The flames engulfed S R Chagada Chemical Factory in the wee hours, Fire Department official V P Singh told reporters here.
"Twelve fire tenders were rushed to the spot to douse the flames. The flames were too high as it took more than 2 hours to bring the situation under control," he said, adding that a major tragedy was averted as no one was present in the godown.
He said that the godown was constructed illegally in a posh locality and the incident has triggered panic among the residents.
