2. Introduction Man-made disasters have an element of human intent, negligence, or error involving a failure of a man-made system, as opposed to natural disasters resulting from natural hazards. Such man-made disasters are crime, arson, civil disorder, terrorism, war, biological/chemical threat, cyber-attacks, etc.

3. Nuclear Disaster A nuclear and radiation accident is defined by the International Atomic Energy Agency as "an event that has led to significant consequences to people, the environment or the facility. Examples include lethal effects to individuals, large radioactivity release to the environment, or reactor core melt."The prime example of a "major nuclear accident" is one in which a reactor core is damaged and significant amounts of radiation are released

4. Biological Disasters Biological disasters are natural scenarios involving disease, disability or death on a large scale among humans, animals and plants due to micro-organisms like bacteria, or virus or toxins. Biological disasters may be in the form of:- Epidemic affecting a disproportionately large number of individuals within a population, community, or region at the same time, examples being Cholera, Plague; or, Pandemic is an epidemic that spreads across a large region, that is, a continent, or even worldwide of existing, emerging or reemerging diseases and pestilences, example being Influenza H1N1 (Swine Flu).

5. Chemical Disaster A chemical disaster is the unintentional refuse of one or more hazardous substances which could harm human health or the environment. Chemical hazards are systems where chemical accidents could occur under certain circumstances. Such events include fires, explosions, leakages or releases of toxic or hazardous materials that can cause people illness, injury, disability or death.

6. Fire Accidents Fires are events in which something burns. Generally, they are destructive, killing many people. More people die in fires than in cyclones, earthquakes, floods, and other natural catastrophes combined. Throughout cities, there are fires breaking out in homes, jhuggis, factories, warehouses, and other buildings. Fires are a significant threat to forests and wildlife because they spread rapidly and cause tremendous damage. Fire can transmit to a large area. Many people could succumb to burns and asphyxiation. This contamination may also harm plants, animals, and soil, affecting crops, water, and soil fertility.
