Michael Petruccelli asks; What can you do to prepare your family in the event of a home fire? (part 4)

Michael Petruccelli says;  Install and test smoke (fire) alarms. Demonstrate the sound of the smoke (fire) alarm in your house by pressing the test button, so that everyone has heard it ahead of time, especially small children. At a minimum, alarms should be installed on each level of the home and in each bedroom. Alarms should be tested monthly, replacing batteries semi-annually.
