Bhopal disaster

3 December 1984

The Bhopal disaster was a catastrophic leak of toxic gas at a pesticide plant owned by the Indian subsidiary of the American company Union Carbide, in the city of Bhopal in central India. Water entered a tank of methyl isocyanate and set off a reaction, and the gas spread through densely populated neighbourhoods near the plant while people slept. Thousands died within days, and many more suffered from lasting illness, with estimates of the full toll varying widely. Investigations pointed to poor maintenance, neglected safety systems and cost cutting. The disaster led to long legal battles over compensation, and survivors and campaigners say the people affected and the contaminated site were never adequately dealt with.
