Working smoke alarms are one of the simplest and most effective ways to protect your family from a fire. The Chatham County Fire Department encourages residents to test their smoke alarms every month to ensure they are functioning properly and to clean them regularly by gently removing dust and debris that can interfere with their operation. Make it a habit to check your alarms on the same day each month, and replace the batteries at least once a year or whenever the alarm begins to chirp, signaling a low battery. Smoke alarms should be installed on every level of your home, inside each bedroom, and outside sleeping areas. A properly maintained smoke alarm provides valuable early warning, giving you and your family the time needed to safely escape in the event of a fire. Taking just a few minutes each month to test your smoke alarms can make all the difference when every second counts.
