A major fire broke out at PGI's Nehru Hospital in Chandigarh, late on Monday night.
A short circuit in the computer room is suspected to be the reason behind the fire.
This was the first such major fire incident in the hospital where over 480 patients, including 80 pregnant women and 56 babies, were evacuated safely.
The fire was swiftly extinguished, said a senior official, confirming that all patients were safe.
PGI director Vivek Lal along with senior faculty members besides fire and engineering wings reached the spot to provide the needed care and support required for patient care, the hospital said in a statement.
