Change Your Clock, Change Your Smoke Alarm Battery

The San Francisco Fire Department would like to remind you that the day when you change your clocks for daylight savings time is the perfect opportunity to change the batteries in your smoke alarms.Time to Change Your Smoke Alarm Battery

When smoke alarms fail, it is usually because batteries are missing, disconnected or dead.  According to the National Fire Protection Association, the households with non-working smoke alarms now outnumber those with no smoke alarms.  Smoke alarms that are properly installed and MAINTAINED play a vital role in reducing fire deaths and injuries.  As most fatal fires occur at night, by taking the time to replace the batteries in your smoke alarms, you can sleep better knowing that you've provided one of the best ways to alert those in your household should a fire occur.

Remember, almost every day a smoke alarm saves someone's life.

Smoke Alarm Tips:

  • Test smoke alarms once a month
  • Replace batteries in all smoke alarms twice a year (when you change your clocks for daylight savings time)
  • Never remove the batteries from smoke alarms, not even temporarily
  • Regularly vacuum or dust smoke alarms to keep them working properly
  • Replace smoke alarms every 10 years
  • Don't paint over smoke alarms
  • Practice family fire drills so everyone knows what to do if the smoke alarm goes off

If you have any questions regarding the installation and maintenance of smoke alarms, or if you have any other questions about how to protect yourself and your household in the event of a fire, please feel free to contact the Bureau of Fire Prevention.
