From Harford County government:
The Harford County Department of Emergency Services is reminding citizens of Harford County to take time this weekend to change the batteries in their smoke alarms when they change their clocks for Daylight Saving Time. Daylight Saving Time officially begins Sunday, March 10 at 2:00 a.m.
“A working smoke alarm in a home is a vital component of fire safety for an individual or family,” Acting Director Russell J. Strickland said. “Battery powered smoke alarms should be checked routinely and batteries replaced every six months to ensure they work in the event of a fire or similar emergency,” Strickland remarked.
The Harford County Department of Emergency Services in cooperation with the Harford County volunteer fire and EMS service also recommends citizens prepare an emergency evacuation plan from their home in the event of a fire or other emergency situation.
“The best way to survive a home fire is to be properly prepared; and that includes maintaining working smoke alarms in every home. It is not only the law, but the right thing to do for you, your family and loved one,” Strickland added.
