Confirming the explosion, that took place around 3.45 pm, Manish Bharadwaj, Defence Research and Development and Organisation (DRDO) spokesperson said, “It occurred when an experimental propellant composition was being mixed around 3.45 pm. The roof of the building was blown off. We have to assess all factors. If any residue is left, we have to clean the site.”

Later, HEMRL issued a press note saying, “HEMRL scientists were processing experimental propellant composition in a mixer in the laboratory premises. During the mixing process an explosion occurred today at around 3.45 am. The mixing process is remotely controlled and located in a standalone building outside the traverse. All safety norms were followed and nobody was in the mixer room. The building is heavily protected with soil filled traverse and designed in such a way that the roof is weak. In the explosion the roof of the building was blown off. However, there is no casualty, no one is injured and there is no damage to the facility.” Standing Safety Board of HEMRL is conducting an enquiry, it was stated.

Meanwhile, Deputy Commissioner of Police (Zone IV) Mahesh Patil said, “A police team from Chatuhshrungi police station was dispatched to the site after the HEMRL authorities informed us about the blast.

Inspector Mahadev Chavan said, “Prima facie it is known that nobody was injured during the explosion. Details would be available only after our team returns from HEMRL.”

The impact of the blast was felt in surrounding areas. Bhagvan Nivdekar, a resident of Pashan said, “There was a loud noise. When the ground and roof of our house shook, we thought it was an earthquake.”
