Daylight Saving Time ends on Sunday, November 6, at 2 a.m. So as we set our clocks back, take the time to change the batteries in your smoke and carbon monoxide alarms. Also, check the date on your smoke alarms to ensure they are not more than ten years old, and replace them if they are. Smoke alarms save lives, but only if they work! You can also use the extra hour to make or practice your escape plan!
