More than 40 firefighters from across Lancashire and Greater Manchester tackled a severe fire at an industrial site in Chorley overnight.
Lancashire Fire And Rescue Service received “dozens” of calls reporting the fire at Yarrow Business Centre, at Yarrow Mill, on Yarrow Road.
The blaze started just after midnight in an industrial unit and spread to two other units.
A fire service spokesman said: “Due to the amount of calls we received - we must have had dozens - instead of sending our normal response we sent four fire engines straight away.”
Two further fire engines also attended, meaning there were firefighters from Chorley, Bamber Bridge, Leyland, Preston, Blackburn and Horwich there.
The industrial unit involved was well alight when crews arrived.
They were told there could be acetylene cylinders and flammable liquid in the building, so they withdrew to a safe area.
The spokesman said: “We then called for an aerial ladder platform which was designed to get water onto the fire from above from a safer position.
“Also firefighters were then further sent into the building and they were crouched behind partitions so if there was an explosion, they would be in a safer position.”
By 3am the fire was under control and firefighters entered the building to extinguish it completely.

An acetylene cylinder was found in the building but was not thought to have exploded.
The blaze was officially out by 4.20am, but crews remained at the mill this morning.
An investigation into the cause of the fire is now underway.
There were no casualties in the fire.
