Update to follow within half an hour.
The ACT Fire Brigade is continuing to conduct atmospheric monitoring throughout Mitchell.
The by-product of the substance being burned, PCB, is a smoke plume that potentially could contain Phosgene.
Phosgene is known to cause irritation to skin and eyes, sore throat, nausea, headaches and dizziness, vomiting, chest pain and difficulty breathing.
The ACT Fire Brigade believe the risk to the community is low but continue to take all precautions.
People within a 10k radius of the fire are still advised to remain indoors with windows closed.
People outside this zone are strongly advised to stay away from the area and the smoke plume.
More information to follow.
ACT Education and Training Directorate is currently working to determine the impact of the fire on schools on the northside today. Further advice will be provided as soon as possible.
