Canberra firefighters hope they will be able to extinguish a huge chemical fire in the Australian capital by Saturday.
The fire broke out at a building in an industrial estate at Dacre Street in the northern suburb of Mitchell about midnight on Thursday, sending a plume of potentially toxic smoke streaming the city.
Fire crews initially brought the blaze under control, but were forced back by a series of explosions which witnesses said sent flames shooting up to 200 metres into the air, the ABC reports.
Emergency services say the fire has been contained within the Mitchell industrial site by late afternoon on Friday.
Atmospheric monitoring shows one possible toxin indicator has been detected, but authorities say it is well within safe limits.
There have been two reported minor injuries and some minor leakage of water used to fight the fire into nearby ponds.
Emergency services say the smoke is potentially toxic but the risk to the public has been described as low. However, residents in Mitchell have been told to stay indoors.
