On the morning of April 23, 2008, his father replaced the used empty cylinder. While fixing the regulator, the pin inside the neck of the fresh cylinder slipped, resulting in leakage of gas. When the electric light was switched on, a fire broke out. At this time, Rao was on duty. His father, mother, wife and two daughters, who were in the house, suffered serious injuries and had to be shifted to hospital. Later, his father, mother and daughter passed away.
