Scrap metal at MHH Contracting’s site on Carlisle Street, in Burngreave, went up in flames this afternoon, sending thick plumes of smoke billowing across the city.
South Yorkshire Fire and Rescue said it was called at around 1pm and initially sent three crews to the scene.
In an update issued shortly before 4pm, the fire service said the fire was still burning and there were now six fire engines at the scene.
"Please continue to keep doors and windows closed if there is smoke in your area,” it added.
“Luckily there are no reports of any casualties.”
The fire service said at around 5pm that crews were expected to remain at the scene ‘for some time’.
It said that firefighters were using four ‘monitor jets’ to tackle the blaze.
“An investigation will take place into the cause of the fire once it is out, “ it added.
First South Yorkshire said at around 3pm that Petre Street and Carlisle Street had both been closed due to the fire, with its number 32 and 32a buses being diverted as a result of the large blaze.
People have reported smelling the smoke at least three miles away.
One woman, commenting on Twitter, complained about the ‘horrendous air quality’ due to the fire, adding ‘look out for yourselves, folks’.
