Officials said the fire appeared to have started in a warehouse storing tissue paper and spread from there to a chemical storehouse. The entire park was evacuated at around 7 p.m., and people living nearby were advised to stay inside with windows closed.
No injuries were reported.
About 150 firefighters were on the scene, The Guardian said.
"You can see the flames from miles around and there is smoke everywhere," Graham Thompson of Lostock Hall told the Post. "You can see constant flames and I can also hear little explosions going off. I just hope no one is still in there."
