Daylight-saving time starts 2 a.m. Sunday, and Hamilton County's fire departments encourage residents to change the batteries in their smoke alarms and carbon monoxide detectors, test the alarms and remind friends, family, neighbors and fellow community members to do the same.

With the peak time for home fire fatalities occurring between 11 p.m. and 7 a.m. when most families are sleeping, this simple step can help save their lives and the lives of those around them.

A working smoke detector is your first line of defense in a fire.
