DefCon 5
1) Have a “Family Plan” of what to do and where and how to meet in the event of an incident. Insure all family members are thoroughly briefed.
2) Ensure that basic supplies are kept at home for a minimum of 72 hours (3 days) sustenance/maintenance.
3) Know where the other family members are, when not at home.
4)
4) Make sure everyone knows where everything is.
5) Make sure everyone knows how to use everything (camp stoves, water purification, sanitation procedures, etc...)
6) Make sure everyone CAN use the stuff (is wife/children strong enough to yank-start a generator or lift/move a filled aquatainer).
