New York City Fire Department officials are telling children it is time to change the batteries in their homes’ smoke alarms, with the return of Daylight Standard Time.

Daylight Saving Time ends tomorrow at 2 a.m., which means New Yorkers should turn their clocks back one hour before going to bed tonight.

Fire Commissioner Salvatore Cassano was joined by other fire officials outside the Hilton Hotel in Times Square on Friday to tell kids to switch the batteries in their alarms when Daylight Saving Time ends this weekend.

The FDNY Fire Safety Education unit says 70 percent of fire deaths come from homes without a working smoke alarm.

“The most important thing you can do is what the commissioner asked you to do, and that is to go home and make sure the smoke detectors and carbon monoxide alarms in your house work,” said FDNY Chief of Department Edward Kilduff. “Go home, talk to your mother and your father, your brother and your sister, and make sure the smoke detector works.”
