After the unit located in Santej area caught fire, some blasts occurred due to chemical barrels stored there which further escalated the blaze, a fire department official said.

The fire brigade received a call at around 2 am about the fire in the factory which manufactures solvent-based adhesives. The flames spread fast due to highly inflammable chemicals stored in the unit, he said. Eighteen fire tenders were rushed to the spot along with a remote-controlled fire robot that is used for areas where working manually is not possible, he said ''The fire had grown massive when we reached the spot. We have been able to control the blaze, barring some parts which are still burning due to the collapse of shed on them. There is no casualty,'' the official said.

The cause of the fire is not yet known, he said.
