The Bhopal gas tragedy was one of the worst industrial disasters, killing 20,000 people. In 1984, water leaked into a tank containing 42 tons of methyl isocyanate (MIC) at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal, leading to a toxic gas leak. Factors such as negligence, defective equipment, unmaintained safety systems, and storing chemicals beyond capacity contributed to the massive casualties and injuries. The Indian government was criticized for its handling of the aftermath including suppressing data and allowing the CEO to leave India without charges. Survivors continue to suffer health issues decades later.
