Bombay
On February 27, 1986, 62 people, including 12 women and 11 children, were hospitalized after inhaling chloride gas that leaked from the Bombay Municipal Corporation's chlorination plant in Kishan Nagar, Bombay. Sixty were discharged after treatment, while two remained under observation. The leak occurred at 3 a.m. when the plant's automatic diaphragm gave way due to excessive pressure.
