The speed of fire is phenomenal. This is all the time you have to wake up and get out. That is why an escape plan is imperative. Create at least two different escape routes for each family member and practice them with the entire family. When you practice your escape, close doors behind you.
Closed doors slow the spread of fire.
Also, you should crouch down low to avoid breathing in smoke. Make sure your children understand that a smoke detector signals a home fire and that they recognize its alarm. Have a designated meeting place outside and make sure all members of your family know the location. Under no circumstance should anyone go back into your home during a fire. Call the fire department from a neighbors house.
