The Bhopal Disaster took place in the early hours of December 3, 1984, in the heart of the city of Bhopal in Madhya Pradesh. A Union Carbide subsidiary pesticide plant released 40 tonnes of methyl isocyanate (MIC) gas, immediately killing nearly 3,000 people and ultimately causing at least 15,000 to 22,000 total deaths.

Bhopal is frequently cited as one of the world's worst industrial disasters.
In the early hours of December 3, 1984, a holding tank with 43 tonnes of stored MIC overheated and released toxic heavier than air MIC gas mixture, which rolled along the ground through the surrounding streets. The transportation system in the city collapsed and many people were trampled trying to escape. According to the Bhopal Medical Appeal, around 500,000 people were exposed. Approximately 20,000, to this date, are believed to have died as a result; on average, roughly one person dies every day from the effects. Over 120,000 continue to suffer from the effects of the disaster, such as breathing difficulties, cancer, serious birth-defects, blindness, gynaecological complications and other related problems.
The majority of deaths and serious injuries were related to pulmonary edema, but the gas caused a wide variety of other ailments. Signs and symptoms of methyl isocyanate exposure normally include coughing, dyspnea, chest pain, lacrimation, eyelid edema, and unconsciousness. These effects might progress over the next 24 to 72 hours to include acute lung injury, cardiac arrest, and death. Because of the hypothesized reactions that took place within the storage tank and in the surrounding atmosphere, it is thought that apart from MIC, phosgene, and hydrogen cyanide along with other poisonous gases all played a significant role in this disaster. The Union Carbide India, Limited (UCIL) plant was established in 1969 and had expanded to produce carbaryl in 1979; MIC is an intermediate in carbaryl manufacture.
The chemical accident was caused by the introduction of water into methyl isocyanide holding tank E610, due to slip-blind water isolation plates being excluded from an adjacent tank's maintenance procedure. The resulting reaction generated a major increase in the temperature of liquid inside the tank (to over 200°C). The MIC holding tank then gave off a large volume of toxic gas, forcing the emergency release of pressure.
