Keep your home or business safe from the threat of carbon monoxide (CO) poisoning with a First Alert CO detector. Carbon monoxide is an odorless, invisible, and extremely dangerous gas which can be produced by many common household appliances. It is typically found in areas where fuel is burned, including gas, oil, kerosene, or wood. This odorless gas can become harmful and even fatal if it is released at high levels. Reduce the chances of you or your loved ones from being harmed by this fatal gas with First Alert CO detectors such as the First Alert CO410A battery powered carbon monoxide alarm featuring an easy to read backlit LED display, or the First Alert CO500CNA ONELINK battery operated carbon monoxide alarm utilizing wireless integration for effortless connectivity.
