First, if you haven't done so already, formulate family emergency plans for possible emergencies- fire, flood, storm, burglary/home invasion or whatever.
Once your plans are thoroughly reviewed, then it's time to practice them on a regular schedule. Plans and expectations should realistically reflect the maturity level and confidence level of your children. I'd think at this point all of them would depend on the adults in the family for help and guidance in the event of emergencies, but knowing what to expect will help them cope in the event of the real thing.
