Every year, at least 430 Americans die from accidental carbon monoxide (CO) poisoning. Thousands more go to the emergency room with CO-related illnesses. CO is a colorless, odorless, tasteless gas produced by furnaces, stoves, gas heaters, kerosene heaters, lanterns and automobile exhaust. It can also be produced by faulty chimneys, fireplaces and portable generators. Carbon monoxide detectors are important for detecting this toxic gas.

Most CO detectors are similar to smoke alarms except that they sense levels of carbon monoxide and sound an alarm when a high concentration is detected. They must be tested monthly by pressing the test button and replacing batteries or detectors when needed. Some units also have a digital display showing the current reading of CO in parts per million.

How to Properly Install a CO Detector in Your Home

CO Detectors are required in some states and Canada. For commercial and residential buildings, they are often installed along with fire detectors to provide more complete protection for building occupants. Some manufacturers offer single devices that combine both fire and CO detection, which reduces installation costs, eliminates the need to install separate devices and simplifies maintenance.

CO detectors should be placed on each floor of a sleeping area, near the bedrooms and within 15 feet of combustion appliances, according to the manufacturer’s instructions. They should not be installed in areas where a lot of cooking or bathing takes place. Since CO’s molecular weight is the same as air, it distributes rapidly throughout a room. They should be installed in a spot where they will remain clean, out of children’s reach and not subject to dust or other obstructions.
