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.
