FAQs About Carbon Monoxide Detectors
What will set off a carbon monoxide detector?
Carbon monoxide (CO) detectors are triggered by the presence of CO gas, which can come from:
Malfunctioning fuel-burning appliances (e.g., furnaces, water heaters, stoves).
Running vehicles or generators in enclosed spaces (e.g., garages).
Blocked chimneys or vents preventing proper ventilation.
Gas-powered tools or grills used indoors.
Low-level leaks over time or sudden high concentrations.
What are carbon monoxide detectors used for?
They alert occupants to dangerous levels of carbon monoxide, an odorless, colorless, and toxic gas. Their purpose is to prevent CO poisoning by providing early warnings, allowing evacuation and intervention before health effects (like unconsciousness or death) occur.
How do you know if there is carbon monoxide in your house?
The primary indicator is a CO detector alarm. Physical symptoms of poisoning (headaches, dizziness, nausea, confusion, or fatigue) may also signal exposure. Without a detector, CO is undetectable, as it lacks smell, taste, or visibility.
Do you need a carbon monoxide detector in your house?
Yes, if your home has fuel-burning appliances (gas, oil, coal, wood), a fireplace, or an attached garage. Many building codes and safety organizations (e.g., NFPA, CDC) recommend installing them. Laws in some regions mandate detectors for residential safety.
What should I do if my carbon monoxide detector goes off?
Evacuate immediately and ensure others/pets leave too.
Call emergency services (e.g., 911 or fire department) from outside.
Do not re-enter until professionals confirm the area is safe.
Seek medical attention if symptoms arise.
Have a qualified technician inspect appliances/venting systems afterward.
Where should I install a carbon monoxide detector?
Near sleeping areas to ensure alarms are heard at night.
On every level of the home, including basements.
At least 15 feet away from fuel-burning appliances to avoid false alarms.
Avoid placing in bathrooms, humid areas, or direct sunlight.
Follow the manufacturer’s guidelines for optimal placement and maintenance.
Always ensure detectors are tested monthly, batteries replaced annually, and units replaced every 5–10 years (check expiration dates). CO detectors complement smoke alarms but serve distinct roles—install both for comprehensive safety.
