You probably have smoke detectors in the house, but did you know that carbon monoxide (CO) is a toxic gas that is odorless, tasteless, and invisible? It can kill you in your sleep.
Most people don’t have enough and/or don’t put detectors in the right places at home. Please take a moment to review this information provided by the Santa Clara County Fire Department.
If you need a refresher on smoke detectors placement in your house, there’s some good information on the same website.
