UPDATE: A toxic industrial fire at a Torrington business is under investigation as Queensland Fire and Emergency Services continue dampening down the blaze.
Initial investigations suggested a Neil's Parts worker on Taylor St had cut through a steel rim which sparked a fire in a pile of large tractor tyres which quickly spread to other material onsite.
QFES Acting Chief Superintendent Eddie Lackos said the cause appeared to be accidental.
Multiple urban fire crews as well as specialist bulk foam units were called to fight the blaze which was brought under control within 45 minutes on scene.
"They're large tractor tyres so once they're ignited, they're difficult to put out," Act. Chief Supt Lacko said.
"It had the potential to spread into other parts of the equipment and other storage they've had there, but we've managed to isolate and contain it to its point of origin."
He said QFES had issued a community advice message to allay concerns in the wider community as the thick black plume of smoke continued to billow from the fire.
No firefighters were injured fighting the blaze.
"Any fires are intense and it puts up a lot of smoke," Act. Chief Supt Lacko said.
"It is a toxic atmosphere so we had crews close by but they were wearing breathing apparatus."
