Most of us don’t.
You may already be aware you should test the smoke alarms in your house each month. Did you know you should also replace those alarms every 10 years?
Most homeowners, according to the National Fire Protection Association (NFPA), are unaware of this guideline—in fact, nine out of 10 in a recent survey by the organization did not know alarms expire. What’s more: one in five has an alarm in their home that is more than 10 years old, and an identical proportion does not know how old their alarms are at all.
“While the public generally knows that smoke alarms play an important role in home fire safety, some smoke alarm messages are not as well understood,” said Lorraine Carli, vice president of Outreach and Advocacy for NFPA, in a statement. “Not knowing how often smoke alarms need to be replaced—or that they even have an expiration date—are among them.”
Homeowners should inspect their smoke alarms for the “date of manufacture,” which is generally on the back or side of the device—this date indicates age, according to NFPA. The date of manufacture is not the same as the date of purchase or date of installation.
“Working smoke alarms reduce the risk of dying in a home fire in half,” Carli added. “That’s why it’s so important to make sure they’re working properly.”
Aside from testing alarms on a monthly basis, Carli and NFPA recommend replacing the batteries as soon as the warning chirp sounds.
