Depending on your circumstances and the nature of the emergency, the first important decision is whether you stay where you are or evacuate. You should understand and plan for both possibilities. Use common sense and available information, including what you are learning here, to determine if there is an immediate danger. In any emergency, local authorities may or may not immediately be able to provide information on what is happening and what you should do. However, you should watch TV, listen to the radio or check the Internet often for information or official instruction as it becomes available.
