The escape of about 40 tonnes of methyl isocyanate (MIC) – a highly toxic chemical – from a storage tank on the premises of the pesticide plant of Union Carbide India Limited (UCIL) in Bhopal – the capital of the State of Madhya Pradesh – on the night of 02/03 December 1984, 31 one years ago today, resulted in a horrendous disaster. Due to criminal negligence and utter callousness on the part of the plant management in taking adequate safety precautions, water and other impurities – that cause MIC to react violently – entered one of the MIC storage tanks resulting in exothermic reactions and forcing MIC and its reaction products to escape in the form of froth and lethal gases.
