The Bhopal disaster is one of the world's worst industrial disasters in the history of mankind. The explosion at Union Carbide plant located at the heart of the city of Bhopal caused a release of toxic gas rolled along the ground through the surrounding streets killing thousands of people.
The gases also injured anywhere from 150,000 to 600,000 people. Six safety measures designed to prevent a gas leak had either malfunctioned, were turned off or were otherwise inadequate. In addition, the safety siren, intended to alert the community should an incident occur at the plant, was turned off.
