Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that can be deadly to humans and pets. It’s often produced by fuel-burning appliances such as furnaces, fireplaces, stoves, water heaters, and even running vehicles in attached garages.
If you’re a homeowner with gas, oil, wood-burning, or propane appliances, having a carbon monoxide detector isn’t just a smart idea — it’s essential for your family’s safety.
Why Carbon Monoxide Detectors Are So Important
Carbon monoxide is known as the “silent killer” because you can’t see, smell, or taste it. High levels can build up quickly without any warning, especially if something goes wrong with one of your appliances or vents.
Symptoms of CO poisoning include:
- Headaches
- Dizziness
- Nausea
- Confusion
- Shortness of breath
- In severe cases: loss of consciousness or death
Children, older adults, and people with existing health conditions are especially vulnerable to carbon monoxide poisoning.
Where Should You Install Carbon Monoxide Detectors?
The National Fire Protection Association (NFPA) recommends placing CO detectors:
- On every level of your home
- Near or inside bedrooms
- Near any attached garage or furnace room
For example, in a typical three-bedroom, two-bath home with an attic and basement, you should install at least four carbon monoxide detectors.
If you’re unsure where to place them or need help installing detectors, I’m happy to connect you with a local professional.
Common Sources of Carbon Monoxide in Homes
These appliances or situations can produce dangerous levels of carbon monoxide:
- Gas, oil, or propane furnaces and water heaters
- Gas stoves and ovens
- Fireplaces (both gas and wood-burning)
- Charcoal grills (when used indoors — never do this!)
- Portable space heaters (if unvented)
- Vehicles idling in attached garages
How to Maintain Your CO Detectors
Just like smoke detectors, CO detectors require maintenance and regular replacement:
✅ Replace every 5–7 years (check the manufacturer date on the back)
✅ Test monthly to ensure the alarm works
✅ Replace batteries twice a year, such as when daylight saving time changes
✅ Look for the UL certification to ensure your detector meets safety standards
Some detectors are plug-in models, others are hardwired, and some are battery-powered — choose what works best for your home setup.
CO Detector Requirements When Buying or Selling a Home
Some states require carbon monoxide detectors to be installed before a home can be sold — and in some cases, inspected by local fire departments.
In Oklahoma, there are no current regulations requiring CO detectors in residential properties. That means buyers need to take it upon themselves to install or inspect detectors when purchasing a home.
How to Prevent Carbon Monoxide Buildup in Your Home
Follow these safety tips to reduce the risk of CO exposure:
- Schedule regular inspections for all fuel-burning appliances and chimney systems
- Ensure proper ventilation for all appliances
- Never use charcoal grills indoors
- Don’t leave vehicles running in a garage, even with the door open
- Don’t use unvented combustion heaters overnight or while sleeping
- Follow the manufacturer’s instructions for every appliance in your home
