Introduction
Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that can be fatal if inhaled. It is produced by the incomplete combustion of fuels, such as natural gas, propane, and wood. CO can build up in enclosed spaces, such as homes, apartments, and garages, and pose a serious health risk.

Carbon monoxide detectors are essential for protecting yourself and your family from CO poisoning. These devices sound an alarm when CO levels reach dangerous levels. It is important to test your carbon monoxide detector regularly to ensure that it is working properly.
How to Test a Carbon Monoxide Detector with a Candle
One way to test a carbon monoxide detector is to use a candle. Here are the steps:
- Light a candle and place it near the carbon monoxide detector.
- Wait 30 seconds to 1 minute.
- If the carbon monoxide detector alarms, it is working properly.
If the carbon monoxide detector does not alarm, there may be a problem with the detector or the candle may not have produced enough CO. You should test the detector again using a different method, such as a CO test kit.
Other Methods for Testing a Carbon Monoxide Detector
In addition to using a candle, there are several other methods for testing a carbon monoxide detector. These methods include:
- CO test kit: A CO test kit can be purchased at most hardware stores. The kit contains a small amount of CO gas that you can release into the air near the carbon monoxide detector. If the detector alarms, it is working properly.
- Carbon monoxide simulator: A carbon monoxide simulator is a device that produces a small amount of CO gas. The simulator can be used to test the carbon monoxide detector without releasing any CO into the air.
- Professional testing: A qualified technician can test your carbon monoxide detector using a specialized instrument. This is the most accurate method of testing a carbon monoxide detector.
How Often Should You Test Your Carbon Monoxide Detector?
You should test your carbon monoxide detector at least once a month. You should also test the detector after any event that could have produced CO, such as a fire or a power outage.
Conclusion
Carbon monoxide detectors are essential for protecting yourself and your family from CO poisoning. It is important to test your carbon monoxide detector regularly to ensure that it is working properly. There are several different methods for testing a carbon monoxide detector. You should choose the method that is most convenient for you and your family.
Additional Tips for Preventing CO Poisoning
In addition to testing your carbon monoxide detector regularly, there are several other things you can do to prevent CO poisoning. These include:
- Never use a generator indoors. Generators produce CO, which can build up to dangerous levels in enclosed spaces.
- Never burn charcoal or wood indoors. Charcoal and wood also produce CO.
- Keep your gas appliances in good working order. Gas appliances, such as stoves, ovens, and water heaters, can produce CO if they are not properly maintained.
- Install a CO detector in every bedroom and living space. This will help to ensure that you are warned of CO leaks even if you are sleeping or away from the home.
