I remember talking to a coworker who had lived in California in the "fire" zone. A fire came up quickly and he was not prepared. He had no time to gather up his important papers all over the house, think about what else he should grab (almost forgot the dog). After that he started putting important things together in one place in a carry bag. He added things when he realized that he would need it. The most important thing his family rehearsed, was where they would gather in one spot (with a backup) and count heads so everyone would get into the car. They also did the same if they were split up for any reason have a central gathering place.
People at work and school have fire drills to get people to know and remember automatically where the fire doors are (also an alternative if that is blocked by fire), where to go outside the building far enough away, have a particular place their bureau should gather and have a head count. The fire department would time the employees and then have reminders for things that should be adjusted.
Why not at home?
