Three people were injured at the Indian Institute Of Technology –Bombay (IIT-B) on Friday when a balloon they were filling with hydrogen, burst in a laboratory. The three sustained burns and are undergoing treatment at the National Burns Centre in Airoli. But the incident has raised concerns over safety precautions taken at the premier technology institute in Powai during experiments.

The incident occurred at around 12.30 pm in the laboratory of the Aerospace Engineering Department. While one of the three, Tushar Jadhav, 28, is a former student of the Aerospace Engineering faculty, he is currently a part-time staffer. The other two - Rajat Kumar, 22, and Prashant Singh, 22, both non-IITians - work for him at Manastu Space, a start-up he began.
