A disaster is a calamitous event, especially one occurring suddenly and causing great loss of life, damage, or hardship. Can we prevent disasters? No, but we can prepare for them. Emergency disasters deal with survival, which is one of the primary needs of human beings. It includes the need for water, food, rest, clothing, shelter, and health. When preparing for eventual disasters, we can take care of at least four physical needs. These include protection, location, water, and food. Other factors can affect our chance of overcoming an emergency though. Our psychology is one of them.
