SAFETY guidelines have been issued to nearby residents as a week-long fire continues to blaze.
The wood chipping fire, at R Plevins and Sons in Crow Edge, started last Monday.
More than 3,000 litres of water per minute is being used to try to put it out, with fire crews building a makeshift lagoon at the site for water to run off into so it could be recycled and to alleviate concerns of stopping polluted water running into the River Don.
A spokesperson from Public Health England said: "Sheltering indoors provides protection from exposure to smoke, so we advise residents in any areas affected by smoke to keep doors and windows closed as much as possible to limit any exposure to smoke.
"Motorists who have to travel through any smoke should keep windows closed, turn off air conditioning and keep their air vents closed."
