Emergency services in Tshwane battled a blaze on Friday after 30 000 litres of ethanol caught fire at a factory in Sunderland Ridge, Centurion. Tshwane Emergency Services spokesperson, deputy chief Charles Mabaso, said: "When firefighters arrived at the factory where the ethanol was contained, it was already on fire, with the roof having collapsed." He said they managed to contain the blaze from spreading to the back of the factory, where another 50 000 litres of ethanol were stored in drums. Manufactured Mabaso said it was a "chemical factory", but they were not aware of what was manufactured in the factory.
