Why do British people keep comparing the BP disaster to Bhopal?Answer
It is completely different. Bhopal happened 25 years ago. Indian executives, not Americans, were sentenced for the crimes committed there. BRITISH CEO Hayward of BRITISH petroleum needs to be sentenced under the American judicial system for the massive ecological damage he has brought upon this nation.
British people keep comparing the BP disaster to Bhopal because they are both ecological disasters that affected people. Lives were lost (in the BP disaster, the oil spill resulted from an explosion) and they affected people in many ways.
The plant was eventually shut down, but the land remains a toxic site, and increasing amounts of poisonous chemicals are bing dumped there. Basically the whole thing was swept under the rug. Union Carbide got away with murder literally, and the government of India is powerless to do anything about anything. Here's a link:
Why is the Bhopal chemical plant disaster happened?Answer
In the evening of December 2nd~3rd, 1984, a Union Carbide plant in Bhopal has just exploded leaking 27 tons of methyl isocyanate and other chemicals from the plant. There were the six safety systems designed to prevent such a leak were operational, but none of them worked. Many people were trying to escape, but 25,000 people are died.
WHY IS IT HAPPENED ?
"Summary of background and causes
The UCIL factory was built in 1969 to produce the pesticide Sevin (UCC's brand name for carbaryl) using methyl isocyanate (MIC) as an intermediate. A MIC production plant was added in 1979.
During the night of December 2–3, 1984, water entered a tank containing 42 tons of MIC. The resulting exothermic reaction increased the temperature inside the tank to over 200 °C (392 °F) and raised the pressure. The tank vented releasing toxic gases into the atmosphere. The gases were blown by northwesterly winds over Bhopal.
Theories of how the water entered the tank differ. At the time, workers were cleaning out a clogged pipe with water about 400 feet from the tank. The operators assumed that owing to bad maintenance and leaking valves, it was possible for the water to leak into the tank. However, this water entry route could not be reproduced. UCC also maintains that this route was not possible, but instead alleges water was introduced directly into the tank as an act of sabotage by a disgruntled worker via a connection to a missing pressure gauge on the top of the tank. Early the next morning, a UCIL manager asked the instrument engineer to replace the gauge. UCIL's investigation team found no evidence of the necessary connection; however, the investigation was totally controlled by the government denying UCC investigators access to the tank or interviews with the operators. The 1985 reports give a picture of what led to the disaster and how it developed, although they differ in details.
Factors leading to the magnitude of the gas leak include:
* Storing MIC in large tanks and filling beyond recommended levels
* Poor maintenance after the plant ceased MIC production at the end of 1984
* Failure of several safety systems (due to poor maintenance)
* Safety systems being switched off to save money—including the MIC tank refrigeration system which could have mitigated the disaster severity
The problem was made worse by the mushrooming of slums in the vicinity of the plant, non-existent catastrophe plans, and shortcomings in health care and socio-economic rehabilitation."
