The Kingsport Fire Department (KFD) urges all residents to know how old their smoke alarms are and to replace them every 10 years.

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 the Kingsport Fire Department and 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,” says Barry Brickey, public education officer of the Kingsport Fire Department. “It’s why we’re making a concerted effort to educate residents about the overall importance of smoke alarms, and that they do have a life limit.”

NFPA 72, National Fire Alarm Code®, requires smoke alarms be replaced at least every 10 years, but because the public is generally unaware of this requirement, many homes have smoke alarms past their expiration date, putting people at increased risk.

In Tennessee, landlords are required to provide working smoke alarms for their rental apartments and homes. If you are a landlord, replace the alarms in your properties every 10 years to protect your renters and your property.

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). The KFD also says smoke alarms should be tested monthly, and that batteries should be replaced once a year or when they begin to chirp, signaling that they’re running low.
Fire Prevention Week’s theme this year is ‘Don’t Wait: Check the Date! Replace Smoke Alarms Every 10 Years.’ The KFD encourages residents and landlords to check their alarms and replace any over 10 years old. Fire prevention is so important here in Kingsport that we stretch it out the entire month of October!

The Kingsport Fire Department is hosting public events, station tours, and school visits in support of Fire Prevention Week/Month.
