 Did you know? The risk of dying from fires in homes without smoke alarms is twice as high as in homes that have working smoke alarms. Smoke and carbon monoxide detectors can alert you to a fire or poison as carbon monoxide in your home and give you valuable escape time. These alarms save lives and prevent injuries. That's a fact. So it is critical that your smoke and carbon monoxide alarms always be in good working order. Smoke and carbon monoxide alarms should be tested once a month and the battery should be replaced once a year. Many people replace their smoke and carbon monoxide alarm batteries on Time Change Sunday. Time Change Sunday may also be a good time to remember to practice your fire escape plant. Children are especially vulnerable in house fires so every family should develop a fire escape plan and practice it at least twice a year with the entire household.
