Fire drills can be fun family events. Hold drills at different times of the day and night, and in the middle of different daily routines. Practice using the second way out of bedrooms and other rooms when it is safe to do so. Be sure that they open in an emergency without special effort or tools. Have an outside meeting place that will work in winter as well as other seasons.
Smoke alarms are inexpensive effective devices that alert people when fire occurs.
Install some in your home and test them regularly to make sure they work.
