A rogue tyre recycling operator with a history of environmental breaches has lashed out at journalists at another fire at one of his businesses in Brisbane.

Tony Di Carlo's Tyremil businesses were subject to environmental protection orders last year, due to the Queensland Government's concerns about fire risks at his Rocklea and Kingston sites.

The ABC understands Tyremil was given until June 30 to comply with the orders or face the possibility of being shut down.

Emergency services were called to the Rocklea property on Grindle Road about 7:00am.

Mr Di Carlo was seen taping over company logos on vehicles at the site, and had to be restrained by police and a firefighter when he saw an ABC cameraman.

"F*** off mate — you f***ing ruin f***ing families' livelihoods," he yelled.

The cause of the fire is now under investigation.

It is the second blaze at the Rocklea site since 2016.

Health fears from noxious fumes

Queensland Health chief health officer Dr Jeannette Young warned tyre fires could produce very noxious fumes.

"These fumes can cause headaches and other symptoms and aggravate conditions like asthma, cardiovascular diseases and others," she said.

"Unless you are told to evacuate, stay indoors with your doors and windows closed.

"If using an air conditioner put them on recycle so that they are not drawing air in from outdoors."

Conviction for threatening former associate

In December, the State Government ordered Mr Di Carlo to safely store an estimated 800,000 tyres at his businesses.

Drone footage confirmed the growing stockpile of tyres during 2016, and there were concerns a fire could result in the closure of the nearby Archerfield Airport.

"If you talk to firefighters, they describe these kinds of things as giant stockpiles of solid oil, and that's effectively what they would become if we were to see a fire," Queensland Environment Minister Steven Miles said last year.

The State Government has been contacted for comment over the fire today.

In May this year, Mr Di Carlo was convicted of threatening a former employee and a former associate.

The 46-year-old left a series of abusive voice messages in the lead-up to the ABC airing stories about environmental concerns about his businesses.

He received an 18-month good behaviour bond and was ordered to continue counselling for anger and anxiety issues.
