A great free prep is planning. Get your family together and make a fire plan. Make a map of the house. Show fire extinguishers, exits, and meeting place. Also a tornado plan, flood plan, hurricane etc… Call down lists are also good to have. A good family call down list is great in an emergency. Here is how they work. At the top are family leaders, Grandparents, parents or whoever. But someone has to be the very top. They have a list of everyone in the entire chart. The leader is responsible for calling the next group down. So say Grandparents call all their kids. Then Those kids call all their kids and so on down the list. When it gets to the bottom of the list everyone (except the lowest level) calls back up the list and gives a report on who they talked to and who they didnt. When it gets back to the top you should have everyone in your family either accounted for or you know exactly who to start searching for. This doesnt have to be just a family either. It could be a whole neighborhood or community. Just as long as its a hierarchy that everyone knows and respects. And doing a Call Down Drill like a fire drill every once in a while is good practice and doesnt cost anything either.
