It produced the pesticide carbaryl trademark Sevin. Methyl isocyanate MICan intermediate in carbaryl manufacture, was also used.
Bhopal gas tradegy was known was that the methylisocyanate MIC unit had been shut down six weeks before the incident, and the MIC storage Tank -- from which the gas was released -- had been isolated at that time.
The UCC team was only permitted to take samples of the residue in Tank and, after several months of extensive analyses, issued a report in March A committee of experts, working on behalf of the Indian government, conducted its own investigation and reached the same conclusion.
The incident occurred despite the fact that the system had been designed and operated to keep out even trace amounts of water and that no water had ever entered any of the tanks during the five years the plant had been in operation. Cause Finally Determined For more than a year, the CBI prohibited interviews with plant employees and denied meaningful access to plant records.
However, in Decembera U. Moreover, the GOI could no longer restrict access to plant employees while it was before a U. Shortly after the gas release, UCC launched an aggressive effort to identify the cause. With access to employees and plant records, UCC investigators conducted more than 70 interviews in India and examined some 70, pages of plant records and documentation that the Indian government had reluctantly released.
UCC's follow-up investigation confirmed its initial conclusion: This caused a chemical reaction that forced the pressure release valve to open and allowed the gas to leak.
Some two and a half years after the tragedy, UCC filed a lengthy court document in India detailing the findings of its scientific and legal investigations: Click here to view the Jackson Browning Report. All of this was supported by hard evidence set forth in the presentation made by Ashok S.

Investigations suggest that only an employee with the appropriate skills and knowledge of the site could have tampered with the tank. An independent investigation by the engineering consulting firm Arthur D. Were the valves faulty on the MIC tanks at the plant?
In fact, documented evidence gathered after the incident showed that the valve near to the plant's water-washing operation was closed and leak-tight. Furthermore, process safety systems -- in place and operational -- would have prevented water from entering the tank by accident.
Based on several investigations, the safety systems in place could not have prevented a chemical reaction of this magnitude from causing a leak.Thirty years ago, on the night of December 2, , an accident at the Union Carbide pesticide plant in Bhopal, India, released at least 30 tons of a highly toxic gas resulting in a death toll.
Cause of the Bhopal Tragedy Print. Union Carbide's Investigation A Union Carbide Corporation (UCC) investigation team arrived in Bhopal within days of the incident, but could not begin its investigation because the Indian Central Bureau of Investigation (CBI) had taken control of and sealed the plant; seized control of the plant’s records; and prohibited interviews of plant employees on duty.
