Category: Madhya Pradesh Gk

Hint: Consider the historical event and the specific chemical that caused the disaster.

Correct Answer: A) Union Carbide, Methyl isocyanate.

Exam Relevance: UPSC, SSC, Banking, Railway

Difficulty: Moderate

Explanations:

The Bhopal gas tragedy is one of the most significant industrial disasters in history. It occurred on the night of December 2, 1984, when a gas leak from the Union Carbide India Limited (UCIL) pesticide plant in Bhopal, Madhya Pradesh, India, released methyl isocyanate (MIC) into the atmosphere. The gas cloud spread over a large area, affecting more than 30 square miles and causing widespread casualties and long-term health issues.

The disaster was caused by a series of operational and maintenance failures at the UCIL plant. The gas leak was the result of a runaway chemical reaction that occurred when water entered a storage tank containing MIC. The resulting gas cloud was highly toxic and caused immediate respiratory distress, eye irritation, and other severe health effects. The exact number of fatalities is disputed, but estimates range from several thousand to tens of thousands of people.

The Bhopal gas tragedy highlighted the need for stringent safety measures in industrial plants, particularly those handling hazardous chemicals. It also brought attention to the importance of disaster preparedness and the need for effective emergency response plans. The incident led to significant changes in safety regulations and corporate responsibility in the chemical industry.

The chemical involved, methyl isocyanate (MIC), is a highly reactive and toxic compound used in the production of pesticides. It is particularly dangerous because it can cause severe respiratory and ocular damage, as well as systemic effects that can lead to long-term health issues. The release of MIC in Bhopal was unprecedented in its scale and impact, making it a landmark event in the history of industrial accidents.

Understanding the Bhopal gas tragedy is crucial for comprehending the potential risks associated with industrial operations and the importance of safety protocols. It serves as a reminder of the need for vigilance and preparedness in managing hazardous materials and the potential consequences of negligence in industrial safety.

Option Analysis:
  • Option A: This option is correct. The Bhopal gas tragedy involved a leak of methyl isocyanate (MIC) from the Union Carbide India Limited (UCIL) factory. The gas cloud covered an area of more than 30 square miles and caused thousands of deaths and injuries.
  • Option B: This option is incorrect. The Exxon Valdez oil spill occurred in Alaska and involved the release of crude oil, not a gas leak. The chemical mentioned, methane, is not associated with the Bhopal disaster.
  • Option C: This option is incorrect. The Fukushima Daiichi nuclear disaster involved a nuclear meltdown and the release of radioactive materials, not a gas leak of methyl isocyanate. Carbon monoxide is not the chemical involved in the Bhopal tragedy.
  • Option D: This option is incorrect. The correct information is provided in Option A, which accurately identifies the company and the chemical involved in the Bhopal gas tragedy.

Mnemonic: Bhopal, Union Carbide, MIC (Methyl Isocyanate)
