A cordon put in place in the Trafford Park area following a chemical leak was lifted late last night.
The leak was contained by the coordinated effort of company staff and emergency services working at the scene.
Fire officers worked with specialists on the site to contain the chemical leak, which is not believed to have spread outside the complex.
Emergency services were called to the chemical plant on Trafford Park shortly after 6.15pm on Friday 16 November 2012 and found that a chemical, hydrochloric acid, was leaking from the unit. Cordons were put in place as a precautionary measure in line with established emergency plans. These were lifted by around 11pm.
Superintendent Chris Ullah from Greater Manchester Police said: “Emergency services were working at the chemical plant at Trafford Park last night and isolated the leak. There were no reports of injuries or any people requiring medical attention.
“We then scaled down the emergency service response to return normality to the area as quickly as possible."
The cause of the leak is not yet known but will be investigated.
