A fire broke out at Swansea University’s £450m Bay Campus, with footage from the scene showing huge plumes of thick black smoke.
Fire services were called to the university campus in Skewen, Swansea, on Wednesday evening.
In a tweet at 6.44pm, Mid and West Wales Fire and Rescue Service wrote: “We are currently in attendance at an incident in Fabian Way, Swansea please avoid the area at this time.”
The incident came as students prepare to head to university next month after receiving their A-level results on Thursday.
Swansea University said the fire has now been extinguished and had been contained within the engineering department.
No-one is believed to have been inside the building at the time and there were no injuries, it added.
It is not known what started the blaze.
Site security manager Julian James told WalesOnline that a member of his team had seen smoke coming from the site at 6.08pm and fire crews were there within six minutes.
“The last staff members, cleaners, had clocked out at 5.45pm and security were on their way to lock the building.
“At the moment we are trying to assess the situation to establish the cause if the fire.
“It was isolated to one area, but we don’t know the extent of the damage yet.”
I am very grateful to everyone from @mawwfire and @SwanseaUni for such a fast response to a fire at one of our buildings this evening. The fire was thankfully tackled very quickly. The University will be operating tomorrow as planned. pic.twitter.com/hM2MmYtnSH

The university said its campus is now operating normally and thanked firefighters for their “swift response”.
The Bay Campus, which was built in 2015, is home to its engineering and management departments, as well as computer facilities for the university’s maths and computer science students.
There is also student accommodation on campus.
Swansea Council leader Rob Stewart said he was “relieved” the fire had been brought under control.
“My thoughts are with everyone at Swansea University,” he said.
