A suspicious fire in a shed full of rubber tyres was continuing to burn on Friday morning at an industrial estate south of Brisbane, sending plumes of smoke over Logan.
The shed caught alight at the property on Koplick Road, Park Ridge, just before midnight Thursday.
A neighbour or passerby noticed the outbreak and called firefighters.
Fourteen crews worked through the night to contain the blaze.
Queensland Fire and Emergency Services Inspector Mark Buchard said the fire had created thick smoke.
Residents in Park Ridge, Marsden and Crestmead were asked to close their windows and doors as a precaution.
“Unfortunately due to the nature of the product that is burning they will generate a lot of smoke and they will do for some time,” he said.
“Our scientific unit is monitoring the smoke and their readings are all within safe readings, so the smoke is perfectly safe at the moment.
“Their advice is they will smell an odour, which is to be expected, but all levels are safe, there is no harm in the smoke.
“We have contained the fire at this stage, so it is just going to be a long process of overhaul and extinguishment due to a fairly substantial size area of tyres that is around the back of the premises.
“Crews are commencing damp down and hopefully we are expecting heavy machinery on site this morning to start removing sheet metal from the roof after structural collapse so crews can start working their way through the remains and extinguish the fire.”
The cause of the blaze is being treated as suspicious and a crime scene has been declared.
