Four technicians working with Reliance sustained serious burns after a transformer exploded in Govandi yesterday. One of the four sustained 100% burns, while the others sustained 80%, 60% and 50% burn injuries.

According to the Govandi police, supervisor Vishwas Oak (55) and staffers Ramesh Gaddam (40), Shailesh Rane (35) and Anant Ghag (52) had gone to put oil in the transformer at the 11,000-volt sub-station as part of repair work at 10.30 am. When they went to switch off the transformer to put the oil, a massive explosion occurred. Four of them were flung away and a fire broke out in the sub-station.
