FOUR fire crews spent nearly two hours clearing up a chemical spill at Tilbury Docks this afternoon (Tuesday).

Crews from Grays and Orsett were called at 3.11pm after a valve on a tank broke and ethanol, a volatile and flammable liquid, started to leak.

A spokesman for Essex Fire and Rescue described the ethanol “pouring” from the container which can hold up to 33,000 litres of the liquid.

The firefighters laid down a blanket of foam to prevent risk of ignition and contain the spillage while the Port of London Authority brought a new container to put the remainder of the liquid into.

The ethanol was moved safely into a new container and was secure by 5pm.
