Residents are being urged to keep windows and doors closed as a change in wind direction blows fumes from an industrial fire over a town.

Anyone living or working in or around the Dane Valley area of Margate is being warned to protect themselves against the fumes coming from the fire in Westwood.

Crews are entering their fourth day of tackling flames, which started in the former Cummins Power Generation building in Star Lane on Saturday morning.

The cause of the fire is not yet known but the site is full of flammable waste, has been alight for hours.

Ten engines were called at about 6.20am, but the number increased to 14 as crews battled the fire.

At its height, 80 firefighters were battling the blaze, but the number of fire engines present has now reduced to seven.

The significant heat from the fire caused a partial collapse of the roof and a wall.

The advice from Public Health England for people living and working in areas affected by smoke is to stay indoors and keep doors and windows closed.

Motorists who have to travel through the smoke should keep windows closed, turn off air conditioning and keep their air vents closed.

Some of the substances present in smoke can irritate the lining of the nose, throat and lungs, the skin and the eyes.

Symptoms may include coughing and wheezing, sore throat, feeling short of breath, runny nose or eyes or chest pain.

In general, exposure to smoke is more likely to affect people who have existing breathing problems, lung or heart conditions.

People who are generally fit and well are unlikely to experience long-term health problems from temporary exposure to smoke from a fire.

The very young and very old, smokers, and people with flu or flu-like illnesses, may also be at greater risk after exposure to smoke from fires.

To minimise exposure, people should limit the amount of time spent outside in the smoke.

People with asthma who may be in the vicinity of the fire should carry their inhaler.

If symptoms persist, seek medical advice by calling NHS 111 or by contacting your GP. In the case of an emergency call 999.
