If you could do something in 30 seconds that could save your life, why wouldn't you do it? That's how long it takes to replace the battery in your smoke alarm.

As part of the national campaign "Change Your Clocks, Change Your Battery," Rural Metro Fire Department is reminding homeowners to take that important step when Daylight Saving Time starts or ends. 

According to the IAFC, 95 percent of American homes have smoke alarms, 20 percent of alarms do not work due to worn or missing batteries. Most fire-related deaths happen in homes without working smoke alarms. The peak time for home fire fatalities is between 10 p.m. and 6 a.m. when most families are sleeping. A working smoke alarm can often provide the critical extra seconds people need to get out safely.

In addition to changing smoke alarm batteries, Rural Metro Fire reminds residents that smoke detectors should be replaced every 10 years and recommends testing smoke alarms once a month by pushing the test button. Residents should also change the batteries in their flashlights regularly and plan two escape routes from their homes in the event of a fire.
