Firefighters are investigating a blaze at a commercial workshop that involved two tonnes of tyres.
Five engines were called to Telford Way Industrial Park in Kettering, Northamptonshire just after 11:00 GMT on Thursday.
Gas cylinders and 40 litres of brake fluid were also involved in the fire at the site on Linnell Way.
Roads reopened earlier on Friday. The workshop remained cordoned-off while investigations took place.
Overall, ten appliances attended the scene yesterday after first being called shortly after 11am . Approximately two tonnes of tyres, two acetylene cylinders, two butane cylinders and one argon cylinder were involved in the fire as well as 40 litres of brake fluid. [5/5]
The county's fire service said in a tweet that after the fire was brought under control, "a number of cylinders have been heated up and still need to be cooled down".
Fire protection officers have been visiting neighbouring businesses as part of their inquiries, and to give fire advice.
