Carbon monoxide (CO) is one of the most hazardous gases found in the home. Known as the “silent killer,” CO gas is colorless, odorless, tasteless and non-irritating, but it can lead to unconsciousness, brain damage or death. As a result, more than 400 people die of accidental carbon monoxide exposure each year, a higher fatality rate than any other type of poisoning.
As the weather cools off, you close up your home for the winter and rely on heating appliances to keep warm. This is when the risk of carbon monoxide exposure is highest. The good news is you can defend your family from carbon monoxide in several ways. One of the most efficient methods is to install CO detectors in your home. Use this guide to help you understand where carbon monoxide comes from and how to make the most of your CO alarms.
Carbon monoxide is a byproduct of incomplete combustion. Therefore, this gas is produced anytime a fuel source is ignited, like natural gas, propane, oil, charcoal, gasoline, woo, and more. Frequent causes of carbon monoxide in a house include:
No, smoke detectors do not detect carbon monoxide. Instead, they start an alarm when they sense a certain level of smoke caused by a fire. Having functional smoke detectors reduces the risk of dying in a house fire by about 55 percent.
Smoke detectors come in two basic forms—ionization detectors and photoelectric detectors. Ionization detection works best with fast-growing fires that produce large flames, while photoelectric detection is more effective with smoldering, smoky fires. Some newer smoke detectors incorporate both types of alarms in a single unit to increase the chance of sensing a fire, no matter how it burns.
Clearly, smoke detectors and CO alarms are similarly important home safety devices. If you look up at the ceiling and see an alarm of some kind, you won’t always know whether it’s a smoke detector or a carbon monoxide alarm. The visual discrepancy is based on the brand and model you have. Here are a few factors to keep in mind:
The number of CO alarms you should have depends on your home’s size, number of floors and bedroom arrangement. Follow these guidelines to ensure thorough coverage:
Depending on the model, the manufacturer may encourage monthly testing and resetting to ensure proper functionality. Also, replace the batteries in battery-powered units every six months. For hardwired units, replace the backup battery annually or when the alarm starts chirping, whichever starts first. Then, replace the CO detector entirely every 10 years or according to the manufacturer’s instructions.
It only takes a minute to test your CO detector. Read the instruction manual for directions specific to your unit, knowing that testing uses this general procedure:
Replace the batteries if the unit won’t work as expected during the test. If replacement batteries don’t change anything, replace the detector immediately.
You’re only required to reset your unit after the alarm goes off, after testing the device or after replacing the batteries. Some models automatically reset themselves within 10 minutes of these events, while others require a manual reset. The instruction manual will note which function applies.
Follow these steps to reset your CO detector manually:
If you don’t hear a beep or see a flash, try the reset again or replace the batteries. If it’s still not working, troubleshoot your carbon monoxide alarm with help from the manufacturer, or install a new detector.
Follow these steps to protect your home and family:
With the right precautions, there’s no need to fear carbon monoxide exposure in your home. In addition to installing CO alarms, it’s crucial to maintain your fuel-burning appliances, particularly as winter gets underway.
