This chapter introduces the fundamental ideas behind disaster planning and mitigation, the universal tasks that apply to all disaster responses, and the essential elements of a disaster preparedness strategy.
The numerous sorts of disasters are defined along with a classification scheme based on their onset, duration, effect (immediate aftermath), common and distinctive aspects, and reaction phase. The disaster nursing timeline idea is presented as an organizational framework for strategic planning. Preparedness, mitigation, response, and recovery are the four main areas of focus in emergency and disaster preparedness. Evaluation is a fifth area of focus that is suggested.
