India's Chemical Industry
The Bhopal Gas Disaster
How a gas leak at Union Carbide's pesticide plant in Bhopal in December 1984 killed thousands, the legal and compensation battles, and its lessons for industrial safety and liability.
On the night of 2-3 December 1984, methyl isocyanate gas leaked from Union Carbide India Limited’s pesticide plant in Bhopal.
The disaster
- Thousands died within days; official estimates rose over years, with many more deaths attributed to exposure.
- Lakhs of people suffered long-term health effects.
- It’s considered one of the world’s worst industrial disasters.
Causes
- Safety systems were not working or were inadequate.
- Cost-cutting and poor maintenance.
- Dense population near the plant.
Compensation
- In 1989, Union Carbide paid 470 million dollars in a settlement with India’s government, widely criticised as too low.
- Victims received small amounts after long delays.
Legal legacy
- The Public Liability Insurance Act, 1991.
- The Supreme Court’s absolute liability principle (from the 1986 Oleum gas leak case) holds hazardous industries fully liable.
- Toxic waste at the site remained for decades; some was removed in 2025.
Lesson
Weak safety, regulation and liability can cause catastrophic harm.
The night of the leak
Families near the plant woke choking on gas in the night, many dying as they fled through the streets.
Thinking industrial accidents are purely bad luck
Bhopal involved failed safety systems and cost-cutting.
Key takeaways
- Methyl isocyanate leaked in Bhopal on 2-3 December 1984.
- Thousands died and lakhs were harmed.
- Union Carbide paid a 470-million-dollar settlement in 1989.
- It shaped India's liability law.
