Pick a neighbor's house, a tree, or a telephone pole. Make sure you pick a place far enough away from your home so that no one is harmed by smoke or fire. Call the fire department to report the fire once you get outside. Practice your Great Escape twice a year. That way, everyone will know how to escape in case of an emergency.
Fire is very dangerous.
Firefighters are trained and equipped to go inside a burning building - get outside safely and let them do their jobs. Your health and safety, and that of your family, is most important.
