Emergency services battled with an incident at a former Teesside chemical factory on Tuesday (July 12) evening - as firefighters, paramedics and police officers were seen on the site.
Police cars were spotted closing off the road at the Seal Sands Roundabout at around 8pm after a reported incident at the former INEOS Nitriles on Seal Sands Terminal, Billingham.
Five fire engines attended the incident, which was thought to involve a plume of smoke coming from an industrial tank.
However, following further investigation work, firefighters found that the plume was thought to be 'non-toxic'.
A spokesperson for Cleveland Fire Service said: "We were called to an incident on 12/07/2022 at 7pm at INEOS on Seal Sands Road.
"Five fire engines were in attendance from Billingham, Stockton, Middlesbrough, Guisborough and Grangetown.

Firefighters were still seen at the site at around 11.30pm.
At the time of the incident, the site was thought to be under construction after INEOS closed the facility following the government's refusal of funding.
Other emergency services such as Cleveland Police, Harbour Police and North East Ambulance Service were in attendance.
The North East Ambulance Service has added there are "no injuries" related to the incident, but a hazardous response team were on standby.
A spokesperson from the North East Ambulance Service added: "We were called at 7.55pm to support the fire service at an incident on Seal Sands Road. We've got one hazardous area response team crew on standby, but there are no injuries."
Cleveland Police has been contacted for further comment.
