A blaze at a recycling centre started in a pile of old cars, firefighters have said.
Lancashire Fire and Rescue Service crews were called to Recycling Lives on the RedScar estate off Longridge Road at 9.40pm on Thursday.
The blaze broke out in a large heap of cars which were ready to be recycled. Crews are still on site.
A statement from LFRS said: “As the fire grew in size, 15 fire engines and other specialist equipment from across the county were called to the incident ground.
“This specialist equipment included aerial ladder platforms, a command unit and foam pods.
“Firefighters will continue to extinguish the fire as daylight breaks on Friday morning and the Service at 5:00am still had 15 fire engines and approximately 100 firefighters dealing with the fire. It is expected that firefighters will remain there for most of the day.
“An initial investigation into the cause of the fire began overnight and the cause has not been established so far.
“The service would like to thank all of our partner agencies who have helped us deal with this fire, including Greater Manchester Fire and Rescue Service who assisted by sending specialist appliances, Lancashire Police, North West Ambulance Service and United Utilities amongst others.”
