Where Should Carbon Monoxide Detectors Be Installed? A Crucial Guide for Safety

where should carbon monoxide detectors be installed

Carbon monoxide (CO) is an odorless, colorless, and tasteless gas that can be deadly when inhaled in high concentrations. It is produced by the incomplete combustion of fossil fuels such as natural gas, oil, and coal. Since it is impossible to detect without the help of technology, installing carbon monoxide detectors in the right locations within your home or workplace is of paramount importance. In this blog, we will discuss the key areas where carbon monoxide detectors should be installed to ensure the safety and well-being of yourself and your loved ones.

Near Sleeping Areas

One of the most critical locations for a carbon monoxide detector is near sleeping areas. When people are asleep, they are particularly vulnerable to the effects of carbon monoxide poisoning, as they may not wake up in time to recognize the symptoms. By installing a detector near bedrooms, you can ensure early detection of any CO leaks during the night and provide ample time to evacuate the premises.

On Each Floor

To maximize safety, it is important to have carbon monoxide detectors on every level of your home or workplace. Since CO can mix and distribute evenly throughout a building, installing detectors on multiple floors ensures comprehensive coverage. This is especially crucial in multi-story buildings, where CO leaks on one floor may not be immediately noticeable on other levels.

Near Fuel-Burning Appliances

Carbon monoxide is commonly produced by fuel-burning appliances such as gas furnaces, water heaters, stoves, and fireplaces. Install detectors near these appliances to monitor the levels of CO emissions. Placement near fuel-burning appliances will enable prompt detection and alert you to potential leaks or malfunctions, giving you an opportunity to address the issue before it becomes hazardous.

Garages and Attached Structures

If your home has an attached garage or any other structure that contains fuel-burning equipment, it is essential to install a carbon monoxide detector in that area as well. Vehicles, generators, and other machinery that use gasoline or diesel can release dangerous levels of carbon monoxide, especially in enclosed spaces. Detecting any CO accumulation in these areas will help prevent it from seeping into the rest of the building.

Basements or Crawl Spaces

Basements and crawl spaces often house fuel-burning appliances like boilers, water heaters, or furnaces. These areas may also be prone to water heater leaks or gas line issues, increasing the risk of carbon monoxide leaks. Installing a CO detector in the basement or crawl space is crucial to detecting any gas leaks early and preventing the gas from spreading to the rest of the building.

Close to the Bedrooms of Vulnerable Individuals

If you have individuals in your home who are more susceptible to the effects of carbon monoxide, such as the elderly, young children, or individuals with respiratory conditions, consider placing a detector near their bedrooms. This will ensure their safety and allow for swift action in the event of a CO leak.

Follow the manufacturer’s recommendations.

While the above guidelines provide general recommendations, it is vital to read and follow the manufacturer’s instructions that accompany your specific carbon monoxide detectors. Manufacturers may have specific recommendations regarding optimal placement and the number of detectors required based on the size and layout of your home or workplace.


Installing carbon monoxide detectors in the right locations is essential for the safety of your household or workplace. By placing detectors near sleeping areas, on each floor, near fuel-burning appliances, in garages and attached structures, in basements or crawl spaces, and near the bedrooms of vulnerable individuals, you can maximize your protection against the dangers of carbon monoxide. Remember to regularly test and maintain your detectors according to the manufacturer’s instructions to ensure they are in optimal working condition. Stay informed and stay safe. If you’re still concerned or suspect a leak, don’t hesitate to contact professional help right away. It’s better to take preventive measures than miss an opportunity to prevent serious injury from exposure. Don’t forget to contact us today for more information.
