Batteries should be changed at least once a year and tested monthly to make sure they are working. Show students where the batteries go in a smoke alarm. Press the test button to demonstrate it is working properly. Also, remind students that alarms need to be kept clean from dust. This can be done by running a vacuum cleaner attachment over and around them.
Smoke alarms are very easy to install and take care of.
To help teach your children about smoke alarms, ask them to help you install and maintain them. Install smoke alarms on every level of your home, including the basement. Many fatal fires begin late at night or in the early morning. For extra safety, install smoke alarms both inside and outside the sleeping area. Also, smoke alarms should be installed on the ceiling or 6 to 8 inches below the ceiling on side walls.
