ICSE Class 8 Answered

The Bhopal gas leak disaster was a man-made disaster due to faulty management and negligence. 

The disaster occurred in 1984 when about 45 tons of methyl isocyanate gas escaped from a plant owned by a subsidiary of Union Carbide Corporation. According to the sources, the leak was caused by operating errors, design flaws, maintenance failures, training deficiencies, and economy measures that endangered safety. 

The disaster could have been avoided, as it was preceded by multiple foreshadowing incidents. One of the causes of the disaster was an employee failing to insert a physical safety device. This caused water to leak through a valve, which led to the release of a chemical from the plant. 

The disaster killed at least 2,000 people and left thousands more with chronic health issues, including cancer, lung disorders, and neurological damage.
