Emergency experts recommend that you prepare for emergencies using an "All-hazards approach". The preparedness steps you take, for any type of emergency, will go a long way in minimizing the negative impacts of almost any disaster situation that you may encounter.
Disasters disrupt hundreds of thousands of lives every year. Each disaster has lasting effects, both to people and property. If a disaster occurs in your community, local government and disaster-relief organizations will try to help you, but you need to be ready as well. Local responders may not be able to reach you immediately, or they may need to focus their efforts elsewhere. You should know how to respond to severe weather or any disaster that could occur in your area - hurricanes, extreme cold, flooding, or terrorism.
You should also be ready to be self-sufficient for several days. This may mean providing for your own shelter, first aid, food, water, and sanitation.
The most vital key to successfully managing any type of disaster, natural or manmade, is to be properly prepared.
