The blast was so powerful that it was heard by people a long distance away from the spot, the official said. “At least 20 workers were injured. Eight of them are admitted in hospitals in Bharuch and Ankleshwar, while 12 others were discharged after initial treatment,” he said.
Around 15 fire tenders were rushed to the spot and the blaze was brought under control by around 6.30 am, he said. Rescuers have not been able to enter the unit due to excessive heat in the premises, but they are still trying to get in, the official said. The cause of the fire is yet to be ascertained, he added.
