Fifty firefighters have dealt with a “major” acid leak from a tank at a dock in Hull overnight.
Humberside Fire and Rescue Service said the tank on the quayside at King George Dock, near to the River Hull, contained 580 tonnes of hydrochloric acid.
The leak, which impacted the dock’s east side, led to people in the area being advised to close windows and doors as a precaution.
At about 04:20 BST, the fire service tweeted the leak had been contained.
A vapour cloud was created by the leak, but the wind direction took it away from nearby residential properties.
A fire service spokesperson could not say how much acid had leaked, but said the incident did not lead to any evacuations.
The Environment Agency said it did attend in the early hours of the morning, but at present there appeared to be no leakage into the Humber or any other environmental impact.
