Smoke Detectors

Why focus on smoke/CO2 alarms four years in a row? Because NFPA’s survey data shows that the public has many misconceptions about smoke/CO2 alarms, which may put them at increased risk in the event of a home fire and/or gas leak. For example, only a small percentage of people know how old their alarms are, or how often they need to be replaced.

As a result of those and related findings, we’re addressing smoke/CO2 alarm replacement this year with a focus on these key messages:

  • Test smoke detectors.
  • Change the batteries at the same time you change your clock for daylight saving.
  • Make sure you know how old all the smoke/CO2 alarms are in your home.  These alarms should be replaced every 10 years.
  • To find out how old a smoke/CO2 alarm is, look at the date of manufacture on the back of the alarm; the alarm should be replaced 10 years from that date (refer to image below).
