The Bhopal gas tragedy was the worst industrial disaster, where 40 tons of toxic gases leaked from a Union Carbide pesticide plant in Bhopal, India, exposing over 500,000 people. Thousands died within days and many more developed serious health issues. Contributing factors included unsafe storage of chemicals, disabled safety systems, and the plant's location near a dense residential area. While over $500 million was awarded in compensation, most victims received very little and continue to suffer health and financial impacts decades later due to ongoing contamination. The disaster highlighted the need for improved emergency response planning and hazardous materials handling.
