The nightmare continues for anyone who lives or works in the vicinity of the tyres recycling plant which went up in flames in Littleport last month.
Now they are being urged to keep their properties sealed as a change in wind direction is causing smoke to blow over the village.
Around 2,000 tonnes of tyres caught fire nearly five weeks ago at tyre recycling plant Murfitts, but residents and businesses are still being affected.
Cambridgeshire Fire and Rescue Service is advising people to keep their windows and doors closed over the next two days as the wind will change to a westerly direction.
Deputy Chief Fire Officer Chris Strickland said: “Although we are keen to continue our firefighting operation at the pace we have been in order to get the fire out as soon as possible, we also want to ensure we do not generate more smoke through our operations while the wind is blowing over the town.
“Therefore we will continuously review the effect of the wind direction change and if necessary we will modify our operations accordingly.
The Health Protection Agency (HPA) is also reiterating its health advice to the people.
Dr Kate King from the HPA said: “The general advice remains that people should do all they can to stay out of the smoke.
“If the smoke is blowing in your direction you need to take shelter.
“Staying indoors with the doors and windows closed will provide a good level of protection.
“People should remember that smoke is an irritant, so it can make your eyes and throat sore.”
