Three people have been “contaminated” after coming into contact with an unknown substance on the Fylde coast, emergency services have said.
A specialist chemical detection team has been rushed to a building site on Normoss Road, Normoss, today when the workers were taken ill after coming into contact with the mystery gas.
Firefighters, police and paramedics were all called to the site, close to the junction with Avenue Road, at around 11am.
An evacuation of the area is believed to be underway while experts try to identify the substance, which has claimed three casualties.
A Lancashire Police spokesman said: “Three workers have been exposed to an unknown vapour and are being treated by specialist paramedics.
“It seems to be contained within the area and there is not thought to be any risk to the wider public.”
A spokesman for Lancashire Fire and Rescue said: “We got a call at 11.10am about a hazardous material incident, where three casualties were suffering from the effects of an unknown substance.
“It looks like a building site where people were digging and became contaminated.
“A detection and identification monitoring (DIM) team was also called from Merseyside.
“Police were called to evacuate the local area around Normoss Road and the ambulance service has set up a rendezvous point at the Newton Arms pub.”
At 1.30pm, a spokesman for the North West Ambulance Service said the casualties were being kept on site along with a specialist heart team.
Normoss Road is closed between Staining Road and Staining Old Road while investigation work takes place and police are advising people to avoid the area.
