HYDERABAD/NEW DELHI, Aug 22 – Workers at a pharmaceutical factory in southern India were trying to plug a chemical leak when an explosion ripped through it, killing at least 17 people and injuring 36, the firm’s chief financial officer said on Thursday.
Wednesday’s blast came around noon at the privately-held Escientia Advanced Sciences in Andhra Pradesh, where nearly 400 employees make intermediate chemicals and active ingredients for export to the United States and other Western countries.
“It looks like it happened from a solvent leak,” said Srinivasa Rao Korada, chief financial officer of the Escientia Group, adding that it was not clear what triggered the leak.
“Workers had noticed that leak, they were attending to it, and had almost plugged the leak when this happened,” he told Reuters by telephone.
One of the worst industrial accidents in recent years in India, often called the pharmacy of the world, came a year after a fire at a pharmaceuticals factory in the same Anakapalli district of the state killed two people and injured five.
The company is collaborating with authorities to investigate the reason for the leak, Korada said, adding that smoke and fire had prevented the company from investigating immediately.
Officials said they were scanning closed-circuit television footage and questioning the injured to decide if human error was responsible.
“Preliminary investigation shows … there was some vapour leak that led to chemical reactions, which caused the explosion,” said state Industries Secretary N. Yuvaraj, who identified the solvent involved as methyl tert-butyl ether.
