PORT TALBOT: Steelworks fire burns into a second day as part of the building collapses — with union warning over jobs
The huge fire at Tata Steel’s Port Talbot works was still burning on Thursday, more than a day after it broke out — and crews are now battling a blaze that has buried itself beneath a collapsed building.
Part of the structure has caved in, making it far harder for firefighters to reach the flames, the Rapid Relief Team said after supporting crews at the scene.
A spokesman for the charity, which has been feeding responders throughout, said part of the building had “collapsed in” and that “a lot of machinery has fallen on top trapping the fire underneath.”

— Rapid Relief Team UK (@RRT_UK) June 4, 2026The fire broke out at one of the site’s processing lines at around 8pm on Wednesday. All staff were accounted for and evacuated safely, as more than 100 firefighters were thrown at the blaze through the night — crews drawn from 16 stations across south and west Wales, with reinforcements from South Wales and Avon.
By Thursday afternoon the picture had hardened from “ongoing” to something more serious, with confirmation of significant damage and a fire that was proving stubborn to put out.
The union Unite said the blaze had caused “substantial damage to a vital production line” — and moved quickly to put jobs at the centre of the story.
Unite general secretary Sharon Graham thanked the emergency services for bringing the situation under control so quickly, and said no one had been hurt and workers had been evacuated safely.
But she warned: “Measures must now be put in place to protect jobs both at Tata and down the supply chain during any period of disruption.”
She added that the union was asking Tata and the government to ensure that operations were “rebuilt as swiftly as possible.”
Unite Wales secretary Peter Hughes said the union was committed to working with the company to secure the long-term future of Port Talbot and the wider Tata operation in the UK.
The jobs warning lands in a town already on edge. Tata closed its two blast furnaces in 2024 with thousands of job losses, and is in the middle of a £1.25bn transformation of the site — switching to a greener electric arc furnace, with steel processing continuing in the meantime. A fire on one of those remaining lines is the last thing the workforce needed.
There was at least some reassurance for residents. Welsh Government monitoring showed air pollution in Port Talbot classed as low on Thursday, though officials note the effects of a fire can be localised — and South Wales Police’s advice for nearby residents to keep windows and doors shut still stands.

The Rapid Relief Team said it served around 150 hot meals through the night and a further 70 on Thursday morning to keep responders going, with firefighters, ambulance HART medics and high-volume pump crews all rotating through its support tent.
Among the stations that sent crews through the night was Ammanford’s Station 57, which said its firefighters had worked alongside colleagues “from across the Service” and thanked partners on site for their cooperation.
The works is no stranger to those crews. In January, firefighters scaled a 32-metre tower at the steelworks in a dramatic multi-agency rescue drill — an exercise designed partly to test Tata’s emergency protocols in a live industrial setting. Months later, the same teams were back fighting the real thing.
It is the second major fire to grip Port Talbot in barely five weeks. At the end of April, a huge blaze involving around 200 tonnes of commercial waste sent black smoke billowing over the town from an industrial site on Dock Road.
Tata Steel has stressed the fire was not connected to the controlled demolition of an empty, redundant gas holder carried out at the site earlier on Wednesday evening, which it called safe and successful.
The cause has not been established, and the company has said it cannot yet assess the full damage.
This is a developing story and we will bring you more as we get it. Anyone affected by smoke is advised to keep windows and doors closed.
