In an incident that evoked memories of the deadly Bhopal gas leak, 12 people were killed and thousands reported sick after a gas leak from a chemical plant of a multinational firm in Andhra Pradesh’s Vishakhapatnam.

The gas, believed to be styrene, leaked from the plant of LG Polymers facility located near Vishakhapatnam at 3 am on May 7. This brought back memories of the 1984 tragedy in Bhopal where methyl isocyanate gas leaked from a Union Carbide plant killing more than 5000 people and causing severe and permanent disabilities to thousands of people.

Here’s all about the Vizag gas leak:

ACP West Zone Visakhapatnam told News18 that the gas leaked out from two 5,000 tonne tanks, which had been unattended since March due to Covid-19 lockdown. “It leads to a chemical reaction, and the heat was produced inside the tanks, which causes leakage.”
