Carbon monoxide and smoke safety facts
Carbon monoxide (CO) is odorless, tasteless and invisible. If you don't already have carbon monoxide alarms on every level of your home, it's a good idea to install them. You may want to put additional alarms in sleeping areas.
Residential smoke alarms help you detect fire hazards early. They can save lives, prevent injuries and minimize property damage. Be sure to install smoke alarms on every floor of your home.
