The patients of the two adjacent wards were evacuated immediately by two senior resident doctors present in the unit at the time of the incident last evening with the help of security guards.
No one was hurt in the fire though properties including furniture and equipment were damaged, the sources said.
While the exact cause behind the fire is yet to be ascertained, it is believed that it broke out due to a short circuit in the AC in the cabin and soon the two adjacent male and female wards were filled with smoke, sources said.
