Hazira terminal has five petrol storage tanks and four diesel tanks.
This is the second major fire at IOC storage depots since 2009. In 2009, a fire had broken out at its Jaipur terminal that raged for 11 days, killing 11 people, and causing losses worth Rs.280 crore.
IOC sources said senior company officials are in Hazira to supervise operations and an inquiry has been ordered into the incident.
