killer” because it’s a colorless, odorless, poisonous gas. Unlike natural gas, CO is often created when fuel is burned in low levels of oxygen.
What causes carbon monoxide in or near your house?
Vehicles, machines, and appliances that burn any type of fuel (gasoline, natural gas, propane, wood, oil, charcoal) can produce carbon monoxide in or near your house if they’re used improperly, not maintained, or poorly ventilated. Watch for these CO creators at home:
- Malfunctioning or poorly ventilated appliances. Fuel-burning devices like furnaces, water heaters, fireplaces, and stoves can produce CO if they’re damaged or not vented properly.
- Running vehicles or engines near the home. Cars, generators, or gas-powered tools running in or near garages can quickly send CO into the house.
- Blocked or damaged venting systems. Chimneys or vents clogged by debris, nests, or ice can trap CO and push it back indoors.
- Using fuel-burning devices indoors. Charcoal grills, propane heaters, or camp stoves create CO and are unsafe to use in enclosed spaces.
- Nearby construction or outdoor sources. Construction equipment or vehicles running close to your home can allow CO to drift inside.
- Poor home ventilation. Tightly sealed or poorly ventilated homes can trap CO when any fuel-burning device malfunctions.
Here are the best ways to prevent carbon monoxide poisoning.
From choosing the right security system to knowing where to install CO detectors, let’s explore several ways to help prevent carbon monoxide poisoning.
Install CO alarms from day one.
If you don’t already have one, install a battery-operated or battery back-up CO detector in your home. When you change the time on your clocks each spring or fall, set a reminder to also replace or change the battery. If the detector sounds for any reason, leave your home immediately and call 911. If you suspect carbon monoxide (CO poisoning) or feel a headache, dizziness, nausea, or lightheadedness, immediately leave the premises, call the fire department, and seek medical help.
Protect your family with smart CO detector placement.
Where should you place carbon monoxide detectors in your home? The CDC recommends installing a carbon monoxide detector near every sleeping area. Here’s a quick list of all the best places to install your CO detectors:
- Outside every bedroom or sleeping area
- On every level of the home, including the basement
- Near—but not right next to—fuel-burning appliances (within about 10–15 feet)
- By the door to an attached garage
- On a wall at eye level or higher, or on the ceiling
As for how to install a CO detector, it can often be as simple as attaching the device to a wall or ceiling with the included mounting hardware.
Regularly service fuel-burning appliances, and use them in well-ventilated areas.
Always have your heating system, water heater, or any other gas, oil, or coal-burning appliances serviced by a qualified technician every year. Never use charcoal- or gasoline-burning devices in enclosed spaces where there is minimal ventilation or fresh air. Avoid using a charcoal grill, camp stove, or generator inside your home. (That includes the basement, garage, or even near a window.)
Plus, experts recommend you avoid using a portable generator, pressure washer, or any gasoline powered engine less than 20 feet from any door, vent, or window. To keep the generator at a safe distance, try using a 20-foot or longer extension cord.
