The end of daylight saving time at 2 a.m. on Sunday, Nov. 5 is a perfect reminder to move clocks back an hour AND also test each of your smoke alarms and carbon monoxide (CO) detectors, reminds Ohio State Fire Marshal Kevin Reardon.

“We see the life-saving impact properly functioning smoke alarms can have when the worst happens,” Reardon said. “Working smoke alarms save lives, cutting your risk of dying in a house fire in half.”

Along with making sure all smoke alarms have a fresh set of batteries, checking the expiration date is crucial in early fire detection. To find out how old a smoke alarm is, as well as its expiration date, simply look on the back of the alarm where the date of manufacture is marked.

The smoke alarm should be replaced 10 years from that date. Any alarms with a manufacture date of 2013 or earlier should be replaced.
