There is a need for the improvements in safety equipment manual to automatic. This incident is considered the worst industrial disaster in the world. The plant had a capacity of 5, metric tons per year of MIC. The reserve tank was full of MIC. Figure 8 Flow sheet of the mitigation process For me as a chemical engineer the above mitigation process is a wonderful one. It happened when about tons of extremely toxic MIC gas released to the atmosphere.
Bhopal gas tragedy – US court rejects case against Union Carbide. Government not ensuring compliance with regulations 6. All of them gave warnings about bad management, poor maintenance, poor training and careless about safety regulations.

At the time of the disaster only six of the twelve operators were still working and the number of the supervisors was reduced to the half. The water was supposed to be drained through drainage nozzles. In addition, trageyd and graduating chemical engineers became closer to the process safety and environmental issues through the educational development and scientific research.
This alarm was switched off after 5 minutes. Other eighth employee died in jail before the judgment. In closed system these reactions could increase the pressure in great manner. The only thing done for most of those poor people was drops in their eye. Other references stated that among the people, who were exposed to gas, people died, injured, continue to suffer of bad health effects.
The Bhopal Gas Tragedy
If water comes in contact with MIC a run-away reaction starts which increases the reaction temperature, as a result trxgedy reaction rate increases more and more. Flare tower was out of service for five months before the disaster because a length of piping was corroded and was not replaced.
Then bone dry, high purity nitrogen was used at the Bhopal plant to reduce the risk of contamination, especially from trace amounts of water. At midnight the MIC started to leak from the safety valves of the tank.
Other leaks happened and It resulted in great changes in the US regulations. UCC and Indian government continued this claim till In summary, the accident was waiting to happen, and was given a chance to happen The company and the operators were careless about safety of the society and workers.
