A spokesperson for Mid and West Wales Fire and Rescue Service said the incident at the Tata Steel site remains ongoing.

They said: "At 8.06pm on Wednesday, 3rd June, Mid and West Wales Fire and Rescue Service crews from Port Talbot, Neath, Morriston, Glynneath, Swansea West, Cymmer, Swansea Central, Pontardulais, Llanelli, Carmarthen, Ammanford, Gorseinon, Pontyates, Kidwelly, Haverfordwest and Milford Haven Fire Station were called to an incident at TATA Steel, Port Talbot Steelworks.

"This incident is currently ongoing, supported by colleagues from South Wales Fire and Rescue Service and Avon Fire and Rescue Service.

"The area should be avoided while the incident is ongoing to allow access for emergency services and local residents are advised to keep windows and doors closed if there is smoke in the area."

A Wales Online reporter at the Tata Steel site in Port Talbot has said the fire appears to have been extinguished.

Tata Steel issued a statement this morning confirming that all workers had been evacuated from the site and no one had been injured.

A spokesperson for the company said: "Mid and West Wales Fire Service attended the Port Talbot site last night at around 8pm to deal with a fire at one of the site’s processing lines.

"All personnel were accounted for and evacuated from the area safely. At this time, the emergency services remain on site and are working with local teams to completely extinguish the fire.

"The incident is not related to the safe and successful demolition of the empty, redundant Gas Holder earlier yesterday evening.

"We would like to thank local site teams and the emergency services for their prompt and professional action. Further updates will be shared as information becomes available."

Rapid Relief Team UK (RRT) said "around 100 responders faced an incredibly demanding and hazardous night's work".

Around eight fire appliances, two foam units, two high-reach turntable platforms and an HVP were used to tackle the blaze, RRT said.

Volunteers at the non-profit organisation served "125 hot meals through the night to keep crews fuelled as they continued their vital work".

Tata Steel said the fire was not linked to the controlled demolition of a old gas holder at the site yesterday evening.

The company thanked site staff and emergency services for their "prompt and professional action".

A resident in Maesteg said they could "taste" smoke in the air.

They said: "Black smoke is billowing from the site. All residents within the area and further afield such as Maesteg, where plumes of smoke are being carried by the strong winds this evening, should be warned to keep windows closed in case there is a risk to health. You can actually smell and taste it in the air in Maesteg."

Tata Steel began steel production in the eastern Indian city of Jamshedpur in 1912 and expanded globally through its acquisition of Corus in 2007.

Corus was formed in 1999 through the merger of British Steel plc - originally established as the nationalised British Steel Corporation in 1967 and privatised in 1988 - and the Dutch company Koninklijke Hoogovens.

Tata Steel carried out a controlled demolition of a gas holder at the Port Talbot site earlier on Wednesday evening.

There is no suggestion the demolition, which the company said was carried out safely, is linked to the ongoing incident at the steelworks. Local residents reported their homes "shook" when the gas holder was brought down.

Shortly after the demolition, the company said: "People working and living in the Port Talbot area may have just heard a loud noise emanating from the Port Talbot steelworks.

"This was the result of the planned demolition of the empty, redundant coke ovens gas holder, which has been completed safely as part of the ongoing engineering works on the site. The gas holder ceased operation with the closure of the site’s heavy-end in September 2024.

"This demolition was required to make space for future raw materials handling areas for the new three million tonne per year capacity electric arc furnace.

"Our thanks goes to the whole team involved from Tata Steel and our contractor partners Thompson of Prudhoe and PDC, in what was a complex programme of work. We apologise for any inconvenience caused."

A resident living on Beechwood Road in Port Talbot told Wales Online late last night: "The alarm has been going off from around 7pm, shortly thereafter we saw billows of smoke coming from the site directly towards our house.

"No residents here were informed of the controlled explosion that was going on in the works this afternoon at 6.30pm and we only knew about it after the blast. Tata posted about ongoing noise 20 minutes after the explosion.

"At one point this afternoon, you couldn't see the front gardens from the front windows it was so smoggy outside."

A spokesperson for South Wales Police said: "Emergency services are currently dealing with an incident at Tata Steel, Port Talbot. Large plumes of smoke are visible in the area.

"Residents are advised to keep windows and doors closed. Please avoid the area and use alternative routes where possible. Thank you for your patience."
