Fire crews have continued to tackle a serious warehouse fire which broke out on Friday at the Aycliffe Industrial Estate in Newton Aycliffe.
The area around the Stillers premises is still cordoned off.
The fire service says it expects the fire will finally be extinguished today.
An investigation into its cause will then take place.
No one was injured.
The fire broke out around 1300 GMT on Friday when there were reports of an explosion. People living nearby were advised to stay indoors.
Local residents are still being advised to avoid the smoke if possible; the Health Protection Agency says it can irritate the eyes, skin and the linings of the airways. If anyone experiences any health problems they should contact NHS Direct.
