No proper study had been made of the dangers of a leak either due to negligence or deliberately. There had been no contingency planning to deal with the resulting situation.
It is to the credit of the authorities of the Madhya Pradesh government and the Union government led by Rajiv Gandhi, that they rose to the occasion and did whatever they could to save lives at tremendous risk to themselves. Despite their praise-worthy efforts, over 3500 people died--as many as during the 9/11 terrorist strikes in the US.
In many seminars that I have attended since 9/11 on the dangers of an act of mass casualty terrorism using a chemical weapon, there were references to the Bhopal disaster as a forewarning of what could happen if terrorists managed to get hold of a deadly chemical weapon and use it. Many of those who made the reference, at the same time, expressed their surprise and disappointment over the fact that the Indian authorities had not documented the details of what happened in Bhopal in 1984, how the situation was dealt with by the authorities, what kind of difficulties they faced and how they got over them.
In fact, according to security experts, no proper case study of the Bhopal gas disaster has been made to draw lessons for future contingency planning to deal with similar disasters. If this is true, this does not speak well of us and underlines once again our casual attitude in such matters.
Before the officials of Bhopal who dealt with the disaster pass away, their account of the disaster should be documented and a thorough case study done.
It goes to the credit of Rajiv Gandhi that he realized the importance of contingency planning to deal with similar disasters in future and set up a special cell in the Ministry of Home Affairs for this purpose. Contingency planning for disaster management started receiving the attention it deserved only after 9/11.
