A Rotherham steel plant is operating as normal today despite an overnight blaze which took six hours to extinguish.
The fire at Tata Steel's Aldwarke Lane site was discovered at 1am today and involved thousands of litres of oil.
At the height of the blaze there were 10 fire engines and more than 50 firefighters at the scene.
The fire broke out in a specialist building where hot steel is placed in a bath of oil to cool it down as part of the production process.
Nobody was injured in the blaze, which did not spread.
A fire service spokesman said: "The fire involves several thousand litres of oil, but crews quickly contained the blaze to one building.
"All on site personnel have been safely evacuated and there are no reports of any injuries."
An investigation into the cause of the fire is due to be carried out.
A Tata Steel spokesman said: "There was a fire at the Bright Bar Rotherham Facility
"There were no injuries and the fire was contained before being extinguished.
"An investigation into the cause of the fire, which happened during a normal steel treatment process, has been launched."
