A probe was underway today into the cause of a huge ongoing blaze on an industrial estate in Sheffield.
Dozens of firefighters have battled for hours to try to bring under control the fire on Station Road, Ecclesfield, and to save neighbouring businesses.
Station Road was closed while firefighters worked from 10pm on Wednesday and into yesterday. They expect to remain at the scene this morning.
The disused unit is full of plastics, and was engulfed in flames with plumes of thick black smoke billowing into the sky when crews arrived - prompting a warning to local residents to keep their doors and windows closed.
Residents are still advised by Public Health England to stay indoors and keep their windows and doors shut, and motorists were told to turn off air conditioning and keep air vents shut.
A spokesman said: “To date, there have been no reports of people experiencing ill effects from this fire.”
Flames spread to an adjoining car-spraying business, which suffered a significant amount of damage.
Businesses were still unable to trade yesterday, and staff sat at the cordon waiting for information from the fire service.
At the height of the blaze 40 firefighters and eight appliances were at the scene, including an aerial ladder platform used to douse the building from above.
Fire chiefs liaised with the Environment Agency and Public Health England to formulate a firefighting plan aimed at minimising pollution.
Local residents watched as emergency services raced to the scene, and saw ‘bright orange flames’ in the sky.
Barbara Cawthorne, of The Common, said: “I’m keeping all my windows closed, and staying inside as much as I can – the smell is so strong.”
