Carbon monoxide (CO) is one of the most hazardous gases found in the home. Dubbed the “silent killer,” CO gas is colorless, odorless, tasteless and non-irritating, yet it can cause unconsciousness, brain damage or death. As a result, more than 400 people die of accidental carbon monoxide exposure each year, a steeper fatality rate than any other type of poisoning.
As the weather cools off, you close up your home for the winter and count on heating appliances to stay warm. This is when the risk of carbon monoxide exposure is highest. The good news is you can safeguard your family from carbon monoxide in several ways. One of the most effective methods is to install CO detectors throughout 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. Because of this, this gas is generated whenever a fuel source is burned, including 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 begin an alarm when they sense a certain level of smoke generated by a fire. Having reliable smoke detectors reduces the risk of dying in a house fire by nearly 55 percent.
Smoke detectors come in two main forms—ionization detectors and photoelectric detectors. Ionization detection works best with quick-moving fires that emit large flames, while photoelectric detection is more effective with smoldering, smoky fires. Some newer smoke detectors come with 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 inspect the ceiling and see an alarm of some kind, you may not know whether it’s a smoke detector or a carbon monoxide alarm. The visual contrast depends on the brand and model you want. Here are some factors to keep in mind:
The number of CO alarms you require is determined by your home’s size, number of floors and bedroom arrangement. Use 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 comes first. Then, replace the CO detector entirely every 10 years or according to the manufacturer’s guidelines.
It only takes a minute to test your CO sensor. Check 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 make a difference, replace the detector immediately.
You only need to reset your unit when the alarm goes off, after testing the device or after changing the batteries. Some models automatically reset themselves within 10 minutes of these events, while others require a manual reset. The instruction manual should 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 assistance from the manufacturer, or replace the 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, especially as winter gets underway.
