Installing and maintaining carbon monoxide (CO) alarms can save your life. Luckily, they’re inexpensive and easy to install.
CO alarms are needed for any home with fuel-burning appliances such as a furnace, water heater, range, cooktop, or grill. Even those living in all-electric homes should install CO alarms, because CO can seep into the house from an attached garage or if a backup generator is used too close to your living quarters in the event of a power outage.
You’ll need smoke alarms that detect flaming and smoldering fires for each bedroom, with at least one alarm installed on each floor, including a finished attic and the basement. You should also have a CO alarm on each living level, in the basement, and near (not inside) an attached garage.
