Every Smoke Alarm Has an Expiration Date: What’s Yours?

Does your home have a smoke alarm? According to the National Fire Protection Association (NFPA), the answer is likely yes: NFPA research shows that most American homes have at least one.

But do you know how old your smoke alarms are? If you’re like most people, you’re probably not so sure.

A recent survey conducted by NFPA revealed that only a small percentage of people know how old their smoke alarms are, or how often they need to be replaced. That lack of awareness is a concern for NFPA, along with fire departments throughout the country, because smoke alarms don’t last forever.

“Time and again, I’ve seen the life-saving impact smoke alarms can have in a home fire, but I’ve also seen the tragedy that can result when smoke alarms aren’t working properly,” said Kelley Klope, Asheville Fire Department Public Information Officer.

As the official sponsor of Fire Prevention Week for more than 90 years, NFPA is promoting this year’s Fire Prevention Week campaign — “Don’t Wait – Check the Date! Replace Smoke Alarms Every 10 Years” — to better educate the public about the critical importance of knowing how old their smoke alarms are and replacing them once they’re 10 years old. Fire Prevention Week is October 9-15.

Check your smoke alarm

To find out how old your smoke alarm is and 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 (not the date of purchase). You should also test smoke alarms monthly, and batteries should be replaced twice a year when you change your clocks for daylight savings time.
