Fire chiefs are still investigating the cause of a dramatic tyre blaze on Friday night.
Residents across Hyndburn were told to keep their windows closed as smoke towered into the night sky until the early hours of Saturday, July 4, following the huge blaze off Accrington Road, Hapton.
Dozens of firefighters from Hyndburn, Burnley and Padiham battled for eight hours to extinguish the Frank Owen Commercial Vehicle Spares blaze, which was visible for miles around.
John Taylor, of Lancashire Fire and Rescue Service said: “We are still yet to establish the cause of the fire, with a fire of this size it is a case of sifting through all the debris to try and establish the cause.”
A Lancashire Fire and Rescue spokesman said: “A large quantity of tyres across a 50 by 100 metre area was on fire at recycling plant.
“Eight fire engines and aerial ladder platform and crews were in attendance.
“Firefighters prevented the fire from engulfing a building on site and stopped the blaze from spreading beyond the tyre stack.”
They added: “No-one was injured and the cause of the fire has yet to be established. On Saturday three fire engines and one aerial ladder platform and crews, with water jets, two ground monitors and four mobile jets in use.
“Firefighters were damping down, turning over smouldering debris using on site machinery.”
Accrington Road was closed between junction nine of the M65 and Rossendale Road for several hours.
