A road has been closed in Ellesmere Port following a crash between two oil tankers.
Emergency services, including an air ambulance, are currently dealing with the incident on Oil Sites Road, just off the M53 near the Boat Museum.
The driver of one of the tankers is currently being treated for 'serious injuries'.
Police closed Oil Sites Road in both directions between the Dock Yard Road junction and the Pool Lane junction at around 1pm this afternoon (Thursday).
It is likely to be closed for some time after one of the tankers has overturned and leaked around 7,000 litres of petrol on to the road.
Firefighters are putting foam across the spill and have a covering jet in place.
Four fire engines from Chester , Ellesmere Port and Runcorn are currently at the scene.
Police are advising motorists to avoid the area.
A Cheshire Police spokesman said: “We received reports at 1.03pm of a two vehicle RTC between a HGV and an oil tanker.
“The road has been blocked in both directions.”
A Cheshire Fire and Rescue Service spokesman said: “Two appliances from Ellesmere Port, one from Runcorn and one from Chester have been sent to the scene.
"An estimated 7,000 litres of petrol has leaked from the tanker.
"A blanket of foam has been put across the petrol by firefighters, who are also damming drains and putting foam into a small gulley at the side of the road for environmental protection."
Anyone with any information in relation to the incident is asked to contact Cheshire Police on 101 quoting incident number 420.
