Daylight savings time will end on Sunday. That means everyone needs to set their clocks BACK an hour before going to bed Saturday night. Area fire departments want to remind you to make a change that could save your life and the lives of your loved ones: change the batteries in your smoke alarms and carbon monoxide detectors. Every year, preventable fires kill people nationwide, and Tennessee has one of the highest fire death rates in the nation. Non-working smoke alarms offer a false sense of protection to residents and place them at risk for death or serious injury from unwanted fires in the home. The most commonly cited cause of non-working smoke alarms is dead or missing batteries. Changing smoke alarm batteries at least twice per year is one of the simplest, most effective ways to reduce these tragic deaths and injuries. A working smoke alarm reduces the risk of dying in a home fire by almost half. Additionally, the Tennessee Fire Chiefs Association recommends replacing your smoke alarms every ten years.
