ESA is managing the fire at Canberra Concrete Recyclers from an environmental and smoke hazard perspective.
Fire crews will be on site for the rest of the day putting out the fire and will reassess the situation this afternoon.
The weather conditions today means the smoke is staying low and the strategy of fire crews is to produce as little smoke as possible.
Most of what is seen today will be steam in the air.
Residents concerned about their health should contact ACT Health for advice.
The fire has been contained with on site heavy equipment being used to reduce the amount of material on the fire.
Several ACT Fire & Rescue fire trucks including specialised compressed air foam tankers remain in scene.
At this stage it is expected the fire will continue to burn for several days with smoke still being produced and spread away from Pialligo depending on the weather conditions.
People in areas where the smoke is present who have breathing difficulties should remain indoors.
