At the time, it was called the worst industrial accident in history. On December 3,about 45 tons of the dangerous gas methyl isocyanate escaped from an insecticide plant that was owned by the Indian subsidiary of the American firm Union Carbide Corporation. The gas drifted over the densely populated neighbourhoods around the plant, killing thousands of people immediately and creating a panic as tens of thousands of others attempted to flee Bhopal.
This "route" differed from the MIC-free routes used elsewhere, in which the same raw materials were combined in a different manufacturing order, with phosgene first reacting with naphthol to form a chloroformate ester, which was then reacted with methylamine.
In the early s, the demand for pesticides had fallen, but production continued, leading to build-up of stores of unused MIC where that method was used. In a panic, he removed his gas mask and inhaled a large amount of toxic phosgene gas, leading to his death just 72 hours later. None of the workers had been ordered to The bhopal disaster of 1984 protective masks.
One month later, in Februaryan MIC leak affected 18 workers. In Augusta chemical engineer came into contact with liquid MIC, resulting in burns over 30 percent of his body. Later that same year, in Octoberthere was another MIC leak. In attempting to stop the leak, the MIC supervisor suffered severe chemical burns and two other workers were severely exposed to the gases.
During andthere were leaks of MIC, chlorine, monomethylamine, phosgene, and carbon tetrachloridesometimes in combination. E, E, and E In the months leading up to the December leak, liquid MIC production was in progress and being used to fill these tanks.
Each tank was pressurized with inert nitrogen gas. This pressurization allowed liquid MIC to be pumped out of each tank as needed, and also kept impurities out of the tanks. It meant that the liquid MIC contained within could not be pumped out.
At the time of this failure, tank E contained 42 tons of liquid MIC. An attempt to re-establish pressure in tank E on 1 December failed, so the 42 tons of liquid MIC contained within still could not be pumped out of it.
During decontamination of the plant, tank was removed from its foundation and left aside. In addition, several vent gas scrubbers had been out of service as well as the steam boiler, intended to clean the pipes.
Two different senior refinery employees assumed the reading was instrumentation malfunction. One was found by The decision was made to address the problem after a The incident was discussed by MIC area employees during the break.
One employee witnessed a concrete slab above tank E crack as the emergency relief valve burst open, and pressure in the tank continued to increase to 55 psi The two siren systems had been decoupled from one another inso that it was possible to leave the factory warning siren on while turning off the public one, and this is exactly what was done: Finally, they received an updated report that it was "MIC" rather than "methyl isocyanate"which hospital staff had never heard of, had no antidote for, and received no immediate information about.
People awakened by these symptoms fled away from the plant. Those who ran inhaled more than those who had a vehicle to ride. Owing to their height, children and other people of shorter stature inhaled higher concentrations, as methyl isocyanate gas is approximately twice as dense as air and hence in an open environment has a tendency to fall toward the ground.
Primary causes of deaths were chokingreflexogenic circulatory collapse and pulmonary oedema. Findings during autopsies revealed changes not only in the lungs but also cerebral oedematubular necrosis of the kidneys, fatty degeneration of the liver and necrotising enteritis.
The gas cloud, composed mainly of materials denser than air, stayed close to the ground and spread in the southeasterly direction affecting the nearby communities. Upon arrival Anderson was placed under house arrest and urged by the Indian government to leave the country within 24 hours.
Union Carbide organized a team of international medical experts, as well as supplies and equipment, to work with the local Bhopal medical community, and the UCC technical team began assessing the cause of the gas leak. The health care system immediately became overloaded.
In the severely affected areas, nearly 70 percent were under-qualified doctors.
Medical staff were unprepared for the thousands of casualties.of the Bhopal disaster, the article outlines lessons that need to be learned WORDING OKAY?.
The Shock and Awe It was just past midnight of December 2, Nearly 30 of the 42 metric tons of MIC stored in Tank of the UCIL pesticide plant escaped with consid-erable velocity within a . The Bhopal disaster, also referred to as the Bhopal gas tragedy, was a gas leak incident on the night of 2–3 December at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal, Madhya Pradesh, India.
It was considered as of to be the world's worst industrial disaster.
