An introduction to Man Made Disasters-- their Causes, Consequences & Mitigation Measures

Published in: Education

Manmade Disasters

  1. 1.  Disaster is a certain cataclysmic event that seriously disrupts the functioning of society and causes human, material, environmental and economic loss that exceeds the community or society’s ability to cope using its own resources.
  2. 2.  Natural Disasters - A natural disaster is an event that is caused by a natural hazard and leads to human, material, economic and environmental losses, which exceed the ability of those affected to cope; examples include floods, volcanic eruptions, earthquakes, tsunamis and other geological processes.  Man-made Disasters - A serious disruption of normal life triggered by a human-induced hazard causing environmental, economic or life loss.
  3. 3.  Nuclear Disaster  Chemical Disaster  Biological Disaster  Technological Disaster
  4. 4.  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."
  5. 5.  Nuclear weapons are thus, far more destructive and harmful to the society than any other weapon.  Many countries in the world have developed nuclear energy. ** The developed countries reiterate that nuclear energy will be used only for PEACEFUL PURPOSES.
  6. 6.  Radiation is released into the environment and people get hurt.  Nuclear radiation keeps on showing its effect for a considerable period of time even after its explosion, and those who survive become mental and physical wrecks due to the impact of nuclear radiation.  Two of the most famous nuclear accidents occurred at the Three Mile Island reactor 2 in the United States and the Chernobyl reactor 4 in the former Soviet Union
  7. 7.  We should keep ourselves informed about the government plants and should act in accordance with official communication.  Nuclear activity may affect our health and cause nausea, giddiness etc., and for that medical help should be available .
  8. 8.  Biological disasters define the devastating effects that may be caused by an enormous spread of a certain kind of living organism - that may be the spread of a disease, a virus, an epidemics, but also just a sudden growth of the population of a certain kind of plants or animals, e.g. Ebola and swine flu.
  9. 9.  Biological disaster spreads through the organism that is developed in the form of BACTERIA or MICROBES. Biological agent spread fast in the environment and then makes an attack on the human beings. The people inhale these microbes. When these microbes find themselves a host body, they start affecting the immune systems of the body. Microbes’ also enter human body through open wounds or cuts.
  10. 10.  The attack of the microbes is generally slow but once they are spread in the body, it becomes difficult to control them.  Sometimes it takes the life of the affected persons.  Many a time, it becomes difficult to diagnose the illness caused by these microbes and it proves to be fatal.
  11. 11.  Whenever we learn or hear about danger of communicable diseases through official announcements on radio or TV, then we can take adequate preventive and protective measures.  We should quite often try to help in taking this type of noble cause and solve the problem of affected people, or try to create fund for this uncertain event.
  12. 12.  By their nature, chemical disaster may be defined as the manufacture, storage, and transport of chemicals which may lead to the accidents waiting to happen. Chemicals can be corrosive, toxic, and they may react, often explosively.
  13. 13.  Chemical weapons are the main cause of such disasters.  Sometimes handling of hazardous chemicals in an irresponsible way can cause chemical disasters.  Chemical disasters may also be caused by industrial accidents.
  14. 14.  The impacts of chemical accidents can be deadly, for both human beings & environment.  Chemical weapons are also weapons of mass destruction.  Sometimes handling of hazardous chemicals in an irresponsible way can cause much destruction.  The poisonous gases spread in the atmosphere and the people who inhale the same air face dangerous consequences.
  15. 15.  Those industries, which use hazardous chemicals or produce such chemicals, should have contingency action plan to help people if such a disaster takes place.  Such industries should have timely warning systems so that people can immediately take safety measures such as locking their houses and taking the family and animals away to a safe place.  Stringent safety measures and checkups in the factory and critical analysis of the working condition of the factory will help to take timely measures to check any disaster.
  16. 16.  Gas Leak on December 3, 1984 – MIC (Methyl Iso Cyanate)  8000 people died, 50,000 injured  Gas leaked from a Union Carbide Plant at night People fled from the poison gas in the middle of the night Main effect: Pulmonary Edema, skin and eye damage (total blindness) Secondary effect: Bronchitis, Bronchial pneumonia A Bhopal Victim
  17. 17.  A technological disaster is an event caused by a malfunction of a technological structure and/or some human error in controlling or handling the technology.  The effects of a disaster on families and individuals may be long lasting and can endure for years. However, symptoms may appear gradually, and impacts may not be seen immediately.  All types of disasters are challenging, but technological disasters tend to be even more difficult.
  18. 18.  In addition to the Deepwater Horizon/BP oil spill, radiation leaks are another example of a technological disaster, such as in the recent case of the Fukushima Daiichi Nuclear Power Station in Japan and previous accidents at Chernobyl and Three Mile Island.  Fires or explosions—such as the Station Nightclub fire in Warwick, Rhode Island, that was caused by a pyrotechnics malfunction—are also examples of technological disasters.  Chemical spills from trucks or trains would also be considered technological disasters. These examples all have differing characteristics and effects on the environment and residents of the immediate disaster area.
  19. 19.  Technological disasters are stressful, especially because they are unpredictable. Individuals, families, and communities are affected. Some of the results include income loss, loss of job security, uncertainty about the future, family conflict, and stress.  In particular, post-traumatic stress disorder (PTSD), depression, and anxiety symptoms were common responses to a disaster similar to the Deepwater Horizon/BP oil spill, the Exxon Valdez oil spill. Impacts may persist over time for some individuals, while others show resilience earlier.
  20. 20.  Maintain routine as much as possible.  Reduce exposure to media covering the event.  Stay healthy and find healthy ways to reduce stress, such as doing things outside, getting exercise, and doing stress reduction exercises.  Seek accurate sources of information to better understand the situation.  Talk to someone you trust.  Keep a positive perspective—you can get through this!  Seek professional help if you are feeling depressed, anxious, or have trouble controlling your emotions.
