Monthly Preparedness TipFamily
Emergency Plan


It's important to have a family emergency plan in place before disaster strikes. Remember that the objective of a family emergency plan is to be prepared to be self-sufficient for a minimum of 72 hours. An emergency can happen anytime and anywhere. Practice often helps people feel less disoriented and better organized in case of a disaster - even in the middle of the night or the middle of winter.
