What If World War III Happened Tomorrow If a nuclear blast is on the cards then it could take place without lengthy warning. Therefore if you think an attack is likely it is best to be prepared. Experts recommend you follow the guidelines below to protect yourself, your family and your home - if you believe an attack is imminent. Build an Emergency Supply Kit, which includes items like non-perishable food, water, a battery-powered or hand-crank radio, extra flashlights and batteries. You may want to prepare a kit for your workplace and a portable kit to keep in your car in case you are told to evacuate. Make a Family Emergency Plan. Your family may not be together when disaster strikes, so it is important to know how you will contact one another, how you will get back together and what you will do in case of an emergency. Find out from officials if any public buildings in your community have been designated as fallout shelters. If none have been designated, make your own list of potential shelters. These places would include basements or the windowless central area of middle floors in high-rise buildings.
