Smoke alarms sense smoke well before you can, alerting you to danger. In the event of a fire, you may have as little as 2 minutes to escape safely. That’s why smoke alarms need to be in every bedroom, outside of sleeping areas (like a hallway), and on each level of your home, including the basement.
Carbon monoxide is an odorless, colorless gas that displaces oxygen in your body and brain and can render you unconscious before you even realize it. Without vital oxygen, you are at risk of death from carbon monoxide poisoning in a short time. CO alarms detect the presence of carbon monoxide and alert you so you can get out, call 9-1-1, and let the professionals check your home.
