Two men have been taken to hospital after a five vehicle collision on the M6 south - which caused 150 litres of paint thinner to spill out on to the road.
Fire crews and ambulances were called to the scene between Junction 4 and 5 just after 5.40am following reports of the crash involving four lorries and a car.
The collision had caused one of the lorries to leak 150 litres of paint thinner onto the carriageway.
A 38-year-old man, the driver of the car, was taken to Heartlands Hospital with head and neck pain.
Three crews from West Midlands Fire Service have been working for three hours to clear the scene, with firefighters having to use breathing apparatus to ensure their own safety.
Traffic being topped for an hour caused tailbacks which were reported as far back as Junction 10 for Wolverhampton, with delays of up to two hours.
A spokesman for West Midlands Ambulance Service said:
“We received a call at 5.41am to reports of a multi-vehicle collision. A 38-year-old man was driving a stationary car when a lorry went into the back of the car, causing rear damage. The man complained of head and neck pain and was taken to Heartlands Hospital. The collision caused one lorry to leak 150 litres of paint thinner onto the carriageway. A second patient was also taken to Heartlands Hospital.”
West Midlands Fire Service confirmed that 15 firefighters were sent to the crash, with crews from Bickenhill, Ward End and Erdington. A spokesman added:
“We received a call from the Highways Agency at 5.43am to reports of a collision between two articulated lorries, two other lorries and a car. Two men were conveyed to hospital by ambulance but their injuries are not thought to be serious. We erected a safety cordon and worked to clean up the spillage, with four firefighters wearing breathing apparatus. All fire engines have now left the scene, but one crew from Erdington remains on the site.”
